Using WifiWave2 to bridge two Audience wirelessly, thoughts? == 4-address mode

Sun Nov 14, 2021 8:42 pm

Trying the wifiwave2 package on the Audience using v7.1rc6. My goal was to bridge two Audience devices using the 3rd 5Ghz "mesh" interface of the devices, while using newer wireless package on the "client" Wi-Fi interfaces. Basically want to test just bridging one LAN between the two units wireless; with the non-mesh Wi-Fi also just bridged to same LAN. Ideally being able to use VRRP on the bridge, so either LTE interface could provide internet if separated. This is obviously possible using standard Wi-Fi package, but was trying to see if possible someway using wifiwave2.

At the start, I actually though this be straightforward: set "station-pseudobridge" mode on "mesh" wi-fi interface on one of the Audiences, and I'd be done. Assuming all interfaces are just bridged on both units. But there is only "station" mode in wifiwave2, so not so simple. Certainly using ap on one, station on another does just connect. But the "mesh" wifi interface are ports of the bridge interface, the ONLY traffic that passes are the "Neighbors"/CDP broadcast but ARP goes unanswered so anything IP fails. Changing the ARP mode of the "mesh" wifi interface had no effects – tried them all (proxy-arp, local-proxy-arp, enabled, & disabled even) , in all combos on both sides, just in case. I would have though at least the far end of the wifi link would work, but if the connected router does not respond to requires for it's own IP. Basically it seems once a wifiwave2 "station" goes into a bridge, ARP doesn't work, at all.

Removing the "mesh" wifi interface from the bridge, assigning IPs and routing between the two Audience does work - so the "station" to "ap" does seem to work at 802.11-level. But my goal is bridge ONE L2 LAN between the two units, not just have them do L3 routing between them.

Not detoured, and curious to see if there was at least someway to make this work. My next idea was to use a EoIP tunnel (sorta like DTLS tunnels used CAPsMAN) over the non-bridge "mesh" interface, then add the EoIP tunnel to the bridge. This does in fact work, but obviously MTU is squashed. I ran into another issue with wifiwave2 in that it seemingly doesn't allow the MTU to be changed (or perhaps the UI/CLI doesn't correctly reflect the change) – for my testing, I just changed the EoIP tunnel to 1500 MTU.

Obviously the EoIP tunnel isn't ideal and I suspect I've run into bugs/limits of the wifiwave2 package. So perhaps this is just a feature request for "station-pseudobridge" in wifiwave2 package.

Be also curious if I'm missing something/someway to bridge between two Audience using wifiwave2, to eventually eat some CAKE ;).

I'll post the configuration, but basically I think there are still some bugs/missing things in wifiwave2...

Couple side notes:
1. The MTU docs don't specifically mention the Audience: https://help.mikrotik.com/docs/display/ ... n+RouterOS
2. Out of curiosity, I'm not sure ip/packing does anything in v7.1rc6 - though it be radically different way to clamp L2 MTU and/or reduce packet sizes, curious at CPU/latency for the compression on something more powerful like the Audience. But didn't seem to work, even though the interfaces I tried were all "neighbors".

I don't have wifiwave2 device so I can't check if there's really no station-bridge mode. You should avoid station-pseudobridge. For 2 nodes using mesh is overkill.

Best improvization I can think of is EoIP tunnel over the wifi connection using the IPs you have assigned to the interfaces. Just be mindful that EoIP + parallel IP path may cause weird effects, maybe you want to filter all IP traffic between the station and the AP and leave only the EoIP one.

Well, I was kinda hoping I just might be able to drop the wi-fi interface on both sides into the bridge, and have ROS "do the right thing" (e.g. infer some wifi bridging mode) based on the "station" being a bridge port member – no such luck. But @gdanov station-bridge is closer to what I was expecting exist in wifiwave2.

That's a very fair concern - hadn't dissected the packet flow diagram. But my bigger concern is I'm not sure the wifiwave2 MTU can go above 1500. This is a problem since any tunnel has overhead, with EoIP +42. Since so for the "wireless bridge" between the two Audience units to avoid fragmenting/cramping-MSS, the wifiwave2 interfaces needs >1542 MTU.

The photo above shows my concern, which appears to a bug in v7.1rc6 – winbox shows the "Actual MTU" as "1500". But I can't find "actual-mtu" in the CLI, so hard to know if just a "winbox things"...

But since I also tried using a VxLAN approach, instead of EoIP, it also thinks the MTU of the wavewifi2 interface is 1500, so it limits the VxLAN MTU to 1450. The following CLI snippet shows my MTU concerns, since EoIP would need a higher L2MTU (>1542) over the "wifi bridge" to avoid reducing MTU on either side:
[skyfi@M172-Rizi] /interface/vxlan> export
# nov/17/2021 17:43:05 by RouterOS 7.1rc6
# model = RBD25GR-5HPacQD2HPnD
/interface vxlan
add group=239.11.37.100 interface=wifi-MeshStation mtu=1450 name=\
    vxlan-skybridge port=8472 vni=100
[skyfi@M172-Rizi] /interface/vxlan> print detail 
Flags: X - disabled, R - running 
 0 R name="vxlan-skybridge" mtu=1450 mac-address=EA:D5:A5:1A:C5:73 arp=enabled 
     arp-timeout=auto loop-protect=default loop-protect-status=off 
     loop-protect-send-interval=5s loop-protect-disable-time=5m vni=100 
     group=239.11.37.100 interface=wifi-MeshStation port=8472 
[skyfi@M172-Rizi] /interface/vxlan> set 0 mtu=1500
failure: could not set mtu
[skyfi@M172-Rizi] /interface/vxlan> set 0 mtu=1451
failure: could not set mtu
[skyfi@M172-Rizi] /interface/vxlan> set 0 mtu=1449
[skyfi@M172-Rizi] /interface/vxlan> set 0 mtu=1450
Now so far the EoIP tunnel over WifiWave2 does seem to work & seems stable from logs. In fact, since only one has an active LTE connection to internet, the 2nd audience needs to wireless link to get to the internet. I've also had ZeroTier enabled on both Audience in my testing here, that seems to be work the few times I tried from my Mac over the internet (with ZeroTier Mac client connected to same ZT network).

But the MTU issue is my first concern – but what's going with the [un]packing of the EoIP tunnel in the bridge is worth more look too. Basically, I think there are still some bugs in WifiWave2...

They need to add "four address frame support" into wifiwave2 before it will support bridging.

No doubt, seemingly why only "station" is supported - more testing to find these things out ;).

But the MTU should be settable >1500 since 802.11 MTU is >2000. In my use case, being able to trunk VLANs over EoIP (or using a set of VXLANs to carry individual VLAN using Bridge "VLAN Filtering") to tunnel inside a ap-to-station wi-fi link isn't necessarily the worst approach – it's just I rather not have the MTU compressed/fragmented by the tunnel, especially since 802.11 has a higher possible MTU than being allowed by the wavewifi2 package.

This can't come soon enough.. I invested in 3 audiences and regretted it since.
Cannot get more than around 160Mbps between them even if they are in the same room!

Is it feasible to use MPLS/VPLS for better performance than EoIP? It is often done in PtP to have higher speed.
MPLS/VPLS needs a larger MTU, or the inner MTU should be reduced accordingly. (A smaller MTU, leading to smaller MSS, does not lead to fragmentation and is not so bad for performance).

Re: Using WifiWave2 to bridge two Audience wirelessly, thoughts?

Mon Jan 10, 2022 9:08 pm

Is it feasible to use MPLS/VPLS for better performance than EoIP? It is often done in PtP to have higher speed.
MPLS/VPLS needs a larger MTU, or the inner MTU should be reduced accordingly. (A smaller MTU, leading to smaller MSS, does not lead to fragmentation and is not so bad for performance).

Dutch video: https://www.wirelessinfo.be/mikrotik-po ... p-vs-mpls/

Just thoughts !
MPLS+VPLS, now that's cleaver for a PtP link. Didn't try, but had a wacky idea to use IP>Packing to further reduce IP headers with EoIP but wasn't that crazy.

I have a couple of Audience that we don't use since the cell antennas aren't that great. I've been using them to testing WW2 etc in V7. Basically bridging them without WDS/four-addresses I took as a Mikrotik puzzle. Since wireless bridging audience isn't a critical use case, was kinda looking more looking for thoughts on the problem since it was kinda curious what to could be done without WDS.

But the Dutch article/video was interesting (Google's English version). I'd have refresh my memory about MPLS etc. too – but will try at some point.

But yeah the MTU problem makes it more challenging, as the Dutch MPLS+VPLS PtP article points out:
MTU must be adjusted at MPLS / VPLS configuration to avoid fragmentation.
When the Mikrotik SXT encapsulates the Ethernet frame to send over VPLS pseudowire, it checks if the packet size + VPLS CW + MPLS tags exceed the MPLS MTU of the outgoing interface. If so, VPLS will fragment the frame. In this example, 1514 byte layer2 packets are forwarded over VPLS, router adds CW (4 bytes) and one MPLS tag (4 bytes). To avoid fragmentation, the MPLS MTU should be increased to 1522

It's the current WW2 limit of 1500 MTU throws a wrench in either EoIP or MPLS (or even VXLAN): the network-wide MTU still have to lower than 1500 (e.g. 1478 it seems with MPLS+VPLS).

I did report the MTU being limited to 1500 as a bug. Wi-Fi MTU is certainly complex, but I know it's always >1500 & so even with the saving from MPLS, it's still more than 1500 limit in WW2 today. The case is still open, so I've taken it that it's in queue to be fixed. As I said, this isn't critical for me, and imagine other bugs lurking WW2. Now WDS, that seem like a missing feature, so hard to know when that will come.

But MPLS was an idea I'd missed here, specifically VPLS I hadn't thought about.

Maybe some more protocols to explore, besides EoIP and VPLS

BCP, will split the packet over multiple PPTP channels to create a bigger MRRU to allow for the full MTU ? : https://wiki.mikrotik.com/wiki/Manual:B ... _bridging)
When bridging packets PPP tunnel need to pass packets with Layer-2 (MAC) header included , so default interface MTU (in case of pptp it is 1460) is not sufficient for this task. To ensure proper operation itbis suggested to override the value by specifying MRRU option in server settings to a higher value.

MRRU allows to enable multi-link support over single link, it divides the packet to multiple channels therefore increasing possible MTU and MRU (up to 65535 bytes)
.
VXLAN: yet another protocol ? https://help.mikrotik.com/docs/display/ROS/VXLAN (ROS 7.1)

I use VPLS and EoIP and BCP and VXLAN all the time. All are overcomplicated for this scenario and not suitable workarounds for that reason. We need four address mode support.

Don't disagree, but right now the bigger bug is MTU being limited to 1500 on the wifiwave2.

@mducharme, when you say "four address mode", to me that's just the 802.11 data structure used to carry the add'l MACs – how it should be used is a better question in V7. V6 used it a few different ways however... Are you advocating for "station pseudo-bridge", or standard WDS, or maybe HWMP+?

Personally I'd prefer Wi-Fi 6 support, which isn't possible on the Audience. Which is kind why I'd rather see Mikrotik spend some time to think about new/better/cleaner ways of wireless bridging until they come out with 802.11AX hardware...

WDS at the very least, if not station-bridge.

station-pseudobridge I don't believe uses four address mode at all. It only supports bridging one MAC and my understanding is that it is just simulated bridging.

Yup. I’m hopeful, something, will come soon. Not an expert on the driver/kernel stuff but imagine WDS is covered by Linux stuff - they’d may just need to add the UI. I’m guessing what ever bug is causing the MTU may be standing in the way.

i ask since personally , I’m not sure all the V6 options aren’t need - the mesh vs WDS, pseudo vs regular, etc seems like too many modes. I always have to go back to wiki/help every time to recall which mode does what ;)

Don't think you have a problem with these modes .... :-) (not wifiwave2)

"AP -bridge" (bridge function (4-address) can be disabled, WDS function is included), "bridge" is the level 3 single connection version of AP-bridge
"Station - bridge" the only real station setting. "Station" can be used to not request the bridge (4-address) function from the AP.

Normally that's all one needs. Bridge (4-address) function is great for PtP and PtMP wifi links between MT devices.

WDS is not needed for 4-address connections between MT.
WDS with "station-WDS" as WDS client, or "WDS slave" as WDS client+AP function.

Pseudobridge is a MAT (MAC address translation) L2.5 bridge. Has a mapping table for multiple IPv4 addresses for one receiving MAC (wifi is 3-address, MAT expands to multiple IPv4 clients)
(MT DHCP usually has problems with this). Is one-way for setting up connectios, because the table has to be built Not recommended. Is a typical function in non-MT "repeater" cases.

Waiting for 4-address bridge function in wifiwave2, or it is not suitable for PtP/PtMP.

WDS works with other vendors with 4 address mode though, if you make it an open AP without security. In some cases this can be a reasonable compromise even for PTP across vendors (ex. where you are encrypting everything over the link through some other means like IPsec anyway). It is the only way to get true bridging between MikroTik and non-MikroTik devices. I've used this where I have had to do a phased migration from third party radios to MikroTik. Obviously when WPA2 is involved WDS bridging only works between devices of the same vendor. station-bridge is preferable from MikroTik to MikroTik though, probably slightly more efficient than WDS.

I haven't seen it mentioned in the change logs, but I'm assuming we still don't have 4 address/bridging available in the Wave2 drivers?

4-address mode must be a very low priority.

Long enough that I don't even have the test setup anymore. ;)

My business partner took one as a travel router, and a customer has been borrowing one for months. The Audience is a nice device and the WifiWave2 has worked flawless as a single AP, which why I don't have them back ;). Have a few wAPac's but worthless for testing WW2. Been waiting for newer"ax" devices for a while...

But anyone know if the MTU issue been fixed? It was limited to 1500, when I last tested it.

If it's the only AP, it works great. It was night and day on the Audience compared with "stock" drivers. Suspect be same on the ax3's (which I'm waiting for)

Now I'm 100% sure you're not going to like the "CAPsMAN for everyone" way you configure WifiWave2 drivers....

Normis explained a while ago that ax devices can only run wifiwave2 "crapola" ... not supported by legacy driver at all.

So let's brace ourselves while waiting for @anav to axe that ax3 :wink:

Is the ax hardware getting some MT legacy driver options, sooner than the ac hardware?

Release notes 7.7rc5:
*) wifiwave2 - added option to set per-client vlan-id in access list (only supported on 802.11ax interfaces) (CLI only);

hi bpwl there are many CLI only wifiwave doo dahs noted on the 7.7 release.
Do you have clear way ahead for a standard setup of one hap ax3 using these things.....
I was hoping MT was going to make things clearer but it seems worse now LOL.

It actually be good to know if QuickSet does something reasonable on the ax3. There just aren't as many options in the WW2 drivers without the missing "4 address mode" (e.g. WDS, bridging modes, etc) ;).

+1
Please implement station-bridge/ap-bridge and WDS in wifiwave2, making sure it is inter-operable over the air with the older driver too (at least in plain 802.11 if nstreme/nv2 are too difficult with the new code base).
The fully transparent bridge mode (without ugly "MAC address NAT" hacks) is an important feature with many good uses, from extending home WiFi networks to WISP PtMP setups. While not a true WiFi standard, it is standard enough that I have sometimes used "static mesh WDS" for connecting UBNT M5 series stations to MT APs (802.11 only as the proprietary TDMA protocols are not compatible, but WPA2-PSK AES encryption works fine, and connected stations appear as bridge ports so all features of the new bridge implementation can be used). Actually, it would be nice if ordinary WiFi stations could appear as bridge ports as well - then you don't need a separate bridge implementation hidden inside the wireless driver in AP mode, just re-use the same existing fully-featured one that can do VLAN filtering, R/M/STP, bridge firewalling etc.

I've been waiting for this feature for a long time too. Perhaps at some point mikrotik staff could hint at whether this is on the roadmap at all? I understand it's difficult to commit to an implementation date, but if there is no intention of introducing this functionality to wifiwave2 it would be great to share this information with users.

I do hope that isn't the end of the story here. But "meshing" is the unique feature in the Audience... And yes it's poor choice today: Wave2, no mesh, OR use the "old" wireless package and have a mesh...
VXLAN: yet another protocol ? https://help.mikrotik.com/docs/display/ROS/VXLAN (ROS 7.1)
I do have a couple hAPax3 I have been testing, so tried the VXLAN approach. The hard limit of 1500 MTU is still present which is still my personal biggest grip here. So this any alternative approaches will result in fragmentation. I'd actually be fine with some tunnel over wi-fi — but I don't want MTU to get squashed by the 1500 MTU limit in wifiwave2.

Since I was also curious how well AX does in 2.4GHz, as these hAPax3 were my first AX devices. In theory it should perform a lot better with congestion than ac...so I created a PtMP link using the hAPax3's "wifi2" interface that carried a VXLAN tunnel over the 2.4Ghz AX interface.

Summary is a VXLAN does work. And, yes, it does get unnecessarily fragmented but "works" nonetheless. Basically you (from a winbox POV):
- take wifi2 out of bridge on both
- one becomes get set to "station", other remains "ap"
- set SSID "AX 2488 Mesh" on both (or whatever)
- assign 172.22.88.1/24 as IP for "wifi2" on ax3 "ap" (or whatever unique subnet you want)
- assigned 172.22.88.2/24 as IP for wifi2" on the "station" ax3
- create VXLAN interface using defaults on both
- hit "VTEP" button to link the VXLAN to the IP address of the far end Wi-Fi interface's IP (e.g. on AP, 192.22.88.2... on one/more stations, the VTEP address is 192.22.88.1)
- add VXLAN to bridge as a port (and set PVID if vlan-filtering=yes) on both

FWIW, ZeroTier also works to bridge a network over Wi-Fi PtP/PtMP here too. The key is the Wi-Fi interfaces have to have routable L3 addresses, just like for EoIP or VXLAN, for the tunnel endpoints.

Thanks for the writeup. I got things working between two Audiences for a customer, who wanted to take advantage of the greater bandwidth offered by the newer drivers.

It works. Thanks.
I have sucessfully briged two hAP AX3 routers to extend home network.

One remark is to check on brige ports and include VXLAN in LAN. This can save you a lot of time wondering why it doesn't work.

I had issues with FW rule "Drop All Not Coming From LAN" as connections were dropped.
- DHCP was not working on station wifi clients due to this.
- manual IP set was also not working.

Add me to the list as well of those who hope that 4-address comes back. I have a WISP with hundreds of Audiences in production that I cant take advantage of wifiwave2 on due to this. I will try the VXLAN workaround, but I will not accept this as a solution. Due to the limited MTU and the complexity added by using VXLAN, it will probably never see the field until this is resolved. This is making it very difficult to maintain Mikrotik as a primary vendor for Client-side WIFI.

It's actually the "wifi2" that need to go into the LAN interface-list (or tunnel subnet "172.22.88.0/24" needs to be allowed in the firewall) – that part may not have been listed :(.

But the VXLAN itself is bridged, so to the firewall the "inner" traffic comes from bridge/VLAN as the interface, not the VXLAN interface. But the "outer" VXLAN packets (with 172.22.88.0/24 address) come via wifi2 which should NOT be in the bridge (but does need to be allowed by firewall).

No, station can only communicate with single AP (and not directly with other stations, even if they all connect to same AP). However, this might work: station <-> AP <-> station ... Keep in mind, that from network infrastructure perspective AP doesn't have to be in some certain spot. E.g. in your case, AP can be device without wired connection. In your case it only matters where the L2 tunnel (whatever variety you're using) terminates, it has to terminate on devices which are connected to wired parts of network, in the topology mentioned at the beginning of this post this means the left and right station devices while device in the middle (AP) only serves as transport node (since 4-address mode is not available, you'll actually have two IP segments, AP In the middle being part of both and it will route between both stations).

That's what I was going to say. Both station use the "middle" as their VTEP address. VXLAN allows a one-to-many topology.

Thank you Mkx

it seems to work !

I try with 1 rb4011 (main router with dhcp server) and 3 hapac2 configured with vxlan and all ports bridge except wifi2 and dhcp clients on the bridge (no firewall, nothing else)

station1 (wired) vxlan 172.22.88.1 => receive ip from rb4011 (192.168.....) =>
AP (non wired) vxlan 172.22.88.2 => receive ip via station1 (192.168.....) =>
station2 (non wired) vxlan 172.22.88.3 => receive ip via AP ? (192.168....)

VTEP remote ip station1 = 172.22.88.2 and 172.22.88.3
VTEP remote ip station2 = 172.22.88.1
VTEP remote ip AP = 172.22.88.1

does that seem right to you?

Hello everyone

the configuration below works fine but I am experiencing issues with the DFS channel
with the public, the third radio only uses DFS channels. To mesh these 3 audiences, I use the third radio with the same frequency (of course), but I have an environment with radar and at least one audience changes frequency and loses connection with the others

I am trying to set up multiple channels in the third radio with the expectation that if there is a DFS radar all audiences try to connect in another frequency configuration respecting the order, but no, the audience chooses their own frequency and all audiences disconnect.

for now I change the third radio to a 2nd (5ghz) with only channel 5180 (no DFS) and it's ok, but I only have 2 channels (4 channels with third radio) so I lose half my speed.

is it possible to configure with vxlan the third radio with a 2nd backup radio when DFS cuts the first link (like a failover)?

Re: Using WifiWave2 to bridge two Audience wirelessly, thoughts? == 4-address mode

Thu Jul 20, 2023 5:26 pm

is it possible to configure with vxlan the third radio with a 2nd backup radio when DFS cuts the first link (like a failover)?
Sure, but not exactly "easy". VXLAN using Layer3 IP to make the tunnel – so the solutions are roughly the same as having a "dual WAN", except it's a "dual WLAN". So, essentially, more IP address/subnets, and importantly a check-gateway=ping on the "primary" wireless IP route is what's needed (or, for the adventurous, check-gateway=bfd perhaps). Let me think about this one. Maybe others have suggestion?

As I did not want to give up on radio, did it a bit differently, seems to work. The difference is in adding a virtual station / AP on both ends

router 1, connected to the internet:
- AP 2.4 GHz
- AP 5 GHz,
- virtual AP 5 - repeater, master AP5, not in bridge

router 2, remote site:
- AP 2.4 GHz
- Station 5 GHz - repeater
- Virtaul 5 GHz AP, master Station 5 GHz, connected to remote virtual AP 5, not in bridge

The rest of config is the same, adding vxlan interface and putting it into the bridge. That way I have both 2.4 and 5 GHz APs on both sides.

Yeah the approach depends on one be "ap" and one/more being "station" and none being in a bridge directly – but it doesn't matter if any are virtual wireless interface.
Mixing "ap" and "station" seems to be a feature of the wifiwave2 drivers – at least on ax2/ax3. Likely Audience, but didn't test mixing station and AP on same interface on that one.

I'm in the process of setting this up...

One question I have, should the neighbour-groups be shared between both Audiences?
What do I need to do to make this happen, CAPSMAN, neighbour discovery?

I'm finding that devices are becoming confused currently, causing noticeable disconnects when roaming.
This didn't happen with one Audience, the roaming worked seamlessly, as you would expect.

As a side note, seems station-bridge is compatible with Fritzboxes, I've been able to effortlessly setup a bridge between the Fritzbox (wireless) and Draytek (wired) router.

IDK, but that does not sound like a good idea. The station bridge is still a station, so it's not a "neighbour" (it's a "child") & BOTH bridging and neighbor-groups is relatively new features – combo'ing them seems like a bad idea...

I've got it working with two Audiences in bridge mode. The command line wasn't obvious. It's interface/wifiwave2>edit wifi3 > configuration.mode and then change the text and ctrl-o to save and close.

If you make changes to the wifi3 tab, it resets it to AP or Station, and you have to edit it again. Which is a bit maddening.

Consequence from this feature only available in CLI for now. Winbox doesn't know about it yet.
It will come.

It's live in 7.12rc2

It's in the GUI and works as expected, and I have seen not only a jump in performance, but range, while using WiFi 2 drivers.

The WiFi is also more stable at the edge of its range, unlike the old drivers.

Where is meshing at with the Audience running the wifiwave2 package?

Re: Using WifiWave2 to bridge two Audience wirelessly, thoughts? == 4-address mode

Sorry to bump-up the topic again, but on the other hand, it is in my opinion related. I successfuly ran vxlan based solution to bridge two ax2s, with 2.4 and 5GHz APs on both sides.

Recently, as 7.13 came out, providing station bridge mode (my understanding is, it is a so called 4-addess support), I have dissmantled the vxlan solution, trying to simplify it, using the station bridge mode on wlan1 5GHz radio for the repeater purposes.

I have tried the following scenarios:
  1. Setting up the wlan1 as an AP and additionaly creating new instance for the station bridge repeater purpose as a slave. Because there is no client at the time connected to the master AP on wlan1, it goes to "sleep". So first - can I prevent this? Second - it does not allow me to add the slave station bridge instance to the bridge.
  2. Reversed the scenario and used master as a station bridge for the repeater purposes, additionaly created a slave 5GHz instance for the AP purposes. But - I can't set frequencies (the tab is missing, probably taking over the master frequency), second - this 5GHz slave AP can't be added into the bridge either.
So - so far, the repeater mode works, but on the router2, there is only 2.4GHz AP (wlan2) and wlan1 serves only the purpose of repeater bridge station. Can it be somehow resolved, before reverting back to the vxlan solution, to allow me to have 2.4GHz + 5GHz APs on both sides?

Thanks,
/Petr

... Yes as with the legacy wlan driver, was also like that.

Not able to add this interface to the bridge ? Unexpected.

Using version 7.13.1, when I have added virtual 5GHz AP, it could not be added to the bridge. It also reset master station bridge to just station and disconnected from the main router.

After upgrade to latest beta 7.14beta4, it all seems to work. Will further watch it and if problems reappear, will revert back to vxlan based repeater solution.
