did you take this setting into account?

Kerbia

I can tell you what's happening next, if anything happens. They'll tell you that they didn't receive any of your Emails. At least that's the usual answer they give in the forums. And then sometimes they all of a sudden are able to send an answer to the not-received Emails. Devices are great if they'...

Kerbia

Thanks for your response. What's the most efficient and up-to-date way to realize this scenario? https://wiki.mikrotik.com/images/f/f3/Vlan.jpg I found this page in the wiki ( https://wiki.mikrotik.com/wiki/802.1q_Trunk_extension_over_Wireless_P2P_Link ) , but it seems inefficient to me, if you can ...

Kerbia

Hello, just a kinda quick and simple question: is the scenario mentioned in the link below possible with an SXTsq Lite2 ( License Level 3!!) device? https://wiki.mikrotik.com/wiki/Manual:Wireless_VLAN_Trunk Background information: I want a point-to-point link from my house to the house in our garden...

@Kerbia Would you please share your configration? What type of clients are disconnecting and what is theire average signal strenght while this happens? 6.43.13 - Access Point Settings I tried to do some finetuning for one Iphon XR that was basicly unusable. Still - the Group key exchange failures a...

Kerbia

use multiple ssids + vlans. the rest will just make your life harder, when stuff doesn't work on user side.

Kerbia

It's multiple devices from different manufacturers. Playstation4 Wireless Printer from HP Various different kind of Samsung Smartphones Iphone etc. Signal strenght across all devices is very good, since they're all located in the same small flat. Disconnect happens exactly when the exchange interval...

Kerbia

Okay, so with 6.43.8 it's still not fixed.

Group exchange timeouts happen exactly in the intervall that is set in the security profile. For me that's atm one hour.

Good job, Mikrotik. NOT!

Kerbia

@sjoukes would you be so kind and let me have a look at your "fixed" settings where the group exchange timeout doesn't happen any more? While running 6.42.9 I didn't have any issues the last months on a hap ac^2, while shit is driving my nuts on a cap ac. Both access points are connected ...

Kerbia

you need to have WPA2 w/ AES only in your security profiles and apple devices will work again. I have couple sites with "iphone problem" and some other sites that have apple products, but there is no problem, with the same hardware (wap or wap ac). The problem occurs randomly and present ...

Kerbia

Just experienced the same issue on 6.43.8 Hex Poe + ac AP. don't expect any help from support. i have had a lot of issues since i got some hap ac^2 and cap ac. support was either not responding or slow and asking dumb questions. my recommendation: run 6.42.9 bufix/longterm version. that one is runn...

Kerbia

6.42.7 runs quite fine - but webserver is broken there.

6.43.2 intense group key exchange problem as usual. it's 4 months since this issue has not been fixed. i just plugged in my mikrotik for a week of testing, not using them anywhere in any productive environment.

Kerbia

I have port flapping issues on hap ac². Anyone else?

Kerbia

Webserver Crashed
Telnet service crashed.

I confirm this.

Kerbia

6.42.6 --> say hello to group exchange timeouts again.

don't update from 6.42.5..

Kerbia

@Kerbia, I sent the suport.rif file together with the screenshot to support @mikrotik.com , let's see if they can receive it and reply. Advice: 1.) Read 2.) Post Not the other way around. Support didn't help at all. They're lying about not receiving Emails, but then answer to them after weeks of wa...

Kerbia

I don's see any such emails in our system, we usually respond in a few work days. Tell me the ticket number that was assigned and I will check where the email was lost. If this statement would have been true, how is it possible that I received a poor one line response today ( after 3.5 weeks - not ...

Kerbia

After two weeks still no new response from the "support".

Kerbia

Do you have the 6.42.4 running by now?

Kerbia

Last email to support was sent on June 16th. Again no response yet. Not even a "sorry, it might take a bit longer" notification. 6.42.4 tests are going on. First impression is that exchange key problems got less but wifi has ping spikes. I even tested that on a location, where there is no ...

Kerbia

Having fun in the last 6 minutes:

Kerbia

Small impression of the router log, while having a phone connected (or disconnected!).

Kerbia

Yeah, 6.41.4 runs stable for me. However, there is still the kinda weak throughput with this firmware. But at least it is quite stable. Ping: Lenovo Y510 Notebook --> Mikrotik hap ac ^2 (6.42.3) mikrotik_2.png With 6.41.4 Firmware I have no timeouts, and the ping is between <1 and 1 ms. Everything c...

Kerbia

After I changed the DHCP Lease Time and told them that this did not have any positive or negative effect at all, they wrote me a new Email few hours ago. They ask now if i collected some more information which would help them to understand the problem. Unfortunately I am not able to deliver more inf...

Kerbia

Thats's a message I received from support: i see that this device is passing VLANs through, what is the lease time on DHCP server? Does disconnects happen on intervals at half of lease time? Can You increase it for a test? My lease time was 3 days. I increased it to 5 days and didn't see any improve...

Kerbia

Hello, we replied to your ticket within three business days stating a question about whether the issue is still relevant in the latest RC version at the time, but never got back a reply from you. Since 6.42.2 there have been quite a few improvements for hAP ac^2 and we hope that your issue is fixed...

Kerbia

I answered two times on the ticket: - 1st time: 25.05.2018 at 11:54 Hello, it does not appear on 6.41.4 or 60.40.8. However, running the 60.40.8 isn't a real alternative to me, since the wireless performance of the device isn't as good as with the current or RC firmware. Regards - 2nd time: 28.05.20...

Kerbia

6 days ago they just asked me if i already tried out the RC versions, which was already mentioned in the ticket itself. since that time, i didn't get any response from the support. Hello, Thank you for writing to MikroTik Support. This is an automated reply. We will try to help you as soon as possib...

Kerbia

This log only shows one single minute.

Do you also face "disconnected, group key exchange timeout" or "disconnected, unicast key exchange timeout" issues?

If yes, you are not alone and should use the two existing threads for it.

Kerbia

Since i have these issues, i tried out every new RC version. It didn't help. Enabling/Disabling helps, but not always. When i couldn't reconnect at all any more i just switched between firmwares to get it going again. Support output file was sent to support last week. I'm waiting for a response. I a...

Kerbia

edit:// nvm.

Kerbia

Do you guys still have the described problem or did you manage to fix it finally?

Having the same issue with all up-to-date releases

Kerbia

I checked my other devices, I see the same problem on a hap lite, cap ac and the already mentioned hap ac^2.

The following firmwares were tested on all of those devices so far:
- 6.40.8
- 6.42.2
- 6.42.3

Kerbia

What firmware are you running tho?

Kerbia

I have the same problem. Under 6.42.2 or 6.43.X I sometimes can't even reconnect any more with any of the devices. Under Firmware 6.41.X or 6.40.8 I still get the timeouts, but at least I can reconnect. Submitted a file to the support. Gonna keep you updated. Would be cool to just use one thread for...

Kerbia

I dont understand. I have 4 hAP ac^2 (which runs on ARM) deployed and I haven't heard any complains from users. Could you be more specific what sort of crap there should be? I am aware of issues but there was nothing really serious what couldn't be fixed soon. there is a lot of threads about hap ac...

Kerbia

yes i do - i have a virtual AP on 2.4 ghz which is used for the guest network

Kerbia

Hey!
I made the changes you suggested. Exact 25 hours after I made the changes and restarted the router, all clients disconnect again and can't reconnect.

Any more ideas?

Kerbia

Hello, since ~1 week, i have wifi problems with my MT hap ac^2. All devices get irregular disconnects and no device is able to reconnect to the access point any more. Ethernet connection is still possible. I'm using Firware 6.42.2 - but I have the same issue with the latest RC version. The first tim...

Kerbia

After upgrading my hap ac^2 yesterday evening, I have issues connecting via wifi on an irregular basis across all my devices. I see the SSID but I can't connect to it. The log shows these kind of entries: disconnected, group key exchange timeout disconnected, unicast key exchange timeout Did anyone ...

Kerbia

Thanks for responding, Normis! I sent an e-mail to MikrtoTik Support and received reply saying that MikroTik did not have any problems with their hAP ac^2. After your Team Member had asked me to send more details with support file, I replied your Team with the support file and data. And there is no ...

Kerbia

https://twitter.com/mikrotik_com/status/988030137059958785 Doesn't look to me like they are really interested in the help of the community and customers to solve this whole problem fast. This is just my personal impression. Might be different for someone else. Sticking to Email communication makes i...

Kerbia

Already told them about this thread on twitter 4 days ago - posted a reminder few minutes ago as well....

4 days...

Kerbia

signal strength of the hap ac² is really awesome imo, and yeah i hope and expect higher transfer rates.

you will fall in love with mikrotik, but learning router os is tough at the beginning. but you grow after a while

.

Kerbia

Also, please provide more information, so others can actually help you.

What Mikrotik device are you using?
Which version of Router OS runs on it?
How does your network setup look like?

Kerbia

that's really interesting.

did you already do what they're asking for?
- I am not at my home for the next 7 days, so I can't test my hap ac² and cap ac devices yet. but definitly will do later.

Kerbia

Please MikroTik give us more information about the weak performance of hap ac² and cap ac. What further things can we do to support you fixing the issue? How have you been able to get the figures published on the product's page? What's the ETA to fix this huge problem? Please follow these threads: h...

Kerbia

i confirm the weak performance at hap ac and cap ac devices. too bad i didn't read the forums yet.

as i said earlier in a different thread: the hardware specs are part of my wet dreams. they're exactly what i waited for. i really hope this gets fixed soon.

Kerbia

I didn't see this thread before and was just hungry for the hap ac² and the cap ac by looking at the specs. they arrived yesterday. for me the signal strength improved a bit on both devices. however, i confirm from my side that the throughput is much slower. i am not using yet the RC firmware. i hav...

Kerbia

I'm glad you like it! Will you use the default case, or the square case? So far i love the look of the square case more than the round one. However i can't seem to replace the case with square one. Scared i might break of a pin and then I have to pay for it haha. It took me around one hour to remov...

Kerbia

oh dang!

i was also just looking at the specs page.

it's running fine with my switch for ~24 hours now.

thanks for your help, guys!

Kerbia

ah!

i really needed a lot of power, so much that i was afraid to breaking it.

however it's working fine now and i can enjoy mikrotik device no. 5 in my home

thanks!

Kerbia

Hey, i just got the new Mikrotik CAP ac, but i fail to switch cases and to unmount the metal ring on it's back. Since i don't want to use raw power, I am asking you guys: What's the trick about disamble the device? Picture: http://lanmarket.ua/upload/resize_cache/iblock/db7/1000_1000_1cb183357d6c369...

Kerbia

Hello, i already have a Mikrotik 260 GSP Switch (https://mikrotik.com/product/RB260GSP) and I currently think about buying a new access point.

Kerbia

Thank you so much guys!

I really appreciate your help!

Kerbia

You probably want two rules. One in forward chain to prevent access to other interfaces. And second in input chain, to prevent access to router itself (services running on it). From IP perspective, bridge is just one interface, no matter how many ports it has. So yes, you select it as input interfa...

Kerbia

Hello, i have one short question referring to the firewall rules and securing my Mikrotik router: I created one bridge (bridge A), which includes vlan10 and ether2. I want to prohibit any traffic or access from this bridge (including all of its interfaces) to the rest of my network, because it will ...

Kerbia

Thanks for all your responses. They help me a lot. Any band requirements? DFS support? Etc.? 2.4 Ghz should be enough. The main living area is on a different floor of the house. There I have a dualband ap. hap lite have a similar performance to another single core mipsbe mikrotik devices, you dont w...

Kerbia

The AP is supposed to extend my existing network (including vlans) on a new floor of my house. There will be 4 different SSID's belonging to different vlans, which have no access to each other. All are connected by one trunk port to the rest of the network. Regarding data, the AP will mainly be used...

Kerbia

Hey, I'm looking for a new access point and am interested in the Mikrotik hap lite. I know that this is a low end device, but it may be sufficient, since it is just for my mom's house.

Hello, last week I got a MikroTik 750gr3 and I'm currently using it to separate three networks from each other which share one internet connection.
