r00t

It's the same problem with Mikrotik over and over again. Nothing changed. You just don't know what is coming and when any new products will be released. No roadmaps, no planned products... and when some future product is announced, you don't get any date when it will be available (where's Terragraph...

Based on the above wine findings, I have tried to do the same on windows and it sort-of works, but it's not as good. I have injected DLL into winbox process that replaces GetSysColor API and instead of returning default windows colors, it returns colors from wine dark theme. This seems to be OK for ...

r00t

If Mikrotik had radios with multiple GigE ports, 2.5GbE or SFP+ slot, then it would be possible to really use entire 802.11ad channel. But with just single GbE it's a waste of channel bandwidth. So far 60GHz interference is not a big problem, but for how long? What will happen when Terragraph is wid...

r00t

Yeah, seriously this is LAST thing Mikrotik should be working on at the moment.
Just look around, there are serious bugs, memory leaks, ROS 7 issues, new wireless drivers problems...

r00t

RATE SELECT is specific pin of the SFP slot interface that can be used to change operating rate of the SFP module.
Low/High are actual voltage levels Mikrotik sets this pin to.
If it actually does anything and what it does depends on the specific SFP.
So check your SFP module specification...

r00t

I think "stable" should not be used in any release name, because of the confusion between "stability of the system" and "stability of the version". This is a good point. Maybe "Testing/Preview" (currently beta) -> "Release candidate" (for a week) ->...

r00t

I think main problem is branch naming Mikrotik is using. Anyone who doesn't know how things go with Mikrotik expect beta to be something that's like 90% stable and in most cases can be used to get cool new features without risking much. That's how it usually is when it comes to testing beta releases...

r00t

60GHz radios with SFP slots - this should have happened long time ago, even if it's just SFP and not SFP+. Running fiber is cheaper then ever before and solves EMI issues. WIFI6 - Mikrotik is late to the game and competition is never sleeping And in general anything that doesn't have flapping ports ...

The app doesn't stay connected to the router when you don't use it This is rather annoying, as you can't just use the app to monitor router for a longer time.

r00t

Best is to export all router configuration to a file and inspect it.

r00t

no, level 3 license only limits number of clients that can connect to the AP (ie. you can use bridge and not create AP for multiple clients). There is no difference in power limit or anything else. Your problem is probably too long distance for small antennas, inaccurate pointing or using channel wi...

The vendor class matcher that allows you to use specific 1-address addresslist for specific device class is probably most elegant solution that doesn't require mangling of all traffic.

Maybe you can use vendor class matcher? see https://wiki.mikrotik.com/wiki/Manual:I ... or_Classes

All 60GHz stuff mikrotik released so far is compatible and you can connect them together as you like.

Best way is to have both broken and working board on you desk at the same time, so you can measure on both and see what's working and what's not, comparing voltages at the various ICs. Then check all the voltages on capacitors. If one is missing, try to trace it on a PCB... if the trace is broken, y...

Actually, the wifiwave2 contains spectral scan kernel module - it's just not used for anything (yet?). But main limitation is the version of the radio chipset, AFAIK you have to pay more for advanced version that supports features like spectral scan, phase constellation view and TDMA/GPS timesync an...

r00t

I really hope will will see new beta with some fixes sooner than later... there's just so many bugs that make beta3 really hard to use, even for testing.

r00t

According to this block diagram it's single dual-band AC radio: https://i.mt.lv/cdn/product_files/Metal_52_ac_190358.png For comparison, here is block diagram for wAP AC (which have very similar HW compared to Metal) and you can clearly see dual radios: https://i.mt.lv/cdn/product_files/RBwAPG-5HacT...

r00t

Metal 52ac does have ac radio so it doesn't support spectrum scan.

r00t

On 802.11n radios, nstreme seems to be best for p2p, high throughput and low latency. As long as channel is clean and without interference. "lost connection, not polled for too long" means you have some interference on the channel and this really causes problems for nstreme. nv2 is more ro...

r00t

Yeah, this will not work. What will happen is one of the radios will be transmitting while other one is receiving. They will probably survive this, but there is no amount of filtering on normal boards that can reject another transmitter on nearby frequency. To combine multiple radios like this, you ...

Quectel is really PITA to work with. When I asked for firmware about a year ago, they told me to sign an NDA and mail it to them, otherwise they will give me nothing. Awesome...

r00t

On bridge, set STP protocol to none.
Also disable auto time zone and cloud time sync and internet detect, as these are other sources of unwanted traffic.

r00t

yes and best would be to use different polarization for each chain
if you have two antennas on both AP and client, simply rotate one 90 degrees to get different polarization.

r00t

I really hope there will be new v7 beta released soon (say in ~1 month) that fixes all these small bugs... it would be rather bad having to wait another 6 months for next version.
Right now this beta is too broken to be even tested properly...

r00t

wow, these are some really nice cards, for $17 this is real bargain!
Btw I just checked the routeros-x86-6.48.npk and it does have kernel modules for qca9984_pci.ko so not sure why it's not working. Maybe it wants different PCI ID? I guess only Mikrotik support will know what's going on...

pe1chl: Completely agree. At minimum, there should be a first paragraph on every page listing versions of ROS each page is relevant to. With big differences between 6.x and 7.x it's quite important to know. But also for features added to 6.x there should always be note of minimum ROS version, differ...

Yes, this is very annoying. Many notebooks have 802.11ac card that have only one chain. I actually replaced some NB cards to rather have two chains in 802.11n as that results in better signal and speeds in real world use than just single 802.11ac chain. Only recent notebook models with wave2 (or eve...

So this means only difference is that with native ROS license you can use wireless package otherwise it's same as CHR ?
I can confirm routeros-7.1beta3.npk package contains all normal wireless drivers, thankfully they are still present.

I'm just trying to brainstorm some ways to get it running. Yes, I have analyzed the package quite a lot, so while I can't be sure about used compiler options, I can see some details that may not be normally visible, like that debug info.

r00t

You can't modify packages, they are digitally signed and will not install if you change them in any way. But I agree it's clearly possible to make much smaller new wifi package. Also the RAM requirement can be lowered by using smaller buffers. The default sizes are optimized to get absolute maximum ...

You can unpack the wave2 wifi package with 7zip to see supported Qualcomm chipsets: IPQ4019 IPQ6018 IPQ8074 QCA9888 QCA9984 Now all the IPQ are integrated CPU with radio, so not what you want. So only QCA9888 QCA9984 are valid choices you should look for. This still doesn't guarantee you that any PC...

r00t

Stable has usage about 60Mb and this version is just raising up with no limits.

That looks like a memory leak. When it gets really high, make supout file and send it to the support. They should be able to find the culprit and fix it.

r00t

Reason is probably FCC or other similar regulator spotted "antenna gain" to be adjustable in one of the Mikrotik boxes with internal antennas and went full "YOU CAN'T LET USERS DO THAT!!!" and so Mikrotik removed/hidden it from GUI. I'm fine with that, as long as there is new fea...

Altering "All rates fixed" power level is the wrong way to do this. That's why there was "Card rates" option instead, but that stopped working with 802.11ac hardware. Why is "All rates fixed" bad? Let me explain: 802.11 uses various modulations, from classic BPSK/QPSK t...

i've been asking multiple times about Spectral scan, i want that features to be implemented on 5 mhz

Spectral scan is function of wireless radio chip. Mikrotik uses the cheapest versions of the chip that simply can't do it, no amount of software can fix that.

r00t

Looks like most 802.11ac products will never be able to run this new wireless package. Sad. I think it might be possible to port it to different architecture than ARM, but memory and especially flash requirements are most limiting. Getting it to work with 128MB RAM might be doable after some optimiz...

Beamforming is done by changing phase of the transmitted signal going into multiple antennas. That way it's possible to make all the transmitted copies of signal add exactly at the spot where client is receiving. This technology itself is antenna type agnostic.

Yes, it's not intuitive at all since Mikrotik decided to use same version numbering for routerboot and ROS. Before that, routerboot had it's own version number so it was easy to see if something changed or not and if it's really worth updating it. But now they keep version numbers in sync with ROS, ...

r00t

While other vendors are adding 802.11ax and more chains, MIkrotik is proudly presenting AP with less chains that's not even wave2 compatible in 2020,
with added bonus of having same naming as original, so you will never know what you may get from the distributor.

great job, well done.

r00t

Yes. Don't block the release just because one platform can't boot. It's still in BETA stage so such things can be expected to happen. Release it so new features can be tested and debugged while you are working on the TILE to boot again.

r00t

Test the PCB pads with multimeter in continuity/resistance mode. They will be wired in pairs and one pair will be ground (the button pulls the GPIO to the ground).
On your photo pad 1 is very likely GPIO pin as I can see filtering capacitor on it. So my guess is switch connect 1,2 (gpio) to 3,4 (gnd).

r00t

Re-using the name and model number when the hardware is so completely different is also not great. Now I have no idea if I order from a distributor if I get the old or new model, which is important if I want 3 chain 5 GHz, or want to run OpenWRT (the new model is likely unsupported for now). Exactl...

That's just WIFI scanner, not spectrum analyzer. It can only see WIFI signals that are supported by your wlan card.
Spectrum analyzer can see interference like microwave ovens, alarms, Bluetooth and other devices that coexist with WIFI in ISM band.

See this topic: https://forum.mikrotik.com/viewtopic.php?f=7&t=167044 In shot, there is no spectral scan supported on all newer Mikrotik products, so you have to use either old Mikrotik 802.11n box or Ubiquity hw for the job. Other options are also available, but far too expensive (RF spectrum a...
