Can you help me with any clues on the 5g configuration?
I was dealing with a very poor wifi performance on 5G (I don’t even care for 2.4 since it’s only used in my house for IoT stuff). After some experimentation, I finally managed to find good settings that deliver a good signal coverage, download/upload speed (almost the same I get via cable).
The problem now is related to stability. Connections work fine, but I noticed every time I’m in a meeting via Teams - for instance - suddenly connection drop, and I need to wait up to 10s, and it starts to communicate again. Then I decided to troubleshoot and ping both the DNS and Mikrotik. When the connection drops, I start losing packages between my computer and the router, making me believe the issue is Wifi instead of the internet.
Have any of you folks faced such an issue before and have any advice or idea?
XXXX stands for Ceee, eCee, eeCe or eeeC , this is a 80 MHz wide channel. MT uses the mid frequency of the C channel (other brands use the mid-freq of the wide channel, not MT)
With width XXXX the C channel position is not known in that wide channel, it can be any of the 4 possible positions.
The freq of channel 40 is 5200, 44 is 5240, 54 should not be used as it falls between the 20 MHz increments.
40/XXXX and 44/XXXX greatly overlap https://goughlui.com/2018/06/04/note-choosing-5ghz-wi-fi-channels-for-802-11ac-in-au/
add action=reject allow-signal-out-of-range=10s
Not sure if it acted here, but here one says that the once weak signal will be still considered as weak for 10sec, even if it is already strong (out-of-range) again, so it will be rejected.
Add “/system logging topics=wireless” to see what happens.
I believe my export have some garbage. I tried to implement CAPsMAN here and move forward without it. These frequencies in the export are related to the CAPsMAN.
Do you believe these inactive CAPsMAN configuration play any role impacting my Wifi connection?
I have removed all CAPsMAN settings, here is the export:

OK, will look again for possible “obvious” values in the config.
This is not fully predictable as the wifi RF environment plays a major, and it is difficult to account for all MT different devices and RouterOS versions.
-“RouterOS 7.1.1” is a potential problem. Many reports on this forum of people having to go back to 6.49.2
-“set [ find default-name=wlan2 ] band=5ghz-n/ac channel-width=20/40/80mhz-eCee country=no_country_set disabled=no
frequency=5765 frequency-mode=manual-txpower mode=ap-bridge ssid=AB-HOME5G-TOP wireless-protocol=802.11

—> 80 MHz is wide, but correctly set for “no-country”=FCC=US, country must be filled in, manual-txpower ???, SSID with non standard characters “-”
-“/caps-man manager set ca-certificate=auto certificate=auto enabled=yes” - could be disbled
" /interface detect-internet set internet-interface-list=WAN lan-interface-list=LAN wan-interface-list=WAN" - prefer not to detect but set manually, what is done correctly already

“/interface wireless cap set bridge=bridge caps-man-addresses=127.0.0.1 discovery-interfaces=bridge interfaces=wlan1,wlan2” - cleanup ?
I’ll try these fixes.
The frequency was set according to the scan I did here. There’s no other network under the same channel.
Maybe there is something related to the firmware version. It’s been annoying have so many disconnects all day.
