F**G WiFi6 from C52iG-5HaxD2HaxD

CrazYViruS · April 10, 2025, 7:36pm

Good day to you all !
I have a problem that lasts since the purchase of C52iG-5HaxD2HaxD, which is more than 1 year !
It all started with the fact that WiFi 6 on RouterOS version above ~7. 15+ works unstable - at random times can happen a complete disconnect
I would have stayed on the factory version of RouterOS but there is a very low speed Wifi ~200mbs
I made a ticket - SUP- 164448 and after ~month of communication with the support team and searching forums I came to the conclusion that this is the problem of my wifi card in my laptop - Intel ax211 and I forced in the properties of my card to use only Wifi AC

. Time passed - new hardware appeared - with Intel BE201 and I also started to get the same problems.

I get disconnections with Windows Eventid errors - 7021, 6062
And in Mikrotik - “disconnected, connection lost, signal strength”

I’ve been using Mikrotik products for years, my IT infrastructure is built on CHR in offices configured CapsMan - but I can’t beat this crap.

I don’t want to lower frequencies below 80 I don’t want to switch to AC, that’s not why I bought this device - although if you tell me that the situation is not fixable and it’s a hardware problem - I’ll go and buy just an Asus…

Well, IMHO the Intel BE/AX Series is total garbage. I got an BE200 ever since it was released and its been a terrible experience.
There’s A LOT of people on the intel forums with issues with those cards.

Last good one in my opinion is the AC9260.

Well now the normal tasks to do:

Update to the latest WiFi Driver
Update to the latest (7.18.2) RouterOS
Create a Windows Wi-Fi Report
should look something like the attachment.

Other than that, cleanup your config on the Wi-Fi interfaces. Keep it simple.
You can try capsman. Some people once mentioned that it seems like us who have no issues all use capsman.
Only one person i know of who tested it so far but it sadly didnt change anything.
You can set up a config + provisioning rule and under “Radio” you can click provision to apply a capsman config on the local radios.

I’m using Intel AX and BE Wi-Fi Cards without issues using an AX3 and AX2 Combo with Capsman + FT, but because those cards have a sucky Frequency Range I must stay on low 5ghz channels.

EDIT: its a BE200.
I also got an AX210 and got the numbers mixed up woops. already changed in the text

i have ax210 nic and ac9260 nic, had to return to 7.14.3 (i dont use capsman)

CrazYViruS · April 10, 2025, 9:13pm

ok intel is bad but it’s 80% of the market.
From mid-range workstations like HP ProBook G10 with ax211, to premium segment like Asus Zenbook Duo with BE201 and what is the time difference between them by release date for example ?
AX211 = Q3’21
BE201 = Q2’24
A few years …
If the problem is only with Mikrotik (which is the most evidence but I don’t claim) then it is a Mikrotik problem

If the problem is general (then it is strange why Intel continues to release such a poor quality product)
Then a standard like IEEE 802.11ax - Dead ?
Otherwise I can’t find any explanation how the rest of the world can safely use AX when it can randomly stop working.

I would like to see Mikrotik’s official position on this - I think it’s time to clarify the situation and put some dots on it
