Wi-Fi 6 AX200 keeps disconnecting after X hours

H

Hi!

I changed a mt7922 (that was slow, but never disconnected) for an AX200 wifi.
Now the AX200 seems to disconnect every X hours.. maybe 10 hours? 12 hours? something like that. It works, its running under wifibox, its fast at 10mb/s on 2.5ghz, and no special driver or kmod was installed.

My problem is with these disconnects every 10 or so hours... all my terminals get disconnected.. its annoying... plus i dont know if its a hardware issue.

Am i missing some kmod for this wifi chip ?

Or some other suggestion ?
 
Mine will drop randomly as well. Sometimes it works great for a bit (getting 300Mbs down), then it just drops. This does not happen on the same laptop w/Linux (multiple distros including Qubes). I am on 14.3-p2. Maybe this is something that will be fixed as they continue on their wifi improvements? I have not submitted any ticket yet, not sure if I should yet.

My logs show:

I am curious why you guys are using Wifibox for a supported chipset? AX200 and 201

Can't you use the iwl driver?


Do you have any AX200 card details to offer? Model? Brand Laptop?

I bought some random AX200/AX201 modules that I need to test. One was Bigfoot Networks.

I really have been avoiding Wifibox as I don't care for Alpine Linux for this type application.
OpenWRT is my preferred target for wireless virtualization. They have the best wireless support.

I would like to experience that.
 
What about channels? Have you experimented with different frequencies?
I wonder about 2.4GHZ versus 5GHZ use. 5GHZ brings DFS channels over channel 100. I could see that being more problematic.
Stay at channel 36-68 range.

Have you experimented with any VHT settings on your base station?

I have not done that yet since it works fine in other operating systems, but it is a good suggestion. It could also be something where FreeBSD is unhappy with something the base station (or other machine) is doing. 15 will be released soon, and I may just wait and see with 15. If it still happens with 15 I will definitely be troubleshooting more. It is taking every fiber in my body not to just backup this machine and try 15 but I will wait a bit :)

I bought this specific AX210 card and it worked great on 14.3-R-p2: https://www.amazon.com/dp/B0D2NV2RDH (reached WAN cap around 90Mb/s vs 20Mb/s on AC 9560)

I didn't pay much attention to the Linux install for wifibox, but I think it would be interesting to see FreeBSD working with OpenWRT to ship wifibox images! I use snapshots on my router and it'd be a cool pair to have it match on my laptop :p
 
Improve your settings, plus narrow down the BSSID and channels it runs on.

When that happens, it means your setup is not set up good enough, barely enough to work, so it works by chance. When you learn more and improve your settings, it will work more reliably.

This may sound meaningless, but it's not. When you learn how to improve your wpa_suppliant and rc.conf settings, it will work more reliably. When you do that, and it works better, you'll understand.
