Wi-Fi 6 AX200 firmware issue

I have an issue with my PCI network card on Arch Linux. The card is TP-Link Archer T4E

I can't connect to my home 5GHz wifi. It works with other wifis on 2GHz.

The connection process is starting, takes a while, and breaks. Sometimes it connects, but the `arp` table is not complete and internet access is not working.

Here are the infos of the card and my os :

uname -u

Linux fgdou-fixe 6.8.2-arch2-1 #1 SMP PREEMPT_DYNAMIC Thu, 28 Mar 2024 17:06:35 +0000 x86_64 GNU/Linux

Do you know any other way ?

I tried to rollback to those firmwares :

  • iwlwifi-cc-a0-50.ucode.zst

  • iwlwifi-cc-a0-59.ucode.zst

  • iwlwifi-cc-a0-66.ucode.zst

  • iwlwifi-cc-a0-72.ucode.zst

  • iwlwifi-cc-a0-73.ucode.zst

  • iwlwifi-cc-a0-74.ucode.zst

  • iwlwifi-cc-a0-77.ucode.zst

And I tried adding those options to `/etc/modprobe.d/iwlwifi.conf`

options iwlwifi power_save=0
options iwlwifi uapsd_disable=1
options iwlwifi d0i3_disable=1
options iwlwifi 11n_disable=8
options iwlwifi bt_coex_active=0

Re: Wi-Fi 6 AX200 firmware issue

You associate w/ the AP effortlessly but then, exactly 10s later, might be good to know what's going on in the userspace during that time (and in general)
Please post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

Re: Wi-Fi 6 AX200 firmware issue

The intel AX200 is just not a well supported card. I have one too in the tuxedo nano i use, and with my ISP's router it works perfectly, stable with good speeds, but with the Unifi wireless acces point i have it keeps crashing and restarting on default settings.

What i did was change the settings on the Unifi AP, i think changing the channel width was what finally got it to stop crashing, but it's at around 180mb/s now, compared to the 500mb/s i can get on the ISP router.

Thing is, it's not a broken AP or anything - my phone and 2 laptops all work great on it with good speeds. there's just some oddity that crashes the AX200 when connected to that access point in my case.

I think you are right, there is nothing we can do about it, I guess. That's sad. I bought a TP-Link router to finally have a good Wi-Fi, and it doesn't work with my main PC.

Re: Wi-Fi 6 AX200 firmware issue

First of all stop dhcpcd, you're already using the NM internal dhcp client and they trip over each other, resp. both try to solicit a dhcp lease and up-until that point everything looks fine.
There's a good chance that your AP simply doesn't like the spam and ignores both because it considers this a pot. DOS attack or whatever.

If the issue remains, report back w/ a clean journal.

Yes, good call, thank you. I think I did try to enable / disable it in the past. But disabling it now, it doesn't solve the issue : https://0x0.st/X-us.txt

Re: Wi-Fi 6 AX200 firmware issue

Ok, same situation: effortless association and then stuck in dhcp.

1. idk what how or why a "cinnamon" process would call into wext, but it's probably a good idea to try this from something that's not cinnamon (basic openbx, icewm or so will do)

Apr 12 16:22:28 fgdou-fixe kernel: warning: `cinnamon' uses wireless extensions which will stop working for Wi-Fi 7 hardware; use nl80211

2. assuming it struggles w/ the particular dhcp request and since you've installed it anyway, you could use dhcpcd as NM dhcp client, https://wiki.archlinux.org/title/Networ … HCP_client (that's ok, just not running multiple dhcp clients)

3. reboot the router to make sure it's not still sulking because of the previous collisions (ie. flush its volatile memory wink

Interesting, changing the dhcp on NetworkManager doesn't change anything. However, when I start my computer without cinnamon and lightdm, I am able to connect to the 5ghz wifi with nmcli. Everything works as expected.
But, as soon as I launch lightdm and cinnmon, it stops working and goes in the loop again.

Re: Wi-Fi 6 AX200 firmware issue

I assume lightdm also doesn't matter?
=> https://github.com/linuxmint/cinnamon/issues

This is likely some network monitor or power management stuff, but I've no idea where to look for that.
You'll have to ask upstream
