[SOLVED] Wifi card is not being detected after update

I use TP-Link Archer T2U PLUS which uses the driver rtl8821au, i downloaded that driver from AUR and everything was working fine but 2 day ago i update my system andi stopped detecting that usb wifi adapter.
when i run nmcli it shows

wlan1: disconnected
        "TP-Link Archer T2U PLUS"
        wifi (rtl88XXau), 3E:50:48:18:E9:18, hw, mtu 2312

Re: [SOLVED] Wifi card is not being detected after update

Did that module build against the new kernel?

Re: [SOLVED] Wifi card is not being detected after update

Same issue here. After I updated my system yesterday, today my wifi card is undetected. The kernel module comes with the kernel itself.

EDIT: Downgrading the kernel to 6.8.7.arch1-2 did not help.

Don't grep, also your situation (w/ an in-tree driver fro a different chip) is likely different from the OPs

Re: [SOLVED] Wifi card is not being detected after update

Same thing here, with TP-Link Archer T2U PLUS. Stopped working after kernel upgrade.

SOLVED rebuilding the driver. Using this one.
