[SOLVED] Archer TXE72E networking adapter: WiFi broken/Bluetooth okay

Solution: The problem was that the card wasn't fully seated in the PCIE slot/making it fit into the bracket slot was unseating it slightly, and networkmanager wasn't enabled. I bent the bracket + enabled the network manager service (see last post) and it works now.

I recently installed a PCIE Archer TXE72E WiFi/Bluetooth adapter by TP Link (https://www.tp-link.com/us/home-network … er-txe72e/).

Bluetooth works, WiFi doesn't. I've looked through https://wiki.archlinux.org/title/Networ … n/Wireless and I can't figure out how to fix it.

I'd appreciate help. Thanks!

Things I've checked/tried

It seems like the driver isn't being loaded, but I can't figure out how to load it. I think it's an intel chip based on the advertising saying "The latest Intel® Wi-Fi 6E chipset’".

If it matters, I do have an ethernet cable plugged into the system as well.

Output of lspci -k: https://files.catbox.moe/dtsjf7.txt (no mention of a network controller or iwlwifi).
Output of ip link: https://files.catbox.moe/k0xr86.txt (no wireless network interfaces created).
Output of dmesg | grep firmware: https://files.catbox.moe/aasdrc.txt (no mention of iwlwifi)
Output of dmesg | grep iwlwifi: None
Output of lsmod: https://files.catbox.moe/ejy9kb.txt (I see iwlwifi, it is not used)

I've tried running modprobe iwlwifi, which ran succesfully and output nothing, and rebooting a few times, but still wifi doesn't work.

I've tried re-installing linux-firmware (pacman -S linux-firmware) and rebooting a few times - hasn't worked.

If it's not showing up in lspci it's not showing up to the OS. Make sure it's properly and correctly seated and in generally the correct port and that it is e.g. enabled in your UEFI.

Re: [SOLVED] Archer TXE72E networking adapter: WiFi broken/Bluetooth okay

Thanks! That was indeed a problem. It turns out getting the bracket secure unseats the card, like the card just isn't long enough. Bending the bracket fixes that problem.

Now I see the network interface in lspci, and a wlan0 interface. However, wifi doesn't work still.

The state of wlan0 is:

3: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN mode DEFAULT group default qlen 1000
    link/ether 74:13:ea:bf:f7:de brd ff:ff:ff:ff:ff:ff

And dmesg | grep iwlwifi output is:

The only thing that looks like an error is 'WRT: Invalid buffer destination', and searching that I see forum posts from ~2012, which don't seem relevant anymore.

What commands do you use to configure wlan0 and what are the outputs from those commands?

Re: [SOLVED] Archer TXE72E networking adapter: WiFi broken/Bluetooth okay

I used `ip link set wlan0 up`, it output nothing. I haven't done any other configuration

Re: [SOLVED] Archer TXE72E networking adapter: WiFi broken/Bluetooth okay

If you bring the interface down with `ip link set wlan0 down` does the output change to:

3: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,DOWN> mtu 1500 qdisc noqueue state DOWN mode DEFAULT group default qlen 1000

Then back to what you posted before after you run `ip link set wlan0 up` again?

Ah, I used `iw` to scan for networks, and they did show up. The problem was that I hadn't enabled network manager, so I didn't see UI options for wifi.

`sysetmcl enable NetworkManager.service` and `systemctl start NetworkManager.service` got them to show up.

It works now! I just needed to plug it in correctly, wow. Thanks for everyone's help.

Re: [SOLVED] Archer TXE72E networking adapter: WiFi broken/Bluetooth okay

I've updated https://wiki.archlinux.org/title/Networ … ver_status with info saying if lspci has no output, the card may not be plugged in properly.

This was my first wiki edit, so if the info would be better in a different place (or not there at all), let me know
