Nmcli "Qualcomm Atheros AR242x / AR542x"

Rocky Linux Help & Support

Hello,

when i call “nmcli device wifi list“ in a shell then i have in the wlp20s0 device:

wifi (ath5k), 00:22:5F:2C:E3:84, plugin missing, hw, mtu 1500

what plugin is missing? and what can I call in bash to scan available wireless networks close by?

and in “nmcli device” is the wlp20s0 device listed as STATE “unmanaged“

2

You can use:

iw dev wlp20s0 scan
3

that works not

$ sudo iw dev wlp20s0 scan

command failed: Network is down (-100)

and without sudo i (the user) have no permission [ Operation not permitted (-1) ].

What permissions are needed?

4

So you need to use sudo or run it as root user. It works on my system. But if your network is down, would suggest your wireless card isn’t working.

5

Could be you need ath5k module installing: Atheros support - #5 by toracat you can install it from elrepo. That example is for Rocky 8, but there is elrepo for EL9 and EL10 too.

6

i have installed actual kmod-ath5k. how can i scan for wireless networks? should “sudo iw dev wlp20s0 scan“ works?

The command “nmcli device wifi list ifname wlp20s0” reports

Error: Device 'wlp20s0' was not recognized as a Wi-Fi device, check NetworkManager Wi-Fi plugin.

“sudo lspci -s 14:00.0 -vv“ puts

out.

and “sudo iwlist wlp20s0 scanning“ outputs “wlp20s0 Interface doesn’t support scanning : Network is down“(on nonexistent devices the output is only “wlp20s0 Interface doesn’t support scanning.“)

Has the wireless driver support for “Qualcomm Atheros AR242x / AR542x“? probably new version of the driver is the problem.

I have a ICH8M Chipset and a Core 2 Duo CPU.

It is old hardware (from year 2007).

Hmpf ok, in 6.15.8-1.el8.elrepo.x86_64 works it like a charm since installing kmod-ath5k package.
