USB Wifi Adapter Not Turned on

yayo_dinero · 2024-12-13 18:20:12

(This is all from within arch linux installation, no access to ethernet)

When I do `lsusb` I see my usb adapter `bus 001 device 002: id Realtek Semiconductor Corp. RTL8191SU.11n WLAN Adapter`. I can unplug it, run it again and see it omitted from the list. `ip link` shows me Wlan0, enp2s0, and lo, the first 2 are DOWN, and setting either to UP does not work. I am using the usb adapter bc wifi card is broken on motherboard. in `iwctl`, device list returns empty

Driver is updated as well

You're working through the nework configuration page of the wiki, right?

1. What kernel driver is in use?
2. What kernel module is in use?
3. What command are you using to bring the interface up?
a. What message is returned after running that command?

Cheers,

1. and 2. its a freashly installed arch iso
3. iwctl device list
a.returns nothing
3.lsusb
a.returns list of connected usb devices/ peripherals, including the usb wifi adapter dongle
With this information I know that we are detecting the dongle, but failing to be able to use it to connect to the wifi

Sorry, I missed that this was a brand-new installation and you're still running off the iso.

I've never used wireless from the iso, but I think that even if you're using the iso you'll need to have the kernel module loaded (1), (2). (Could be wrong about this.)

I don't think...

iwctl device list

... will bring the interface up. This is used to connect to a wireless device once the interface is already up.

Try

# ip link set interface up

... where interface is the name of your wireless interface, e.g., wlan0.

Cheers,

Got some outputs from dmesg that might be of more help than what I can do

rootearchiso ~ # dmesg | grep wlan0

I've attempted to set the state to UP with

ip link set wlan0 up

already, but it persists in the DOWN state, i've even tried to set the state to DOWN, then back to UP

1. https://wiki.archlinux.org/title/Tethering will probably allow you to
a) install the system
b) don't paraphrase, https://bbs.archlinux.org/viewtopic.php?id=57855 and post the actual outputs of ip, iwctl, lsusb, etc.

2. You say the onboard NIC is "broken", does it still show up in lspci/lsusb? Ie. are we sure wlan0 is actually the RTL8191SU dongle?

3. unplug the dongle, run "dmesg -W", plug the dongle, post the entire output generated by that (you can "dmesg -W | tee /tmp/dmesg.tail" and then "cat /tmp/dmesg.tail | curl -F 'file=@-' 0x0.st")

I know the onboard NIC isn't being recognized for wlan0 because when I unplug the dongle and rerun

ip a

wlan0 gets removed from the output

Im going to assume you meant to rerun the command, the first instance of "dmesg -W" is with the dongle unplugged and the second is with the dongle plugged back in. Same output for both cases, exited wtih "crtl + c"

Yes, and the idea is to make your life easier and get us more accurate information by using your phone as network device.

The plan was to run "dmesg -W" *while* plugging the dongle, not before and after - that's pointless.

Unfamiliar with the "dmesg" command
