[SOLVED] wireless cofiguration issues; initramfs; 8192cu-dkms

Hi,

I have booted the Arch Linux installation medium. I want to have a stable wireless connection, but I can't load the correct drivers for my usb device. Here are the relevant outputs.

dmesg | grep usbcore 
[    3.442336] usbcore: registered new interface driver usbfs
[    3.442341] usbcore: registered new interface driver hub
[    3.442353] usbcore: registered new device driver usb
[    4.224128] usbcore: registered new interface driver usbhid
[   43.985146] usbcore: registered new interface driver rtl8192cu
[   44.345139] usbcore: registered new interface driver rtl8xxxu

dmesg | grep rtl8192cu
[   42.979358] rtl8192cu: Chip version 0x10
[   43.012574] rtl8192cu: Board Type 0
[   43.012267] rtl8192cu: Loading firmware rtlwifi/rtl8192cufw_TMSC.bin
[   43.985146] usbcore: registered new interface driver rtl8192cu
[   44.881948] rtl8192cu: wlp0s20f0u2: renamed from wlan0
[ 2181.576341] rtl8192cu: MAC auto ON okay!
[ 2181.586909] rtl8192cu: Tx queue select: 0x05

Since there's Loading and NOT loaded in the second output, I thought I'd have to disable rtl8xxxu to solve this.

echo blacklist rtl8xxxu >> /etc/modprobe.d/modprobe.conf

Then I added the path to modprobe.conf at the FILES section at /etc/mkinitcpio.conf and rebuilt initramfs, which printed this.

mkinitcpio -p linux

==> Building image from preset: /etc/mkinitcpio.d/linux.preset: 'default'
   -> -k /boot/vmlinuz-linux -c /etc/mkinitcpio.conf -g /boot/initramfs-linux.img
==> ERROR: specified kernel image does not exist: `/boot/vmlinuz-linux'
==> Building image from preset: /etc/mkinitcpio.d/linux.preset: 'fallback'
   -> -k /boot/vmlinuz-linux -c /etc/mkinitcpio.conf -g /boot/initramfs-linux-fallback.img -S autodetect
==> ERROR: specified kernel image does not exist: `/boot/vmlinuz-linux'

These are the only things I did until now and I don't know how to proceed from here. I also wonder how to get the 8192cu-dkms package from the AUR, that is recommended, if rtl8192cu does fail, when I cannot access the Internet on the desktop I'm trying to install Arch.

Re: [SOLVED] wireless cofiguration issues; initramfs; 8192cu-dkms

If I understood correctly, that you're trying to get wifi to work for the arch installation media, then blacklisting modules and rebuilding initramfs shouldn't make any difference.
If you want to disable the rtl8xxxu module for installation, you can simply unload the module with 'modprobe -r'.

I don't see any errors in your dmesg output, and would imagine your wifi should be working. Did you actually try connecting to wireless network with e.g. wifi-menu?

If you want to use 8192cu-dkms from AUR during installation, you should be able to build it on the install media as usual, as long as base-devel is present on the arch install media.

EDIT. Also, welcome to forums :)

No I didn't. . . I thought that there had to be an error, because the output didn't match the one of the wiki.
When I tried with wpa_cli, it worked.

Thank you
