Wifi in Arch

[cosmarchy]

Hello all,

I've installed Arch on my Raspberry PI and I have a Edimax EW-7711uac USB wifi adaptor connected. At first I had problems with it not saving the profile after I did

wifi-menu -o

I can now get it to save the profile (by using a different adaptor) but after a

netctl start wireless-home

it still wont connect. I get an error message of

Job for netctl@wireless\x2dhome.service failed. See 'systemctl status netctl@wireless\x2dhome.service' and 'journalctl -xn' for details.

Examining these files:

[root@alarmpi netctl]# [root@alarmpi netctl]# journalctl -xn

and

[root@alarmpi netctl]# systemctl status netctl@wireless\x2dhome.service

It looks like some corruption / mis-configuration in wpa_supplicant?????? I didn't think you had to edit this file when using netctl, is that correct?

Can anyone tell me where I am going wrong?

Thanks

Edimax EW-7711uac, this uses wlan0, yes?
Make sure pkg wpa_actiond is installed, then-

Code: Select all

systemctl start netctl-auto@wlan0.service 
systemctl enable netctl-auto@wlan0.service

Hi, thanks for your reply. I tried your suggestion and this is the response I got:

I'm not 100% sure but this looks to me like like it's saying /etc/wpa_supplicant/wpa_supplicant.conf is corrupt on lines 5 & 8 but when I look in this conf file, lines 5 and 8 are part of the comments section at the beginning of the file.

Have any files been edited in Windows?
Maybe uninstall wpa_supplicant, delete file and install again.

In the end I started again from scratch. I believe I put everything back in and in the same order and this time it worked. Well, I say worked, I still had errors but it cleared up this one!!

Wifi is now connected and working; Arch linux seems quite a funny beast to get right with regards to wifi
