I'm having a recurrent issue with my Arch Linux installation: wireless will work for a few minutes and then randomly die. When I try to restart it through wifi-menu I am informed there aren't any networks.

 > sudo wifi-menu
:: Scanning for networks                                                [FAILED] 
 > No networks found

Running netcfg directly, I recive:

sudo netcfg wlan0-2WIRE555
:: wlan0-2WIRE555 up                  [ BUSY ] Successfully initialized wpa_supplicant
Could not set interface wlan0 flags (UP): Connection timed out
nl80211: Could not set interface 'wlan0' UP
Could not set interface wlan0 flags (UP): Connection timed out
WEXT: Could not set interface 'wlan0' UP
wlan0: Failed to initialize driver interface
> wpa_supplicant did not start, possible configuration error

The output of lspci is:

Every time this happens, I have to restart in order to get internet working. Is there some systemd command I can use to restart it manually? Is this an issue I can resolve permanently?

  • Give us a little more info. Give us the `lspci` output for the wireless interface itself. `lspci` says this about my arch wireless interface: "05:00.0 Ethernet controller: Atheros Communications Inc. AR5212/AR5213 Wireless Network Adapter (rev 01)" –  Apr 09 '13 at 01:18

I don't have a Centrino chipset machine, but I do run Arch on my laptop, and I've experimented with a lot of wireless cards and drivers.

A little googling around shows me this:

It also looks like some laptops have an external wireless switch. Ensure it's "on".
