Atheros Wifi - No Networks Detected

[jonathand]

Hi there,

I only use wifi occasionally on my Mint 15 desktop, and noticed the other day that it no longer detected any networks in range. This had been working fine in the past. wlan0 appears in the ifconfig, and also disappears when I disable wireless, so I know the hardware is detected ok.

Code: Select all

wlan0     Link encap:Ethernet  HWaddr 00:12:bf:6b:e0:1e  
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

It also shows up fine in lspci:

Code: Select all

-PCI Devices-
Ethernet controller		: Atheros Communications Inc. AR5212/AR5213 Wireless Network Adapter (rev 01)

No results appear in the network manager in Mate, similarly a manual scan shows no results:

Code: Select all

sudo iwlist wlan0 scan
wlan0     No scan results

Does anyone have any ideas as to what might be causing this?

thanks, Jonathan
