A while ago the WiFi on my Acer Aspire 3680 just stopped working. The switch is on and it can see my network, but it will not connect. It has an Atheros AR2413 802.11bg NIC.
rfkill shows there are no soft blocks in place.
sudo rfkill list all 0: acer-wireless: Wireless LAN Soft blocked: no Hard blocked: no 1: phy0: Wireless LAN Soft blocked: no Hard blocked: no
Here is what
