I'm using Ubuntu 10.10 on an hp dv4 and my wifi was working just fine(except the wifi led blinking) till yesterday. Now when I touch the wifi button it just won't switch ON!!! :o I didn't make any changes yesterday but updated my system today.
I have no idea what happened. Any clue???
I ran the command
sudo lshw and got its output as:
*-network DISABLED description: Wireless interface product: AR9285 Wireless Network Adapter (PCI-Express) vendor: Atheros Communications Inc. physical id: 0 bus info: pci@0000:02:00.0 logical name: wlan0 version: 01 serial: 90:4c:e5:58:14:34 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=ath9k driverversion=2.6.35-22-generic firmware=N/A latency=0 link=yes multicast=yes wireless=IEEE 802.11bgn resources: irq:17 memory:96400000-9640ffffmemory:96400000-9640ffff
The network is disabled?!? :o i tried to enable it by right clicking on network manager but the
Enable wireless button has been greyed out.
I opened the file /var/lib/NetworkManager/NetworkManager.state and found that the contents are
[main] NetworkingEnabled=true WirelessEnabled=false WWANEnabled=true
I tried to change
WirelessEnabled=true but after reboot it resumed back to the same state.
