I am running ubuntu 11.04 on a laptop and recently both bluetooth and wireless internet stopped working for no reason (maybe because of an update? accidentally pressing a key combination?).

ifconfig -a gives me eth0, lo, and wlan. nm-tool gives me eth0 and wlan are unavailable. Running lshw -C network, recognizes wireless interface but says -netwok DISABLED. Running rfkill list lists Bluetooth and Wireless Lan.

Both bluetooth and wireless are disabled in windows too.

I tried to play with Fn-Fx keys; no luck. Not sure what to do now.

Hello, if this is happening crossplatform, it suggests that nothing in Ubuntu is causing/can fix it. Make sure you haven't switched then a physical hardware button (frequently located on the F1-12 row). I've voted this question for closure as there's nothing really to answer. – Jacob Johan Edwards Sep 5 '12 at 20:59

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet.

The fact this is happening cross platform suggests to me either a hardware switch or hardware failure.

how can I make sure it's hardware failure or no?! – eli Sep 4 '12 at 23:28
I just realized that there is a little button on the side of the laptop that turns wifi on/off. It slides easily. Stupid design ! there is already Fn-F5 for that. – eli Sep 4 '12 at 23:42
