wireless not working, but wired does
- by user211762
First of all I'm new to Ubuntu, just bought a laptop with Ubuntu yesterday.
I disable wireless networking in the upper right corner, and I don't have option to enable it back.
I tried a lot of things and none is seems to work:
I installed Wicd network manger, and it says no wireless network found, but i assure you there are several of them as my smart tv can detect them.
when I type rfkill list, I get this:
0: dell-wifi: Wireless LAN
Soft blocked: no
Hard blocked: no
when I type ifconfig wlan0, I get this:
wlan0: error fetching interface information: Device not found
