Re: Wireless Network Refuses To Turn On in Network Settings

Post by JeremyB »

Tim E wrote:I have this problem too. I have a Lenovo G50-30 running LM 17. When I booted, it wasn't recognising the wireless card at all, so I followed the instructions in this thread and Wireless is now an option in the Networking settings window. When I try to turn the card on, the slider just slides itself back over to OFF.

I have no hardware switch for the wifi card on the laptop - there is an airplane mode on one of the function keys - pressing this toggles the airplane mode slider in the Network settings window but I can't turn the wireless adapter on when not in airplane mode.

I've tried the Network State trick above, but that doesn't seem to make it work. One oddity - when fiddling around to try and get it working before trying the Network State trick, I tried setting the wifi up as a hotspot - this hasn't helped me solve the issue, but when I do the network-manager on/off thing it comes back running as a hotspot, even when it wasn't before I turned the network manager off.

Any clues??
Open a new terminal window and run this with an ethernet connection

Code: Select all

wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script
and paste the contents of the resulting wireless-info.txt using code tags or attach the wireless-info tar.gz
