View Full Version : [ubuntu] Wireless problem with Intel Pro/wireless 2100

Hi :)

I have installed Ubuntu on Acer 371TCi and it has Intel Pro/wireless 2100 card. It seems to be mounted correctly because lshw -C Network shows:

When I want to check 'Wireless connection' after left clicking on monitors in the 'Notification area', 'Enable Wireless' line is grey! I can't put check sign cause it is not active?!?

System/Administration/Network settings: wireless connection is listed and it is in the roaming mode.

What should I do?

Thank you :)

Well, friend showed me on his laptop the same situation. His wifi card is functioning perfectly until he switch it off by pressing a wireless key on the keyboard!!!

And after that, he can not activate "Enable Wireless" in NM left click opened menu...

Please can you help me with my Wireless keyboard button that does not work under Ubuntu and works perfectly with WinXP?

there is solution!!!

I've pressed Fn+F2, after that Fn+F3, and wireless was ON!

In fact, Fn+F2 or F3 doesn't help!!! It seems to be the solution but that time I've pressed lots of keys ;) included the one for system suspend. Efect is similar as I was choosing: Suspend (from turn off menu).

Has anybody idea why WiFi card starts only when waking up from 'suspend' mode,right after having Ubuntu running?!
