Wireless acting weird ubuntu 12.04 LTS
- by Philip Yeldhos
I'm kinda new here, so please bear with me.
My wireless driver is acting very weird. It shows my router's name, but when it is connecting (after entering the correct password), the icon on the tray is like, refreshing every once in a second, while showing the animation that it is connecting. And after a few seconds, error message come up saying that wireless network is disconnected. I installed the drive through "additional drivers". What info do you need? Somebody please help.
