View Full Version : [ubuntu_mobile] Wireless broke U/G from 8.10 to 9.10

January 8th, 2010, 06:03 AM
My TP-LINK TL-WN610G not working following U/G to 9.10 which worked very well in Ubuntu 8.04 & 8.10.
The device manager instantly see the correct device as Atheros AR 5001 but it does not seem to even attempt connection. Here is some relevant information.

I removed network manager and installed WICD which reports no wireless network found even though I am right behind the wireless router and all security has been disabled. The wireless interface is set to wlan0. What else can I do?
How can Ubuntu detect the correct device and not connect when this worked perfectly in version 8.10??

It appears from the activity on the forums that Wireless functionality is still very problematic in UBUNTU with little or no tools to troubleshoot through the UI. I have lost 4 days tearing my hair out trying to resolve this.
