View Full Version : [ubuntu] Edimax EW-7128g Wireless PCI not working w/ Ralink RT2561/RT61 Chipset

September 6th, 2010, 12:09 AM
Just installed Ubuntu Studio 10.04 and everything seems to be working nicely except I have no networking.

The card does not appear in the Network Settings GUI. The only 3 tabs I have are General, DNS, and Hosts.

A screen grab is attached.

I'm a long time Windows user trying out some of the best Linux creative apps I can find. So, Ubuntu Studio was a no brainer.
I checked the manufacturer's site for linux drivers and they are available, but I don't know how current. (Edimax site, not RaLink's site.) I opened the file and it looks like it needs to be compiled and installed to work. Something I know almost nothing about. The card is listed as supported in this forum for Ubuntu 9x but I can't find information about it for 10.04

Any help would be greatly appreciated.

PS. I have no networking on the system but I can transfer files via USB flash drives if needed.

Still stuck without networking when in Linux.
