No Wireless

**saurabhgeo** · April 17th, 2010

I messed up my computer so did everything again from beginning
First i installed Windows Vista and associated Drivers hence made wireless working in Vista

But now when i come to newly installed ubuntu 9.10 I find that nm-applet do not detect any wireless network

Here is output from

lshw -C network

Just saw a really interesting method in post 6 of this thread in beginners forum for your card, if I had a card I would try it just to see if it works--I downloaded it anyway.

Post 4 of this thread is the tried and true method
