I think you'll get a faster response if you post this in Networking & Wireless, along with the output of "sudo lshw -C network" (without the quotes)

chili555 or someone will be along to talk you through it.

Try this.

Go to System >Administration > Hardware Drivers. I believe it is there. There is what used to be called "Restricted Drivers" If its an Intel card it might need some extera packages to be downloaded. Some hardware requires restricted drivers to be installed becasue there not normaly in the normal repos.

Also have you edited the sources.list file to add exter repos, by default only most are enabled but there are a few more we can enable.

Also please post the output of these commands:


lspciand


iwconfig:)

Looks like you have a Broadcom card. I don't have the guide at my fingertips at this moment but I will post the guide for you when I find it. I believe there is one out there. I remember seeing on not to far back.

Also...

Did you got to "System > Administration > Hardware Drivers" ? Is your broadcom wifi card sow up in there?

Also...

Did you edit your sources.list to add the extra repos?

Keep us posted, We want to get this working for ya!

THANKS!,

I use fwcutter. I could never get ndiswrapper to work. I really think my computer hates me =[.

Use either, try ndiswrapper first though. it's much better.

If you install ndiswrapper correctly, and you have an applicable card, it should work. The only risk is inappropriate installation, which the step by step is meant to fix.

Then again, fwcutter did NOT work on my broadcom, so I can understand.

I had the opposite. I did step by step and still didn't fix my ndiswrapper. I was forced to use fwcutter because ndiswrapper didn't work.
