Connecting to my wireless network

Asked by jimjinphx

I installed Ubuntu 9.10 on my laptop, which also has Windows XP installed. XP recognizes my wireless network, but 9.10 sim[ply gives me the message *network not connected*. Suggestions for getting this to work?

This is your wireless card. Broadcom sucks.... Just to let you know. :)

The first step I would try is going to System > Administration > Restricted Drivers. If you see any Broadcom drivers then install them. Reboot and see if any magic happened.

If that doesn't work then try this:
 sudo gedit /etc/modprobe.d/blacklist (Unless you know vim or nano - those are better than gedit)
Add this on a new line at the bottom
 blacklist ndiswrapper
Save and reboot

I really hope this helps. :) Broadcom sucks but it's been dealt with a lot in the Linux community.

Can you help with this problem?
