I have ubuntu 10.10, and at my house I primarily used wired, and it works fine, and under windows earlier today I was able to locate networks, so my wireless card is working.

I'm currently at my girlfriends house, and trying to connect to her wireless internet. When I try to connect, I can't find any networks. I've made sure her network has sharing and discovery enabled, however in my wirelss manager it comes up as blank.

There's the option to add wireless manually, but do I really need to go through the trouble of finding the routers mac address and all that, it should just show up?

Any thoughts as to why this is like this? I could switch back to windows to see if I can connect, but I'm almost positive it's just the linux wireless manager..

If it's a Dell laptop, have you tried this:

works on Dell laptops as well as 'Mini'.

well I finally got it working, i'm not sure what it was that actually fixed it, and i did a ton of commands just one after another, so not sure what helped the best.

i would guess that wicd was the thing that actually caused the fix. More can be read here
http://wicd.sourceforge.net/download.php
and it's easy to install by

sudo apt-get install wicd

after i installed that i opened the wicd interface, which showed all the wireless connections, then when i looked at the regular ubuntu 10.10 manager, it had changed, and now was displaying all the networks, and allowing me to connect to them

this may had been all i needed, but I also did these things, which may or may not help

sudo apt-get update
sudo apt-get --reinstall install bcmwl-kernel-source
sudu rmmod -f dell_laptop

The above three codes, in order, updated the repositories, updated the broadcom drivers, and the last was something for dell laptops, which i have (dell latitite d620)
and lastly, I installed a driver set that uses windows drivers, its nidswrapper, which can be found in the software center easily.


This was frustrating as hell to find a simple answer, but no really complicated steps, hopefully someone else can get an easy fix w/o having to search forever to find a simple solution
