Hi all,
I was really enthusiastic about using _only_ Linux and still am. I loved it when I installed Ubuntu, to see that my centrino laptop picked up a wireless internet connection automatically (well, almost). (I use IPW2100 )

Now I have a problem using the laptop in different wireless networks.

When I boot up at home, the wireless internet works fine, since I had installed ubuntu while at home, but when I am at school, the laptop does not pick up the wireless connection there. In fact, I have tried a handful of networks, and the wireless seems to work only at home.

Can somebody please refer me to a guide that will tell me how to set-up and troubleshoot wireless networking on my laptop? What I would really love is a guide that answers the question "How do I get my laptop to detect multiple wireless networks and how do I switch between multiple wireless networks effortlessly?". I hope the answer is not "Use WIndows XP" :P

Thanks folks.

I am a technical consultant who recently purchased a i9200. I have been looking at different utilites to accompless this tax. I have only found two: Kwifimanager for KDE (included with fedora 3) and NetworkManager for Gnome. Both of these have many issues. Kwifimanager doesn't appear to know hoe to save multiple networks for switchcing with out reboots and network shutdows. NetworkManager finds a network, connects, lets you use it, then drops you after a few minutes.

I am still looking into this..

There is a small simple and nice tool on SF which I use to switch between network confs, wired and un-wired

You basically edit the conf for the network details (IP NM DNS ...)
and by calling

switchto "ProfileName" it switches

here is the URL

Hope it helps
