Re: How to set up a WLAN?

OK, this is a Ralink RT2500 chipset. I've built the rt2500usb module and
loaded it. ifconfig wlan0 up worked.

Check out module-assistant for automatically building extra modules for your kernel.

I'd like to connect to the public network that's set up around the campus.
What do I have to do to make it happen? Everybody else's Windoze and Mac laptop
simply connects to whatever network it happens to find.

A standard command to check for available networks is "iwlist scan". Run as root.
There is a utility with the promising name "iwspy", but that tells me:

  wlan1 Interface doesn't support wireless statistic collection

Don't know what that means except that it doesn't work.

There are two Debian packages for this chipset: rt2500-source and
rt2x00-source. They provide different modules, but neither really seem to
Try building with module assistant. It will help you prepare your system for building. run dmesg after loading the module to see any error-messages and other info. It should report your card detected. Post here if there are messages you don't understand. Never used the usb variety, might need something extra loaded for that to work.

Once you have the module loaded and running ok, check out the config file /etc/network/interfaces (which has a manual page). Together with the results from iwlist, you will have the info you need to make "ifup ra0" or "ifup wlan0" work.

For gui use, both kde and gnome have offerings, once you have the needed modules loaded.
