For some reason, my Wifi connection frequently drops everywhere except at home. I didn't have this problem with Windows 7 so I guess it's not a hardware problem. My best guess so far is that my connection timeout is very low so if my connection isn't able to reach the router after a few second, the connection drops. Is that likely to be the problem? If so, how could I fix this? Otherwise, what would be an alternative cause for this strange behavior?

Update: I just noticed my home connection is WEP whereas my university connection is WPA.

What type of authentication does this wireless use? Do you've occasional problems in authentication? Please note that I'm not knowledgeable enough to solve your problem, but the things I've asked can help someone to do it. –  Oxwivi Mar 10 '11 at 6:11
    
You should be able to add some more information to your question by finding the relevant information from /var/log/messages, /var/log/debug and /var/log/dmesg. One thing you may want to grep for is "500ms" - I am having a similar problem here: askubuntu.com/questions/29316/… –  Rich Mar 10 '11 at 7:56

First try:

iwconfig wlan0 rate 54M

This often works if you have an N standard compatible WiFi card.

There are three others solutions that might help:

  1. Update the kernel.
  2. Change networkmanager to WICD. https://help.ubuntu.com/community/WICD
  3. Use ndiswrapper instead of the linux driver. https://help.ubuntu.com/community/WifiDocs/Driver/Ndiswrapper
