Most modern operating systems (Mac OS X 10.5/10.6, Windows Vista/7) remember which wireless access points (APs) they have connected to in order to more quickly re-establish a wireless connection. This is useful in a home network as the computer quickly finds your wireless network and spends less time searching for available networks.
However, with so many access points on campus, your computer may save the information of an access point that is not nearby to your room or office and attempt to establish a connection with it. This can result in a poor wireless connection due to the access point not being the closest one available with the strongest signal strength.
As a result, it is useful to remove the saved/remembered networks from your computer, forcing it to establish a connection with the nearest router with the strongest signal strength.
