My school offers free wifi for students. When it connects, we have to enter our ID# and password to access everything. Everytime I'm in class, it always drops me and says "acquiring network address" about a minute later, it'll say "limited or no connectivity" then a second later, it'll connect again. 10 minutes later and it happens again. My signal strength is always between 3-4 bars and I am using an Intel PRO/Wireless LAN 2100 integrated into my Dell 600M. Anyone know what could be causing this? I use this laptop on my home network and never had any problems.
