up until recently, i'd had no trouble connecting to my home network.  i'd come home, turn on my laptop, and it would connect to my network with no problems whatsoever.  then my roommate did something and completely messed up the network.  i fixed it, but it hasn't worked the same since.  signal strength it barely visible in my room when the router is maybe 30 feet away (in the living room), sometimes it would do the "limited or no connectivity" thing and i'd have to steal internet from a neighbor.  sometimes the transfer rate would drop to 1 mbps.  then that laptop died, and i just got a new one on saturday.

haven't had much time to use the internet on it at home yet because, at first, it was doing the same thing my last laptop did.  today i reset the modem and router (i switched the channel it was broadcasting on as well) and it seemed as though the problem was fixed.  i got strong internet for a good couple hours.  then, out of nowhere, "limited or no conblahblahomgihaetyou"  it did this at work yesterday as well.  and i've realized that after i've connected and lost connectivity, when i try to find other networks in the area, of which i know there are plenty, vista will find NOTHING.  i can search and search and search for networks all day, but until i reboot, NOTHING shows up.

any suggestions??  it is so frustrating having unreliable internet.  at least when i know i don't have internet, i can't get my hopes up like, "oh, maybe it works now.  let me check. *facepalm*"
