Vista - connection drops?

hi, everyone well i been having a very bad experience with this home premium vista 64-bit sp1 the problem is, every time i go away off the computer, my screens goes into screensaver(which is ok) then after a while or suddenly my connection just seens to get cut for some reason, so i can't put any screen saver or nothing or go away off the computer without getting this problem, is there any setting how to stop my connection to drop from screensaver? thx in advance

I have never heard of the screen saver cutting off the network/internet, but it leads me to think of 2 other possible problems, 1 which I am battling fiercely right now....

The easy one is a "power saving" setting might be turning off the network adaptor when the computer goes into screen saver mode -- That is easy to fix in the power settings (may be in advanced settings for the network adaptor and/or power options).

The other one is that it is simply disconnecting for no reason at all -- the problem I am having, and many other people in other forums I have visited looking for a fix. I have had my computer for a little over a year now. Ever since I got it, I would have wifi issues from time to time, but USUALLY changing the rf channel (on the router) would fix it for a few months. Now, after anywhere from 1 minute to several hours, it will disconnect from the web, and the network access would switch from "Local And Internet" to "Local Only". In actuality, I cannot even ping my router and all access stops at that point. Also, the wifi speed would drop from 54mbps to either 10mbps or 1 mbps! Sometimes turning off the adaptor (using the switch on the side of the laptop) would fix it for a little while, or restarting the computer would fix it. The signal still shows full on the bar, the whole time. I have a static ip address to my router (a linksys wrt54gs), and the desktop (on a hardwire) still works. Also, my pda will stay connected to the router via wifi, so I dont think its a router issue. My issue mirrors the same issue MANY people are having, from what I read all over forums everywhere, but I have not seen a fix anywhere yet. I did see one link to "vista antilag" on a gamer site, and I tried it. IT seems to be holding much better since I installed it, but I did lose connection a couple of times since the installation. If anybody has seen this and knows the answer, PLEASE SHARE IT!!!!
Thank you
