I bought a new wireless network card (Trendnet TEW-423PI, 802.11 G) and about once a day it will just lose connection. Usually after about an hour or so of heavy net use (Limewire, IM's, Internet) it will just quit working. I can check the wireless connection status and everything looks normal except the activity will just stay gray (Blue is what it shows when its working). So i have to restart my PC and then, just like that it will work again. Its frustrating to do this everyday, does anyone have an idea of what i can do? For system info, I'm running XP pro, on a Pentium 4, 2.6mhz, 512mb of ram. Also when i try to disable the wireless adapter that function locks up and i usually have to use the power button to shut it off. (Will not shut off through start menu)

Make sure you have the most recent drivers, that's a biggie. Also, open computer management, select device manager in the left-hand pane, on the right-hand look for network adapters and find your network card in the list...right click it and select properties. A window with tabs at the top will open, each card can have a different set of tabs...generally there will be an "power managemtn" tab, select that. Uncheck any boxes that are checked. Remarkably, Windows will turn off a NIC to save juice even if the NIC is transmitting data. When done, keep clicking okay until all windows are closed.

Thanks for the info. Before i wrote this i did update the drivers, and it doens't happen as often but at least once every 12 hours. Also i checked the setting for power management and it said "Constantly awake". The only other things i can change are the Preamble select (have no clue what this is) and the Fragmentation/RTS threshold (have no clue what those are either). Thanks again though.

Standard level for rts threshold is 2,347bytes; this threshhold deals with fragmentation of frames which becomes necessary when you have more than one wireless client on your network and when those 2 clients are far enough apart that they cannot detect each other(in seperate rooms). This can lead to collisions in communication...its like a few people all trying to talk on a cb at the same time. Decreasing this value can help if you have a lot of interference around (2.4ghz phones that hop frequencies and crappy microwaves mostly).

Preamble is simpler, it simply syncronized communication to make things go smoother..kind of like a go ahead
You generally dont need to worry about either of these settings though

One setting I'd reccomend you change is on the router itself
Lock it into 802.11b and not g this will give you a bit more range and a more stable connection overall. moving from 54 to 11mbps isn't a big deal unless you're doing lots of home networking.
