Intel 5100 seems to overheat and disconnect? Upgrade paths?

Problem
I swore I was gonna get rid of the 5100 the day I got the notebook and never did. I am 2 floors above my router and usually show 19 to 27% signal strength on the router side. When gaming online it cuts out entirely after awhile losing all connection, moving down a floor fixes the problem.

Current Solution
I took the bottom off my notebook and put it back on my cooler. Seems to solve any drop out issues so I assume my original assumption that it was overheating is correct.

Available Routers
I am using a WRT54G v2.2 with DD-WRT and was planning on getting my WRT54G v7 with High Gain Antenna's out of storage. This should help, the reason I am doing this is actually to use the v2.2 as a client adapter for a bluray player.

Card or Router or wait?
My laptop has 3 antenna's and a full height slot. I need to do something now but its also a bad time to spend any money. Do the 6200/6300's have anything to offer against my current pair of routers, like the 6300 and the extra antenna or running cooler atleast? Or would it be better to spend like 25 to 30 on a decent brand N router (DLink probably) in pairing with the 5100.

I have had no issues with the 5100 until my recent arrangement of being so far away.

 

So much for the fail thread, im so frustrated at this point the 6200 will be here in a couple of days. Paired with the router in storage antenna's hopefully i will get somewhere.

 

Many wifi cards are both heat sensitive performance wise, and have a slow drop in performance when run hot for a long time. Sounds like you might be experiencing both things. My old Emachine ran it's poor little atheros card right over the edge and killed it (didn't help I was running a dual core 2.4GHz CPU in a machine made for a single core 1.6, though I did underclock it to 1.8GHz. Replaced it with an Intel card, not sure which one, and it's worked fine ever since.
