Wireless network connection keeps disconnecting

ok I have two laptops both are Thinkpads one has XP and the other has Vista
the one on xp has issues all the sudden connecting to our wireless router
I am not sure what to do to diagnose the issue
all the while my vista thinkpad stays connected and works fine non stop

on the xp machine I go into Wireless Network Connections and I see the wifi there highlight it and hit connect and it does its thing and seems to connect the icon at the bottom still has a red x but I can brows the internet fine for around 10 min and then all the sudden it stops
but everything is fine on the other computer
if I restart the xp machine and try again I get another 5 min

where do I start?

1. Re-install Drivers, get new ones from Manufacturer
2. Delete Wireless connection and re-add
3. If Laptop is under warranty call manufacturer as it may well be a bad wireless adapter.

Hope this helps!

If wireless almost out of the range, it can do that- might want think the way increase signal.
On mean time, right click "network icons"- "reapair" - instead of powercycling.
Simple way  increase signal- move wireless router away from the metal, raise above ground, move to the most "central" location, use "external antenna"- you can find a lot of variation on a web, just search for it.
Also you can "ip caonfig -all" from PC CMD, and assign this range manually, to prevent extra DHCP traffic, other PC will not grab the same , if one already detected.
There is a lot "small" things you can do , but above is the first one.

Look for interference from other devices in your home. 2.4 Ghz phones, microwave ovens etc.... Because the problem is happening on both machines, it is either interference(less likely) or a bad wifi access point(start here).
