One PC disconnecting entire home network

Specs: Windows XP
Hey guys,
Have a weird problem here.

I have a home broadband network setup, where 1 computer (mine) is connected directly to the ethernet port in the router, and 3 other systems are connected via Wi-fi.

Now the internet works fine when 2 of the other systems are on, as well as mine.
But then when the 3rd connection is made, the internet connection just ends for us all, giving us time out messages, and failing to detect network etc.
Another thing is that when I reset the router, the internet works fine on all systems (even the problem one), for about 20 seconds, before seizing up again.

I've also connected this problem machine up via the ethernet cable, directly to the router, and again it ends the other connections- so it's obviously not a specific Wi-fi problem with the laptop.

His O.S. is windows XP, and the router is a netgear WGR614.

Any ideas what can be causing the problem or how to resolve it? Thanks

Obviously, the 3rd PC needs to be cleaned. Download, update & run anti malware from

Malware/virus's usually don't behave as suggested. They want the network working so they can infect more pcs. If just this pc had been hacked and was broadcasting spam that should be clearly seen in the transmission count in the router.

Not that a blanket wipe and reload of the system should/could fix the issue, it is usually the last resort.

First thing I would suggest is when the problem occurs do some testing. Ping the gateway. Ping the problem pc.

Do a ipconfig /all at the problem pc and one from one that works when the problem is occurring and post them here for review.
