Internet Connection keeps falling over

Hi folks - I wonder if anyone could help me with a problem I've been stumped by?

In the aftermath of a problem we have overcome, but not really understood, I have got a strange connectivity problem. Our internet connection failed completely a week back, and after replacing modem with an identical unit, and re-installing our account with TalkTalk with their connection software, we got our internet back on the main PC (connected to the modem via USB). However, we then found that our wireless router connected to the modem wasn't broadcasting.

We replaced it with the wireless router that I had from a previous address. This we have found to work fine also, so that a laptop we have, links to the wireless network from the router without a problem.

My problem is that a third compueter connects without difficulty, but within just a few seconds the connection fails.

So, I have two computers that no longer have a problem connecting to the internet, one linked by USB to the modem, the other via a wireless router. But I have a third computer that has a connection that has to be continuously re-made.

Interestingly, it never disconnects during the download of content, as demonstrated by always being able to stream video clips without disconnection.

The 'problem' computer is running Windows XP 2002 (home edition), SP3. Windows Firewall, and AVG Free anti-virus. I also have Adaware Anniversary Edition running AdWatch Live - this is all the same as before we had any problems. (Turning off the AV software and/or Windows Firewall doesn't make any difference).

The Modem is an MT882 (from TalkTalk, our ISP), the Wireless Router is a Netgear WGT624 v3. The Wireless card on my PC is also Netgear - WG311 PCI Adapter.

Any thoughts?

have you tried disconnecting and then search for networks and connect again.

Hi nob14. Yes - it's what I have to do to re-connect.

The computer has no trouble finding and connecting to the network. It just falls off a few seconds later.

have you tried giving it a static IP address. Is it lost from the router when it goes? Look in it and see what MACs are connecter.

I don't know how to give it (the PC?) a static IP address - for all I know it has one. Is what lost from the router? Look in what, to find what?

Sorry - that's all beyond me. Can you explain like I'm a dummy? (I am).

Just one bump for this. The key to this does seem to be about the connection being idle or not.

When I have, say, an internet radio station running in the background, the connection remains. But if I stop streaming the radio station, the connection fails within a few seconds.

Any clues?
