what happens if you connect via ethernet to the router using teh desktop? will it still not assign an IP?

Good idea. Can I just unplug the router and take it to the rogue PC, and connect it?

What will the result tell me?

have you had a update in windows that mite have do it ,???/

On my laptop I've downloaded the little patch to stop Service Pack 3 being installed, as I've heard so many bad things about it.

But I've not done it on that PC. Perhaps that's the problem.

I can't.

The router is upstairs. I don't have a telephone point downstairs next to the rogue desktop.

Every now and again my laptop likes to try and connect to one or more of the unsecured wireless networks that are on the go round me, could it be your laptop is doing the same?

To see what or who your connected to either hover your mouse over your network connection icon (wee tv screen to the bottom right of your screen) and it will show you who your connected to, the signal strength, speed and status (or at least mine does). You can also right click and chose view wireless networks.

Have you tried rebooting your modem if your a cable customer. Just unplug it from the mains for 2 mins, restart your computer then plug it back in and this should refresh your line and if you have a dynamic ip address it should give you a new one.

Same for your router, you should have a reset button on the back of it, or in your config page to restore factory defaults, again worth a try. You can also do a release / renew in there most likely (well I can in my Linksys).

Failing that do an ipconfig /release to close your current address then ipconfig /renew in MSDOS via the command prompt. (Google this if you want more info).

Hope this helps.

Thank you, cheeky.

No, I don't think it's trying to connect to any other network. The only other network I can see is my neighbour's. I set my network up myself so I know its name etc. (In fact I have to rename the network regularly as the desktop falls over so often - I've now progressed to dating it - i.e. May25b is the current one...)

I've rebooted the router several times, and also disconnected and reconnected it. I don't use a modem - it's a wireless adapter, but I've uninstalled and reinstalled it.

As I said in my OP, I've tried ipconfig/release and /renew.

One workaround might be to - instead of letting the router set the IP addresses of the computers in your network - to set them manually?

I've tried that. I get a false connection: it says I'm connected perfectly but there is no connection.

HC, have you tried running Zero config? This worked for me when I was having the same problem with a wireless adaptor.
On the computer that you are having problems with:

Start>Run>type in services.msc
Scroll down the list that opens and find Wireless Zero Config, right-click it and select start from the menu.

Thank you to everyone who's made a suggestion.

I shall have to ring Netgear in the morning. But they talk to me as though I've never seen a computer before, and can never tell me why the problem occurs. I want to know why, so I can deal with it myself.

Yes. It's in my endless list above of things I've already tried.

Thank you, though.
