Did you reset the ROUTER?
Yep, made no difference as far as I can tell.
Thr manual SAID 5 or more seconds on the reset button to restore factory settings. I gave it 30 to be sure!while your computer is connected to the router do a
ipconfig /release
When it's done do a
ipconfig /renew

Are you able to get an ip?
Connected to the PC with the modem on board too, or straight through PC---Router?OK, funny story.
I set up the router, and left it for about 15 minutes while I went out.
Came back in and managed to access the router status page, which I couldnt do before for some strange reason.
The router had a reboot option, which I hadnt tried before, so I thought what the *censored*, it cant make it any worse.
Lo and behold, the router is now fully working, and found ALL the neccessary settings ITSELF.
I just opted for google, and it worked, and its still up and running as I write this post!
I think ill put it down to one of lifes great mysteries, like what women are thinking!!

Thankyou VERY MUCH for all your assistance and support, the router WOULD have been stomped long before now if I hadnt had a resource like this to call upon.

Sorry I posed such an awkward question!

AllanHehe networking can be a strange beast at times... but I'm glad to hear it is finally working.Im trying to set up my wii now, and am struggling to get some sort of update it needs.
Done some mooching around, and the Nintendo website has suggested changing the channel the router broadcasts on.
Am I able to do this without it interupting the set up?Yep, changing the channel WiFi broadcasts on shouldn't affect your setup.
