Cannot connect to Wifi - IP issue?

Hi

Hope someone can help me with this - have seen similar-ish issues in past posts but nothing that can fully help me.

Basically I have just moved in to a new houseshare - there is WIFI in the house, cable broadband (NTL IRELAND).

On my Macbook Pro (2007) I am having an issue connecting to the internet. Had the issue on Leopard and, now, on Snow Leopard.

I connect to the home network, but cannot get internet. I tried with DHCP, but Airport says I cannot connect due to the IP address being self assigned?

I tried putting it to Manual setting, inputting 192.168.1.5 (for example) as my IP and router as 192.168.1.1, but no joy.

The only way I can get it to work is to enter Airport diagnostics, reset the router when instructed to do so by Airport, and waiting for the correct IP address to be assigned. But when I shut my machine down and start up again, it's gone again. I need to go through the dfiagnostics and reset process again.

But the really annoying thing is I have Windows XP installed under boot camp, and Windows has no problem! It just automatically connects without and fussing. It just works!

Has anyone any ideas? Driving me mad, I don't like working in Windows for general browsing.

;-(

Thanks a mil!

 

How did you do that? Through Windows?

I have popped down to a friend's house who has the same internet provider and have had no problems, so there's an issue with the router setup I suppose. Just annoying that Windows XP doesn't see it as a problem.

Could it be something to do with Static/Dynamic IP addresses being used by the router?

Doy.

I'm going to try a long reset when I get home in case it is a case of running out of IP addresses.

I love the internet when it works. But when it doesn't ...

 

Yes indeed, I'm clutching at straws.

I had not thought of logging in with another account. Thanks, I'll try it tonight whil crossing my fingers and my toes.
