Who set the wireless router up? Is your brother's PC plugged into and using it?

If you have an IP addrress (192.168.x.x), then your problem may be DNS related. Can you get to this web page?
http://17.254.0.91
If you can, then it's a DNS problem. You need to talk to your brother to find out what his ISP's DNS server address is.

I'm wondering if the gateway is wrong. That would explain why he's getting an IP but not able to get out to the outside world.
Look on your brother's PC and see what the setting for the gateway and netmask are.
frankblundt said:yeah, could be - i asked him what the Router ip was on his brother's machine but he seemed a bit coy about that so i only guessed it would be 192.168.0.1 (cos it doesn't sound lkike any configs been done on it, also that DNS he gave sounds odd to me 4.2.2.2 ?
ellow% nsl -sil 4.2.2.2
Server: 152.16.198.100
Address: 152.16.198.100#53
Non-authoritative answer:
2.2.2.4.in-addr.arpa name = vnsc-bak.sys.gtei.net.
Authoritative answers can be found from:
2.2.4.in-addr.arpa nameserver = dnsauth1.sys.gtei.net.
2.2.4.in-addr.arpa nameserver = dnsauth2.sys.gtei.net.
2.2.4.in-addr.arpa nameserver = dnsauth3.sys.gtei.net.

Do you get an IP address along the lines of 192.168.0.x? If so, try and open Safari or another web browser. Try and go to a website, any website.

This doesn't happen do be a D-Link router, is it? There is this thing called a preamble. Don't worry what it is, just know that there are two versions: Long preambles and short preambles. I couldn't connected to my girlfriends D-Link because the default was to use a Short Preamble. Everything connected to the router except my iBook. When I changed the setting to Long Preamble, everything worked including my iBook. (Or I may have changed it from Short to Long, I can't remember)
If this is a D-Link, log into the router and select Advanced then Performance. Look for the preamble settings. Change it to the opposite of what it is.
If the preamble settings aren't there, or this isn't a D-Link, check the manual to see if you can change the preamble.
I hope this is your problem so you can get up and running.
