The network settings are correct, so I can discount the laptop, it cannot be the cable, as it does the same thing here as it does there, and my cable is working right now, otherwise I would not be writing this, so discount the cable, therefore the conclusion is as I thought, a dead router.
There is no factory reset on this particular model, and it is a pretty old one. I bought him a 4 port Netgear DG504T on Ebay last night for $A36.00. I've asked him to call his isp to get the settings for the router so I can set up his username, password etc. As a bonus he can now connect the X-Box and the other computer, that should eliminate the internet wars between the brothers.
Thanks everyone for the advice.
