Turn router off. Pull plug out. Wait 10 seconds. Plug back in and turn on again.

If that does work then it's either IWnet (or w/e the console equivilant is) just failing or you and your friends console/PC are looking at a different set of ports, in which case your best hope is to open up both NATs by portforwarding (portforward.com is useful)

Bear in mind, especially if on a PC and you visit a lot of dodgy sites, that certain ports are closed by your NAT for a reason.

This is getting repetitive.

I have had this same problem on PS3 once or twice
It wasn't anything with my setup etc and sorted itself out both times.
It didn't take more than a couple of hours though.
How long has it been going on and are you PS3/Pc

Pointless me trying to help you on xbox.

What was the computer in the repair shop for.
The reason I ask is if it something Virus/Malware/spyware related that caused your pc to break. When it was repaired it may have had options closed/changed to stop this happening again.
A lot of corner pc shops don't have knowledge of PC gaming systems. It does sound (as abc says) like it could be a port issue though as you can access TDM. As for you and your friend having the same ports open... I'll refer you back to abc. He is probably your best bet unless you have some knowledge, to search the answer yourself.
