could be the router or some firewall problems

i once had that problem with 2 friends too,

the problem was solved when i stopped using my neighbours w-lan ^^

you should google something about routers and firewalls allowing the xbox internet address or whatever i couldn´t try something back then because it wasn´t my router

Ps: if someone finds grammer mistakes they can keep them, i don´t care, there are plenty for everyone ^^
