Are there any routers that are recommended for playing Halo 3 online?
If you live in North America or certain parts of Europe, look for routers that are specially marked as ‘Xbox LIVE compatible’ or ‘Windows Vista compatible.’ These routers have been tested specifically by the Xbox LIVE team to make sure they work. If you can’t find one of those, try to find a router that is marked ‘Universal Plug and Play’ or ‘UPnP.’ (Once you get your router home, use its configuration tools to make sure Universal Plug and Play is actually turned on.) Some routers require a firmware upgrade to work properly with Xbox LIVE; check your manufacturer’s website for firmware downloads.
