Can I use a router or a wireless router and still play Halo 3 online?
A4: Yes. You can play Halo 3 from behind both wired and wireless routers. However, a poorly configured router or a router that is configured incorrectly can prevent you from joining games with other people. This issue occurs even if you can log on to Xbox LIVE. The reasons for these issues are so diverse and unique to each circumstance that it may be impossible to determine the specific reason for some issues. Also, wireless connections may be less reliable than some wired connections.
