Hello there!

Please try changing you NAT type, because in order for you to connect well and to not have such issue s the NAT needs to be Open.

Follow the steps on this link to resolve you issue, the steps you need to follow are "Advanced NAT troubleshooting (single console)":

Sounds like it might be a NAT issue

OPEN NAT MODERATE NAT STRICT NAT

With an OPEN NAT type, you’re able to chat with other people, as well as join and host multiplayer games with people who have any NAT type on their network.

With a MODERATE NAT type, you’re able to chat and play multiplayer games with some people; however, you might not be able to hear or play with others, and normally you won’t be chosen as the host of a match.

With a STRICT NAT type, you’re only able to chat and play multiplayer games with people who have an OPEN NAT type. You can’t be chosen as the host of a match.

Hey there StealthyNaike!

Sorry to hear about the connection issues. To clarify, you are still able to connect to Xbox Live through your Xbox 360 console even if you have a strict NAT, you just may run into multiplayer issues down the road. What kind of games are you looking to play?
If connecting to Xbox Live to play multiplayer games is your goal, I would suggest connecting to a router instead of an Aircard as that would give you a more stable connection along with an open NAT.

Hope that helps!
