I can't join a match in arena

Ever since the new update i couldn’t join a match in arena
Is it my network or the update?
Well i just a new modem and it has a lot of data so give me soloutions.

Just download some more RAM for your router - it’ll be sweet after that.

Head over to xbox support, they’ll run you through some necessary troubleshooting stuff which will most likely fix it, if not get onto your ISP and get them to help, don’t take no for an answer!

Not able to match either I think it’s time to try a new game system

masterawesome75, you may be experiencing trouble with matchmaking because your Xbox Live reputation is listed as “Needs Work”. This means you’ve accumulated enough legitimate reports from other players to lower your rep from “Good Player”. I’ve really ever heard of “Avoid Me” rep preventing matchmaking, but it may be something you want to consider.
