How do you check ban time? My WiFi has been spotty since I got home today, and I was recently banned for DNF games. Just purchased an ethernet cable because I think router distance is my issue. Can someone either help me get in touch with a support person to discuss the ban, or at least point me in the direction of information on how to view ban lengths?
Your ban message should have stated how long your ban will last for.
If you want to see the message again, close halo 5 and re-open it to the arena screen. it should tell you how much is left.
