So I'm staying in a hotel for a week and I can't sign in to Xbox live. I keep getting MTU error between the router and internet stage in the network test. The suggestion was to unplug the router and reboot and I went to the front desk and they said they would do so but to no avail. Also for a brief moment last night I was able to connect but 10 minutes later it was lost and hasn't worked since. Is there anything I can do to get this working?
