Since update 14/04/2014 when i do a network test on the xbox one i have no mtu number and no upload speed ,however in upload packets lost is 0%. Due to this i can't do a multiplayer test , i get a message unable to carry this out message check network . However i can still play titanfall and have an open nat.
Things i've tried
1)power cycled xbox and router
2)factory reset router
Any one else have this issue and have a fix
Thanks for the help in advanced
