Well at least for me, i was losing connection constantly and it's very verrrry frustrating!
Then i found out if i change some Superhub settings, it fixed it.
1) Go to your Superhub settings (type 192.168.0.1 in the internet address bar)
2) Click ADVANCED SETTINGS
3) Click WIRELESS RADIO and change the 5ghz wireless to 54mbps.
4) Save settings and connect your XB1 to the 5ghz network.
PS: This may not work for everyone. Let us know below if it does or doesn't.
They can join 2.4ghz
BUMPED so people can see the fix. This fix needs to be shared and known by the VIRGIN TEAM!
