So recently I've been having some issues with my One. I'd get randomly disconnected from Live, and when this would happen my controller would crap out to the point where my One was unresponsive. This happened on 2 separate occasions and each time I didn't really investigate, mainly because I was inebriated at the times and just used a different system instead. But today I tried to get the Gears Beta going (which I found out you have to register for) and had the same issues so I said WTF? At first I thought it might be my controller so I gave it new batteries, but still messed up. Then I got out my new Xbox One PC controller but again had the same issues. Then I tried a hard reset and still nothing. Finally I decided to try the Network Troubleshooter and it turns out that my wireless card is broken and I need to send my One in for repairs. Fantastic. Luckily I can still connect via Cat-5 but after this week I'm going to have to send it to MS to get repaired. Still annoying that I won't be able to play some of my stuff for a while.
I would check your hardware again before you send it in. The day you posted this I was not able to do anything on Xbox Live either. They may have just been having problems that day.
In other news, the Gears beta is broken for me. I didn't register for it but they sent me a download code and a separate activation code saying I was registered as a preview member. I've redeemed both of those codes but when I tried to check it out last night everything would load up and then I would get a message saying I'm not authorized to participate in the beta.
I forced the app closed and tried to redeem my codes again but since I had already redeemed them it says they have already been used. The message I'm seeing in the beta tells me to go to gearsofwar.com and register for the beta. When I go to that website and sign in the first thing I see is a big banner saying "you're registered for the beta!''
So basically my Xbox tells me I can't play the beta I downloaded until I register on the website but the website won't let me register because Microsoft supposedly already did that for me as a preview member. I messed with it for about 20 minutes last night. I'll probably give it another shot tonight but if it doesn't just work when I launch the game I'll probably just give up on this beta.
