This wifi card solved my problem. My Xbox One controller kept disconnecting from my Xbox. Sometimes all the time and sometimes just randomly for a few minutes. I've followed the Xbox Support troubleshooting guide to no avail. Bought new rechargeable batteries, used regular new batteries, unplugged or turned off other wifi devices, did a hard reset, did a resync, made sure the controller was up to date, even bought a new controller. Still does not work. I thought oh well and went hard wire (which obviously worked). I searched the internet and came across a Reddit thread that described my problem and its solution. OK, it worked. It was a wireless card. Taking the Xbox apart and putting it back together was a pain. The hardest part is just aligning the tabs backwards. Just look it up on YouTube how to do it, but listen and watch the video first. It's 2 screws and a wire that just pops out.
