Xbox One connection/profile issues

Hi,

Currently I'm experiencing two main issues:

1. When I'm playing a game it randomly signs me out of my profile, causing me to sign back into the account and making the game restart.

My Xbox profile is shared on another Xbox not even 100m away from my personal one, however it never gets signed in since its simply there for sharing games with family members.

I have deleted my profile and re-downloaded it before and the first time it only fixed my controller its vibration to function properly again, few attempts later it just keeps signing my profile out at random times.

2. I've got Xbox Live and am using a internet cable to be able to play online, however from time to time it randomly claims I've got no internet connection and few seconds later (10 or so) it reconnects; causing if its a online game the connection to drop.

As aforementioned I've got both Xbox Live and my account on another Xbox console and I'm sure nobody else has access to it or is logging into it, else the message would state that someone else logged into my profile from another console.

Does anybody have a fix for it?

:)
