Disconnecting from Xbox Live on Xbox 360 in YouTube and Netflix

Hey, this is my first post! As the name suggests, I keep losing Xbox Live connection whenever I go on YouTube or Netflix. On Netflix, I'll usually get 20 minutes into a movie then it disconnects. When I try to reconnect, I get the error code 80151904. However
when I test the connection, it's fine and I'm able to connect again!

As for YouTube, I go on and every now and again a message saying "Sorry YouTube is currently unavailable". But the message goes away and the video keeps playing. After a while, like with Netflix, I lose my Xbox Live connection and get the same error code.
I've also gotten the error code 8b050008-00000000-00000000 a few times too. I've looked everywhere on the forums for answers and I've tried everything. I've tested my connection strength and speed (which is fine), I've cleared the system cache, cleared system
updates (and reinstalled them again), deleted my profile and downloaded it again and deleted and reinstalled Netflix and YouTube. Please someone help, I'm going crazy here!!!!!!

Disconnecting except when on multiplayer

I seem to keep disconnecting every time i am doing anything but playing multiplayer. i cant watch netflix or youtube, and if i play a single player game it will disconnect me from xbox live. Just recently got xfinity and am using an ethernet cable. anybody
know the solution for this?

 

Xbox Live

Netflix. Changed my password on the website. Rebooted the Xbox.

Got disconnected from live AGAIN. rebooted Xbox. Loaded Netflix app. Logged in with new password.

Netflix worked. Stupid bug.

Xbox live is still playing silly buggers. Still randomly disconnecting after sloooooooooow login (or a failed login). Very very annoying.
