Keeps disconnecting from Xbox live while watching Netflix

Okay so I have used a friends account to use her xfinity wifi hotspot and home, since I connected the hotspot to my phone I realized that hey maybe I can do the same for the Xbox. I searched on ways to use the xfinity wifi hotspot with the Xbox and it
told me that if I connected a cell phone to the network and used the cellphones MAC address where it said to configure the settings that it would work I did it and surely it worked so then I just continued to use the Xbox with the xfinity hotspot no problem.
Now I finally was able to pay my Comcast xfinity bill and now my internet is back on I connected it to the modem and it connected no issue and was working for about 5 mins and then it disconeected and I got an error, it's been doing this for the past day and
a half and I don't know what to do to fix he problem , some of the suggestions that it gave me was that there was and IP address error and then something about a static IP address but mind you I'm using the hotspot so I can't disconnect and reconect the modem,
also when I connect it to the regular home network that's actually a modem , it connects perfectly fine. It disconnects and shows me error help ?!

:)

 

Whats with all the updates?

I've been having problems disconnecting while watching Netflix. Yarrrrrghhhhhh

 

Xbox Live and Netflix

While watching shows on Netflix, a message pops up that I've been disconnected from xbox live. I am then signed out of Netflix and when I go back to the home screen, I am immediately signed back into Xbox live again. I have tried clearing the system cache
and also deleting then reinstalling Netflix, but the problem keeps recurring. Any suggestions?
