Strong Signal, but Internet keeps dropping.

I've recently started working from home, and initially had issues will my connection. I decided to upgrade to the 1200MB plan and purchased and xPod to ensure I have good coverage. I have run the speed test multiple times and it reports that everything is good, service is supposedly over the 1200MB, and  yet I still have and issue were bandwidth seems to drop for 5-10 seconds and this makes video calls practically impossible. 

I've used the app, restarted my Gateway but it has not improved the situation. Frankly unacceptable service for the price.
