Pods. Good signal but flakey Internet

My xfi modem in in the center front of my house and the far left right and back had weak signal.  I installed the Xfinity pods in 3 different rooms and those areas now seem to full wifi strength BUT internet is really intermitted when connected to the pods.  If I go into the room with the modem Internet works great. No stopping on videos or pages loading but go into a room with pods, 50% of the time the internet just stops working even though I show full wifi bars.

I'm wondering if these pods are even worth it.   How do I remove them and get my 5G signal back if I want to eliminate them?  

Thanks
