Wifi calling

We have a xfinity gateway downstairs and a xfinity pod in the main floor hall way. We use wifi calling for our cell phones and every time we walk passed the the pod in the hallway the calls are dropped. The call can be redialed on either side of the pod with no problem. it only seems to happen when walking passed the pod. Any thoughts or help? Wifi calling seems to work fine every where else in the house.

Thanks
