Is it possible to use mesh network for X1 cable 3rd party apps

I understand the cable box connects to my internet gateway in order to use third party apps like Amazon. For the den television however, it is too far from the gateway and the wifi signal is weak.  As such the apps (well, only tried Amazon so far) are very slow. I installed a mesh network to overcome the weak signal and would like to know if it's possible to have the box in that room connect to the mesh network instead of directly to the gateway? Thanks.
