My base station goes offline all the time. Sometimes multiple times in a day. I used to have it plugged into a Netgear extender and I thought that maybe that was the problem. I purchased an Xfinity Pod but the problem still persists. I am not loosing internet service to have this happen. My router is in a different room and all the other devices that use Wi-Fi that are in different rooms do not have a connectivity problem.
Could you wire the base station into the main router? Or try to have the base station connect to your main wifi network wirelessly?
