There is a WiFi connection issue. – Smartphone Connect Review

The app does not always connect to the base and I need to deregister and register again most of the time. It’s not a very stable software it seems. One more thing the problem is more evident with the upgrade of iOS to 11 and so on. I believe a famous company like Panasonic will not let this go on. As a matter of fact I bought this phone a year and a half back only for this has a Wi-Fi function. So I am kind of upset for its WiFi performance. Other features of this phone are simply excellent.
