1st thing I'd check is that you're running the latest S6 Edge firmware.

Second I'd turn off Smart Network Switch under WiFi - Advanced.if it's switched on.

Lastly if you have a Hub One I'd try separating 2.4 Ghz & 5 Ghz in router settings & seeing if the phone has a more reliable connection using one or the other. The S6 & S7 are different under the hood & so will have their own performance positives & negatives
