I am new to the XE75 so I may be a bit confused. On the 2.4 and 5 bands I can share the same SSID. When I enable 6e wireless since I have a few 6e devices the app defaults to a new SSID for the 6e. I haven't tried yet but am I safe to use the same SSID as my 2.4/5 network? If possible are there significant reasons not too? 

BTW: Not sure how Tplink measures the coverage SQFT. They quote major improvements over my previous system Nest Wifi honestly I don't see it. I tried to use 2 devices but ended up having to use 3 like my old Nest. Also the speeds were the same. The reason I am sticking with the Deco is I can disable Wifi Bands making bringing new HomeKit devices online and most mesh systems are a pain. I am not knocking the system I really like it much more configurable than the Nest. Just was expecting less hardware based on the coverage numbers they ae throwing around.

TIA,
