I've just installed my Nest WI-FI bit but can't work out how to install my Epson ET-2700 on the network.
The manual says it has :-
It might be due to how Nest Wifi combines 2.4ghz and 5ghz in a single SSID:
Check with Epson if it supports this.
Alternative is to use an old router or a cheap access point to broadcast a 2.4ghz network only for devices like this to connect to. Or if the printer can be connected with ethernet cable, that's an option too.
