I have an Airport Express 2nd Generation (Version 7.6.8) that I'm using as an access point for my desktop PC.
My house has a Technicolor DPC3848VE modem and WiFi router with dual-band network.
I set the Airport express to connect to the 5GHz network (the networks have the same name + 2.4 or 5.0 for differentiating them).
All the connection is done without problems, but when I check the Network Icon in the Task Bar, the tooltip says I’m connected to the 2.4GHz network.
Just to be sure I did a factory reset and connected the router again and it still connects me to the 2.4GHz network.
How can I fix this/force the airport to only use the 5GHz network?
