I recently moved to a different country and brought my Asus RT-AC68U router with me. I have it configured to use separate SSID's for the 2.4 and 5ghz bands and it's running Merlin firmware.
In my old home I had the modem in bridge mode and the router took care of everything. In my new place it's not possible to configure the modem this way due to restrictions from the internet provider, but I still managed to connect my router and use that exclusively for the WiFi network in my house.
The strange thing is that my HTC One M7 and my wife's Samsung Galaxy Tab S are no longer able to see the 5Ghz SSID, nor can I manually configure them on the devices. Previously they connected just fine.
Does anyone have any idea why this is suddenly not working and, more importantly, how I can fix it?
Thanks in advance for any help.
