I just upgraded my old N router to Asus AC router and added a Xiaomi AC router to be a extender (repeater), when I check the Asus router "connected device", the extender only shows connected in 2.4ghz mode, is it normal?

is the xiaomi operating in both 2.4/5ghz under its own web UI?

Also if you are living in HK 5Ghz often doesn't penetrate through concrete and can only go much shorter distances.

Best use a wifi analyizer app to see how strong your router signals are and make sure they overlap.

Let me get this straight, a phone can only connect to one band, either 2.4 or 5ghz

An extender suppose can connect to both bands simultaneously?
