Hello All.
About a month ago I changed my office AP to RBcAPGi-5ac2nD and
finished 2.4Ghz and 5Ghz settings and using well...

This time I changed the factory AP to Metal G-52SHPacn, but there is only 1 Wlan.
Metal G-52SHPacn Can not use 2.4Ghz and 5Ghz at the same time?

i try to connect RBcAPGi-5ac2nD and Metal G-52SHPacn by winbox and compare each parameters...
and it's little bit different.
Is there no way to use both frequency at same time?

Any reply would be appreciated... Thanks.

No there is only One Interface so it is impossible to use both Bands at the same time
