Two days ago I bought the RBD53iG-5HacD2HnD and transferred the necessary configuration from my old RB951 (DHCP, Wireless Access list). I reconfigured the WIFI network. I connected the Router instead and after several minutes I noticed the problem. Namely, the 5GHZ network comes and goes! One time it can be visible for 1 hour another time 5 minutes! Devices connected to it lose connection with the Internet, and the phone switches to the 2.4GHz network!
5GHz network is set Mode: ap Bridge, Band: 5GHz-A / N / AC, Chanel Width: 20/40 / 80Mzh XXXX, Frequency: auto What could it be? Where could the problem be?
