RB4011 WiFi showing only 3 chains [SOLVED]

DanielJB · Sat Mar 09, 2019 4:08 pm

Does anyone else with a RB4011 WiFi variant on RouterOS 6.44 find stats shows only strength from only 3 out of 4 chains for the 5GHz radio, ie no signal-strength-ch3, despite rx-chains and tx-chains being set to 0,1,2,3?

/interface wireless registration-table print stats
0 ... signal-strength-ch0=-70dBm signal-strength-ch1=-62dBm signal-strength-ch2=-64dBm ...
1 ... signal-strength-ch0=-93dBm signal-strength-ch1=-91dBm signal-strength-ch2=-87dBm ...

Yes, using RouterOS 6.44.

all 4 chains..
signal-strength-ch0=-81dBm
signal-strength-ch1=-80dBm
signal-strength-ch2=-87dBm
signal-strength-ch3=-82dBm

Thanks lipo. Can you check on RouterOS 6.44.1?

It may be that Mikrotik removed the updated WiFi driver as on 6.44.1, I still see:
