RouterOS Wireless Networking
1

Hi, I have 02 radio netmetal 921UAGS-5SHPacT.
When performing the link, it shows the following signal values

as you will see in the field Signal Strength Ch1 it’s empty so the link is lousy

I have other equipment the same models that show values ​​in the 3 chain (Signal Strength Ch1=-57/-56 dBm / Signal Strength Ch2=-57/-56 dBm / Signal Strength Ch3=-97/-96 dBm) and the link works very well.


but in this link our empty other indicators of signal, if they were the pigtail the values ​​would show high values, but not empty
help, something needs to be configured?

What device is connected there, and does it have 2-3 chains?
Did you enable the other chains in the AP settings?
