Do you have to use all of the AP7161's radio antenna connectors? Are the radios configurable for 2x2 or 3x3 in the GUI or CLI or is it just a matter of not using certain antenna connectors on the AP?

Hello Ian,

It's always advisable to use all antennas for best coverage; however, if you decide not to, then you will have to change the Antenna mode in the config depending on the number of antennas used:

Example, if using 2 antennas on radio 1:
>en
#self
#int radio 1
#antenna-mode ?
  1x1      Use only antenna A to receive and transmit
  1xALL    Transmit on antenna A, receive on all antennas
  2x2      Use antenna A and C for both transmit and receive
  3x3      Use antenna A, B and C for both transmit and receive
  default  Use default antenna setting #antenna-mode 2x2 #com wr
Assuming the AP is on a recent firmware version. 

Regards,

Chris

Thanks. Is this configuration setting also available on the GUI?

The changes can be made from GUI only on APs accessed via the Enterprise UI. They are not available for APs accessed via Swift UI (also called Express UI)

Assuming you are accessing the AP using the Enterprise UI:

Go to Configuration > Devices > Device Overrides > Double click on the AP in the list > Expand Interface > Radios > Double click on the Radio you'd like to hide it on for example Radio 1 > Radio settings > Antenna Mode > select your choice from the drop down menu > Ok > Exit > Commit and Save. 

The above is configured as an override; however, it can also be configured as a system profile setting should you have multiple APs adopted onto a controller or a virtual controller. 

I hope this helps,

Regards,

Chris

Hello Lan

There is the screenshot from GUI at Radio Setting tab.
You could set the number of transmit and receive antennas from Antenna Mode.  



Best regards,

No Tuan

The default setting is dynamic based on the Access Point model deployed and its transmit power settings.

Thanks.
