Having an issue where some end devices are unable to view an SSID, and suspect it's due to their compatibility with the SSID being broadcast out of the 802.11ax radio.
These devices can only operate at 2.4GHz (group policy/compatibility), so disabling the slot0 radio (dual-band) also stops those clients who are working as expected from operating all together.
Is there is a way to remove the 802.11ax functionality from the 9120 AP? I can see the 9115 and 9117 have both a 5 GHZ and 2.4 GHz antenna, but the 9120 only has a 5GHz and a "flexible" antenna, offering both (so 802.11ax).
Flexible radio (either on 2.4 GHz or on 5 GHz)
2.4 GHz, peak gain 4 dBi, internal antenna, omnidirectional in azimuth
5 GHz, peak gain 5 dBi, internal antenna, omnidirectional in azimuth
Dedicated 5-GHz radio
5 GHz, peak gain 4 dBi, internal antenna, omnidirectional in azimuth
"
I've created a new WLAN with 802.11b and 802.11g only set, but I believe these are still being broadcast out the dual-band radio (802.11ax) on slot0 on the 9120, correct?
Solved! Go to Solution.

Is Flexible Radio Assignment (FRA) enabled?
I think you're confusing FRA and 802.11ax.
If you want to individually disable FRA, then the AP can be configured for the 2.4 Ghz to be client-serving.

In GUI:
Wireless > 802.11 a/n/ac/ax > High Throughput (802.11 n/ac/ax) > 11 ax mode [uncheck]
Repeat same for 802.11 b/g/n/ax

while this was solved by turning of .ax support from one or both band segments, Potentially client driver updates might also work for a mixed environment.
