@amelluk I think you need 1.0.6 firmware for the EAP650.  It was released a few weeks ago but then pulled for an unknown reason.  A few people posted a thread of about getting stuck in a bootloop after updating until they reset it so maybe that is why they pulled it.  I had no such issue though.  You can still find the file on their site if you understand their URL path structure of their zip files if you want to try it.

  @mackworth 1.0.6 is back online since a few days. But still have bugs inside.

There is a new beta which addresses IPv6 and TCP VLAN issues mentioned within this forums.

Some say it is working now, others say, they still have bugs. So let's wait and see.

But yes - 1.0.6 and actual beta let you scan power optimisation. But at my side I have to turn of 6GHz within settings (it still shows up even when my AP does not support it).

  @Spryde where is 1.0.6? I cannot find it. Only thing I can find is a 1.0.0 beta with a late build date. 

I have 3 Omada EAPs:

1 x EAP 650 that has updated to 106 recently. (1.0.6 Build 20220921 Rel. 73404)

2 x EAP 653 (1.0.1 Build 20220524 Rel. 60447)

I was under impression that EAP653 is pretty much the same access point that EAP650 but without a power supply, however both of my EAP-653 are still running on their original firmware version and there is no update available for these APs. 

Of course both 653s fail power adjustment since the old firmware does not support this feature.

My question is, how can I get an update for my EAP-653 and can the new 1.0.6 firmware from the 650 be used on 653?
