Unifi UAP-AC-Pro: Only HT20 and VHT20 available

Hi All,

 

I have about 250 UAP-AC-Pro (and a few old UAP) on my infrastructure accross 30+ sites. we are using HT20 in 2.4GHz and VHT40 in 5GHz.

Lately, we aquired a few more UAP-AC-Pro for one remote site we are expending and when I start setting them, they all offer HT20 (for 2.4GHz) and VHT20 (for 5GHz) only.

Any idea of the root cause of this?

 

Thank you

I presume that this persists even after a factory reset?

Hello @mortem,

 

On what country did you set it?

Maybe your country doesn’t allow it.

I are freshly adopted AP but I can try a reset.

The site is set with country parameter "Japan". I have other sites in Japan and none had this issue.

 

Thanks

Hello @mortem,

 

Please give the UAPs a reset.

What browser are you using?

Have you tried clearning the browser cache?

 

What controller version are you on?

What firmware version do you run on the UAPs?

 

 

Regards,

Glenn R.

Hi,

 

Sorry for late reply, I was busy on other stuffs.

I reset twice the AP and nothing changed.

I tried wih Opera and Chrome browsers and all other AP show the correct settings. Only those 2 have a problem:

Controller version is 5.8.30

AP firmware is 3.9.54.9373

 

Thank you

Hello @mortem,

 

Could you for giggles forget them and adopt them to a different controller?

Unfortunately I will not have that options as they are on a remote site.

Today I deployed 2 new UAP-AC-Pro in another country and both can show HT40 and VHT40, so it means it is not due to my controller.

Hello @mortem,

 

You could try a TFTP recovery...

In my opinion, 2.4ghz should be left at HT20 anyway. 5GHz is a different story, use 40 at least.

Re: Unifi UAP-AC-Pro: Only HT20 and VHT20 available

Hi @AmazedMender16,

Unfortunately those 2 AP are on a remote site a few thousand km far from my location. However I just did (again) on one of them a syswrapper.sh restore-default and the issue still remains.
As said previously, out of almost 300 AP (UAP, UAP-AC-Pro, UAP-HD), only those 2 present this limitation.

Hello @mortem,

 

Well there isn’t much you can do without access to the UAP...
