WPA3 via Unifi APs
-
I guess I'll start at the basics. Unwind any misconceptions before moving forward.

Just updated my UAP-AC-Pro's to 5.53.1.12737 which showed up available this morning.
Just FYI for those looking. I assume one would need this for WPA3 capabilities..
-
The previous firmware supported it, 5.53.1 was just putting them all on the same version again for the different gens of their AP.

There was a bug in the previous version..
Some printers were not connecting with WPA2/WPA3 transitional - PMF optional..Now it's fixed.. So you can have WPA2 only devices connected to a WPA3 BSSID without problems now.. At least nanoHD.. I guess this release is going to be an official release

BTW, I finally solved the wrong date/time in the controller.
Thanks to an user in the Ubnt forum, found out that the controller is not using the system time, it's using the Java time, which is outdated..
In case you are facing this problem in the controller, follows below how to fix:
Update JAVA TZ time Java SE Timezone Updater 2.3.2 https://www.oracle.com/java/technologies/javase-tzupdater-downloads.html java -jar tzupdater.jar --version sudo systemctl stop unifi.service sudo java -jar tzupdater.jar -l java -jar tzupdater.jar --version sudo systemctl start unifi.service -
Did you manage to get WPA3 Personal working with a NanoHD or FlexHD? I just updated my controller to 6.1.54 and am struggling to get it working with a Macbook. I tried enabling it but the Macbook didn't seem to make a WPA3 connection. I read this thread which was a bit over my head, but the impression I got is that with MTK models like NanoHD/FlexHD WPA3 may not be working???
BTW I figure you must know but just in case any reading this doesn't.... re: seeing if clients are using WPA2/WPA3.... on Mac you can just option-click the WiFi menubar icon and it'll tell you all the connection info.

@occamsrazor It works "fine" on a nanoHD. The issue, as pointed out, is clients that do not support WPA3. In my case it's around clients that do not support PMFs that are required with WPA3-Enterprise.
As to the status on a MacOS, there is a bug (I reported it) that if a you connect WPA2-Enterprise with mandatory PMF the Mac will indicate it's a WPA3-Enterprise connection in error.
To me, this is a question of what do you really want or require. Meaning does WPA3 buy you anything that is worth the effort. You'll have to answer that for yourself. Any weakness is only a potential problem once some client is authenticated on a WLAN. My home network is not a zero trust network (IoT devices are walled off and given Internet access only via a WLAN just for them) so it's not a big deal to me.
I want to encourage anyone who is thinking about updating their controller to the 6.1.x train be absolutely sure you have a fallback plan. Backup your Unifi config and know how to downgrade the controller.

I has helping Glenn to fix this problem:
https://community.ui.com/questions/Samsung-printer-connectivity-issue/e9b782b9-a40b-48cb-b43c-0b0d35716f0e
He asked me to test a firmware in the nanoHD, and with it I was able to connect my printers to the WPA2/WPA3 transitional BSSID, with PMF optional.
My Galaxy S10 detects the network as a WPA2/WPA3 network, but I didn't perform packet captures to confirm if my phone is indeed using the WPA3..
Try to "forget" the network in the Macbook, and connect again.
More info about it in this topic:https://community.ui.com/releases/UniFi-Network-Controller-6-1-51/9124593a-1d5e-40f1-a3a7-ab62862e1fce#comment/d6af6798-d8dd-4ecf-8399-05e2cd487409

I really have no need for WPA3 in terms of security, I just like to try new things and understand how they do, or don't work. I was interested by improvements in roaming supposedly in WPA3, though the WPA3 specific fast-roaming seems unsupported by NanoHD at least at this time.

Do you mean it's only working in a non-public firmware? My NanoHDs are on 5.53.1.12737

I just tried that but it didn't seem to help, Mac menubar and Wifi settings still report it as WPA2-PSK only. Is there a minimum MacOS for WPA3? My Macbook is still running Mojave 10.14.6....
My Wireless Networks settings are:
Security: WPA Personal
WPA3: Support WPA3 connections
WPA3 Transition Mode: Support WPA2 connections on same SSID
Fast Roaming: Enable fast roaming
WPA3 specific Fast Roaming: OFF (If I enable it says my NanoHDs do not support this feature)
PMF: OptionalI notice that the "WPA Mode" setting directly beneath the PMF setting is greyed out (unselectable) and says "WPA2 only"

The FW 5.53.1 probably has the fixes present in the non-public firmware, so it should be working for you. At least my printers are connecting with this firmware, no confirmation from Ubnt that indeed the fixes are present in it.. It's woking so I'm making an assumption that it's present.

I don't think so, you see, WPA2/WPA3 transitional with PMF optional, should be fully compatible with WPA2 only devices, if this problem is happening to you, report it asap so they can fix it in the next release.

PMF: OptionalI tested using the same settings..

I may have been confusing. With Unifi set to WPA3 Transition the MacBook still did connect fine, only at WPA2 not WPA3.
According to this article WPA3 support was only introduced in Catalina, not Mojave, so that explains it..."Try to manually join a Wi-Fi network in Catalina on many Macs and you’ll see that WPA3, the new Wi-Fi encryption protocol, has joined the (still default WPA2) and the (old, insecure) WEP and WPA as a security option.
But unlike iOS 13 and iPadOS 13, which support WPA3 universally across all supported devices, not every Catalina Mac can use WPA3. Older 2012-era Macs with 802.11n adapters still top out at WPA2."
https://arstechnica.com/gadgets/2019/10/macos-10-15-catalina-the-ars-technica-review/12/I just tried with my new M1 Mac Mini running Big Sur (which only usually ever uses ethernet) and it connected immediately on WPA3 without even needing to forget the network... so seems it is the lack of WPA3 connection is just because Mojave does not support.
It's a shame Unifi doesn't expose the WPA version in the Clients list. I can't install that developer profile on my iPhone as it's a company-owned phone.

Exactly, people are asking for this feature.. Controller should be providing this info in the clients list...

Not sure if there was a request already, searching that forum is so hard, but I created a new one:

Not holding my breath.

@occamsrazor I up-voted your post on the Ubiquiti forum linked above. Others should do the same if they want Ubiquiti to even notice that it exists.

4.3.28.11361 ?? Reason I ask is because non of my devices connected with WPA3 until I upgraded to the later firmware.

What AP are you using?
As you could see I was using old 5.43.24 firmware and was getting wpa3 personal on my iphone.. When connected to ssid set for personal wpa2/3 But that was on pro, lite and lr models - not flex or nano. A enterprise ssid was still showing wpa2-enterprise
They had released a .27 and a .28, but for the pro,lite and lr line, etc. When they jumped to 5.53 - they are all listed on the same firmware version.
edit: I upvoted your post over on the unifi forums as well - its just moronic that what a client is connected at be it wpa2 or 3 is not on the controller.. Installing the profile is a pita, and its only good for like 30 days even. stupid why that needs a specific profile to be given to the user.. Great info there should just be default.. Actual signal strength, specific bssid connected to, etc.
edit: So with the latest firmware 5.53.1.12737, looks like showing that connected with wpa3-enterprise
I had bumped my sons on his flexHD to wpa2/3 personal.. But he had a problem with one of his roku sticks. I will have to try moving back to wpa3, see if I can even just turn off wpa2.. But I doubt some of his stuff, tv and rokus support 3, so will prob have to leave it in transition mode.

I changed the cipher_list from default to HIGH, and then even just called out AES256-SHA256 by editing freeradius.inc - since couldn't find a way to edit that in the freerad gui..
Is this necessary?
Look like there is no option in the FreeRADIUS GUI... -
No - That was me troubleshooting, that turned out to be an issue with no users on my part..
cipherlist is currently back to default
cipher_list = "DEFAULT"
