802.11r and mesh no longer possible?

[F4FXL]

Hi All,

I am in the process of upgrading my old TP-Link Archer C5 v1 to OpenWRT 21 to 23.05.2
My setup consists of 3 Archer C5 acting as dumb APs. All firewall and routing functionalities have been turned off.
All 3 APs are inside a 5GHz 802.11s mesh and also provide an Access Point. The Access Point was configured with 802.11r on older OpenWRT.
I have built my own image using wpad-mesh-openssl, only to find out that this does not support 802.11r. None of the "mesh" wpad seem to support 802.11r.
The reason I choosed OpenSSL wpad is because I wanted to turn on speed optimization in the OpenSSL build option.
Now the question: how can I get openssl with 802.11s and 802.11r support?

wpad-mesh-openssl

Try wpad-openssl

Just rebuilt the image with wpad-openssl, no 802.11r ....

with wpad-openssl, no 802.11r .

Oh well, worth a try. I am using wpad-mbedtls here (on completely different hardware) and it seems ok. Maybe try that...

BTW - How do you know 802.11r is not working?

802.11r options are not present in LUCI. Hence my assumption.
On version 21.x I was using wpad-wolfssl which gave the 802.11r options. The reason I wanted to try openssl are the speed optimisation during build which other SSL libs since to lack (at least in menuconfig).

Ok problem solved.
I went back to mbedtls and then I noticed 802.11r options have moved from "Security" tab to their own tab.... Maybe the tab was already there when using openssl and I did not notice it, in this case this a huge PEBKAC on my side.
Nevertheless, wpad-mbedtls causes less CPU load then wpad-openssl which I did not expect. I will stick to that for now. I need to upgrade my hardware at some point though, 300MBits is the best I can reach with the old Archer C5....
