When I have my WDS network set to use WPA3 or WPA2, re-keying takes the network down for almost 2 minutes. Why? Shouldn't the re-keying happen quickly without loss of service?

You need to provide a LOT more information. Router model and build version would be a great start.

How many times does this happen? It is possible that the first few times are slow but afterwords it speeds up.

Check the build threads for the R7800. I think I saw somebody saying that WDS was not working on it with the new 6.1 kernel. If this is the case, you might consider first taking the R7800 back to r53562 and try again. If still doing it, take the R9000 back to r53562 and try again. I am not using any k6.1 builds on Atheros and my WDS between EA8500s and R7800 is working fine. I have also not tried WPA3 but cannot see that making any difference.

I tried earlier builds with the same result.

Thanks for the links. There are a lot of options in dd-wrt. Not sure if I want to use any of them.


Did you end up enabling this?
