Cannot change preamble to short

[NGuser76]

Brand new RAX30 router. Cannot change preamble setting to short. After changing and hitting apply just goes back to long setting. Factory reset twice with same result. Latest firmware as of now installed V1.0.10.94_3.  Seen other RAX series routers in community with same issue.

This is a know bug in the firmware. I do not know if there's a fix in the work.

Why do you want/need to do that?

Most likely because it increases speed by a tiny bit due to using shorter checksums thus less computation too.

I live in an apartment building and here it's full of WiFi "noise" (many APs close-by) so I keep long preamble for better stability.
