Cake QOS R7800, expectations

Can anyone help with this, where as my 5ghz was going down before now it seems to be my 2.4ghz, I can’t get WiFi stability when using OpenWRT;

I have moved to hnyman OpenWrt 18.06-SNAPSHOT r7653-939fa07b04

Are there known stability issues? I find that my 5Ghz doesn't want to come up half of the time?
