Sorry forgot to mention.. AX88U am more interested in getting full duplex upload and download speed on Wifi as I have iPhone 12 Pro and other Wifi 6 devices also I run dual wan setup which needs to function properly
I am running 3.0.0.4.386_41249 which was the last official firmware on Asus site but its pulled off now.
Now how would I know if the RC9 posted here is of greater version means more fixes etc than the one I am currently running. it seems the official firmware numbers are different than beta...
