@dubhead , yeah, hopefully Asus will change the way they release their firmware -- they should list previous firmware versions in the download page.

Thanks @jzchen !

HI @Saltgrass , I haven't changed anything. It suddenly was not working anymore after updating to the latest firmware.

Thanks for this one @jzchen ! I'' try to flash it tonight when the router's network traffic is less.

Thanks @jzchen for the suggestion. Hmm, I haven't tried using Merlin but based on what the document mentioned, the current Asus settings are retained like all my AiMesh configurations are intact, is that true?
