Anyone have an idea if the fixes will be mainlined into the stock firmware from Asus? I think I've been running into this issue for months now and I finally had the right combination of keywords on Google + SEO to have this thread show up. I had some mixed results installing Merlin in the past (likely defect hardware though) and want to minimize the chances of running into issues again, especially if I will have to recreate my current configuration from scratch. I switched to the highest frequency band with 20/40/80MHz kind of in the vain hope that this reduces the chances of reproducing the issue but I don't see why that would be the case.
I dirty flashed my AX68Us to merlin from stock Asus firmware and didn't have to change a thing. It kept my configuration exactly the way I had it.
