My router dropped once since that post. Changed the Channel Bandwidth from 20 / 40 / 80 MHZ to 40 MHZ and the control channel from Auto to 157.
Has not dropped in 3 days so far.
Think I figured it out. Go to Wireless -> Professional -> and select the 5Ghz band.
Disable all of the following:
You can do the same for the 2.4Ghz band. Mine appears to be working now.
See this post where I saw this suggestion...
So before returning it, I followed these instructions and manually flashed the latest firmware: 3.0.0.4.386_45934. Followed the instructions to reboot and set it up.
Once I got it set up, turned off the 2.4GHz radio so it only had the 5GHz. Added 4 devices to this and it worked about 5-6 hours...
Recently purchased the AX68U. It is a dud. Will most likely return it.

I started off with separate SSIDs and the problem started there so not a Smart Connect issue.
While I am somewhat technically savvy, I have no interest in becoming a networking engineer looking through logs and diagnosing problems. Just looking for a modern WiFi router, as my current router is...
If that is the case, I will just return. I was trying to replace an old Cisco EA6500 which has been pretty much rock solid for the last 7 years and this new 2021 Asus technology appears to be just garbage.
Unfortunately using channel 36 and bandwidth 80 did not resolve this problem. All my 5 GHz devices switched over to 2.4GHz as the network dropped again.
Any other suggestions or should I just return?
I switched it over to channel 36 and bandwidth 80. Appears that range is a bit less now for 5GHz as some of the further devices are connecting via 2.4GHz instead of 5 GHz. Will test to see if this improves anything.
What is the rationale for this channel and bandwidth?
Hi, I purchased a ASUS AX68U last week and am having a problem with the 5GHz band disappearing and all connections dropping. Initially set it up with separate 2.4GHz and 5GHz bands with some devices connected to each band. All of a sudden the 5 GHz disappears and no devices can connect to it...
