For those Android Oreo users whom are experiencing wifi problems, try the following steps:
1 – With both the 2.4GHz and 5GHz wifi enabled on your router (not smart connect) save both the 2.4 GHz and 5 GHz wifi connections onto your Android Oreo device. Connect to each network, one at a time and enter the password and make sure the connection works. Then best to stay on the 5g connection for now.
2 – Then on your Android Oreo device, go into settings, and disable Bluetooth Scanning.
It has been reported that the bluetooth scanning function on Oreo interferes with the 2.4 GHz scanning on the Orio device. This in turn has the effect of making the device unable to switch from 5 GHz to 2.4 GHz when the 5 GHz signal is too weak.
This is not an ASUS only issue, but is common amongst other Router manufactures, but I am leaning towards it being Broadcom based, as not reading any issues of other wifi chipset manufactures having same problem’s in there routers
