AC68U extremely poor signal strength

[gdee]

Hi,

I recently purchased a ASUS AC68U (rebranded TMO cellspot) router flashed to Merlin 380.63_2. The router performed fine on both the 2.4GHZ and 5GHZ band, the signal was strong (full bars on my S6) for over a week. However, I noticed that the signal strength have degraded significantly tonight without any settings being changed -- it's barely getting half a bar on the 2.4GHz band and less than two bars on the 5GHz band when I'm sitting right next to it. It has gotten to a point where the SSID doesn't even get detected. Anyone have any ideas as to what the heck is causing this behavior or if there's a setting that I should look for? There isn't any new hardware in the house, so I don't think interference is an issue. I've tried toggling each of the band on and off with little effect.

Thanks for any insight.

Have you tried turning the router off and on again?

Multiple times, along with factory resets. no luck.

Does the issue also occur on the official ASUS firmware?

I have yet to try this. I will test this tomorrow to see where the point of failure is.
