ASUS-AC68R 2.4ghz dropping

[AzNBoY92]

For the past month the 2.4ghz on all devices downstairs(router is upstairs) have lost connection and 15-30 seconds later it will come back, every device gets 4-5 bars downstairs. Now the weird thing is 2.4ghz devices upstairs don't lose connection at all, and the 5ghz devices have always worked fine. What could be the problem? I'm running Merlin's 3.0.0.4_374.39_0, I have tried restoring to stock but still does it.

Sounds like it may simply be an issue with a signal or interference being concentrated in the lower level vs. higher up.

The fact that the upstairs devices don't lose their connection is telling.

Do you have new neighbors or maybe city/utility workers nearby?

It only happens at night is the weird part also, and its happening while Netflix is being streamed on a Smart TV. New neighbors last week but its a military rent out house so I get new neighbors every 6-12 months. No workers nearby. I had a D-Link 655 with no problems and I had a N66U but upgraded.
