I am having the same problem. I spoke to tech support and they ended up sending out a new router. had it for a few days, but I am still having the same issue. I can change the 2.4g network's channel and it will work for a bit, but then it will go out. Perhaps a firmware issue?

I'm having the same problem. 

I've tried:

1. Restarting modem (multiple times)

2. Restarting devices

3. Multiple devices

4. Changing channel on modem setttings

5. Resetting the modem and changing the name and passwords

 

Some have resulted in a temporary fix but nothing permanent.  I'm thinking TP-Link has some major issue and there aren't enough of us complaining for them to do a firmware update for it.

 

I'm thinking of returning it and not getting another TP-Link product.

I've found a solution to save my 2.4 ghz network: turn off the 5ghz network.

 

I know it's bullcrap, but I need 2.4 for my older devices that can't run 5ghz.  Plus I want the distance provided by the 2.4.

 

My previous fixes didn't work.  Thanks a lot TP-Link!
