El Capitan - Losing internet connection every 20/30 minutes MBP Early 2015 keep losing internet connection! Still connected to the router but no data in or out, can't even access router settings.

If I toggle wifi on and off it will be good for 20/30 minutes and then same cycle. What should I do, what is the problem?

I know the same exact question is out there but nothing is working!

I have tried:


Remove airport/network configs
sudo ifconfig awdl0 down
5gHz band
Removed network
Replaced modem
Cleared DNS cache
Removed proxies in network settings
Disabled "wake for wi-fi network access


Don't know what else to do... Haven't done any PRAM or SMC resets.
If you create a new user account in macOS and that solves the problem, then you have a configuration issue or an app or daemon misbehaving.

If that does not solve the problem, based on the steps you've taken already, check to make sure your router/access point has its firmware up to date. 

If it's up to date, you might try resetting it to its defaults.
