I see that my router is only allowing 16 devices at the max, in both 2.4GHZ gn 5GHZ, together(Combined). Any additional devices, router is saying, no internet.

A little more info about your system is needed. 

1. what modem/gateway do you have? 

2. when did this start? 

3. have you tried a simple factory reset and reinstall (don't use a backup to install)?
