I recently bought a SmartThings device from Samsung to automate some actions in my house. After some time, The Google Nest router started to drop the internet connection. None of my devices e.g laptop, smart switches, cell phones were able to access the internet. When I did a Tracert in windows, the ping reached the external IP of the Google Nest router and nothing beyond that point (WAN IP). The solution is to disconnect the SmatThings and disconnect the Google Nest router from the power and connect it again. If I try to connect the SmartThings again, after a couple of minutes I lost connectivity again. 

I thought it could be the device, so, I bought a Raspberry Pi and installed Home Assistant. It was working for 3 to 5 days until the same thing started happening.
In order to make some additional tests I bought a small HUB of 6 ports and I connected it to the LAN port of the Google Nest router and the Raspberry Pi to the HUB. Same result.
If I disconnect the Google Nest router from the modem and I connect a computer, everything works fine. That is how I know that the problem is with the router.

Google Nest is not able to reconnect (Nor the cable or wifi) unless I disconnect it from the power and connect it again.
