G3200 Extender loses connection to internet

Hi. I have the G3100 router with 2 G3200 extenders (one on each floor). The 2 extenders are connected via coaxial cables. They both setup correctly. I’ve noticed that the 2nd floor extender will lose connection to the internet, the light turns solid yellow. A check of the other 2 show a solid white light. Restarting the extender seems to fix. It also will happen to the 1st floor extender on occasion but not as frequent as the 2nd floor. Any idea why this would happen?

What is in the Log of G3100? Do you see any DHCP-related problems?

Do you see something like DHCP DISCOVER, DHCP OFFER, DISCOVER, OFFER... loop? Please report back here anything abnormal you see in the log.

I looked at the log but I can't make heads or tails of it. Novice at best. I tried to search for the terms you listed below but it did not come up with anything.

I understand your technical limitation. For us to help you resolving the root cause of Internet Disconnection, we need more information other than what is not working and rebooting.

Besides those terms, what exactly should I be looking for. I tried to copy the log into the post but it says it's exceeded the character limit.

Here's some info from the log that I found around the time it lost connection. Hope this helps.
