Example URL:
When the problem happens all URL's are a problem

Steps to reproduce the problem:
1. The issue happens when using Motorolla (ARRIS) sbg6782-ac.
2. 
3. 

What is the expected behavior?
DNS will not resolve no matter how I change my DNS servers. Resetting the connection will often allow DNS to resolve for a short time.

What went wrong?
I suspect my Motorolla (ARRIS) sbg6782-ac is the issue.  The issue happens on WiFi and when connected via a network cable. It happens only to my Chromebooks. My Android devices and Windows 10 PC's do not have the issue at all.

Did this work before? N/A 

Chrome version: 63.0.3239.116  Channel: stable
OS Version: 10032.75.0
Flash Version: 28.0.0.126

When I connect a different WiFi router (TRENDnet N150) via network cable to my Motorolla (ARRIS) sbg6782-ac the DNS issue goes away when connected to the TRENDnet N150.
