Who I have the same questioned this topic

We have used a Verizon Wireless MiFi Jetpack for years for our home internet service. We recently added a 'cantena' and router for the installed Verzon Wireless Internet. We currently have both wifi's active.

As of yesterday, I am unable to access certain websites through our new router-based wifi. Namely Nest.com, Amazon.com, and oddly enough, verizonwireless.com. I am asking this question via our old wifi and the MiFi Jetpack, which still works fine. I can use Google just fine on the new wifi.

Where do I begin to fix this problem?
