Netgear02 Dropping.

I purchased Nighthawk CAX30 and had issues with Netgear02 dropping. Some of my devices in my home use Netgear02. This is very frustrating specially when Nighthawk is new. My two years expired and decided to go solo. I was able to set the router to a point that 02 dropped maybe once every 4 moths. Now that I decided to purchase support for two more years, all of a sudden I'm experiencing issues with my 02. This makes me believe that its all a part of buying support and making us think that we need them.
