The way DNS works is if the Cox DNS can't resolve a URL, the DNS process will find the 'authoritative' server hosing the domain of said URL. However, when the ad loads, it makes a DNS request of a website. No big whoop because your safe-surfing habits prevent you from clicking it. For example, if you want to control your Sonos with an Android smartphone, Sonos will implicitly trust the smartphone as long as it has an IP address from your home router, which would be a private IP address.īasically, a malicious ad loads on a web page. The vulnerability is called DNS Rebinding and it exploits the 'implicit trust' between all devices on your personal network. One of its many potentially malicious acts is to provide a denial-of-service with Roku. I wouldn't swap anything until Roku patches a new vulnerability with streaming-media devices (Chromecast, Google Home, Roku, Sonos, thermostats). The WiFi modem should be in a vertical position.Īreas to avoid would be near other interference sources (such as microwaves, high powered appliances, 2.4 GHz cordless phones or other wireless devices close to other Wireless Access Points), basements, next to other wireless routers, near metal objects and surfaces against a wall, tucked away in a corner on the floor or behind the furniture, near windows or close to halogen or fluorescent lighting. An elevated location, such as a higher shelf, where laptops have a line of sight view. If you are having difficulty keeping a consistent connection with your Roku devices, you might want to consider the location of the Panoramic WiFi Modem and wireless extenders should be placed in a central location in your home away from interference.įor optimal performance, place the equipment in a central location where the devices will mostly be used.
