The described technology is generally directed towards adjusting communication channels. According to an embodiment, a system can comprise a memory that can store computer executable components, and a processor that can execute the computer executable components stored in the memory. The computer executable components can comprise a network metric monitor to monitor a network metric of a communication channel between a first device and a second device, a change in performance of the communication channel based on the network metric. The computer executable components further comprise a channel rating component to adjust a rating of the network connection based on the change in performance of the network connection, resulting in an adjusted rating. The computer executable components further comprise a link controller to adjust the communication channel based on the rating, resulting in an adjusted communication channel.
