The number of smart home devices and their applications are increasing with little regard to the maximum capacity of the networks which are supposed to host such devices. We explore how well various consumer-grade routers perform when a multitude of IoT devices are connected and several video streams are active at once. Evaluation results demonstrate entry-level routers are not capable of handling the workload produced by IoT devices. Routers that support Multi-Input Multiple Output (MIMO) technology, and multiband routers are recommended to compensate for these devices.
