$50 · DLink DIR-868L Router

Used DIR-868L router. Served me well but redundant now. Includes router, power adaptor, quick install card, and network connection info (default password etc). Connects via D-Link app which allows you to control features such as website access (e.g. banning access to inappropriate websites) and time control (e.g. shutting down access at bedtime for specific users). Reset to factory settings, should just be a case of following the app settings to get it up and running. Can also be used as a bridge apparently.
