Need more network ports for your HP Minis but don't want to spend a lot of money on a new switch? Using OpenWrt, transform an old router into a modern managed switch. We go step by step how to flash the OpenWrt firmware and configure it for hardline network connections as well as a remote access point via WiFi.
