We tend to take Wi-Fi coverage for granted these days, but it wasn’t always like that, with many consumer routers leaving a lot to be desired. Things like quality of service and mesh capability were features only found on enterprise gear, even if the Wi-Fi routers you owned could technically support these. To improve the feature set of these routers, you could install custom firmware like DD-WRT or OpenWrt, which would give you tons of advanced features that home routers just didn’t have at the time.
