For most homes and small businesses, I prefer to install the Synology RT2600AC router and if needed, expand the WiFi coverage with one or more MR2200AC mesh devices. These are very stable and secure routers. Before installation, I spend about an hour configuring the units and make sure the firmware and apps are updated and are set to update automatically. This is an important security feature that is missing from most routers witch are mostly forgotten en left at an old firmware while critical patches are available for these internet gateways!
I enable remote control so I can remotely manage the network without having to go on-site.
Another cool feature is to send an email alert to the client and me if there is a problem. It even alerts you when the internet connection has gone offline. Having a large number of routers in Santa Barbara notifying me about outages puts me ahead of Cox cable. I always provide my clients with all the information needed to manage their network. When possible, I put a label on the router with the admin info. And I always use a red ethernet cable between the modem and the router to indicate its importance and making troubleshooting by phone easier.
