I’ve run Synology since they got into the router game and I unfortunately I cannot recommend them. I adore their NASes and they are rock solid but the routers aren’t tested properly in my opinion. I live in a VERY Wi-Fi contested area and it really affects their hand-off between nodes in their mesh, which means a device often stays connected to the wrong node up to a point where there’s simply no connection. I thought it was a 1st gen problem but after upgrading to their 2nd gen systems it hasn’t solved the problem.
I’m moving to another router/mesh system now, which I’ve tested and it works considerably better.
