I was so impressed by Synology's NAS products that I decided to checkout their routers when finally upgrading from my Apple Airport this year.
I went with the WRX560 and so far I'm really happy with it.
The SRM software is on par with the NAS DSM software, which is to say its easy to use and looks great.
I created several wifi networks, including one just for home IOT stuffs, and even assigned one of the back ethernet ports to same network for my wired IOT devices.
So far I'm happy ...
