How many total devices connected? How many wired, how many WIFI?
I would recommend a more business grade router. Asus is fine for home, but I would recommend a wired router and WIFI access point(s) for a business setting.

For an upgrade from the "home" router segment you can look at Ubiquiti UniFI
