If you own a router on that list, simply click on its model name above and you’ll be taken to its product page where a link to the latest firmware download is available. Need help installing the firmware? Asus has a helpful FAQ(Opens in a new window) to guide you through the process.

Asus also recommends creating separate passwords for your wireless network and router-administration page, and if you router supports it, enable Asus AiProtection (details available in your router’s user manual).

If you opt not to install this critical firmware update, Asus strongly recommends, “disabling services accessible from the WAN side to avoid potential unwanted intrusions. These services include remote access from WAN, port forwarding, DDNS, VPN server, DMZ, port trigger.” It’s much easier to install the firmware update and close the security holes.
