What are some extra steps I can take to secure my network?

DD-WRT open source firmware removes many firmware vulnerabilities and backdoor access issues that may cause problems in stock firmware. DD-WRT is also updated more frequently than stock firmware, so be sure to always check with the FlashRouter support team to see which DD-WRT build we recommend for the highest level of security for your router at any time.

Aside from avoiding common issues and flaws with stock firmware, DD-WRT give you more control over the firmware settings and allows you to take some extra steps to really lock down your network security. In this article we highlight additional options for WiFi network security and also preventative measures for remote execution attacks.
