DD-WRT definition

DD-WRT is firmware compatible with most router brands that was designed to significantly improve their performance. It expands your router’s capabilities, enables new features, and even provides better speeds. The “DD” stands for Dresden, the city where DD-WRT was created, and “WRT” refers to a wireless router. Upgrading your router’s firmware to DD-WRT is called “flashing” and requires more advanced technical knowledge.

DD-WRT benefits

  • Upgrading to IPv6 support. A lot of routers still don’t support this protocol.
  • A secure firewall. DD-WRT comes with a firewall that will block unauthorized access.
  • Better range. You will be able to increase your Wi-Fi coverage by changing the broadcasting power.
  • Easier network maintenance. With DD-WRT, you will be able to track your router’s performance and troubleshoot issues.
  • Prioritizing bandwidth. DD-WRT allows users to prioritize bandwidth for selected devices. This way, you can give your console more speed if you want to play games online or your TV if you want to stream a movie in 4K without interruption.
  • VPN support. You can’t install VPN on any router you want — but with DD-WRT, you’ll be able to install NordVPN on your router without problems.

DD-WRT drawbacks

  • Not all routers support DD-WRT, so you might have to buy a new one if you want to have more advanced functionalities.
  • Flashing your router is technically challenging, and you run the risk of bricking it. Ruining your router’s firmware could make it unusable to a point where it’s impossible to reset it to factory settings.
  • Messing with your router's firmware could also make your warranty void. So if there’s something wrong with your antenna, the manufacturer might charge you for the repairs.
