What is DD-WRT, and Why Would I Need One?

[Cover] What is DD-WRT

Whether it be for personal use or organizational efficiency, you would want your routers to work the best. Many of the ones that you buy though aren’t put to their limit, or may not be suited to your interests. Some, for instance, may not allow VPN’s to run by default, or lack extra security controls. Or, you may want to buy a range extender to cover up your required space, but experiencing a dip in internet speeds is common.

What if you didn’t have to buy one and could get an extended coverage area? What if you wanted to enhance the performance of your router, boosting its speed and improving its functionality, thus turning it into a business-class router?

DD-WRT is the answer.

By installing the DD-WRT firmware, you can overcome the inbuilt restrictions of your router’s firmware,  vastly expanding its capabilities and even unlocking some advanced features.

About DD-WRT

DD-WRT, a firmware for wireless routers and access points, is designed to replace the router’s original firmware with custom firmware – helping you get access to additional features. The firmware, launched in 2005 by a team based in Dresden, Germany is so popular that some companies even ship their routers pre-installed with DD_WRT.

Every router that you buy has a firmware.

The firmware decides what your router’s capabilities are, even if its in-built abilities are more. Think of it as jailbreaking your phone, except that this one’s legal. You can use the in-built hardware acceleration drivers to have your router perform at its full speed. It’s especially useful if you have older routers, as many of these didn’t function according to its capability. The newer ones often fare better on their own, and installing DD-WRT may not make much of a difference.

That being said, the preset firmware of a router can limit its true potential, and you can unlock it by erasing the original firmware and installing DD-WRT in its stead. Do know though that there is no customized support for this firmware, so you need to know how routers work before you try your hands on it.
