How To Fix Buffer Bloat with DD-WRT


If you are an active Internet user (and who isn’t these days), you may be experiencing the active frustration of learning how to deal with buffering. Buffering, of course, being the process of storing data in a buffer while it is being processed.

At any rate, most users are familiar with buffering, but not buffer bloat- the massive drag on Internet performance created by previous attempts to make the network work better. The more time a router spends buffering data, the more buffer bloat is created, and the overall performance of the network becomes gradually worse. However, a solution is available. FlashRouters will show you how to fix Buffer Bloat with a DD-WRT router.

Am I Experiencing Buffer Bloat?

If one wants to learn how to fix Buffer Bloat, one should first determine if their router is experiencing it. Consequently, here is an easy to follow step-by-step for determining if your router is bloated:

  1. The first step requires you run a Ping Test to If you are unsure on how to run a ping test, here is a user-friendly guide from iiiNet.
  2. Look at the ping test. You should see a series of lines appearing between 20-100 milliseconds.
  3. In addition to the Ping Test to Google, run a Speed Test.
  4.  Watch the two tests side by side.
  5. If the times jump up while you are uploading or downloading content, your router is bloated.

How To Fix Buffer Bloat With A DD-WRT Router

If your router is bloated, do not fear. There is hope! You can minimize Buffer Bloat by flashing your router with DD-WRT firmware. However, you will only be able to prevent future Buffer Bloat with this solution. On the other side of things, you can purchase a newly flashed, supported, and warranty-equipped DD-WRT router from FlashRouters. With a new DD-WRT router, you can secure the performance of your router by making sure it is never affected by Buffer Bloat.


All things considered, the Netgear Nighthawk R7800 X4S is a fantastic choice for anyone looking to improve Buffer Bloat. Moreover, the R7800 uses a super-powerful 1.7 GHz Broadcom processor. The processor of a router, in many ways, serves as the engine. A powerful engine with withstand more use compared to a weak engine and the same goes with a processor. At any rate, a high-end processor will certainly provide a defense against Buffer Bloat. As will DD-WRT.


Above, you can see the Quality of Service settings for DD-WRT. Setting the maximum download and upload speeds below the rated speed of your ISP will certainly help limit Buffer Bloat. There will be a sacrifice of speed but this limitation will offer a much better performance for not only the router but the overall network.
