Fix 1: Check if your PC meets the minimum system requirements for World of Warcraft

This World of Warcraft lagging problem may occur if your system is unable to handle the game. Here we list out the both the minimum requirements and the recommended specifications (if you’re looking for a smoother and more enjoyable gaming experience) specifications for WoW.

All the information below are gathered from the official website of

If you’re not sure whether your PC meets the system requirements for WoW or not, just follow the instructions below to check the basic specs of your PC: 

  1. On your keyboard, press the Windows logo key 
     and R at the same time, then type dxdiag and press Enter.

  2. Under the System tab and you can check the Operating System and Memory information on your PC.

  3. Click the Display tab and you can check what graphics card your PC is using.

You’d probably have to upgrade your hardwares if any of the above-mentioned item fails to meet its minimum requirement.

Fix 2: Power cycle your network devices

Power cycling your network devices (a modem, a router, both, or a combo of both, which will be referred to as the modem router below) can reset and re-establish your Internet connection and hopefully solves the WoW lagging issue.

To do so:

  1. Shut down all the devices connected to the modem router.
  2. Power down and unplug the modem and/or the router.
  3. Allow the modem router to sit for 60 seconds unplugged.
  4. Plug in and turn on the modem and router, and allow them to completely boot up until the front panel connection lights on the modem show a steady connection.
