Lag is essentially delay on the Internet. With the Netduma you have all the tools needed to diagnose and reduce the 4 points of delay:

  • Local Congestion
  • Distance
  • Remote Congestion
  • Local misconfiguration or error


Before you starting diagnosing and reducing lag please make sure you are lagging in the first place.


The first step is to check the gaming services are fully operational. If not it can severely impact your online experience. Unfortunately if they are not there is nothing you can do other than wait.


Step A


We need to determine if it is a signal or a configuration problem. You can do this on the Netduma by selecting Internet Diagnosis on the main menu and clicking “Run Test”. If the results are below “OK” you likely have an issue with your Internet. I'd recommend you call your local ISP and use the information in the “Details” Tab to let them know there is an issue.


If the results are positive, jump to Step B.


Step B


We now must determine if it's other people in your home creating lag. To begin this task, please select Network Monitor on the Netduma main menu. You'll see two graphs illustrating your current network usage.


The utilisation bars above the graph show how much of your connection is being used. If either of them ever goes above 70%, then this means other people at your home could be making you lag. Please see the Congestion control manual to combat this.


Step C


If the Geo-filter is supported for your game, you can use it to prevent the Netduma from connecting to players who are too far away. This eliminates cause number 2 of the delay. See the host filtering manual.


Step D


After following steps A, B and C you should have control over Congestion, Distance and Errors - the main causes of lag. So all that is left is cause number 3. That is connecting to other players or hosts with a bad connection. The solution here is simple: use the allow & deny feature to prevent the Netduma from connecting to them. See the Deny & Allow manual.
