1. Check Server Status
2. Wired vs Wireless
3. Monitor vs TV
4. Check Console/PC Spec
5. Wired Controller vs Wireless Controller
6. Lower your Base Ping
7. Distance
8. Bandwidth and Local Congestion

1. Check Server Status

Let’s start with a quick and easy check. If your Call of Duty lag problems have only just recently started then there might be a temporary problem with the Xbox Live/PSN servers or even the game servers themselves. So before you go changing anything, let’s check if the issue is even in your control.

What you need to do:

A. Check the status of your online network:

Xbox Live Status
Playstation Network Status
PC (Steam Status)

B. Check the status of the CoD server:

2. Wired vs Wireless

Despite what you may have been told, playing on WiFi is NEVER good for gaming. It can be unstable and cause lag spikes, packet loss, jitter etc – basically it can cause a whole heap of headaches. So if you are serious about reducing Call of Duty lag then playing on a wired connection is an essential step.

What you need to do:

A. If you are playing on Wifi, switch to wired connection. Connect an ethernet cable from your console / PC to your router. If the two are far apart you can buy long ethernet cables (some are as long as 100 metres) to link the two.

If you can’t run a cable between them then look into Powerline adapters, which is a very clever gadget that allows you to use your home’s electrical wiring to transport an ethernet connection around your household. Just plug one end into a plug socket near your router and the other in a socket near your console and you’re good to go. Magic. Check them out:

Powerline Adapters (Amazon US)

B. If you HAVE to play wirelessly then there are a few things you can do to improve it’s reliability:

– Connect to your router’s 2.4GHz frequency instead of 5GHz as it is more stable. All wireless routers have a 2.4GHZ frequency. If you are not sure which frequency you are connected to then check your router’s WiFi settings.

– Use a WiFi analyser to find the least congested channel in your area and then change to that in your router’s WiFi settings. How to find the least congested channel in your area.

A. If you’re already playing wired then you may want to switch out your ethernet cables as they can degrade and become faulty over time.

3. Monitor > TV

CoD runs at 60FPS (‘frames per second’) on consoles & even higher on PCs. If your screen can only display 30FPS then you’re going to have big issues because your screen literally can’t show you the game fast enough.

TVs render much more slowly than monitors, so whilst the idea of a widescreen TV may seem like a good idea, it’s actually one of the biggest mistakes you can make for gaming.

What you need to do:

A. Get a monitor that has, at the very least, a 60Hz refresh rate. It will also need a low response time, 1-2ms is ideal. That’s the delay between the action being executed and being shown on your screen. Here are some recommended monitors:

AOC G2460PF
BenQ XL2411Z
See what our community thinks is the best monitor to use for gaming

B. If you’re only able to use a TV see if it has a ‘Gaming mode’. Monitors usually also have this setting as well.

4. Check Console/PC Spec

If your console’s hard drive is full of games/applications it can run sluggishly. And if you’re playing on a PC then it needs to have a good enough specification in order to handle the game.

What you need to do:

Console

A. Delete some of the games/applications on the hard drive to free up space. On Xbox One in particular if you’re experiencing occasional stuttering then clearing your local saved games can help.

B. Some players have had a great deal of success by replacing the built in hard drives with SSDs (a much faster storage device than traditional hard drives) as they rapidly speed up loading times. A Google search will throw up several options.

PC

A. Check the minimum PC specifications match your rig.

B. If your specs are fine but you’re still experiencing stuttering/lag then you may need to reduce the games graphical settings in order to aim for 60FPS or 30FPS at a minimum. Also stop any intensive background programs as this could be causing stuttering and FPS drops.

5. Wired Controller > Wireless Controller

Did you know playing with a wireless controller can cause input lag? This is the delay between you pressing a button and the console responding. It’s often caused by interference from other wireless devices in the vicinity. CoD Pros don’t use wireless controllers for a reason.

What you need to do:

A. Use a wired controller or if playing on a PC, a wired mouse and keyboard. If you have the budget, you may want to invest in a custom controller e.g. a Scuf.

6. Lower your Base Ping

Your ‘Base Ping’ is a measure of the time it takes for you to reach the nearest Internet server to your home. If you live in a remote area, such as the countryside, your base ping will probably be higher than someone who lives in a city. Base ping matters because it is a delay that you always have when gaming. For example, if you have a base ping of 30ms then your game ping will never be lower than 30ms. So having a high base ping will mean you will always be experiencing some CoD lag.

What you need to do:

A. We recommend using a program called Ping Plotter or utilising the internet diagnostics on the Netduma router to find out the quality of your internet connection. If your base ping is lower than 30ms then you’re fine, otherwise it’s worth contacting your internet service provider to see if they are able to resolve this.

Just remember that there may be nothing they can do if you live in a remote location.

7. Distance

Now we reach the NUMBER ONE cause of Call of Duty lag – the distance from your home to the server / host of your game. Every time you enter a CoD lobby you are connecting to a server or host somewhere in the world. CoD mainly uses dedicated servers for this, which are dotted over the planet. Here is a map of all the dedicated servers in CoD:

Call of Duty Infinite Warfare & Modern Warfare Dedicated Servers indicated on the Netduma Geo-filter map.

Now when you are put on a server far away from you then you will experience CoD lag. It’s just like real life, the further you have to travel the longer it takes. Games are no different.  What’s worse, other players in the game who are located nearer the server will have an advantage over you as their experience will be much more responsive.

So the best way to counter Call of Duty lag is by always playing on servers close to you. And we have the only solution to this massive problem.

What you need to do:

A. The Netduma Geo-filter allows you to set a custom radius around your location and FORCE the game to put you on a local server. This significantly reduces the lag for you and most of the game’s other players. The effect on your game will be very noticeable, with improved response time and fairer gameplay.

B. If you are not able to invest in a Netduma then your next best option is to leave lobbies that are playing particularly poorly. It’s not ideal but hopefully you will have better luck with your next lobby.

8. Bandwidth and Local Congestion

Quick straw poll. Have you, or a friend, ever bragged:

“I’ve just upgraded my Internet speed to X billion megabits per second so I’m now going to be unstoppable online”?

Yes? Thought so. Well you / they have fallen for one of the biggest myths in gaming. High bandwidth speeds do not mean you will have a faster gaming connection.

The truth is games only need a little bandwidth, usually less than 0.5mbps, which most homes have. When it comes to bandwidth speeds what actually matters is congestion on your line, which is caused by other people in your home when they hog the bandwidth, such as streaming an HD film or torrenting. This creates gridlock on your Internet connection and will cause your game to lag significantly.

What you need to do:

A. Most routers have a feature called ‘QoS’, which is designed to prioritise the traffic on your network, e.g. gaming over other applications, and / or eliminate congestion. But most routers do a very poor job of this as they rely on technology that is over very dated and ineffective.

At Netduma we invented a unique algorithm that will totally eliminate all congestion, meaning you can game whilst everyone else uses the Internet as much as they need to. Check out a demo of this in action:

B. If you are not able to invest in a Netduma then your next best option is putting on your best begging face and ask the guilty party to stop hogging all the bandwidth.

9. Port Forwarding/Open NAT

You can have connection issues if the ports required for the game are not open, meaning you don’t have an ‘Open NAT’. A strict or moderate NAT can cause you to be unable to connect to other players online.

NAT Table Console

What you need to do:

A. Check your NAT status. Do this by going to the network settings on your console. For PC players the game itself will tell you this information.

B. If you do not have an open NAT then you should enable ‘UPnP’ enabled on your router. This will automatically open the necessary ports for you. If you still don’t have an open NAT after trying this then then you can manually port forward yourself. Just make sure to do one or the other. Activating both can result in conflicts. See these guides:

10. Internet Service Provider (ISP)

Finally, if you have tried everything else in this guide and you’ve still got Call of Duty lag then it’s likely that poor service from your ISP is the cause. If your ISP is oversubscribed in your area you may experience packet loss during peak times e.g. evenings & weekends, and sometimes errors on your line can cause your connection to the game to be unstable.

What you need to do:

A. If you’ve followed everything in this guide & you’re still experiencing consistent/significant lag then you should consider finding an ISP that has better connectivity options available for your area. A smaller ISP is likely to be under subscribed, thus leading to a better connection and better customer service if required. If you have a Netduma router you can follow this guide to do a test on your network. Alternatively see here for a guide on using Ping Plotter.


That’s the end of our CoD lag fix guide. We hope it has helped you to solve your lag issues. If you are interested in buying a Netduma to crush your lag then you can use code “CoDIW” at checkout for 5% off!
