Having the error “Disconnected due to traminission error; status: VIGOROUS” popping up when playing Modern Warfare? You’re definitely not alone! This occurs due to a connection problem. But your corrupted game files may also be the culprit.
Before following the troubleshooting guide, we would like to mention that if you have Modern Warfare installed on an external drive, move it to your system’s main drive. Although it seems to be irrelevant, give it a shot as some gamers found that it helped. However, if you can’t see any difference, try these fixes:
- Repair your game files
- Update your network adapter driver
- Change your DNS settings
- Reinstall shaders
- Disable antivirus software
1. Repair your game files
Repair game files on Blizzard launcher
1) Open the Battle.net desktop app.
2) Click your game title. Then click on the cogwheel icon and select Scan and Repair from the list.
3) Click Begin Scan. Then you need to wait for the repair to finish.
Verify integrity of game files on Steam
1) Open your Steam client.
2) Under LIBRARY, right-click your game title and select Properties.
3) Select the LOCAL FILES tab and click on the VERIFY INTEGRITY OF GAME FILES… tab.
If repairing game files didn’t help you fix the issue, the problem might be from your side. Before tweaking any settings, we suggest you restart your router or modem if you haven’t done this in a while. This can work like magic. However, if you’re not able to see any differences, try the next fix below.
2. Update your network adapter driver
When you keep disconnected from Modern Warfare, it’s high time you troubleshoot your network. If you’re using a wireless connection, switch to the wired connection. However, if you have to use a wireless network, there are other ways to make sure that you have a better internet connection. One of the steps you can take is to check if your network adapter driver is outdated or misconfigured, which can cause connection problems. To fix it, you need to update your network adapter driver.
You can manually update your network adapter driver by going to the manufacturer’s official website to download and install the correct network driver for your system.
If you don’t have the time, patience or computer skills to update your audio driver manually, you can, instead, do it automatically with Driver Easy. Driver Easy will automatically recognize your system and find the correct drivers for your exact device, and your Windows version, and it will download and install them correctly:
Here’s how to update drivers with Driver Easy:
1) Download and install Driver Easy.
2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
3) Click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system.
(This requires the Pro version which comes with full support and a 30-day money-back guarantee. You’ll be prompted to upgrade when you click Update All. If you don’t want to upgrade to the Pro version, you can also update your drivers with the FREE version. All you need to do is to download them one at a time and manually install them.)
After updating your drivers, restart your PC and check if your problem persists.
3. Change your DNS settings
The quality of the DNS server supplied by your ISP is, actually, unknown. But switching to a third-party DNS service such as Google Public DNS may speed your internet activity. Here’s how:
1) On your keyboard, press the Windows + keys simultaneously to open the Run dialog box.
2) Type control and then press Enter on your keyboard to open the Control Panel.
3) Click Network and Internet. (Note: make sure you view the Control Panel by Category.)
4) Click Network and Sharing Center.
5) Click on your Connections, whether it’s Ethernet, Wifi, or others.
6) Click Properties.
7) When the Properties window opens, click Internet Protocol Version 4 (TCP /IPv4) > Properties.
8) Click Use the following DNS server addresses:
For Preferred DNS server, type 220.127.116.11
For Alternate DNS server, type 18.104.22.168
Check the box next to Validate settings upon exit and then click OK to confirm the changes.
After applying the changes, launch Modern Warfare to check if this action did the trick.
4. Reinstall shaders
Shaders in Modern Warfare are installed for optimization. But there are circumstances that something’s going wrong with the installation. In this situation, reinstalling shaders can solve the problems you’re having with the game. Follow the instructions below to do this:
1) Boot up your game and click Options at the bottom left corner.
2) Select the GRAPHICS tab. Scroll down and find Restart Shaders Installation.
3) Click RESTART.
This will clear the cache and it will automatically reinstall the shaders. Once it’s finished, play Modern Warfare and you should be able to enjoy the gameplay without getting the transmission error.
5. Disable antivirus software
For players who got the message saying Match Started. Loading level… before receiving the transmission error, you need to disable any antivirus software you’ve installed in case they’re in conflict with your Modern Warfare. This worked for some players, so you might want to give it a shot.
To disable antivirus software, simply click on the up arrow icon near the system tray, right-click on the program, and choose the option to disable or exit the program. Once you’ve done this, play Modern Warfare and test if the message is still popping up.
For further troubleshooting, you can manually add Modern Warfare to the list of bypassing Windows firewall:
1) In the Search box, type windows firewall and click Windows Defender Firewall from the results.
2) From the left panel, click Allow an app or feature through Windows Defender Firewall.
3) Now you need to scroll down until you can find Call of Duty: Modern Warfare.
If your game isn’t on the list, take these steps:
1) Click on Change settings > Allow another app….
2) Your File Explorer is now opening. Then you can navigate to the drive on which you save your game.
3) Click Program Files > Call of Duty Modern Warfare.
4) Click ModernWarfare.exe and then click Open.
5) Click Call of Duty: Modern Warfare > Add.
Now play Modern Warfare and you should be able to enjoy the gameplay without getting the infuriating transmission error.
Still no luck? Then as a last resort, reinstall your game.
