If you are searching for a match in Call of Duty Warzone, but it seems to take forever, and your ping keeps increasing until it gets to 350ms, then, I got some bad and good news for you.
The bad news is that you are shadowbanned, and, the good news is that you can fix the 350ms ping Warzone ban in under 10 minutes by following the step-by-step instructions you will find below.
The Warzone 350ms ping ban is one of the hardest to fix since, apart from your IP address being blacklisted, there are also one or multiple hardware parts with unique identifiers that are blacklisted as well.
Checking if you are shadowbanned on Warzone is pretty easy. Just queue up like you normally do, and if matchmaking takes a very long time to find a match for you or your ping is 350ms while queueing up or it seems to never find a match on all modes, that means that you are shadowbanned. That’s why you will see people referring to the shadowban as the Warzone 350ms queue ping ban.
To fix the 350ms ping ban while searching for a match on Call of Duty Warzone with 100% success, you should do every step of this guide in the same exact order as shown below and not skip a single one. If you do skip or change the order, you will most likely get banned instantly again!
Download the files, extract them, and move the HWID Bypass folder to your C: drive.
Step 1 – Uninstall Call of Duty Warzone and clear all traces.
The first and most important thing you’ll have to do is to completely uninstall Call of Duty Warzone and the launcher and make sure to clear every single file related to them. We want to ensure that no files are left on the PC that could link you back to the Call of Duty: Warzone 350ms ping ban while searching for a match.
Navigate to the Control Panel and choose the option Programs.
Next, click on Programs & Features option.
Locate Call of Duty Warzone and the launcher, right-click on it, and choose Uninstall.
Now let’s start clearing up all trace files left on your PC. Please double click on each shortcut on the first folder of the files, look for folders/files related to Call of Duty Warzone and the launcher, and delete them.
These are the locations you will find in the shortcuts:
- C:\Program Files (x86)
- C:\Program Files
- + more every time they get updated.
Once you delete everything related to Call of Duty Warzone from all these locations, the next thing you will have to do is to delete some leftovers in the registry.
Press Windows Key + R, and type Regedit.
A window should pop up. You will have to do now to copy each of the locations below, paste them into the registry search bar, and then look for any folders related to Call of Duty Warzone/launcher and delete them.
- + more locations on the files.
At each location, you will see a lot of folders on the left side.
Right-click on any folder related to Call of Duty Warzone and the Launcher and choose Delete.
That’s it, by clearing all those files, you just made sure there is no way those files can link you back to the 350ms ping ban while searching for a match.
Step 2 – Change your Disk’s Serial Number
VolumeID by Microsoft is used to change the disk’s serial number/ID.
Hard drives are one of the most common hardware parts that get blacklisted on a Call of Duty Warzone 350ms ping ban. Luckily, changing your hard drives’ serial number is effortless to bypass, and it won’t cause any issues on your hard drives or files if you follow the steps below.
Below you can find how to change the serial numbers of all of your hard drives.
Navigate to the folder with the files you previously downloaded and go to step 2. You should see a file named “Change Disk IDs“. Right-click on it, and choose “Run as administrator“.
It will open a command prompt with all your drives, and it will ask you which drive ID you would like to change. Type just the letter of the Drive and hit enter.
Press any key to continue, and your drives SN should be changed(you will see the confirmation message).
Do the same thing for the other drives once you get a message that the drive ID has been changed successfully. Once you’ve changed all of your drive ids, move on to the next step of the guide.
If you want to change the Drive ID manually or revert the changes, follow the steps below:
Run the “Change Disk IDs.cmd” file as administrator and close it directly. We are doing this only to move the required files on the C drive.
Run CMD as administrator and type the following commands:
- cd c:/
- Now for every disk that you have, type -> vol (Disk letter): for example, if you have two disks, let’s say, C & D. You will have to type the following commands:
- vol c:
- vol d:
- Copy the Volume Serial Number of your disks in a separate text file and save it.
- volumeid c: (type the Volume Serial Number you saved before, and change the last two digits to whatever you want) Example: If the previous Volume Serial Number was AB98-1233 , type the command -> volumeid c: AB98-1211
- Do the same for the rest of the disks(if you have any)
- You should get a message the volume id is updated.
Okay, that’s it, you’ve successfully changed the hard drives’ serial numbers IDs, and you are one step closer to fixing the 350ms ping ban from Call of Duty Warzone.
Step 3 – Change HWIDs of everything.
AMIWIN64 is used in this step.
Now it’s time to change the system UUID, Baseboard serial number, System Serial, Chassis serial, etc. This is where all the magic happens. We are going to change every single hardware identifier that Call of Duty Warzone flags on a 350ms ping ban.
Navigate to “STEP 3 – Change HWIDS” folder, right-click on the “Change ALL HWIDs.cmd” file and choose “Run as administrator“.
Then you will be asked to press any key to continue changing your HWIDs and the command prompt will show you upfront your new HWIDs for every hardware part.
Once you press any button to continue, your Command Prompt should look something like the one below.
You’ve successfully changed all your systems HWIDs, and you are ready to move on to the next step.
Step 4 – Edit HWID Registry keys
Next, you will need to edit a few registry keys that could link you back to the Call of Duty Warzone 350ms ping ban. Below you can find step-by-step instructions on how to edit all registry keys that could possibly link you back to the 350ms ping COD Warzone ban.
Press Win Key + R on your keyboard, and a small window on the bottom left should appear. Type “Regedit” and hit enter.
Now copy this path -> HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography and paste it into the search bar on the top side.
Go to the GUID Generator website, click on the button to generate a new GUID, and copy it.
On the right side of the registry window, you should see the “MachineGuid” key. Double click on it, replace the GUID with the generated one, and click OK.
Again, copy this path -> Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\IDConfigDB\Hardware Profiles\0001 and paste it into the search bar on the top side.
Go to the GUID Generator website, click on the button to generate a new GUID, and copy it.
On the right side of the registry window, you should see the “HwProfileGuid” key. Double click on it, replace the id with the generated one, and click OK.
Now let’s move on to the next step!
Step 5 – Mask & Setup your IP Address
Your IP address is the most crucial security step that will even make or break everything you did above to fix the Call of Duty Warzone 350ms ping ban while searching for a match. The best way to change your IP address is to use a VPN service or a proxy server(Proxys need an excellent setup to avoid disconnections and unhiding your IP, so let’s stick with the VPN).
This is the most commonly asked question. Do I need a VPN? YES! You do. If you don’t use a new IP, your new Call of Duty Warzone account will get linked to the 350ms ping ban, and it will be shadowbanned again, sometimes instantly or after a few hours/days.
Do I need to play the game with a VPN connection at all times? Yes, that’s one of the reasons I recommend getting NordVPN because you will have the lowest ping possible on Call of Duty Warzone.
Why not use a Free VPN? Slow speed, high ping, and disconnections all the time which can leak your IP and get you banned instantly again. Don’t believe me? Go ahead and try yourself.
I can’t find a completely free method because you will need a VPN 100% to play Call of Duty Warzone again, but you can get NordVPN for 3.29$ per month, which is the best possible solution I can think of.
How to correctly set up the VPN to protect you from getting your actual IP address seen by Call of Duty Warzone:
Step 6 – Change your MAC address.
The next thing that immediately gets banned by Call of Duty Warzone after the IP address on any ban as well as the 350ms ping ban, is the MAC address, so you have to make sure you have a different one. Below you can find step-by-step instructions on how to change your MAC address on any Windows machine.
Navigate to Settings.
Click on Network & Internet.
Click on “Change adapter options“.
Right-click on your primary internet adapter and click on “Properties“.
Choose Client for Microsoft Networks, and click Configure.
Navigate to the Advanced tab and choose Network Address.
Now go to this website, generate a new mac address, copy it, and paste it to the Network address box.
Click OK, and you will be disconnected for a few seconds/minutes from the internet. No worries, it will get back up.
Now do the same thing for the NordVPN adapter. Right-Click on the NordVPN adapter and choose Properties.
Choose “Client for Microsoft Networks” and click “Configure“. Navigate to the Advanced tab, choose MAC Address, and paste a newly generated MAC address from the generator.
Once you’ve changed your ethernet/wifi adapter and the NordVPN’s adapter, MAC Address, proceed to the next step.
If the above method didn’t work for you or some options were missing
Download Technitium MAC Address Changer and follow the instructions below.
There is a program to change your MAC address in the previously downloaded files. Select your Network Connections, click on the “Random MAC Address” button, and click “Change Now!“.
Step 7 – Create or buy a new game account.
Navigate to the Call of Duty Warzone Official Website and create a new account with new details.
- Use the most commonly used email providers ( Gmail, Hotmail, Yahoo, Protonmail, etc.) Avoid temporary emails.
- The same goes for the phone number. Don’t use the free numbers you’ll find on websites on the internet. Instead, use a phone number you never used before, get a cheap number for 3.49$/Month from Tossable Digits.
- Don’t use Russian Numbers until further notice.
Step 8 – Create a new Windows User.
Recently I updated this guide to avoid reinstalling Windows from scratch, but instead of that, you will have to create a new Windows user. Pretty easy to do so; follow the steps shown in the video below.
Step 9 – Change Monitor HWID
In some rare cases, your monitor serial might get banned as well. I would say that it’s worth changing it since the process is straightforward and quick. To change your Monitors ID Serial, follow the steps below:
Navigate to the folder -> STEP 9 – Change Monitor HWID, right-click on CRU.exe, and choose “Run as Administrator“.
On the top side of the Custom Resolution Utility app, choose your Monitor/s and click on the “Edit” button.
Change the value of the ID Serial and click OK.
Step 10 – Hide Mouse, Keyboard, and Controller serial numbers.
Getting your mouse, keyboard, controller, and other peripherals banned or flagged is rare, and it mostly happens in manual HWID bans. Since it will only take you one to two minutes to hide all your peripheral serial numbers, I recommend doing it to be safe.
I never needed to hide any of my peripherals ID to bypass the 350ms ping ban on all the tests I’ve done on different games. Still, many people have been sending me messages to include it as part of the solution since it helped many of them.
Below you can find step-by-step instructions on how to hide your mouse, keyboard, controller, and any computer peripheral serial number:
Navigate to the “STEP 10 – Change Mouse, Keyboard, Controller, SNs” folder or download USBDeview, right-click on USBDeview.exe , and choose “Run as administrator“.
Locate your Mouse, right-click on it, and select “Open In RegEdit“.
Right-click on the marked folder on Registry Editor and choose “Permissions“. A window will pop up, and you should find the “Read” column and tick the “Deny” option. Once you do that, click Apply and OK.
Repeat the same steps for your keyboard and controller(if you have one).
Step 11 – Download and Install the game.
Now it’s time to go ahead and download Call of Duty Warzone and install it on your computer.
Please navigate to the official website of Call of Duty Warzone, download it, install it, and log in with your new account.
