Why is MW3 lagging on my PS5?

There could be several reasons why MW3 (Call of Duty: Modern Warfare 3) is lagging on your PS5. Some common causes of lag include:

1. Poor internet connection: If your internet connection is slow or unstable, it can cause lag in online games like MW3. Make sure you have a stable and fast internet connection.
2. Distance from the router: If your PS5 is too far from your router, it can cause a weak Wi-Fi signal and slow down your internet connection
3. Corrupted game files: If there are corrupted game files, it can cause MW3 to lag
4. Network congestion: If there are too many devices connected to your network, it can cause network congestion and slow down your internet connection
5. Server issues: If the game’s servers are experiencing issues, it can cause lag in MW3

Solution 1: Power Cycle Your Router

The first thing you can do to overcome COD MW3 lag spikes on your PS5 is to power cycle your router which could help you establish a better internet connection and potentially solve the problem.

Here’s how to do it:

1. Completely turn off your router by disconnecting the power cable from the power switch.
2. Leave it turned off for 5 to 10 minutes before plugging it back in.

It’s important to note that you should restart all devices affected by the power cycling process to ensure an accurate fix

Solution 2: Restart PS5

Whenever you encounter lagging on COD MW3 or on any other game, you should try restarting your PS5. Restarting the console will eliminate any temporary errors/glitches occurring due to the old/corrupted cache. So, here is how you can restart your PS5:

1. Press the PlayStation (PS) button on your controller.
   
2. From the menu shown, Select the Power option (right-most)
3. From the small menu that will appear on the power icon, select the last option “Restart PS5”

Solution 3: Set the Wi-Fi frequency band to 5GHz on PS5

5. Choose Wi-Fi Frequency Bands and set it to 5 GHz.
   

If you are unable to see the 5GHz option, then your Wi-Fi router doesn’t have 5GHz support, or try to connect with the 5GHz option your router generates if it has one.

Here are a few routers that we have used ourselves and you can check them out too. Here’s also a helpful video for changing your WiFi band on PS5.

Still facing the error then proceed to update your router firmware.

Solution 5: Connect to a Hotspot/Different Wi-Fi on PS5

Most of the Call of Duty MW3 network errors are due to your connected network. Either it’s too slow or their some connection issues with your network. To see if your network is not faulty, try switching to a different Wi-Fi or your mobile’s hotspot.

   In case you don’t find your Wi-Fi network, press the triangle button on your controller to scan networks.
   
5. Scroll down to your desired Wi-Fi, click on it and enter your password to connect, and see if you are facing any errors.

At the rear of your PS5 where you have put your power cable and HDMI cable, you’d find an Ethernet port where you need to insert an ethernet cable from your router.
