Another culprit is temporary glitches.

You can easily fix a Mercedes-Benz WiFi not working problem by restarting your in-car infotainment system. Simply press and hold the power button on the infotainment system for 5 seconds, and it will reboot. If this doesn’t work, reset your MBUX to factory settings. 

First, let us discuss the possible reasons your Mercedes-Benz WiFi is not working to clear the issue.

If we figure out the cause, we can take the appropriate action so your car can go back to keeping you entertained.

Why Mercedes WiFi Not Working

A car WiFi system can make things more convenient. But, when it stops working, it can be really annoying.

When this happens, it is usually of bugs and glitches on your phone and the car’s infotainment system. Make sure that you check your connection settings so you can perform the proper fixes.

If your in-car WiFi stops working, it’s because the problem is due to one of the following:

1. Minor Connectivity Issues

Your network connection may be weak. If other apps on your smartphone don’t work, your Internet may not be fast enough.

2. Incompatible Network Settings

Mercedes-Benz can become a 3G WiFi hotspot that allows you to connect up to four devices. But, this feature is only available to select models.

3. Outdated Infotainment Software

An out-of-date infotainment software can become laggy and keep your in-car WiFi from working properly.

4. Temporary Glitches

Temporary bugs and glitches can also stop the WiFi from working. They can affect the vehicles’ MBUX infotainment systems.

These are the common causes of Mercedes WiFi not working. Now that we know them, we can move on to the troubleshooting steps.

How to Fix Mercedes-Benz WiFi Not Working

Start with the easiest yet most effective method before you fix your Mercedes-Benz WiFi problem with advanced solutions.

We recommend you restart the device connecting to your vehicle’s WiFi. Whether it’s a phone or tablet, switch it off, turn it back on and reconnect with your car.

Once your smartphone has restarted, toggle the WiFi off and on again. Doing so should fix temporary bugs and glitches that interfere with the connection.  

If the problem persists, proceed with the following:

Solution #1: Forget Your Mercedes’ In-Car WiFi and Reconnect

Forgetting the in-car WiFi in your phone and connecting again refreshes your network connection.

It fixes temporary bugs and glitches that keep your WiFi from working.

This is something you’re going to perform on your phone or tablet as this resets the network connections and settings between it and the car.

Here’s how to do it:

1. Open Settings.
2. Select WiFi.
3. Tap and hold the Mercedes In-car WiFi.
4. Select Forget Network.
5. Reconnect by entering your username and password.

Note: If forgetting the Mercedes-Benz’s WiFi does not work, proceed to the next solution.

Solution #2: Restart Your In-Car Infotainment System

Restarting your in-car infotainment system can solve many problems, including the WiFi not working.

Your Mercedes is not just any other car since you can control the infotainment system separately.

You don’t even have to restart the vehicle. All you need to do is press a couple of buttons and wait for the system to reboot.

Then, follow these steps:

1. Hold the Favorite and Telephone button down.
2. Wait for 10 seconds each.
3. You will see the Mercedes-Benz logo on your screen.
4. Wait for it to reset.

Note: Start with this step if you run some issue with your MBUX.  

Solution #3: Activate Your In-Car Hotspot

If the above solutions don’t work, check if you’ve activated your in-car hotspot.

First, deactivate your in-car hotspot, then turn off your car. Activate it again and see if it fixes the issue.

Doing this resets your car’s computer and shuts down all of its systems allowing it to restart fresh minus the bugs and glitches.

Here’s how to connect your vehicle’s WiFi hotspot:

1. Go to Menu and select System > Connectivity.
2. Tap Set up a hotspot, then choose Activate vehicle hotspot.
3. Once activated, tap Connect device to vehicle hotspot.
4. The connection information should be displayed on the screen.

Note: Once connected, you will be re-connected automatically every time you get in your car.

Solution #4: Update Your MBUX Infotainment System Software

If the cause of the problem is outdated infotainment software, there is only one way to resolve it. Update your MBUX software to fix bugs and get security patches.

Some Mercedes models offer over-the-air software updates, so you don’t have to worry about driving to your nearest service center.

Here’s how to update your MBUX infotainment system software:

1. Click the Home button to get to the main screen.
2. Scroll all the way to the right to see Settings.
3. Tap Settings and click System.
4. Scroll down until you see Software Update.
5. If there are updates available, download and install them.

Tip: Check for updates regularly to keep your MBUX infotainment system from crashing.

Solution #5: Reset Your MBUX to Factory Settings

If updating your infotainment system software does not work, reset your MBUX to factory settings. Keep in mind that you will need to reconfigure your settings after this.

Just like any other device, you can reset your infotainment system. It won’t affect your car’s performance, but it can get rid of any software issues you may be experiencing.

Here’s how to restore your MBUX to default settings:

1. Using the touchpad, go to Settings.
2. Select System and scroll all the way down.
3. Select Reset.

Solution #6: Reset Your Phone’s Network Settings

If you’ve done everything to your vehicle side but you still cannot connect to your in-car hotspot, the issue may lie with your phone’s network settings.

In this case, reset your phone’s network settings and see if it clears the problem.

How to reset your phone’s network settings:

2. Tap Advanced, then Reset Options.
