What is OnStar Wi-Fi?

OnStar Wi-Fi is a built-in Wi-Fi hotspot service available in specific luxury cars from General Motors. This in-car internet service converts your vehicle into a mobile Wi-Fi hub, allowing you and your passengers to access the internet while on the go.

Whether you are commuting to work, school, or vacation, this in-vehicle Wi-Fi keeps you connected. It lets you stay in touch with family, friends, or business associates wherever your travels take you. You can check your emails, make video calls, chat online, stream movies, or play games in your car.

OnStar Wi-Fi is fast and reliable, guaranteeing uninterrupted internet access. Besides, it has a 50 feet range outside the car, making it suitable for camping or tailgating. 

Introducing OnStar Wi-Fi

The best part is that you can connect up to seven devices simultaneously without experiencing reduced bandwidth or connectivity issues.

How Does OnStar Wi-Fi Work?

OnStar Wi-Fi is not different from any other Wi-Fi hotspot. The only noticeable distinction is that it is available in your vehicle rather than on your premises. 

Cars equipped with OnStar Wi-Fi have a built-in wireless router to facilitate multiple connections of up to seven devices. The service receives 4G LTE internet signals provided by AT&T, ensuring seamless internet access in the carrier’s coverage areas. 

However, the OnStar Wi-Fi service is not free – you require a paid data plan to connect to the Wi-Fi hotspot. To purchase a plan, you must download and install a smartphone app associated with your vehicle (myChevrolet, myCadillac, myGMC, or myBuick).

Thereafter, create an online account by filling out your details. You can purchase a data plan or request your free trial if you meet the eligibility requirements.

The app allows you to pick an SSID (network name) and create a password for your OnStar Wi-Fi hotspot. Alternatively, you can configure your hotspot via the vehicle’s touchscreen menu. Select Wi-Fi Settings to change your SSID and password.

Once you have set up your network name and password, you only need to search for your Wi-Fi hotspot name on your device and enter your password when prompted to connect to OnStar Wi-Fi.

Note: Your vehicle must be ON or in Accessory Mode to connect to OnStar Wi-Fi

How to Connect to OnStar Wi-Fi

Troubleshoot & Fix OnStar Wi-Fi Not Working

As you can see, connecting to OnStar Wi-Fi is a breeze. This in-car Wi-Fi hotspot does not have complex requirements or procedures. 

However, OnStar Wi-Fi is not exempt from connectivity issues. Sometimes, it might stop working unexpectedly, leaving you upset as you try to fix the problem. 

Fortunately, we have proven tips to help you troubleshoot and fix “OnStar Wi-Fi not working” issues. Here’s what you can do to resolve the problem:

OnStar Wi-Fi Not Working – Try This Simple Fix

1. Turn On Your Vehicle

The first step to fixing OnStar Wi-Fi issues is to check your car status. OnStar Wi-Fi cannot work if your vehicle is OFF. The Wi-Fi hotspot draws power from your car’s battery to transmit signals to your devices and function appropriately. 

Simply turn ON your vehicle’s ignition or set it to “Accessory Mode” to fix OnStar Wi-Fi connectivity problems.

Note: Accessory Mode does not start the car engine but allows you to use various car accessories, such as the radio, windshield wipers, and the OnStar Wi-Fi hotspot.

2. Check Your Subscription

As mentioned above, OnStar Wi-Fi is a subscription service, meaning you must purchase a renewable data plan to connect to your Wi-Fi hotspot. This means you can’t access this in-vehicle internet service with an expired subscription.

Pricing is usually monthly, but you can opt for a 12-month or a 24-month prepaid data plan for extra convenience. Alternatively, you can use the OnStar app to set up renewable monthly payments using your credit card, debit card, or PayPal account.

Note: You must have a GM online account to purchase data plans and manage your subscriptions.

3. Check Your Data Balance

Sometimes, your OnStar Wi-Fi hotspot might malfunction because you have run out of data. Unless you are on the unlimited plan, you may deplete your available data allowance if you stream heavy online content. 

Streaming movies, downloading large files and games, and video conferencing can quickly usurp your data. You must purchase a new plan before the expected expiry date to continue accessing the internet in your car.

You can quickly check your data balance via the smartphone app associated with your car or by logging into your GM online account. You can also push the OnStar blue button on your vehicle’s dashboard to consult an advisor.

OnStar has various plans tailored to meet your data needs. If you are into heavy streaming and gaming, you can purchase an unlimited in-vehicle data plan from AT&T for as little as $25 per month. 

The premium plan costs more ($49.99) but has additional features such as automatic crash response, stolen vehicle assistance, and emergency services, besides the unlimited data offering.

4. Check Device Limit

Unlike other Wi-Fi hotspots that support over 200 simultaneous connections, OnStar allows up to seven connected devices at once.

This means you can connect your smartphones, laptops, cameras, and tablets to your OnStar Wi-Fi hotspot, but you can’t exceed more than seven connected devices at a time. Any other device you try to add to the network won’t connect.

Consider disconnecting some gadgets before adding others to resolve connectivity issues.

Tip: You can check the OnStar app to see your connections or physically count the number of connected devices to find out if they have exceeded the limit. 

5. Check Your Wi-Fi Range

Your OnStar Wi-Fi hotspot might stall and stop working because you are not within the network range. 

Wi-Fi networks usually have a limited range, not exceeding 150 feet indoors, and OnStar Wi-Fi is no exception. It has a lower network range of only 50 feet from the vehicle. 

So, if you are outside your car, your connection might fail, or you may experience frequent downtimes because you are not close to the router. 

To resolve this issue, move closer to the router/car and ensure you are within the network range.

6. Check OnStar Coverage Area

OnStar Wi-Fi relies on 4G LTE internet connectivity provided by cellular carriers like AT&T. Even as the world shifts towards 5G networks, the reality is that 4G LTE coverage is not available everywhere, particularly in rural areas.

Your OnStar Wi-Fi hotspot might lose its service when driving your car outside the designated coverage area. You may notice your internet connection has suddenly become slow, or you might lose your connection in areas where the network coverage is prone to fluctuations.

To fix this issue, move to designated coverage areas. You can check the coverage map on the smartphone app to identify regions with poor cellular signals.

7. Check for Obstacles & Obstructions

Your OnStar Wi-Fi hotspot is like any other wireless network. It is prone to signal interference and latency issues caused by physical obstacles and obstructions such as trees, metals, and tall buildings.

You may notice intermittent disruptions and disconnections if you are in an underground tunnel or an area with several tall buildings since network signals cannot reach your OnStar router.

The easy way out is to change your location to a more open area. Consider driving away from physical obstacles that might block network signals and try reconnecting to your in-car OnStar Wi-Fi hotspot.

8. Verify Your SSID & Password

You might have trouble connecting to OnStar Wi-Fi because you’ve selected the incorrect network name or entered the wrong Wi-Fi password

Consider verifying your SSID (network name) and password before reconnecting to the Wi-Fi hotspot. You can check your network details on the smartphone app associated with your vehicle.


If unsure, you can set up and customize your SSID and password from scratch. Press the push-to-talk button on the dashboard and select Wi-Fi Settings. Push the blue OnStar button to customize your SSID and create a new password to secure your network.

9. Restart Wi-Fi Hotspot

Another quick but effective way to fix an OnStar Wi-Fi hotspot that is not working is to restart the built-in router

As you know, your OnStar-equipped vehicle has a wireless router that allows you to access the internet in your car. Restarting this router can help resolve minor bugs and glitches causing your hotspot to malfunction.

Restarting your OnStar Wi-Fi hotspot is easy. Turn off your car’s ignition and wait for about 2-3 minutes before turning the ignition on again. Wait for the router to boot and try to connect to the hotspot.

10. Contact OnStar Wi-Fi Support

If all else fails, you may contact OnStar support via online chat or phone for additional help. The technical team might have extra tips to walk you through the problem.
