Why Does My McAfee VPN Keep Turning Off?

If you’re reading this, I assume you’re either a) a concerned user whose McAfee VPN kept unexpectedly turning off or b) the administrator of a large network with multiple McAfee VPN users who’re wondering why their devices keep turning off the service during peak hours. Neither one of us wants to get in trouble with our network administrator because we’re unable to log in to our VPN during our company hours. So let’s work through this together and figure out how we can get our McAfee VPN service back on so we can finish out our day. 

What Is A VPN And Why Should You Care?

If you aren’t familiar, a VPN (virtual private network) is a type of security software that allows you to connect to a private network, called a VPN server, through a public network, such as the internet.

This allows you to be securely and privately connected to resources and services on the internet, even when you’re using unsecure public networks like Wi-Fi hotspots or visiting public websites. Your security and privacy are protected because all your data is encrypted and then tunneled (encoded) prior to being transmitted to the server. If someone intercepts your data as it leaves the server, it would be unreadable to them because it would be encrypted. They would only see meaningless bits and bytes.

There are many different types of VPNs available with various security and privacy features. Some are freeware, some are paid-for. Some provide maximum security, some provide more limited functionality. You should choose a VPN that provides the functionality and features that your company needs while maintaining your required level of security.

How Do I Turn On My VPN Without Being Logged Out?

If you use the McAfee VPN on a day-to-day basis, you’ll eventually notice that after a while, the connection randomly stops working. This can be frustrating, so here’s where we’ll start: whenever this happens to you, close all your software and apps that you have open (including your web browser), including your anti-virus program. Then, turn off your computer and unplug it from the internet (if you’re plugged in during your computer’s on-time). Leave it unplugged and untouched for about 10 minutes to let the various components of your computer and the VPN have a chance to restart.

After you’ve done this a few times, you should be able to turn on your VPN without any issues, and you will no longer be randomly disconnected whenever your computer starts updating or downloading. If this doesn’t work, you can try removing the network cable from your computer’s local area network (LAN) connector, waiting 60 seconds, and then putting it back in. This will often fix “LAN connectivity” issues, which can arise when your computer misinterprets certain bytes as being LAN configuration data, and thus willful disconnects your from the internet whenever it encounters this data. You can also try resetting your network adapter by removing the ethernet cable from your computer and waiting 10 minutes. Then, plug it back in and try turning on your VPN again. 

Why Isn’t My IP Changing Whenever I Change Networks?

Whenever you switch networks (from a public network to a private network or vice versa), the service will attempt to update its record of your publicly visible IP addresses with the private IP addresses of the new network. This is called “auto-magically” changing your IP address and can be a little disorienting if you’re not expecting it. To stop this from happening, you can either choose to not change networks if you aren’t sure you’ll be reconnecting to a VPN server at the other end, or you can tell the vpn server to hold off on this change for a while.

What Happens If I Get Hacked While Using A VPN?

A hacker who breaks into your computer while you’re logged in to a VPN server will have full access to all your files and devices, as well as the ability to tamper with your network traffic in real-time. This is called “Man-in-the-Middle” (MITM) attack, and it’s always a potential threat whenever you’re connected to the internet through a public network.

If you use a VPN and you get hacked, the worst case scenario is that you’ll need to change all your account passwords and email addresses. If this happens, you’ll also need to contact the vpn company to report the issue. They’ll need to contact your bank or credit card companies to escalate the issue. While this issue is unlikely to ever happen, it’s good practice to change your passwords whenever you change networks, especially if you’re connecting to a public Wi-Fi network. Never use the same password for multiple sites, and always use a different password for each site that you use. Changing your passwords often can help prevent password reuse, reduce the risk of getting hacked, and can also help prevent other issues.

What Is A DMZ And Why Is It Useful In A VPN Environment?

A DMZ (demilitarized zone) is a type of network configuration that separates a private network (typically a LAN) from a public network (typically the internet). This is done for a number of reasons, but mainly to prevent attacks from the public network that could possibly destabilize or damage the private network. For example, a hacker could gain access to your private network and start issuing orders to your devices, or they could steal sensitive company information, such as passwords or credit card numbers.

One of the advantages of a DMZ is that it provides some level of protection to a VPN server if it is ever hacked. When a VPN server is in a DMZ, it can’t be accessed directly from the public network, which makes it somewhat less vulnerable to attacks from there. If a hacker was to gain access to a VPN server and issue some sort of command, it would first have to go through a DMZ.
