Learn why your VPN may not be working

Having trouble with your VPN Service on AT&T Internet? Learn what you need to do to get connected. 

Did you just start working from home?

In some instances, your Company VPN has not been set up or needs permissions. Contacting your IT Department is recommended. They can help you:

• Authenticate your access
• Change settings on your PC

If you purchased your VPN, make sure you followed the instructions to set it up. In some instances, settings on your computer or modem have to be changed. You will need to reach out to the customer service group for your VPN.

High Ping & VPN

Keep in mind that when you use a VPN, your connection is going through additional firewall layers.  This will slow down your overall speed and increase ping times.  As an example, you may have 100 megs for your download speed without VPN, but on VPN you could be at 5 megs per second.

Also, with more people working from home, you may notice high ping when your VPN is active. This is related, in some instances, to the VPN infrastructure as it may not be able to handle the extra bandwidth. Our Internet High Ping page has more information.

You may see issues like:

• Slow download on other devices
• Streaming issues
• Trouble with Video Conferencing

Things to know

• Certain VPNs are stricter and may drop you if something seems out of the ordinary. Wi-Fi interference may scramble the packets causing this issue.
• Using a hardwired connection helps improv VPN communication
• VPNs can affect overall internet speeds
• Disconnect a VPN when it is not needed
