Hi Chris, allow us to help you with this issue.
After a quick online search I see this error usually relates to firewall, router, or VPN software issue; while these causes appear to be discarded based on the fact you get to connect with a different adapter I would like to ask: Does this happen when you connect at 2.4 or 5 GHz band?
I'm sure the issue isn't caused by any of of the above, because I am able to set up the VPN connection on the same notebook using my wireless usb network adapter. I have two accespoints, on both I get error 619 if I try to setup my VPN connection using the Intel® Centrino® Advanced-N 6235 network adapter. Here is the information you've requested:
Acces point 1
Type: ZyXel NBG-417N
Firmware version: 1.00(BFM.9)C0 (No update available)
Acces point 2
Type: ICIDU NI-707538 (Actually it is an relabeled Edimax acces point, however I can't remember the exact type number.)
Firmware version: unknown (You can't see the firmware version on the webpage of this acces point) (No update available)
Both acces points use WPA2-AES authentication using a passphrase.
Just the standard VPN connection program built-in in Windows 8.1.
