I've had this Aircard for about 9 mos now, and my company used to use the Nortel VPN client as their intranet access. I never had problems with the two.
Recently, they switched us to a Juniper Networks VPN, and now I'm getting BSOD's whenever I'm on the VPN with the Aircard. I got 4 on Friday last week alone!
The Juniper VPN works fine IF I'm using either a Hardline or 802.11 as my internet connection, so this all has my IT dept befuddled.
