I have a Dell E4300 laptop with a Dell 5720 broadband card. I use it to connect to my company's vpn while I'm at a client's office. I make the connection first thing in the morning and after 6hours of use. The connection drops until I reboot. I reboot and I'm able to get connected for another 15-20mins. Next day everything is good for another 6 hours.
Does Verizon throttle your network activity after 6 hours?
