VPN dropped via wireless conn

Hello, I connect to work on a VPN. I use my laptop to do this. I have the
Linksys Wireless-G. I used to connect without problems on my previous laptop,
however, I no longer have that laptop as I had gotten a new one. Now,
everytime I get into the VPN, I wind up getting booted from the connection
every couple of minutes or so.

I've followed all steps to set up except for one.. there's a step I'm
supposed to take with "SafeNet Virtual Adapter" under dial-up conn. in
Network Connections. However, I don't have that option there as I'd never set
up a dial up connection from this computer. But I also didn't have one on my
previous laptop. I'm lost, any help would be greatly appreciated.
