Little background.  I was connecting to the company AS400 over the internet
via a VPN connection.  I had a DSL connection with DSL modem attached to PC.
Not sure if it matters, but I running Windows ME and connecting with Client
Access Express 5.0.  Connection to AS400 worked fine.

Recently I set up a network at home.  PC now is connected to hub via
Ethernet connection.  I have a new DSL modem attached to the hub.  I connect
to the internet just as before with no problems.  I can connect to my AS400
using VPN connection.  My problem is that after about 7-10 minutes my
session goes down on the AS400.  The job stays active, but screen turns all
black.  It seems that the more activities I perform on the AS400, the faster
I lose my connection.  Its seems that there is some buffer of some sort that
once it gets filled, I lose the session, but that is just a guess.

The network guys at work set the network up and made some changes to Network
settings on my pc.  They do not know why am I losing my connection.   Other
programmers are connecting through same hub, only difference is that they
are using cable modems instead of DSL.

Are there any additional settings I need to check on my PC, my VPN
connection, or hub?  Any advice would be appreciated.

Thanks in advance,

Lester
