You Cannot Access the Internet After
Making a Direct or Modem Connection to the 8500S:
If you are connected to the 8500S via modem or direct connect, you cannot ac-
cess any other TCP/IP connection. The PPP connection becomes the default proto-
col and the default gateway defaults to the 8500S unit's IP address. This means
that all existing network connections point to the 8500S unit. To correct this:
A) In Start > Settings > Network and Dialup Connections, open the direct or mo-
dem connection you are using to connect to 8500S.
B) Select "Properties."
C) Click the tab that reads "Networking."
D) Highlight "Internet protocol (TCP/IP)."
E) Select "Properties."
> PC C and check the interface setting.
