Problem with Internet Access
Problem: CapTel display screen says "Check Network Settings"
n
Check that Internet access is working: Are you able to access the
Internet via a computer in your home?
n
If you get your Internet access through your Digital Cable service,
check that your TV is still getting cable channels. If not, your cable
service may be temporarily down, affecting your Internet service.
n
Do you have to enter a password every time you access the
Internet? If so, you may need to connect a router to your DSL or
cable modem, and then connect the CapTel 880i to the router.
n
If you've plugged the CapTel 880i into a router, does your router
support DHCP? Check the specifications in the instruction
manual that came with your router. If your router only supports
static IP addresses, contact Customer Service for assistance. Your
Internet service provider may also be able to help you identify
how your Internet service is configured.
n
Check that your Internet modem (DSL modem or Digital Cable
modem) supports DHCP. While most Internet modems support
multiple protocols, some modems are set to only PPOE. CapTel
880i should be used with DHCP support. Your Internet service
provider can confirm/adjust the modem settings for you.
n
If you are installing CapTel in a business environment (or in a
"locked down" environment), your network firewall security may
be blocking communication from the network to your CapTel 880i.
Please contact CapTel Customer Service for assistance setting up
your CapTel phone to work with your network security.
