I may have an
integrated modem/
home router. How
can I find out?
If you have a single device that plugs directly into your
cable/DSL jack and that you can connect multiple
computers into (allowing each to access the Internet),
you have an integrated modem router.
I have an integrated
modem/ home router.
I don’t know which
section to use in this
guide.
While integrated modem/home routers are not explicitly
supported, you can typically get the service to work if you put
the integrated modem/router in bridge mode.
Check with your cable/DSL provider to see if it supports
putting integrated modem/routers in bridge mode, and if so,
how to put your device into bridge mode.
I have a USB DSL
modem.
DSL modems with only a USB interface are not supported.
I have a satellite
broadband Internet
connection.
Satellite broadband connections are not supported.
I have a private IP
address.
While private IP addresses are not explicitly supported, you
can typically get the device to work if you put your router into
what is known as bridge mode.
Check with your router’s owner’s manual to see if it supports
bridge mode and how to do so.
I can’t get this to
work with my
company’s VPN.
AT&T CallVantage
SM
Service supports most VPN clients.
Check the settings on your VPN Client to verify that “keepalive”
messages are disabled. Also, select “allow VPN to pass
through NAT”, if this option is available. You may have to dis-
able (uncheck) “negotiate UDP encapsulation with VPN tunnel
server”, if this option is available. You may also have to contact
your network administrator to understand what other settings
may need to be modified for your setup.
My data service is
lost every once in a
while, but I still have
a dial tone.
I am using a home
router and have to
reboot everything to
get the data to work
again.
If you are using a home router, make sure your device has the
most up-to-date software available from the manufacturer.
Software updates are readily available from the manufacturer’s
Web site. Check their site for your model, and compare the
most recent version they are offering against the version your
device is running. If they are not the same, follow the upgrade
instructions on the Web site or in your router’s manual.
