Prometheus,
Technically under CE the connection type isn't an issue. So long as it conforms to TCP/IP version 4 standards you will be able to use the device on any connection at any speed.
(Ignoring bus limits for those who like to be picky
).
Try downloading the Nokia 6210 driver for CE1 from our
HCL.
As you probably know by now you need to enter specific dial information into the number, so you will need to get the dial-up profile settings from your phone's manual.
Let us know how you get on.
