Hi Guys,

The problem with the D-link 500 we have in the office was fixed by
following the steps below. (basically a full reset and replacment iof
the firmware)

1.      Connect to the modem via serial in hyper terminal (Bits per
second = 9600)

Your prompt will look like the one below with ip numbers instead of the
"x".
x.x.x.x>


2.      Enter the commands below as shown below (please enter everything
that is after the prompt >):

x.x.x.x>ip device flush
x.x.x.x>ip subnet flush
x.x.x.x>ip route flush
x.x.x.x>ip ipatm pvc flush
x.x.x.x>ip nat delete ppp_device
x.x.x.x>ppp 1 disable
x.x.x.x>r1483 pvc none
x.x.x.x>config save
x.x.x.x>restart

3.      After those commands , the system will reboot.  Then, you will
see the following and continue with the commands as shown below:

??:??:??:??:??:??>ip device add ethernet ether //edd 192.168.0.1
??:??:??:??:??:??>ip device add ppp_device ether //ppp/DEVICE=1 20.0.0.1
??:??:??:??:??:??>config save
??:??:??:??:??:??>restart

4.      After reboot completes, run the firmware software and upgrade
the modem regardless of version..

5.      After that I simply configured the modem with username and
password. (as easy as it _should_ be)
