III. Troubleshooting
You can locate the problems as follow.
1) If the power indicator of D-20 is on, it means the power connection is normal; if it is
off, check the power connection of D-20.
2) There are five green indicators of signal strength on the panel of D-20. If none of
the signal strength indicator is on, make sure the CDMA network covers your
location area.
3) If there is CDMA network coverage, check the network mode. For the primary
users, the HYBRID network mode is recommended.
4) The”1”,”2”, “3” and “4” indicators of D-20 represent the Ethernet interfaces. If the
indicator is off, check the physical connection of the corresponding Ethernet
interface.
5) Make sure that
PPP Username
and
PPP Password
are correctly configured. For
details, see 3.3.5 I. "Configuring the parameters of WAN ".
6) If DHCP service is disabled, and the host still adopts the automatic mode, the host
cannot access the Internet. You can set the IP address of the host manually. For
details, see Figure 4-1.
