5.1.2 CHECK YOUR CONFIGURATION
We explain here the configuration of PPPOE using Windows 2000 operation system as an example. For
other operation systems the process is similar.
1、 Enter the device manager to check if Ethernet adapter is correctly installed. If any problem exists,
please re-installed it;
2、 Check the configuration of Ethernet adapter in PC. Try to manually set IP address that is in band
192.168.1.x without conflict. See 3.2;
3、 Try to run command “ping 192.168.1.1” on command line mode. If the response returns “time out”,
please check Ethernet connection and IP settings;
4、 If this modem is reachable, try to run ping with a known outer IP, e.g. the DNS server IP of ShangHai
Online: “ping 202.96.209.133”.
l If ping is reachable, there shall be no problems in the modem. Please see step 5;
l If ping is not reachable, see step 6 and check if the configuration is correct.
5、 Please try to ping a certain outer URL, e.g. “ping www.google.com”.
l If ping is reachable, there shall be no problems in the network settings. Please check the settings
of the PC terminal, e.g. whether the security level is too high, or whether anti-virus firewall is
installed;
l If ping is not reachable, check the DNS setting of Ethernet adapter. See 3.2.
Note 1：The precondition is that the LAN settings in the modem has not been modified.
Note 2：We usually start command line mode in Windows xp as follows: click on the “RUN” item of Windows
Start Menu, input characters “cmd” in the input box popped up with an “Enter”. The window
subsequently popped up is the command line window.
Note 3：The returned values of ping command in the following format show the standard of “reachable”
Figure 5.1
6、 If ping of the modem is reachable but ping of the outer fixed IP is unreachable, attention should be
concentrated upon device settings. Please enter the configuring interface following the instructions in
this manual.
（1） Check first the number of connections. If more than one connection exists, for troubleshooting ,
delete unused connections and remain the one connection you are using.
