Troubleshooting Suggestion

 

 

Firstly, check to see if ADSL Link LED is solid on; if it is not, check

 

 

to see if the ADSL line is connected correctly.

 

 

If the method for acquiring the IP and DNS of the host is set to

 

 

Auto (Auto is recommended strongly), check to see if the IP

 

 

address has already been obtained correctly, and if you can ping

 

 

the IP address of the device’s LAN interface (192.168.1.1 by

 

 

default; refer to 8.2.1 ping to use the ping utility to check it out). If

 

 

you cannot ping the interface, check to see if the Ethernet cable is

 

 

OK.

 

 

My PC cannot

If the current computer is specified with a private IP address,

make sure that it resides in the same segment as that of the

 

 

device’s LAN interface, the gateway is specified as the IP address

 

 

of the device’s LAN interface, and the DNS is specified as the IP

 

 

address of the device’s LAN interface or the DNS Server the ISP

 

 

allocates. Similarly, the host should be able to ping the IP address

 

 

of the device’s LAN interface.

 

 

If the host can communicate with the device normally but cannot

 

 

connect to the Internet, login to the web page of the device (refer

 

 

to Figure 4-39Status page) at first, and check to see if the WAN

 

 

interface of the device has acquired the Internet IP address.

 

 

 

 

 

Verify that the DNS server IP address specified on the PCs is

 

 

correct for your ISP, as discussed in the above item. If you specify

 

 

that the DNS server be assigned dynamically from a server, then

 

 

verify with your ISP that the address configured on the ADSL

 

 

router is correct, and then you can use the ping utility to test

and manually modify the configuration for DNS Relay (refer to 4.3
