Troubleshooting

•

If your Broadband Home Router is set to routing mode and you use private IP

addresses on the LAN, make sure Network Address Translation (NAT) is enabled.

•

Your PC may not recognize any DNS server address. Check your DNS setting on

the Broadband Home Router.

2. Check the physical connection between the Broadband Home Router and the

xDSL/cable modem.

At the DOS prompt, ping the IP address of the Broadband Home Router. That is, ping the

WAN IP address that you set or provided by your ISP. If the following response occurs:

Relay from WAN IP address(xxx..xxx.xxx.xxx) bytes=32 time=100ms TTL=253

Then the connection between the Broadband Home Router and the network is OK.

If you get a failed ping with the response of:

Request time out

Then the connection is fail. Check the cable between the Broadband Home Router and the

network.

3. Check the DNS setting of the Broadband Home Router.

At the DOS prompt, ping the IP address of the DNS provided by your ISP. For example, if

your DNS IP is 168.95.1.1, then ping 168.95.1.1. If the following response occurs:

Relay from 168.65.1.1 bytes=32 time=100ms TTL=253

Then the connection to the DNS is OK.

If you get a failed ping with the response of:

Request time out

Then the DNS is not reachable. Check your DNS setting on the Broadband Home Router.
