Internet Access
PC cannot access Internet Use the ping utility to check whether your PC can communicate with
the ADSL Router’s LAN IP address (by default 192.168.1.1). If it cannot,
check the Ethernet cabling.
If you statically assigned a private IP address to the computer, (not a
registered public address), verify the following:
• Check that the gateway IP address on the computer is your public IP
address. If it is not, correct the address or configure the PC to
receive IP information automatically.
• Verify with your ISP that the DNS server specified for the PC is valid.
Correct the address or configure the PC to receive this information
automatically.
• Verify that a NAT rule has been defined on the ADSL Router to
translate the private address to your public IP address.
PCs cannot display Web pages on
the Internet.
Verify that the DNS server specified on the PCs is correct for your ISP.
You can use the ping utility to test connectivity with your ISP’s DNS
server.
