14.2Internet Access

Indication/Symptom		Troubleshooting Suggestion

My PC cannot access the Internet.

Use the PING utility described below to check whether your PC can communicate with the HM210dp/di’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, verify the following:

(Use the WINIPCFG (Windows 98/ME) or IPCONFIG (Windows 2000/XP) utility described below to check your computer(s) have compatible IP addresses)

Verify that the DNS server IP address specified on the PCs is correct for your ISP. If you specified that the DNS server be assigned dynamically from a server, then verify with your ISP that the address configured on the HM210dp/di is correct. Then, you can use the PING utility to test connectivity with your ISP’s DNS server.

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 Network Address Translation rule has been defined on the HM210dp/di to translate the private address to your public IP address. The assigned IP address must be within the range specified in the NAT rules.

Or, configure the PC to accept an address assigned by another device.

The default configuration includes a NAT rule for all dynamically assigned addresses within a predefined pool.

If you connect using a Username and Password, make sure you have entered them exactly as provided, i.e. distinguish between uppercase and lowercase letters.
