FAQs (Frequently Asked Questions)

Q1: I have problem connecting to the web-management interface.
1. Check that the power LED in the front of the DI-804HV is ON.
2. Check that the link light status of the Ethernet port used by your computer is ON.
3. Check your computer's network settings - verify that your TCP/IP settings are correct. In windows 95/98, you can type winipcfg in the DOS prompt. In windows XP/NT/2000, you can type ipconfig in DOS prompt.
4. Check to see that your computer's IP address is in the same network as the DI-804HV. The computer's IP address should be in the range from 192.168.1.2 to 192.168.1.254.
5. Type http://192.168.1.1 in your browser's URL interface. TOP>>

Q2: The DI-804HV has successfully connected to the ISP (from the connection status shown in the Device Information screen) but I cannot surf the Internet.
1.Check if your computer's IP settings are correct.
  a.Your computer's IP address should be in the range from 192.168.1.2 to 192.168.1.254.
  b.Your computer's network mask should be 255.255.255.0.
  c.Your computer's gateway should be 192.168.1.1 (The IP address of the DI-804HV).
  d.Your computer's DNS IP settings should be a valid ISP DNS server IP address.
2. Try to ping an existing Internet IP, ex: the DNS IP address. TOP>>

Q3: The DI-804HV has problems getting IP settings from the ISP
1.Make sure that your Cable or DSL modem is connected properly.
2.Try resetting your Cable or DSL modem by powering the modem off and on.
3.If you are using Dynamic IP addressing, make sure that your Cable or DSL modem is DHCP capable.
4.Some Internet Service Providers (ISP) require a MAC address to be registered with them. In this case, make sure you specify the correct WAN Ethernet MAC address required by the ISP under "Home" > "WAN" > "Dynamic IP address".
5.If your connection is DSL and your ISP requires you to input username and password, then your connection is a PPPoE connection. To connect to the ISP's PPPoE server, you have to input your PPPoE username/password from "Home" > "WAN" > "PPPoE".
6.If your connection is Cable and your ISP requires you to input a specific host computer name, you have to input the host computer name from "Home" > "WAN" > "Dynamic IP address". TOP>>

Q4: If all else fails, what can I do?
1.Reset your Cable modem or DSL modem by powering the unit off and on.
2.Reset the DI-804HV back to factory default settings in "Tools" -> "System Settings".
3.Reconfigure the device using the "Setup Wizard". TOP>>

Q5: Does the home internet gateway support PPP over Ethernet (PPPoE)?
Yes, the router does support PPPoE. To setup PPPoE support:
1.Enter the web-based management utility by typing "http://192.168.1.1" in your web browser's address line. Press Enter
2.After logging in go to "Home" > "WAN" > "PPPoE"
3.Enter the username and password provided by your ISP.
4.Click Apply to save the settings.
5.Go to "Device Information" to ensure that PPPoE is enabled and that the status is connected. TOP>>

Q6: How will I be notified of new firmware upgrades?
All new firmware will be posted on D-Link support website at http://support.dlink.com, where they can be downloaded for free. TOP>>

Q7: Does it matter if I use a Dynamic IP address or Static IP address for my computer?
No, the DI-804HV can be configured for either case. For Static IP address, you have to make sure of the following:
1.The IP address is in the range from 192.168.1.2 to 192.168.1.254.
2.The network mask is 255.255.255.0.
3.The gateway is 192.168.1.1.
4.The DNS server IP address is correctly setup.
For dynamic IP setting, you can check if your computer has successfully acquired IP settings from the DI-804HV. We strongly recommend that your computer is setup to acquire IP settings from the DI-804HV DHCP server. TOP>>

Q8: Does the DI-804HV support VPN?
Yes, the DI-804HV supports VPN (PPTP pass-through and IPSec pass-through). The DI-804HV supports multiple concurrent VPN sessions. TOP>>

Q9: Does the DI-804HV prevent hacker attacks?
Yes, DI-804HV supports hacker attack logging and will be able to log most recent attacked hacker patterns. You can view the logs at "Status" > "Log". TOP>>

Q10: How to setup Dynamic VPN?
VPN Gateway-A:
1. Enter the tunnel name that you want to use.
2. Enable VPN and Dynamic VPN option.
3. Enter LAN subnet and netmask into local subnet and netmask field. (EX: Local Subnet: 192.168.1.0, Local Netmask: 255.255.255.0)
4. Enter preshare key that you want to use. (Note: The preshare key must be the same on both sides of VPN tunnel.)
5. Select IKE proposal: enter the proposal name and add it to IKE proposal index list when finish setting. (Note: The IKE proposal must be the same on both sides of VPN tunnel.)
6. Select IPSec proposal: enter the proposal name and add it to IPSec proposal index list when finish setting. (Note: The IPSec proposal must be the same on both sides of VPN tunnel.)
VPN Gateway-B:
1. Enter the tunnel name that you want to use.
2. Enable VPN option.
3. Enter LAN subnet and netmask into local subnet and netmask field. (EX: Local Subnet: 192.168.2.0, Local Netmask: 255.255.255.0)
4. Enter LAN network of VPN Gateway-A into remote subnet and netmask field. (EX: Local Subnet: 192.168.1.0, Local Netmask: 255.255.255.0)
5. Enter WAN IP of VPN Gateway-A into Remote Gateway field.
6. Enter preshare key that you want to use. (Note: The preshare key must be the same on both sides of VPN tunnel.)
7. Select IKE proposal: enter the proposal name and add it to IKE proposal index list when finish setting. (Note: The IKE proposal must be the same on both sides of VPN tunnel.)
8. Select IPSec proposal: enter the proposal name and add it to IPSec proposal index list when finish setting. (Note: The IPSec proposal must be the same on both sides of VPN tunnel.)
The VPN tunnel will be built when hosts under VPN Gateway-B want to connect to hosts under VPN Gateway-A. You can use PING command to check status of VPN tunnel. If hosts under VPN Gateway-B can get PING response messages from hosts under VPN Gateway-A, it means that VPN tunnel has been built successfully.
