Q1: I have problem connecting to the web-management interface.
  1. Check that the power light status of the DWL-1750 is on.
  2. Check that the link light status 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 DWL-1750. The computer's IP address should be in the range from to
  5. Type in your browser's URL interface.
Q2: The DWL-1750 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 to
    b. Your computer's network mask should be
    c. Your computer's gateway should be (The IP address of the DWL-1750).
    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.
Q3: The DWL-1750 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 Dymanic IP addressing, make sure that your Cable or DSL modem is DHCP capable.
  4. Some ISPs require a MAC address to be registered with them. In this case, make sure you change the WAN Ethernet MAC address to the MAC address they require 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".
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 DWL-1750 back to factory default settings in "Tools" -> "System Settings".
  3. Configure the device with the "Setup Wizard".

Q5: Does the home internet gateway support PPP over Ethernet (PPPoE)
Yes, the router does support PPPoE. To setup PPPoE support:

  1. Reach the web-based management utility by typing "" 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.

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.


Q7: Does it matter if I use a Dynamic IP address or Static IP address for my computer?
No, the DWL-1750 can be configured for either case. For Static IP address, you have to make sure the following:
  1. The IP address is in the range from to
  2. The network mask is
  3. The gateway is
  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 DWL-1750 (for Windows 95/98, type winipcfg in DOS prompt). We strongly recommend that your computer is setup to acquire IP settings from the DWL-1750 DHCP server.
