  1. Check that the power light status of the DWL-1750 is on.

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".

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 192.168.0.2 to 192.168.0.254.
  2. The network mask is 255.255.255.0.
  3. The gateway is 192.168.0.1.
  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 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.
