|
| Q1: I have problem connecting to the web-management
interface. |
- Check that the power light status of the DWL-1750
is on.
- Check that the link light status is on.
- 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.
- 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 192.168.0.2 to 192.168.0.254.
- Type http://192.168.0.50:2000/ in your browser's
URL interface.
TOP>> |
| 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. |
- Check if your computer's IP settings are correct.
a. Your computer's IP address should be in the range from 192.168.0.2
to 192.168.0.254.
b. Your computer's network mask should be 255.255.255.0.
c. Your computer's gateway should be 192.168.0.1 (The IP address of
the DWL-1750).
d. Your computer's DNS IP settings should be a valid ISP DNS server
IP address.
- Try to ping an existing Internet IP, ex: the
DNS IP address.
TOP>> |
| Q3: The DWL-1750 has problems getting IP settings
from the ISP |
- Make sure that your Cable or DSL modem is
connected properly.
- Try resetting your Cable or DSL modem by powering
the modem off and on.
- If you are using Dymanic IP addressing, make
sure that your Cable or DSL modem is DHCP capable.
- 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".
- 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".
- 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? |
- Reset your cable modem or DSL modem by powering
the unit off and on
- Reset the DWL-1750 back to factory default settings
in "Tools" -> "System Settings".
- Configure the device with 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:
|
- Reach the web-based management utility by
typing "http://192.168.0.1" in your web browser's address
line. Press Enter
- After logging in, go to "Home" ->
"WAN" -> "PPPoE"
- Enter the username and password provided by
your ISP.
- Click Apply to save the settings.
- 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.
TOP>>
|
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: |
- The IP address is in the range from 192.168.0.2
to 192.168.0.254.
- The network mask is 255.255.255.0.
- The gateway is 192.168.0.1.
- 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.

| Advanced |
Virtual Server
The DWL-1750 can be configured as a virtual server so that remote
users accessing Web or FTP services via the public IP address can be automatically
redirected to local servers in the LAN network. Depending on the requested
service (TCP/UDP port number), the DWL-1750 redirects the external service
request to the appropriate server within the LAN network.
Name - The name referencing the virtual service.
Private IP - The server computer
in the LAN network that will be providing the virtual services.
Private Port - The port number of the service used by the
Private IP computer.
Protocol Type - The protocol used for the virtual service.
Public Port - The port number on the WAN side that will be
used to access the virtual service.
Schedule - The schedule of time when the virtual service will
be enabled.
|
| |
| Filters |
|
The DWL-1750 can
be setup to allow access to wireless clients using the MAC addresses for
the wireless adapters. This is the same as an "Access Control List".
By default, the MAC filter setting is disabled.
MAC Address: You have the option to manually enter the
MAC address of the wireless client into the field. The "Clear"
button is to erase a wrong entry.
MAC Address Filter List
The list will display the MAC address of the clients currently included
in the "Filter List". You have the option of editing and deleting
an entry in the Filter List by selecting the appropriate icon to the right
of the entry.
|
| |
Firewall
Use IP Filters to deny LAN IP addresses from accessing the
Internet. You can deny specific port numbers or all ports for the specific
IP address.
IP - The IP address of the
LAN computer that will be denied access to the Internet.
Port - The single port or port range that will be denied access
to the Internet.
Schedule - This is the schedule of time when the IP Filter
will be enabled.
Firewall Rules is an advance feature used to deny or allow
or counting traffic from passing through the DWL-1750. You can create more detailed rules for
the Router.

Performance
Beacon interval
Beacons are packets sent by an Access Point to synchronize a wireless
network. Specify a Beacon interval value between 1 and 1000. The default
value is set to 100 milliseconds.
RTS threshold
This value should remain at its default setting of 2432. If you encounter
inconsistent data flow, only minor modifications to the value range between
256 and 2432 are recommended. The default value for RTS Threshold is set
to 2432.
Fragmentation threshold
This value should remain at its default setting of 2346. If you experience
a high packet error rate, you may slightly increase your "Fragmentation"
value within the value range of 256 to 2346. Setting the Fragmentation
value too low may result in poor performance.

| Routing |
|
Manual specify the static route entry to determining optimal routing paths and transporting
packets through an internetwork. Each static route contains three components:
Network Address:
The Network Address and Subnet Mask can determined that the destination network.
Subnet Mask:
The Network Address and Subnet Mask can determined that the destination network.
Gateway Address:
The next hop IP address .
