Re: How do I connect my cable/DSL line to this device?

The 3Com® OfficeConnect® Cable/DSL Gateway does not have an internal cable or DSL modem. The gateway router is designed to connect to the Ethernet output from your cable or DSL modem. An Ethernet cable is supplied with the product for this purpose.

How to install wireless router on windows 7

D-Link routers use the connection from your Internet service provider to create a wireless network for the various Wi-Fi-enabled devices in your home or office.

Once the router is installed, you can truly enjoy the portable capabilities of your laptop or other wireless device.

D-Link routers have a straightforward installation process, despite the advanced technology behind wireless equipment.

So there is no reason to wait around for a technician to help you install your wireless equipment.

Remove the cable that is attached to the "Internet" port on the rear of your DSL or cable modem.

Plug the Ethernet cable into the "Internet" port on the modem and plug the other end of the cable into the "Internet" port on the rear of the D-Link router.

Attach the power adapter to the port on the rear of the router and plug the adapter's cord into a outlet.

Remove the power cord from your modem and wait 10 seconds before plugging it back in. This will reinitialize your modem and force it to establish a connection to the D-Link router.

Your router will immediately begin distributing a wireless network with the "D-Link" network name.

Connect your computer to one of Ethernet ports on the rear of the router and open a Web browser.

Type "" into the address bar and press "Enter." Enter "admin" into the username field and type "admin" again into the password field.

Click "OK" to open the wireless configuration page.

Click "Wireless Security Setup Wizard" to create a wireless password for your router's network. Click "Apply" to save the changes to the router's settings.

hope this helps

Linksys router problem

This sounds like a route problem. This can happen if the settings to the WAN are correct. If you are using a dialup DSL router check to make sure that it is connecting to your ISP. Same for a cable modem. Once you have verified that it is connected properly then set your WLAN gateway to point to the WAN IP number. if you are using DHCP for IP addressing for your wireless devices make sure that the gateway address is set correct also. Check DNS settings sometimes the ISP's DNS servers are not setup correctly or are not stable try using googles free DNS numbers of or

Is there anyway to keep other peoples wireless internet connections from showing up on my computer

Unfortunately no, the wireless signals that your computer is picking up are openly being broadcast with their SSIDs available to be seen. It is a radio signal, just like on the radio in your car, you will not be able to block radio stations. The best suggestion is to just connect to your wireless connection and don't worry about the others as they are not hurting anything.

My router is hooked up correctly on my desktop and my laptop shows it is connected with a strong signal, but I still cannot get online, any suggestions

If you can't get online on either machine, plug your ethernet cable directly from your cable or dsl modem into your desktop. If it shows a network connection and you still can't get online, it may be a service provider problem. I am assuming that your service provider did not ship you a router, only a modem. Hooking up 2 routers on the same connection can be very tricky.

I can get a computer on the LAN but not the WAN. All the other computers work fine but I just got a new one and am having this problem.

The WAN (Wide Area Network) port is used for access to the internet through the use of a DSL or Cable modem.

You can't connect a pc to the WAN port it must be connected to one of the LAN ports.
