Most cable Internet Service Providers (ISP) use a Media Access Control (MAC) Authentication to establish Internet connections for end-users. A MAC address is a unique 48-bit (6-byte) integer that is attached to an Ethernet NIC for each computer. To set-up your Linksys router to a Cable ISP, you have to do MAC Cloning. MAC Cloning is a procedure which enables a router to copy the MAC address of the PC that's registered with the ISP.
To setup a Linksys router with Cable connection you need to perform five steps:

  1. Verifying Internet Connection
  2. Connecting the Devices Together
  3. Checking the Router's LEDs
  4. Configuring a Linksys Router for a Cable Connection
  5. Power Cycling
NOTE: Before proceeding, use the computer that can go online when connected to the modem and follow the steps below.
Verifying Internet Connection
Connect the Broadband modem to the computer using an Ethernet cable without the router installed and make sure that the Internet connection is active. If it is not, contact your ISP. If it can go online, the PC connected to the modem is the one that's registered with the ISP.

Once an active Internet connection is established through the modem, connect the modem and the computer to the router by following the instructions below.
Connecting the Devices Together
After ensuring that you have an active Internet connection, connect the modem to the router's Internet port and the computer to any of the four Ethernet ports. For instructions, click here.
After connecting the devices, check the LEDs by following the instructions below.
Checking the Router's LEDs
The Linksys router's front panel will indicate the status of the connection. After connecting the broadband modem to the WAN or Internet port, the computer to an available numbered port and powering on the router check the lights on the front panel of the router. For instructions, click here.
After checking the router's LEDs, configure the router for cable Internet. For instructions, follow the steps below.
Configuring a Linksys Router for a Cable Connection
kb4682-002_en.png For Telstra Cable internet users, please contact Telstra to confirm if your internet connection is using DHCP or HB (Heart Beat) signal. There should be no other machine running HB client upon doing this procedure.
Step 1:
Access the router's web-based setup page. For instructions, click here.


NOTE
: If you are using Mac to access the router's web-based setup page, click here. If you forgot your IP address, click here. If you forgot your router's password, click here.


Step 2:

When the router's web-based setup page appears, click the drop-down arrow under the Internet Connection Type field and select Automatic Configuration - DHCP.
(a) If you are NOT using Telstra HB, proceed with DHCP setup.

NOTE: If you are a Telstra Cable internet user and you're using WRT120N, WRT160N v1, WRT320N or WRT610N, please select Telstra Cable.
(b) If you are using Telstra Cable, proceed with the following setup. Obtain your user name and password from Telstra. Please disable any HB client that might have been previously running on the PC after thcable modem internet works when - kb4682-004_en.pnggured.

Step 6:

Click kb4682-012_en.png.


Step 7:
Click Status. Check the value of the Internet IP Address. If the Internet IP Address has numbers, this means the router has been properly configured. You should now be able to access the Internet. If you're not online, perform a power cycle to synchronize the router with the modem.

NOTE:
If the Internet IP Address is all zeroes (0.0.0.0) click kb4682-008_en.png first then click kb4682-009_en.png. If the Internet IP Address is still all zeroes (0.0.0.0) perform a power cycle. For instructions, click here.
If the IP Address starts with 192.168.1.xxx or if it has the same first three numbers (octets) as the router's IP address, change the router's LAN IP address to a different LAN segment. For instructions, click here.
Once the router is configured, perform a power cycle. For instructions, follow the steps below.
Power Cycling

Step 1:
Shutdown the computer.

Step 2:

Unplug the router's power cable.


Step 3:

Unplug the Broadband modem's power cable and wait for 30 seconds.


Step 4:

Plug in the Broadband modem's power cable and wait for its lights to appear stable.


Step 5:

Plug in the router's power cable once the modem's lights appear stable.


Step 6:

Power on the computer on and test the Internet connection.
NOTE: If you're not online after performing this procedure, you may need to upgrade the firmware of the router.

SOURCE: Connecting Laptop wireless and Desktop wired to the router

Do you need to see the desktop or just share folders from each other? If the latter then you need to do the following:

Use Windows Explorer and select a folder you want to share. Right click and select sharing and security.

On the sharing tab click on Share this folder. Enter a share name ( I like to enter the PC name _folder name; Rick1_Downloads)

Click on Permissions. If your ok with everyone using the PC's and Laptops having access then highlight Everyone and click on Full Control.

Do this on each PC and Laptop.

That should be it or darned near close.

SOURCE: Belkin 54g Router won't connect to internet.

If you can access the configuration page of your belkin router you have to copy the MAC address of your computer to the router. The router has the capability to clone the MAC address. It's because if you have a cable internet connection the MAC address is registered in the server.

Just installed win 7 and can't get internet on


Can't connect to the Internet using Windows 7 OS.
1. If you haven't already done so, run the Network troubleshooter to see if it can help diagnose and solve your problem.
Open the Network troubleshooter by right-clicking the network icon in the notification area, and then clicking Troubleshoot problems.
2. Make sure that all cables are connected (for example, make sure your modem is connected to a working phone jack or cable connection, either directly or through a router).
3. Restart your modem, and then restart your router. Remove the power cable from the modem and router. After all lights on the device have gone out, wait at least 10 seconds, and then plug the modem and router back in. Some modems have a battery backup that prevents the lights from going out. For this type of modem, press and quickly release the Reset button.
4. Check your router. Because of the new networking features in Windows Vista andWindows 7, some older network routers are not fully compatible with these versions of Windows and can cause problems. You can test your router to see whether it is fully compatible with Windows 7 by running the Internet Connectivity Evaluation Tool. Or, for a list of routers that are compatible with Windows Vista, go to the WindowsCompatibility Center website.

Internet no longer working, but internal network is fine.


i agree with all the above.. it's definately clear as mud how the network is designed and or funtioning. The machines connected to the wireless d-link router.. are they via cat5 inthe wired ports or wireless ? is the server the machine thats connecting to the switch and wiress router and modem? i'd say reset all switches modems routers and machines.. shut them all down.. then fire the cable modem, then the wireless router then the desktop switch then the server, the workstations and the one lonely wireless.. run "ipconfig /all" on all machines and if they aren't all sharing common ips and access, provide the results here for further investigation.

Router won't log into it's IP address online


It appears to me that you have everything plugged into the desktop PC. This is not the way that it should be done. Plug the cable modem into the wireless router via the Internet/WAN port. Plug your desktop PC into one of the ports numbered 1-4. Now connect to the router via the wireless connection for the router and you should be able to now connect to the internet with your laptop.
If it still does not work, power down everything in this order: Laptop, Desktop, Router, Cable Modem. Bring everthing up in the reverse order (Cable Modem, Router, Desktop, Laptop) waiting for each device to stablize before moving to the next.
Once you get everything working, turn on your wireless security (WPA not WEP) asap to keep your computers and surfing safe, and to keep intruders off your network.

Server not found} NetGear WGR614 Wireless Router doesn't connect me to the internet.


Dear Loud Nouises,

Your router must be connected properly to the cable modem. This must be to the wan port on the router.

Next, the router must be set-up accordingly to recognize the modem's internet connections. Please ask for the IP address.. and other relevant informations from your internet provider.

Set -up your computer using the internet connections wizard on each of your respective computer.

This should work fine if all connections were correctly configured.
