Ok, do a troubleshooting session.
Unplug the router from the internet modem.
Try at first to connect using a Network cable from you PC to one of the LAN sockets.
Can you access  with your web browser?  (the configuration page)
     If yes it is possible that the router has the same address as your adsl modem.
    change the router address to something instead of
     Save your changes. Plug your WRT to the adsl modem and try again.

     Does the internet work now with a wired connection ?

If the above does not work can you "ping" the machine ?

if none of that works try doing a hard reset... heres a little guide (off the DD-WRT wiki)

My linksys w/2phone ports cannot hook up with the ethernet

Most Cable Internet Service Providers (ISPs) use Media Access Control (MAC) Address authentication to establish Internet connection for end-users. MAC address is a unique identifier assigned to the network adapter/s of the computer.
To set up your Linksys router to work with a Cable ISP, you have to enable the MAC Clone feature of the router. MAC Cloning is a procedure which enables a router to copy the MAC address of the computer registered with the ISP.
To set up a Linksys router with Cable connection, you need to perform four steps using the computer that's been registered with the ISP:
i. Verifying Internet Connection
ii. Connecting the Devices Together
iii. Checking the Router's LEDs
iv. Setting Up a Linksys Router for Cable Internet Connection

Verifying Internet Connection
Connect the computer to the Broadband modem using an Ethernet cable without the router installed. If you cannot get online, contact your ISP. If it's online, use the computer to set up the router.
NOTE: Some cable modems use the USB port. If the physical connection is via USB port, you may not be able to go online via Ethernet connection. Contact your ISP to have the Ethernet port of the modem configured.

kb17251-001_en.png NOTE: The image may vary depending on the computer and modem you're using.
Connecting the Devices Together
After confirming the Internet connection through the modem, connect the modem to the Internet port of the router; connect the computer to any of the four Ethernet ports at the back of the router. For instructions, click here.
Checking the Router's LEDs
After connecting the devices together, check the lights on the front panel of the router. Ensure that the Internet light, as well as numbered light corresponding to the Ethernet port where the computer is connected, is lit. For further instructions, click here.
Setting Up a Linksys Router for Cable Internet Connection

Step 1:
Access the router's web-based setup page. For instructions, click here.

NOTE: If you are using a Mac computer to access the router's web-based setup page, click here.

Step 2:
On the Setup tab, click the MAC Address Clone sub-tab.


Step 3:
Select Enabled then click Clone My PC's MAC.


Step 4:
Click Save Settings.

Step 5:
Click the Status tab.


Step 6:
Check 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 still unable to access the Internet, powercycle the modem, the router and then restart the computer.


NOTE: If the IP address is still, click IP Address Release then, click IP Address Renew. If this does not change the IP Address, powercycle the modem, the router and then restart the computer.

I cant install my router. The internet, power, WLAN, and DMZ lights are all on, but none of the Ethernet port lights are on, but when I try to complete the install I get the following error message: Unable...

If the ethernet light is not coming that means your router is not detecting your computer. Try to plug the computer on any other port.

To check if your ethernet ports are fine you can perform a loop back test. You can take a cable which is not connected to anything. Than put one end of the cable to one ethernet port and put other end of that same cable to any other ethernet port. If the light on the ethernet ports led up means your ports are fine and u need to reinsatll the drivers of the ethernet card on your computer. Else your routers ethernet port are not functioning. If that is the case you can try to reset the router.

Let me know your finding.

**If this works please rate else let me know in case of further help.**

I recently got a Mac desktop and my Linksys router disk will not open up. Do I need a router that is made for Macs or is there a way to configure the Linksys?

Hi, You are correct. The CD is not compatible with Mac. What you have to do is Configuring the Router Manually using the Web Based Configuration panel.
How to:
  1. Open your Web Browser
  2. Type in the Address Bar and hit Enter
  3. If you have changed the address somehow you have to enter that (Router's IP - Default Gateway)
  4. Here is a small guide to Fine your routers IP address in case of that you are unable to access
  5. Enter the user name (default user name is blank- means no user name. Just leave it blank), Default password is admin.
  6. Now you can configure the Router using the Menus.
  7. Make sure that you have Saved your settings before Exit the Web Based Setup.
  8. Make sure that you have changed the Default Password.
  • If you can’t access the router’s web-based setup page, please check the following: cable connections, router’s LEDs, IP address, and connectivity.
  • Connecting Devices Together
  • Ensure that you have an Active Internet Connection and connect the modem to the router’s Internet port and the Mac to any of the four Ethernet ports.
  • Checking the Router’s LEDs
  • After connecting your modem and Mac to the router, check the lights on the front panel of the router.
  • Checking the Router’s IP Address
  • To find a Linksys router’s Local IP address, you have to check the IP settings of the Mac
  • Checking the Mac’s Connectivity with the Router
  • Ensure that the Mac is properly connected to the router.
You can download the Manuals from here to learn how to do Advanced, Customized Configurations.
Note: Please select the appropriate Hardware Version.
Thanks for contacting Fixya! Feel free to ask any questions if you face trouble with the setup. Please rate the answer as well!

All routers need to have a ethernet cord from the ISP Device. Most people run Laptops Wireless from there routers or if its stationary run another ethernet cord from an open port behind the router to your laptop.

Error 321 'ethernet not connected' on LINKSYS WRT54GS

Dont go with the error , i came across such instances on a few occasions while users were installing it from CD . (Sounds lamme?right)
Try doing the set up manually , by accessing the web Gui of router .
***FOLLOW THIS********
The GS comes set to as its factory default and with its built-in DHCP server enabled. So all you'll need to do is plug in a client that's set to obtain its IP address information automatically, maybe do a DHCP release / renew (or reboot your client computer), and enter the default password into the login box that pops up. If all goes well, you'll get the main Setup screen.
The Internet Configuration Type selector automatically refreshes the browser screen to present settings appropriate to the choices of Automatic Configuration - DHCP, Static IP, PPPoE, PPTP and Heartbeat Signal (for Australian users) Internet connection types.
MAC address cloning gets its own page in the Setup section, as does setting up either dynamic DNS service from or TZO, setting up static routes or disabling NAT features and converting the GS to a non-NAT router.
The interface is generally quick, with quick mini-reboots needed to get the changes you make on each page to take. Multiple admin logins are allowed, with no warning given when two or more admins log on. Once you're logged in, there's no idle timeout, and you just need to remember to quit your browser when you're done, because there's no logout button.
Enabling Remote Management for the first time still pops up a message telling you to change the router's default password and you can now enable secure (HTTPS) admin access. You can also change the default remote admin port from 8080, but can't restrict access by IP address or domain. Also of note is that you can't reboot the GS from the Admin interface.

Let me know if you require any more assistance.

The port of Linksys Wireless-G WRT54GS Router Linksys Wireless-G WRT54GS Router

What do you want to know about the ports? The one separated from the other ports is the Internet port. that is where you're going to connect the cable from your modem. The other four are the ethernet port where you will connect the computers.

Connecting a linksys wrt54g to a netopia modem

Is this an ISDN modem?

Generally: Netopia Ethernet out -> Linksys WAN port with a standard ethernet cable.
(Not the yellow LAN ports! - They are for your computers/printers.)

Trying to turn a Linksys WRT54GS into a hub

  1. If you want to set the router to work only as a switch with wireless access point, you may need to get into its setup page and adjust some settings.
  2. Using a computer that is wired directly to one of the router's Ethernet ports, launch IE and type It is the default IP address of the router. Then it will open a window, asking for a username and password. By default, there is no username and the password is admin.
  3. Once you're in the router's User Interface, look for a sub tab called "Advanced Routing" under the main tab SETUP. Then set router mode to "Router" instead of Gateway. In some router's, the choice there is NAT enable or disable. If it is the one showing there instead of Router mode, then set NAT to disable. Click Save settings which is located at the bottom portion of the screen.
  4. Then click on "Basic Setup" and then disable DHCP server. Save the settings then.
  5. Then your modem now will be connected to one of the 4 Ethernet ports of the router.
Hope this helps!

You didn't specify if you're using DSL or cable internet.

With DSL, keep in mind the software1.gif on the PC is what "dials out" to the ISP with your name / password, and you MUST set the name and password in the router. Otherwise, ONLY the computer that has the software installed (verizon, etc) will be able to connect.

Also, make sure that ONLY the LAN is connected from the router to the modem, and not both the USB and LAN.

If you're using a cable connection, you don't have to do this, however, most newer Linksys routers come with a 'setup' disk, which MUST be used regardless of connection type.
