Have Linksys WRT54G2. All port led's are lit and

Disconnect the power to it, wait 5 minutes and power back on.

Note that incoming traffic will cause the WAN (or Internet) light to blink even if it is 'probe' traffic trying to break in to your network. Such traffic is to be expected and is the reason you have firewall functionality in your gateway router.

On the inside, there is a bit of traffic on any LAN when the computers are turned on. Messages generated by the router itself are used to find computers and printers for a lot of different legitimate reasons.

That router must have got a lot of water in it and powered on thats why it has shorted and all the lEDs on it are glowing. Last resort before dumping it (beyond economical repairs) is to give it a factory reset.

Sometimes, you might face a situation where your wireless icon shows that you are connected to the Internet but you just can't access any websites. What do you do when you face this problem?

This article will show you how you can repair Internet connection when wireless icon shows connected, but unable to go online.

In checking if you're computer is properly connected to the Linksys Router, you will need to perform four steps:
i. Checking the Physical Connection to the Router
ii. Checking the LEDs
iii. Checking the IP Address of the PC
iv. Pinging the Router
NOTE: To check the computer's connection to the router using Mac, click here. If you are using Windows Vista, click here. For Windows 7 users, learn more here. For Windows 7 users, learn more here.
Checking the Physical Connection to the Router

Make sure that the computer is connected to one of the four Ethernet ports of the router and the modem should be connected to the Internet port. For more instructions, click here.
Checking the LEDs

The Linksys router's LED lights will indicate the status of the connection. After connecting the broadband modem and the computer to the router, make sure that the LED lights are lit up. For more instructions, click here.
Checking the IP Address of the PC

The IP address of the computer is another indication that the computer is properly connected to the router. For instructions, click here.
Pinging the Router

Ping test helps trace the communication between the computer and the router. The computer sends packets to the router and in return the router sends out replies to validate the connection. In this example, our router IP address is "192.168.1.1."

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.

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 0.0.0.0, 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.

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.

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, the following should be lit:

• 1 - 8 (LAN)
• DMZ/Internet (WAN2)
• Internet (WAN1)
• Diag
• System

Checking the Router's LEDs
Step 1:
Make sure the System LED is lit.

NOTE: If the Diag LED doesn't goes off, you need to upgrade the router's firmware. For instructions, click here .

Step 2:
Make sure the LAN 1-8 ports is lit depending on the computers connected to the designated Ethernet port.

NOTE: If the LAN 1-8 port is not lit, make sure that the computer is powered on. You can also try connecting the PC using another working cable.

Step 3:
Make sure the Internet (WAN1) and DMZ/Internet (WAN2) LED is lit.
NOTE: If the Internet or DMZ/Internet LED is not lit make sure the Broadband modem is powered on and that the modem is properly connected to the Ethernet port

You can access the web-based user interface utility of the RV082 by using one of two methods:

• Through the RV082 IP address (192.168.1.1 by default), or
• Through its default hostname ("RV082")

1. Open a web browser (Internet Explorer or Netscape Navigator)

· By IP address: Type http://192.168.1.1 (192.168.1.1 is the default IP address of the RV082)

and click Go or press the [Enter] key.

· By Hostname: Type http://RV082 and click Go or press the [Enter] key.

2. When the username and password prompt appears, type admin in both the username and password fields. (admin is both the default username and default password for the RV082).

The Linksys WRT54G2 is Cable/DSL router with 4 port switch. It has many features including a built-in DHCP server. By default, it's IP address is 192.168.1.1, username: blank and password: admin.

Plug in the Modem to the Linksys router's Internet / WAN port then plug your PC's to any of the 4 ports (1,2,3 & 4). The Linksys router once turned ON will automatically provide your PC with IP address starting with 192.168.1.xx (x means number from 100-149).

Make sure that known working ethernet cables are being used. Check your computer's IP adress by going to the command prompt. Start>RUN>type CMD then press Enter. Type IPCONFIG and check the IP address (e.g. 192.168.1.100). Check you PC's network adapter if you don't get an IP address from the Linksys router.

You may opt to reset the router by pressing the reset button at the back for 30 seconds if it fails to give out DHCP.

Cheers!

Connect the cable from the LAN port on the DSL modem to any of the 4- LAN ports on the Linksys Swicth (not the port Labelled Internet), then from any of the remaining 4 ports then connect your computer. Also try using a cross-over cable to modem from the DSL LAN port to the Linksys.

Im not sure but you could try this?
1)Get on your computer 2)Press Start>Run 3)then type cmd 4)Type ipconfig then hit enter 5)Type ipconfig /release then hit enter 6)type ipconfig /renew then hit enter 7)try your internet
