Gateway profile 4 ,need to get the ethernet controller to get the LAN to work.

1 Remove power from the Gateway. 2 Disconnect all your computers and the cable/DSL modem from the Gateway router. 3 Using a straight through Ethernet cable, connect the Ethernet Cable/DSL port on the rear of the Gateway to any one of the LAN ports. 4 Re-apply power to the Gateway. The Alert LED will flash as the Gateway starts up, and after approximately 30 seconds will start to flash more slowly (typically 2 seconds on, 2 seconds off). Once the Alert LED has started to flash slowly, remove power from the Gateway. 5 Remove the cable connecting the Cable/DSL port to the LAN port, and reconnect one of your computers to one of the Gateway LAN ports. 6 Re-apply power to the Gateway, and when the start-up sequence has completed, browse to: http://192.168.1.1 and run the configuration wizard. You may need to restart your computer before you attempt this. 7 When the configuration wizard has completed, you may reconnect your network as it was before

Since your wireless is working, the missing driver is for your ethernet port. Go to gateway support driver download (link below). Select your computer by following the on screen prompts and download the driver for you LAN port.

Telephone wall-plate <---- 4-strand telephone-cord ---> telephone-port in modem

AC power from wall-plate to modem.

LAN port #1 <--- Ethernet cable --> network-port on desktop/laptop computer #1.
LAN port #2 <--- Ethernet cable --> network-port on desktop/laptop computer #2.
LAN port #3 <--- Ethernet cable --> network-port on desktop/laptop computer #3.
LAN port #4 <--- Ethernet cable --> network-port on desktop/laptop computer #4.

Configure the router's wireless adapter:
* set a SSID
* set an encryption-level, e.g., 'WPA'
* set a network password

Use the SSID/password to configure your wireless devices (iPod Touch, iPad, XBOX 360, etc.)

You may download the LAN and all the other Drivers from the below link:

Select the exact Model # of the Computer and download the Drivers.

Hope this helps.

That may not help.

Try this address as most routers can be assessed by it:
www.routerlogin.net

Should that not work try these steps which should definitely work:
For XP:
1) Go to Start, then click Run.
For Vista:
1) There should be a key that looks like a Flag or the Windows Symbol, hold it and press R.
The following is for both OS's.
2) Type in cmd and hit enter.
3) Type in ipconfig and hit enter.
4)
>For Ethernet Connection:
look for Ethernet LAN adapter and under it for Default Gateway.
>For Wireless Connection:
look for Wireless LAN adapter and under it for Default Gateway.
Note down this address and this is what you put into the browsers address bar.
Note: There will be more after Wireless LAN adapter and Ethernet LAN adapter but that is the start of the entry you are looking for.

This should get you to your routers login interface. If nothing is there or it is 0.0.0.0 you need to probably either check your connection to your router or try resetting your router by unplugging and plugging it back in or using the reset button.

Hi! Absolutely, the Gateway Router is OS independent. All you need is a computer with a properly configured Ethernet LAN adapter and a web browser to configure the Gateway Router. Any platform that supports Ethernet & TCP/IP is compatible with the router. You may need to provide additional hardware & software (i.e. Ethernet cards and/or software drivers) to ensure that all clients operate with the router.

you are right, need cd for you lan card for it to work right,,but if you dont have it go to linksys web site and download the files you need

click start
click connect to
show all connections
look to see if lan or high speed internet shows connection.
If enabled and not working look on back of computer to see green light from ethernet plug.
if no green light try different ethernet cable, if that doesn't help replace ethernet card less than $20

if you need more let me know
