Try disabling the LAN Connection that you unplug (NOT the wireless LAN) and then do an IPCONFIG in the command prompt.

have you setup your network Key?

right-click on the icon in your taskbar (lower-right side), and then select 'view available wireless networks', then select the your wireless connection and hit 'advanced', is there a place to insert your network key?

look at this previously asked question:

What Lime is trying to point out is that if you disconnect the wire, it might still have a valid IP address, and the machine will try to use it (and will fail miserably because it's not plugged in).

If you go to Start, Control Panel, Network Connections (I think, I'm not on an XP box right now) you should see listings for your wireless and your wired.  The are likely called Lan Connection #1 and Lan Connection #2.  If you look at the details of them you should see what the actual card is.

If you right click on the wired connection, one option should be "Disable".  That should eliminate any "conflict" between the two cards.

1)wireless connections 2)lan connection
but on the lan connection it has a red cross mark (which i think it is disabled) but not on the wireless connection.

Mine is DI-624 D-Link model.

No, the red cross means that it's not currently connected.  If it's disabled, it will "grey".

Right click on the Lan connection, and choose disable from the context menu.

Wait a few seconds, and you should see it grey out.

If you want to double check, right click again, and enable should become a choice, while disable will be greyed out.

After the lan is disabled, hit Start, Run, and type "cmd" into the box, then click OK.

You should now be at a command prompt.  Type "ipconfig" and push enter.

You should see your IP Address for your wireless card.  If it has one, try getting to the internet.  If it is 0.0.0.0, then type "ipconfig /renew" and hit enter.  It should come back with an IP address (might take some time, but less than a minute).

If it does not, then we're barking up the wrong tree, and as ngravatt pointed out, you probably need to set your WEP key up.  I don't know if D-Link is turning it on by default now or now (won't touch D-Link myself).

i tried everything but still not working. Everybody is saying have to configure centrino technology on my IBM laptop.
Let me know what else i can configure?

After i take off the wire between laptop and router and restart my laptop and see the ipconfig, it has changed from 192 to 169.

Any advise is helpful.

Nandi11,

You can't really configure the Centrino technology... that is just Intel's marketing word for wireless with power saving doo dads.

It is good that your IP changed from 192 to 169.... the 169 address is Windows' default IP address when a connection to a DHCP server is not found.  This means that your computer's LAN connection is off.

Follow ihuckaby's suggestion...

1. Right click on the LAN icon and choose disable (Leave the WIRELESS icon alone).  Wait a few seconds and the icon will change from color to gray.
2. Then goto the command prompt and type in IPCONFIG /RENEW
3. Your router should give you a new IP address as 192...

A WEP key won't be required since you are getting an 'Excellent' connection on your wireless already ... in the future you should setup some kind of encryption for your own privacy and to prevent rogue wi-fi connections.
