Not able to pick up wireless signal on my laptop

Can you connect to the Internet using the LAN cable?
Have you configured the wireless card in your laptop with the router's wireless settings?

Network Key (WEP, WPA, WPA2 Encryption key)To connectyour computer to a wireless router, you click the Refresh networklist, then Choose your wireless network and then click Connectto your secured Wireless Network, it will asks for a Network Keybefore allowing you to connect into your wireless network. This NetworkKey is either the WEP, or WPA or WPA2 Encryption key that is used toconfigure the Wireless Router. The Passphrase is an alternate way tosetup the Encryption key.
When you are requested for a Network Key, you can just enter the Passphrasethat was used to configure the Encryption key in the wireless router.http://www.fixya.com/support/r5270415-network_password_network_addressFor information on securing your wireless network,configuring the wireless router and configuring the wireless card in thelaptop/computer, please click on this link and follow my instructions :-http://www.fixya.com/support/r3559128-wireless_router_security

Hi,

Please power cycle the router by unplugging / plugging the power cord.

Try changing channels; default is 6; try 1 or 11.
Change your SSID: personalize it
SSID broadcast: Enable

Check the advanced wireless settings and make sure MAC filtering - DISABLED.

Reset the Linksys router by pressing RESET for 30 seconds should everything fails and re-configure. Firmware is another consideration BUT this is just a new release.

Regards,

Angel

you can use the WinSock XP Fix tool to reset TCP/IP protocol to original state: http://www.snapfiles.com/get/winsockxpfix.html

Is your desktop getting an ip address from the router?
You said that you reset the router, do you mean turning it on and off or pressing the reset button?

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.

try opening network connections disable the default connection and enable linksystems

Are you located near any other sources of 2.4Ghz interference - cordless phones, baby monitors, microwave oven, like that? I find I have plenty of signal strength but then suffer random drop-outs when my cordless phone is in line-of-sight between the laptop and the wireless hub.

There are several problems reported that may cause disconnection. First is the hiding of the SSID (wireless network name) and enabling WEP or WPA encryption. The recommended solution for that is to unhide the SSID in the router configuration.

Second is that there are more and more wireless devices and occasionally interference occurs on a single channel (even from non computer devices like wireless phones. As routers are often set to channel 6 you may be competing for radio communications with your neighbors. The recommendation is to switch the router to either channel 1 or 11. If your first choice does not work try the other.
