Fail to connect to home wireless network?

I have laptop "IBM ThinkPad T41" with build-in wireless adapter, "Intel(R) PRO/Wireless LAN 2100 3B Mini PCI Adapter", it has no problem to connect to my home wireless network (Linksys router), it worked fine until yesterday, when I rebooted DSL modem, wireless router and my computer, after that it would not make connection, but if I use Linksys wireless card for laptop, it has no problem to connect. I wonder how I can debug and find out what is wrong? where I should look at? any log file I can examine? Thanks.

2. Maybe your wireless network name was reset and your one adapter isn't set to that name. I'd try to change it to the name that you have set up on your router.
3. it could be that when your rebooted everything some of the settings were lost. They shouldn't be but it can happen sometimes. Also it depends where you are in the house, it might be that your in a part of a room that doens't get good reception although this is less likley. Check that your laptops inbuilt wireless settings for ip address set so the ip address is assigned from the router and not set by windows.
4. sounds like your internal wirless is holding on to the old IP address. When you rebotted the router it was given a new IP address ( assuming your using DHCP and not a static IP) You need to release the IP. IBM probably has some software to do the trick, but if not here is a generic step. Reboot the IBM (make sure the Linksys card is OUT!). Got to Start, Run, type CMD Then enter. This will open a DOS window Type cd\ and then hit enter This will take you back to the root drive. Then type IPCONFIG /RENEW_ALL and hit enter that will release the IP address. Then type IPCONFIG /RENEW and hit enter This will renew the IP to match the router. Then type Exit and hit enter. You should be good to go. Good luck!!
