Firewalls installed? Try disable for testing and make a test, see if you can connect to your network using wireless with firewall disabled.
When you click on what? (I don't understand here what you want to do: you click on a link to a web page?)
What is the content of c:\outipcfg.txt from your laptop?
(Do so:
Start->Run->cmd
ipconfig /all >c:\outipcfg.txt
copy the content of outipcfg.txt here)

Well the problem is that your wireless isn't getting a proper IP.
169.254.249.255 is the IP windows assigns when no other is available.
If windows is telling you you're connected to your wireless network, try right clicking the wireless network icon in the taskbar notification area and select repair.

Set the default gateway to the routers IP address.
