Suddenly today after working for a couple of years all the lights are on solid and my wireless laptops can not find the router

To connect to your wireless network using Vista's WLAN Autoconfig, follow these steps:
Step 1:
Right-click this icon at the bottom-right corner of the screen and select Connect to a network.


Step 2:
Select your Wireless Network Name then click Connect.

NOTE: If the wireless network name or your SSID is not listed, the SSID Broadcast on the router might be disabled. For instructions on how to connect to the wireless network with the SSID broadcast being disabled, click here.
If the computer is not detecting any signal or is not seeing any wireless network, change the channel of the router. For instructions, click here.
If WEP/WPA is enabled on the router:
Step 3:
Enter your wireless network WEP/WPA Key on the field provided then click Connect.
NOTE: To learn more about WEP/WPA and other Wireless Settings, click here.

NOTE: Make sure Display characters is checked, to display the WEP/WPA key used by the router. You can get the passphrase or network key from the encryption that has been generated (if using WEP network security) from the router's web-based setup page. If you're using WPA network security, the network key is the key for passphrase.

Make sure you enter the wireless network's WEP or WPA key not the Passphrase.

It is also possible to make a wireless connection even if the wireless security is disabled on your router. If you don't see any network SSID from your network list, make sure your wireless adapter/device is ON and your router is in good condition. If your router shows any unstable occurrence, click here.
