I'm experiencing a really strange situation.

My laptop all of a sudden can only connect to the home wifi "local only" and cannot reach the internet. It was fine even a couple of weeks ago. It is a lenovo and runs on Vista. I've tried Vista's "Diagonse and Repair" and "Network and Sharing Center" to no avail. Rebooting doesn't fix it.

This is all the more strange because,

  • ■all the other wifi devices at home - iPad, wifi music players, smart TV, etc - can connect to home wifi and reach the internet
    ■my laptop can reach the internet when being connected to third-party wifi networks, such as my work or hot spots
    ■when I wire my laptop to my home router with lan cable, then the problem goes away and my laptop establishes internet connection

I've done a fair amount of internet search and couldn't find any answer. Any idea why this is happening?

Unfortunately, the interface to the router doesn't allow me to change the channels. I have Verizon Fios, and the embeded-web server on the Actiontec router - which I access by going to 192.168.1.1 - has no setting for channel selection.
