I'm connected via wifi to my ISP's router/modem. While Windows says that I'm always connected, I keep getting messages from Netgear Genie that I've lost contact to the Internet, and I cannot access webpages until it comes back.

There are two other computers in the house, one connected to the router via ethernet, the other via wifi, both seem to have no such problems.

I've wondered if Netgear genie itself was the problem, but I am regularly disconnected even if I uninstall it. And I'd rather have it since it accurently tells me if I'm connected or not.

1. Why does windows says I'm online if I can't access any online game, or website ?
2. Is "netgear genie" the problem ?
3. I've removed the connection, recreated it, I've even copied the settings to a usb key from the computer that has wifi access.
