Norton Internet Security problem with wireless

Hi,

I'm having a problem with Norton Internet Security and two wireless connections. All three PCs (two desktops and a laptop) have the same security but the one wireless desktop and the wireless laptop are stopped from accessing the internet. If I connect with a wire, no problem. As soon as I turn off the Norton personal firewall, I can connect. Turn it back on, bye bye internet. I assume there must be a configuration setting, that I can't find. Any help would be great. Not that it makes any difference but, the router is a Netgear WPN824 Rangemax and the wireless adapters are also Netgear Rangemax generation.


Thanks...Vince
