Well I think the router (Netgear wndr3400) may be firewalling my connections and I need to disable 1 or both. I saw the spec's said dual firewall, I will need to disable both if that is the case

I cannot connect my skpye to the internet and thinking it may have something to do with my netgear wnr 1000 router. How do I allow it to access the internet?

option 1. check your firewall setting maybe it prohibits skype from accessing the internet. check if you have other firewall programs then check the settings. if it is ok try to disable your firewall.
option 2.try if you can use your internet connection without using the router then try using skype. if it works there is problem with the router settings. if not your problem with the skype try to reinstall it.

Hi, i have the same issue and it isnt the firewall. But here is how to disable it if it is. Go to the router websight at 192.168.0.1 (type this directly into the browser bar at the top of your page. The password is usually password in lowercase. The username is admin. This will get you into the management screen for the router config. Look on the Left and you will see firewall. Click on this then ensure that there are no restrictions for HP.

I still have the issue with the printer so good luck.......scotty
