I don't know what happens, I'm starting to think that it's a defective router, because the limewire of my friend can't connect to the Internet, I have the same router, I tried to connect using my limewire on my laptop and didn't work neither.
My router is the same, but version v5 and it works perfectly. I already tried everything, port forwarding, static IP and nothing works, it's not the ISP because when I connect my laptop straight to my modem it works too, even in his house, we both live in CA and have Cox Cable. Did anyone have ever experienced this problem. Ah, he said that everything was working fine and suddenly stopped.
Thank you all for your attention!!
