I have a Netgear N750 Dualband gigabit router. Earlier today it was working absolutely fine. All of a sudden, I cant connect to anything. My skype contacts will only load about 5 of them, then no more, as to when i switch to the comcast modem, it loads them all. Sometimes it will show its loading a webpage, but never does, and then sometimes it doesnt even do that. Please help me fix this. thanks!
