Nice to know how an AT&T technician can just blame it on the customer's equipment when he said it himself that he's not an IT person (he's the 'line guy'), claimed to have never seen NVG510 before, never encountered this issue until he came to the house, doesn't even know what ping is nor that Internet Explorer, which I have but don't use, looks slightly different on a Mac. So, the technician came today and said there's nothing wrong with the phone line, checked the modem, reset it the way I always did, and suggested that my computer AND cellphones must be the ones having the problems because everything seems to work just fine. After the last attempt just few days ago over the same issue, the tech support suggested that a technician come to see if there's a connection issue OUTSIDE the house, and I agreed because I was frustrated and thinking that a new modem may not fix the problem. When it happened after office hours, I resorted to resetting the modem. On a couple of occasions, the tech support reset from AT&T end followed by my restarting the computer it did not fix the problem until I reset the modem myself. I use MacOSX (Safari & Firefox), and a couple of cellphones (running on Symbian v5 and Android) to wi-fi, did add google DNS to the System Preferences/Network, turned off IPv6 on AT&T GUI page, yet every week I called tech support to find out what's with the 'Potential Connection Issue'.
