My internet connection is behaving weird?

[usrkdn_98]

AT&T uses DSL. A DSL modem will loose it's connection or reboot if the Signal To Noise Ratio on the line gets too low. This allows other influences and traffic in the cable to confuse the DSL signal so your modem cannot do anything with it. When this happens, it will reboot and, for a short time it may work again. There may also be other issues in their equipment including the network interface. Any loose or temperature sensitive connection can make it go down also such as outside (or inside) temperature or humidity changes, any corrosion on a connection etc. When I was installing DSL and troubleshooting, we used a SNR of 12 which by other companies standards is high but, the higher the better. A SNR of 6 will run but that's only if everything in the loop is perfect all the time. The distance you are from their DSLAM (origin of DSL) effects it also. The farther away you are the lower your speed will be and, if they are pushing it too far, that will hurt it also.
