Hi, I have bought the modem from Best Buy and brought it to Turkey to use with Turksat's Uydunet Cable service. We have called our Cable service provider and gave them modem's MAC address. They have added it and we were able to get signal. But the modem can not get an IP from the service provider. Also we can not change the Country setting in the modem. Our old modem, which is Netmaster CBW-383Z4, works fine. I have contacted ARRIS but they did not help.
