Yeah i have Cox communications. And i believe they dont use PPPoE. So I changed it like gamehead said. Didnt work, shut down my whole internet. I then had to change my IP to 192.168.1.101 my internet then work again. So i change th IP back to 192.168.1.1 and it worked to. Ive reseted my router about 500 times. Ive diconnected cables, reset it, unplug the power. Ive dont just about everything. But i will try and download Firmware 1.45.7
