Dear all i just have bought a new P4 Dell System. It is working really nice for me. Some days before i have got a telephoen connection in my home , so i thought to connect internet. I purchased a new modem MODEL AMBIENT MD5628. My telephone line is very clear and modem is also new but my internet disconnects again and again after each five mintues. Although modem is installed but in DEVICE MANAGER there is an option named as " OTHER DEVICES" which shows an unsupported device. PLEASE ANYBODY HELP ME
