Recently, my UTStarcom ADSL modem has developed a problem: When I turn it on, it will work for a minute, and then stop. I will then have to reboot it for it to work again. But it will stop again after a few minutes. I will again reboot. this process has to be repeated quite a few times for it to work continuously. Then it can work for hours without any problems. Why is it like that? What can I do to correct it? Any help will be truly appreciated.
