I have a BSNL Dataone Broadband connection with Huawei WA1003A Wireless Modem. I face this problem many times, sometimes ADSL light is turned on the modem but there is no internet connectivity. I called the customer care and those people told me that it's a modem problem and advised me to get the modem changed. Is it true? Can it be a Modem Problem. I have this modem since 6 years.
