Hi frnds...This is just to inform u all that it is very easy to know anyones username n password in DataOne.So for security purpose do follow these steps or ur account can be hacked anytime. Thn b ready to pay heavy bills.1. Avoid keeping ur username n password in modem firmware for always on internet, and if u prefer that just change the default password of ur login screen of ur modem page wic is by default 'admin'. Do change it.2. Better is to use the bridge mode rather than PPPOE. So create an account in network connections. 3. Always connect ur internet after u on ur PC frm netwok connections... if u hav created ur account in there.4. Do change ur account password once in every month.I hope u will follow this so that u might not face any problems.
