u all who read this must understand what "ISP" stands for. As an Internet Service Provider, all they can do is to give internet access to customer. n they manage to give it. the problem is about that modem. the D-link modem. they should be blame bcause they set the default settings. i think TM have no rights to change the default setting except the one that has to do with internet access.

about the question on can people change the modem..... i think they cant.... bcoz it has something to do with the main equipment at TM office n MAC address of the modem(my friend at TM told me). so if u n ur neighbour both subscribe unfi, their modem cant be exchange eventhough they have the same modem brand....

try to google about the d-link modem to find more answers
