after i called twice this morning and afternoon TM Careline complaining about slow connection, the line is now back to normal.
1st call the lady reset my port, but still very slow, only 200+kbps
2nd call on afternoon, its a guy who answering. he just ask some simple question and i tell him my problem. he just told me everything is fine and im getting a good IP range which is 60.53. he even told me alot of ppl is looking for this IP. but still, its slow~

nothing can be done, he just suggest to restart my port again, but i said let it be and i'll monitored the situation since im getting a "good" IP.
then after an hour which nothing is improving, i restart the modem and i get a IP of 60.51. 1st half hour still no improvement but after 30mins the line suddenly came alive and back to normal.
im now getting a speedtest result of DL 700+/UL 300+.. well, its acceptable for a 1mb line.
