Start from last week, my 4MB speed always slowdown on night time around 9pm to 12am, the speed test result i get is around between 500kbps to 600kbps only, call 100 also can't solve my problem. The speed will back to normal after 12am, around 4200kbps. I can't watch pps, play online game or even hard to open webpage when the speed slowdown.....how come TMNET can limit our speed on night time?? we paid for it, this is not right for them to slowdown our speed!
