I've used 1mbps, 2mbps and 4mbps before. 2mbps speed in kilobytes is around 250kbps+ sometimes with IDM it shoots to 270kbps+ but will always be stable around 250+ what I did when I was sharing line, I'd limit my download speed per download about 75kbps so that other users in my house can surf internet without lag. Btw the pricing if I'm not mistaken

Hmm I doubt it will be of much help, although the cap is raised, your line can only attain to what it can achieve. They usually only increase it if you're speedtest in speedtest.tm.net.my below 80% of your package which is 3.2 that you're getting, like 2.9 or 2.7.
