Are you from the Philippines?!?! If yes, then you need a lot of luck. Not that i know of any tools that could really stabilize internet connections from other countries but if you're from here, then you just have to try what works for you best. It would be trial and error because different ISPs works best in different places so you really have to try it for yourself. The problem here is that they implement the "lock-in" period. If you want to test their internet connection, you'll be locked for their terms for 1 year. And if you're not satisfied and wanted to get out, you'll have to pay the internet connection for the remaining month that you are locked in. So best ask what is the best ISPs at your place. You could ask computer shop owners for their feedback.
