Hi having previously lived in Klang Valley I can say that Streamyx is crap there. I had to use proxy to be able to raid at 300-400ms. If not it be around 600ms. Now I live elsewhere and Streamyx is constant (ie no disruptions) and smooth (raid at 220ms without proxy) (same package).

I suggest before you change to Unifi check that your modem is in good condition (try buying or borrowing a new modem and test to see if it is the same speed). Also make sure nobody else is using the internet when you're raiding. Reformatting your pc might work as well.
