Inconsistent Fibre Speed & High Ping.

Hello! 

I'm wondering if any of you guys are experiencing this after upgrading to Starhub's fibre broadband.

I've been getting very inconsistent connection ever since I have upgraded to the 200mbps fibre broadband from my trusty ol' 50mbps non-fibre broadband. It's been running way below as advertised and my ping is much higher than my previous 50mbps plan (from 10ms to 30ms). 

So, my experience with Starhub's internet has gone worse ever since I upgraded to their fibre plan. 

Any views?
