PROBLEM IS SOLVED!!!!
What I actually did was changed my ptcl modem with 2700HG-B Gateway 2wire DSL modem and no more unplugged error pop up messages now. I think the problem lies within PTCL modem. You gotta accept that PTCL modem sucks hard. So, my recommendation to those who have this same issue, to replace your PTCL modem with any other DSL modem.
Thanks for sharing your views, ideas and bad experiences lol.
CHEERS!!!!

Nah! Mate, wateen isn't as promising as it was before. I had been using wateen for last 3 years but now recently get rid of it. The reason I unsubscribed is I wasn't able to stream online videos for like 2 months and When I ask them to fix this problem they always had this answer,"Sir, We have no issue on our side, it must be your machine or another problem on your side". So I did what I actually was suppose to do.
PTCL, SO FAR SO GOOD !
