For the past few days i was noticing a slower speed on my DSL. At first LinkDotNet’s customer service department was trying to convince me that it was only because of the shared connection, and i would not get lower than 30Kbytes per second. I had almost made my mind to move to PTCL 
and said okay, good bye! While browsing through modem’s control panel, i eventually noticed the incorrect connection information! it was written 532/128 instead of 1051/285 (LDN values for 512kbps and 1mpbs), called them back, waited for 10 minutes to catch a representative, and got it resolved within next 5 minutes 
Moral of the story: Do not trust PTCL, LinkDotNet, or any other company. They would fool you up any time! Keep an eye on every thing you are paying for.
Hello,
I’ve got automatically my PTCL DSL Package doubled…
It was 512kbps before… last Sunday download speeds automatically doubled… I was wondering that what happened to it… then I logged in to router panel & noticed that dounlink & uplink are doubled…I was thinking that there may be some problem with my DSL connection, & it may be done mistakenly…
But yesterday I came to know that all of other PTCL customers also got their speed doubled… & it was the package upgrade by PTCL…
Moral:
Do Love with PTCL
