@madhouse12 actually i was updating the firmware of my router last week at that time i saw the speed and it was doubled...and secondly I'm using ptcl broadband since its launch..originally I started frm 256 kbps then the package was upgraded to 512 kbps, and as you all know 512 kpbs was upgraded to 1mbps last year...n now i presume it is updated to 2 mbps or whatever..I remember when first i got dsl connection, Ptcl was giving volume based packages (like 2GB a month, and unlimited use for first 3 months) at that time my 256Kbps connection was configured at 2 mbps...and I was amazed by the ptcl speed and performance and after first 3 months my connection was re-configured at original speed of 256 kpbs
anyways I'm enjoying it much these days because my internet use is quite high as of average ptcl user because of my work and stuff!! Thankfully I never got any issues with PTCL DSL..its been more than 3 years now...
I also heard that before upgrading the packages to all users ptcl upgrades packages of few customers on random and use basis to test feasibility (it might not be true), if it is the case then i believe the upgrade will be given to all users sooner or later...
