BSNL
Slow Download speed

Hi,

i am using bsnl broadband since last year but i am having problem with its slow downloading speed.

My connection plan is home unlimited 256 kbps but downloading speed is only maximum 30 kpbs.

i had a home 250 before that then i use to get something around 150 kbps downloading speed.

so does this means bsnl is limiting unlimited usage?

i took a speed test here are the results which is very poor
