@debayan Welcome to Broadbandforum.in
No idea what is your problem.
What is pf.no? you mean IP like 59.92.60.215 ? This will always change,and is called DynamicIP (whenever you disconnect and connect again your Internet connection ).
What is your present tariff plan and speed ?
Did "they" change the telephone line connections ?
What is happy hours in BSNL ?
What is the modem you use ?
expected max speed in ideal conditions. for 128Kbps 16KB/sec
256Kbps 32KB/sec
512Kbps 64KB/sec
2 Mbps 250KB/sec
look i was using te broadband with my existing land line.as they were unable to give the pf connection(free phone line connection comes with BB).now as i was getting low speed they have swapped the connection means they have given me the connection through my pf line.now the speed during free hours comes lower than before.
i am using bsnl H500 plan
happy hours 0200-0800 download n upload is free during this time.i am getting around 230kBps speed during non-free hours but i am getting 20KBps during free hours. i am using
D-Link GLB-502T modem
