Hi,

I've been using airtel broadband service for the past two and half years and I'm very happy. My plan is 384Kbps and I used to get download speeds ranging from a minimum of 44KB to 52KB per second.
For the past one month this has gone bad from 32 KB to 36KB max and I'm in the same plan.
I would like to know the following.
-> What should be the Ideal SNR/Attenuation/Downstream and Upstream values
-> Installing a Wireless router has any effect on bandwidth? But using my master PC wired (Connected through Ethernet cable to Netgear wireless router)
-> Where can I check the correct download/upload speeds other than speedtest.net?
-> I measure the download speeds when I download files from rapidshare/utorrent.

Kindly clarify these...I've called the customer care they asked to download Dr TCP and change the MTU value but doesn't seem to have any effect!!!

Best Regards,
Pradeep

SNR

6bB. or below = Bad and will experience no line synchronisation and frequent disconnections
7dB-10dB. = Fair but does not leave much room for variances in conditions.
11dB-20dB. = Good with little or no disconnection problems
20dB-28dB. = Excellent
29dB. or above = Outstanding

Line Attenuation

20bB. and below = Outstanding
20dB-30dB. = Excellent
30dB-40dB. = Very Good
40dB-50dB. = Good
50dB-60dB. = Poor and may experience connectivity issues
60dB. and above = Bad and will experience connectivity issues

Line attenuation also affects your speed.

75 dB+: Out of range for broadband
60-75 dB: max speed up to 512kbps
43-60dB: max speed up to 1Mbps
0-42dB: speed up to 2Mbps+

download speeds can be tested out by downloading files..
wifi router will not affect internet download speeds
