3.4mbps to where? Speedtest.net? Maximum download speed from any website? Torrents? Modem sync rate? (Hint: the last one is the only one that matters/is regulated).

Your SNR is considered "good" by international standards, as in "Good with little or no disconnection problems".
Your attenuation is a little on the high side and would be considered "poor", as in "Poor and may experience connectivity issues".

The only way to change the latter one, however, is to either replace the cable or move closer to the exchange (or hope like hell that BSNL starts cabinetizing it's DSLAMs and shoving some shiny new fibre in the back of them so you're never more than a few hundred meters from one and your line will be capable of 16+mbit/s without breaking a sweat).

3.4mbps is as per Speedtest.net.

Speedtest is only somewhat useful as a measuring tool. If the line sync rate on your modem page is close to (or above) 4096kbps then you're fine and BSNL is complying with the regulations.

I stay very close to the BSNL exchange, only about 3 streets away but still get a max of 3.2 to 3.4 Mbps
I used to get the same speed even when i was about 2-3 kms away from the nearest BSNL exchange. The main issue is with BSNL setting the max transfer limit of 3999 Kbps of DL & 493 of UL on 4 Mbps connections, so we get only about 3.2 to 3.4 Mbps even if we have a latency of around 100 & can the speeds cab go down to even 2.5 Mbps or less if the latency increases to 200-300+

Most other providers don't limit the speeds on this level as per my knowledge & hence better speeds. Below is my SNR ratio, please comment:

You're a lot closer to the DSLAM than you think. Your line appears to be connected to a local cabinet containing shiny new ADSL2+ capable equipment, and within maybe 200m or so, and your line stats are very good, perhaps even enviable, even by international standards!

BSNL sets these limitations on your line because that's your plan. They *should* oversubscribe you a little but they don't, and in your case, they are more than meeting the regulations (whether the same is true for the OP I can't say without seeing the rest of his stats, but it is probably a vastly different story).

As mentioned, speedtest.net is only so useful at determining what your line can do - my download speeds on a torrent or HTTP transfers can sometimes be vastly different from what I'll get according to speedtest.net, and my pingtimes to the Mumbai server are usually in the vicinity of 10ms (or 6ms in command prompt).

So why do you only get 3.4mbit/s? Could be the distance. Could be a congested backbone. Could be congested interconnecting links. I wonder: what do you get to the new Bangalore speedtest.net server?

@mgcarley ...3.2 to 3.4 Mbps is the best i can get but it can go down really bad, not only by speedtests but even as tested on actual downloads from reliable servers.

Here are my results as tested today:

Bangalore(Airtel):


Hyderabad(Airtel):




Chennai (Vodafone):


Mumbai (Vodafone):


Same with Numion: http://www.numion.com/YourSpeed3/ShowMeasurement.php?ID=79,680,074

All this with the following stats:


Pingtest results:
http://www.pingtest.net

I'm on Google DNS as of now, have tried Open & even BSNL's DNS before but google was the most reliable

I tried everything with BSNL engineers - changing the cabling(that's what they first do whenever i book a slow connection ticket), checking at exchange, trying another set of equipment(known good according to BSNL): different modem, router, computers etc but the scene hasn't changed much. I somehow have started to believe that atleast the engineers did the best they could have & this is how BSNL connections work in my locality !

My average speed would however be around 2.5 Mbps going up to a max of 3.4 Mbps sometimes & dropping down to sub 1 Mbps levels at times
I'm sticking to BSNL because there are no other wired providers in my locality, Any suggestions to improve my speeds ?

I think your line is absolutely not the problem here, I think it's BSNL's backend/interconnecting links/upstream/etc - this has been discussed in some other threads such as https://broadbandforum.co/bsnl-broadband/76312-bsnl-broadband-routing-issue-high/ (check page 3 - there are live updates of BSNL's gateway performance as seen from Mumbai)

These are the IP addresses for all of the speedtest.net servers in India: maybe you could try a traceroute to the following IPs:

182.19.95.36 - Mumbai (Vodafone AS55410)
182.19.95.104 - Delhi (Vodafone AS55410)

202.148.202.180 - Chennai (Aircel/Dishnet AS10201)
223.224.43.250 - Chennai (Airtel AS9498)
223.224.50.242 - Hyderabad (Airtel AS9498)

Your cabling is fine. The exchange is fine. The Modem is fine. The DSLAM is fine. There is NOTHING you can do as a customer - BSNL's backbone is working pretty much at capacity, so unless/until they upgrade that you're going to experience crap speeds.

Try a traceroute to Google DNS as well. If 8.8.8.8 is outside of India according to your ISP, then your performance on some sites will be rubbish.

As you can see, nothing wrong with the connection on your side - it's where it all hands over to VSNL that the pings spike and the speeds drop.

Oddly, traffic going in the other direction is a bit better - excepting 117.192.160.1 I can ping all those other IPs in 65ms or less, but, my trace to that IP takes a different route (through Chennai) where the pings do spike quite significantly.

Please note i always get better speeds/latency to Vodafone servers. Other servers like Airtel have even worse speeds/latency. Posting them here:

Crikey. 250+ms to a domestic server is *good*? I feel for you, man.

Here this range 218.100.48.x is NIXI and it appears to be saturated links here too.

@mgcarley
Sorry to bump into this old thread again but i can't take these bad speeds anymore. I've tried all possible options as suggested by BSNL but i', still *not* getting speeds in excess of 2 Mbps(SNR has not changed). I even upgraded my plan from ULD1350 to ULD1700 this month(both are 4mbps but BSNL CC Rep asked me to try this as the last option because the "Port" etc at the exchange gets refreshed when tariff plan is changed - does not make much sense but i tried it either ways because nothing else was left) ... It took a full month to get this done, because BSNL has decided to go back to 'Stone Age' with their policies, they no longer take 'Plan change' request on the BSNL Website or even on phone, we have to go to the local exchange & give a signed letter / Application to change our Tariff Plan :cursing:

Here's the best speed i get now:



& my connection status (SNR etc):



Please help me with the correct escalation path at TRAI or any other authority, i've tried everything else at BSNL & nothing works, i can't even change to another provider because BSNL is the only wired provider in my locality

Forgot to mention that even a simple Youtube at 480p or even 360p buffers at most times....also forgot to mention that my SNR again increased further after BSNL worked on this issue again but only marginally - but this is still the best i've seen so far
