I've been getting moderate to severe packet loss on my BSNL broadband connection ? Anyone else experiencing similar issues ?

Here's a representative ping dump from google.co.in :

Is it hampering the speed, you ar getting???

kirankumargb

check if that is only for that site or all sites... best is check you speed at speedtest.net & post it here with your plan details and SNR ratio too

rsen

Yes, it's for all sites; Speedtest.net works at times, fails at other times (it won't even connect to the latency or download test at times).

Lots of packet loss = slow/interrupted browsing.

Sometimes when it get really bad I try to reconnect to bsnl but I get the error message "the remote server is not responding".

Home1000.
How do I check my SNR ratio ?

kirankumargb

goto 192.168.1.1 type username & password as "admin" without quotes. there in the default page will get it... if not check page which is something as summery etc..

you will get full detail on ADSL page

rsen

huawei MT841 modem
got it from basic->system information
SNR Up/Down: 18.6 dB/28.0 dB
Attenuation Up/Down: 3.5 dB /22.5 dB

kirankumargb

oh dear thats really bad... thats why you are having so much of problem.... i think you should complaint to BSNL to check your line... there is certainly major problem in line... is there any disturbance you here when you pick up the phone...?

rsen

What kind of SNR/attentuation is normal ?
I'm not really getting any disturbance on my phone line when I pick it up.
The problem started around 4 hours ago, it's usually never like this.

essbebe

Modem AX MT841.
@rsen
please report any further development.
Sudden problem means, some electrical/electronic/wireless/pick up in your location.

Change Mod to GDMT and
see under summary any improvement in SNR/Attn

Will try some speed optimisers later.
TTL value shown is high..

rsen

Should I change it here ?

What should TTL values ideally be ?

I got TCPOptimizer from speedguide.net.


speedtest.net mumbai server seems normal I think

P.S. sorry for screwing up alighnment with the large image.

essbebe

Yes select gdmt /t413/glite or multimode.
Bitswap enabled.
adsl2+ for high speed connections.

Speed etc seems normal.
using the optimiser try recommended values.
MTU/MSS/TTL etc are interrelated.

rsen

Alright thanks a lot, I changed all those

What connection speed should I choose on the slider ?
I'm currently using Home1000 and the download speed is typically somewhere between 1-1.5Mbps.

rupu1983

But I don't have such problem

essbebe

Values will change according to the speed you selected 1 Mbps will be Ok.
Wait for a day and report
packet loss. try some other site. also.
do tracert Google.

opendns 208.67.220.220 and 208.67.222.222
recommended.

rsen

How do I change the DNS servers ?

I'm still getting some packet loss (it's quite random, with a few minutes with no packet loss 0-2%, and then a few minutes with heavier packet loss 4-6%)

then finally check it by ipconfig/all in command prompt

just kick BSNL A** for this changing values,settings etc wont help ur connection is leaking badly, and connection speed have nothing to do with ping reply time.

Thanks a million rupu.

Which dns server is best for online games and occasional streaming audio ?

Yeah BSNL definitely sucks but most broadband providers in India are terrible so there isn't really much to choose from, especially in Kolkata.

I would say internet settings do affect things since I remember tweaking a few settings made streaming audio and some online gaming a lot better.
e.g. changing TcpAckFrequency to 1 and TCPNoDelay to 1 [basically send ack for every tcp message and deactivating the Nagle algorithm to improve your ping]

Hi RSen,

did changing the DNS server solve your problem ?

I am in Bangalore and facing the similar problem since I took BSNL broadband.
I changed the DNS but of no help.

I have Huwai 3002G4 modem.
I am still have 3-10% packet loss at any given time duration. (with or without wire).
I have MS-Vista(home edition) on my HP laptop.
I searched a lot on net, complained with BSNL and from last 10 days no action from BSNL
Any help will be appreciated.

I am also looking for other service provider in my area.
