Thread: drastick speed reduce in home 500 !

i am geting an average speed of 230 kBps in torrents and upto 260kBps in idm !
but from yesterday i am getting speed of max 25 kBps........
even the webpages are loading very slowly !
here is some info about connection
modem ztezxdsl531 b







any possible solutions guys ?

my connection is like this
main line into splites than one line in my modem in firstfloor and other one in the phone on ground floor !

now take a look at evening speed...................


unbeliveable line rate(anyone jealous of me) is anyone else also getting such a wonderful servise



scanned completely with avg 8.5 updated version no virus.......
no one can belive this f**king bsnl connection

its 2010 man and these morons of bsnl still giving us connection of dialup age

any more info ?
plz let me know thanks..................................

Attenuation values not good. Get your line checked.

line checked by the line man he says the line is working perfectly ????

now wat should i do ????

@meetdilip
Attenuation don't have much effect, mine is worse than him & I'm still getting 165 kBps in uTorrent & 230 kBps in IDM.

@arpit
Your stats page shows wrong values in Rate, if your plan is Home 500 it must show 2048, just tell BSNL person to change your port, your problem will get solved.
& Try different server for speedtest, like chennai you will surely get good result.
I tried it Mumbai is giving bul***t result & Chennai is fine.

For BB 500 the port speed should be at lest 2048Kbps but not lower then it. Higher then 2048Kbps is good. There is no need to chenging his DSLAM port.

I had a similar problem, I just told them to change my port & my problem got solved.

so wat to do ! still not getting speed !

First change or set your ADSL mode to G.DMT and uncheak all other options.

your line condition is good and your DSLAM port speed is also correct for your BB 500 Plan. There is no problem from your Exchange side. Now only remain two side from where this type of problem can be arise. first from your Computer side. Cheak your LAN Link-ACT LED is it continue blinking when you dont use your computer for browsing and downloading from net. Before cheaking it remember to log in to your ISP. If all is OK from your computer side then only remain the side of your account policy. This is from your BSNL side. First cheak what is the maxium speed you getting now. Is it 25 to 32KBps and never increase that level. If that is then you and others user of your DSLAM network getting same speed like you are getting now. Because some time BSNL need to reduce the speed of the network for saving the bandwidth. It will automatically set to correct level after 15 days to 20 days. But it's depaind. Only you can do is that complain a doc to your local exchange or talk to your DE in your exchange.
When you testing the current downlod speed use utorrent with private torrent site and bridge mode. IDM dose not shows the correct download speed allwase shows greater speed then the actual speed.
One good private torrent site is iLoveTorrents.com Where the Love of Torrents is Born
Sign up there and cheak it

@Sumit020
When need to change the port. If the signal of the DSL not getting from the CPE side. If there is very low SNR value. If the port speed allwase fluctuating. If the user getting the error 678. If there is frequently disconnection or out of sync from the DSL signal but line condition are good.

sorry what is lan link-act led ?
i have four leds in my modem power,dsl,internet,wlan.....
what is the difference if i select all the option instead of only g.dmt ?
i am member of top notch private trakers such as scc,tl,waffels etc.....
few days back i am getting average speed of above 225kBps in single torrent also
but now i am getting only arround 90 to 130 and its only for few seconds and its reduces back to 20 and then again to 120 !!!!
just like downloading from rapidshare free account.....
checked in what.cd max speed 90 kBps at the time of posting
(enough seeders so thats not the point of slow speed)

responce time is also very slow 15 sec for google and even minutes for tl ,iptorrents etc using open dns !
disconnecting now and then !
is there any problem in the modem or in the port in bsnl exchange ?

speed after selecting g.dmt
though the attenuation rate falls to 40 db.............



my bro in usa he is with comcast cable he always get a and i with bsnl


hey guys what about an irc channel of ibbforum live help is really handy ?

you can fiend the link-act led behind your computer case in your LAN port where you connect the cable from your router.

If you select all option then your ADSL CPE automaticaly select the high bitrate mode. Which is ADSL2+ but remember that only when it will select this mode automatically if there is higher bitrate mode available and if any perticular mod is set to default in DSLAM then ADSL CPE will set that mode automatically.
In your case you dont feel any deference because your port speed is good in ADSL2+ mode. Some users have problem with ADSL2+ because there port speed not set correct in DSLAM of ADSL2+ mode. Some time they get below 2048Kbps port speed in ADSL2+ mode. So they need to cheak only the option of G.DMT
G.DMT support upto 8Mbps Download and 1Mbps Upload
ADSL support upto 12Mbps Download and 12Mbps upload
ADSL2+ Support upto 24Mbps Download and 1Mbps upload

for getting upto 2Mbps and upto 8Mbps set mode to G.DMT
for getting upto 16Mbps set mode to ADSL
for getting upto 24Mbps set mode to ADSL2+

You can set mode to ADSL or ADSL2+ for the plan upto 2Mbps and for 8Mbps but the SNR value will be change.

Problem from your Exchange. Your Exchange dont get the good Speed in their leased line so it cant handel the traffic.

@arpit60

ur line has fault as the snr (Singal to Noise ratio) margin that is 9db for downstream is very low..BSNL prescribes a snr of min. 14db..and ideal snr will be 20+db. also check the splitter and other lose ends.

SNR or Signal to Noise Ratio:
Describes the ratio of usable data-signals on your line. You can associate the "signal" with the data traveling across your ADSL-line and the "noise" as the unwanted interference affecting the signal. The higher the number the better for this measurement. In some instances interleaving can help raise the noise margin to an acceptable level.

6dB or below is bad and will experience no synch or intermittent synch problems
7dB-10dB is fair but does not leave much room for variances in conditions
11dB-20dB is good with little or no synch problems
20dB-28dB is excellent
29dB or above is outstanding

If your SNR is below 12dB you are pretty much screwed and will not get a consistent level of ADSL-service.

Attenuation:
Is the reduction in signal strength on your phone line. In ADSL this may be reported as "loop loss" and is the natural deterioration of the ADSL signal over distance from the exchange. Attenuation is normally directly linked to the length of your line. Copper is traditionally used in the local loop and the higher gauge of copper will give the best signal, however some lines may have some aluminium or aluminium joints on the line which will increase resistance... as will oxidisation of joints. The lower the dB the better for this measurement.

20dB and below is outstanding
20dB-30dB is excellent
30dB-40dB is very good
40dB-50dB is good
50dB-60dB is poor and may experience connectivity issues
60dB or above is bad and will experience connectivity issues

SNR will change to correct If he select the G.DMT mode but I dont think it will change his download speed because the value SNR dont effect the DL speed.

i think he stays too far from the xchange since for a home500 plan his line is synced for 6740kbps, but ideally for Home500 the sync speed for downstream is 2048kbps.. While having a high sync speed will not necessarily translate into high speed. As the distance increase the attenuation increase and snr decreases. To fix this issue you will have to visit the exchange or talk to other indoor staff in bsnl exchange

From ur modem values in the first post i can see a high no. of HEC errors . HEC is header error check-sum. You are getting errors in the cell headers. Your speed is set too fast for your line conditions. If your speed was reduced to 2048kbps down and 512kbps up your line would see fewer errors. There could be a physical line trouble that is causing the errors. it is time u paid a visit to the exchange

by the way from which place r u arpit60??

i am from gujarat aprox distance from exchange is 7 km i cam vist exchange tomorrow what should i say to them and what homework i should do before meeting someone i dont want to be a noob at the exchange !

• You are not getting the advertised speed of 2mbps ..even for local servers..leave alone international servers
• the snr is too low
• the attenuation is too high
• high degree of HEC (header error checksum) errors
• despite syncing the line for 6740kbps you cannot even receive 2048kbps / 2mbps speed
  

u r from which district in gujarat??

i am in bharuch district aproxx 1 hour from baroda and surat !
should i talk to sectional divitional engineer and how they can solve my problems ?

yes..talk to DE or SDE.. and contact the oficer of DGM rank if u dont get a positive response from exchange or problem is not resolved.

here is a link

Welcome to Bharuch Telecom

once again i am getting the speed of above 225 kbps do i still need to visit exchange ?
my stats still poor
SNR Margin (dB): 8.7 25.0
Attenuation (dB): 40.0 22.0

arpit60 read my previous post about your quaries at post number 262002 and 262015 last one. You can understand why you were getting this speed. I allrady mention there and that was the root of your problem. You only need to be patience.
