Thread: Data-One Problem

Hi frnds

I have data-one broadband - Home-unlimited plan. I have been facing problem with connectivity. It comes and goes. BSNL says that they have done whatever they could and find no problem. They claim it is problem with my modem (Sterlite, Smart AX MT 882) and must change it. I want feedback if what they say is correct. How to test a modem and whether a modem can get spoiled and if yes then what could be the reasons. My modem remains on for at least 12-14 hrs daily.
Would appreciate your help.

Thanks

Post your SNR and attenuation values. You may check your modem at your friend and find out. Borrow your friend's modem and try.

Book mark this link.

The values are:

UPSTREAM
SNR=31dB
ATT=10dB

DOWNSTREAM
SNR=12.5dB
ATT=22dB

i doubt
generally downstream would be better than Upstream
compare results from other people. and see this from me

before any attempt to change Modem, better try change the adopter
if that is noisy, it might give erratic results, perhaps.
also check whether the INPUT is AC, then the adopter would just have a transformer.

Hi
I did'nt understand your doubt... whether my figures are correct or wrong ? I checked again today and figures UPSTREAM & DOWNSTREAN are same. Please clarify... Alaso whether these figures indicate some defect ?
Thanks

That depends on the condition of the Cable and Server load(BSNL).

just to make sure , are all your telephones connected after the ADSL splitter?

Interesting problem:
Huawei AXMT882 Adsl modem.
If Mod mode is Auto or ADSL2+ uncheck.
select GDMT T413 or G lite and check.
You may loose Internet connection also.if only one is selected.
Disable Annex M.
( if available )
then recheck D/L/U/L
feedback please.

Your PROBLEM from Post No 1

I have data-one broadband - Home-unlimited plan. I have been facing problem with connectivity

What is the present condition now ?
Home 750U/l speed max 20 to 32 KB/sec
or 160Kbps to 256 Kbps

Pardon my ignorance..can youexplain the difference between KB/s and kb/s
I think max.speed for my plan is 256 kb/s.

Thanks

Kb and KB difference is bits and Bytes.

If the speed is 256Kbps means divided by 8 =32KB/sec
so in a minute 60 x32 = 1920 KB can be downloaded.
Usually you get a D/L speed of 10KB/sec to 25KB/Sec
1024KB= 1 MB 1024 MB =
