Thread: Speed Problem

guys! i was havin frequent disconnection last week..bsnl mechanics came and changed pair of connection...then everything was almost fine...

i have also changed my plan from 500 combo to 600 combo last week..

but from last two days m getting download @ 10-20kbps...



SNR & Attenuation


upstream super frames errors was not this much before

Your attenuation rates are pretty low.
Get it checked from the JTO.

Also, BSNL is having problems since 3-4 days now.

attenuation below 20dB are said to be great...

so any other suggestions please?

factory reset ur modem

I'm also getting serious drop in speeds since a week! Speeds have dropped down to 5-10kbps while they were something like 65-80kbps just a week ago. cant even open a damn site even this forum wont open properly and pings have risen to 1000-2000 when they were 150-200 earlier

Whats wrong im totally fed up and i need to know when will all these repairs be finished ???

@akrvd
What is your tariff plan? If 8Mbps plan is not used, change Mod mode to GDMT and repost SNR etc.

@shivendra
Post screenshot JPG of Statisitics adsl page showingSNR/ATTN
or Device info page. Mention modem model/make/number.

How do i upload screen of SNR/ATTN.

I can only tell you my model: UTstarcom WA3002-g1

we need to disable both adsl2+ n adsl2 or only adsl2+??

details about adsl

ADSL stands for Asymmetric Digital Subscriber Line service. It is called asymmetric because the download and upload speeds are not symmetrical (download is faster than upload).

ADSL2

ADSL2 (ITU G.992.3 and G.992.4) adds new features and functionality targeted at improving performance and interoperability and adds support for new applications and services. Among the changes are improvements in ADSL's data rate, an increase in the distance ADSL can reach from the local telephone exchange, dynamic data rate adaptation, better resistance to noise, diagnostics, and a stand-by mode to save power. ADSL2 also reduces the initialisation time from more than 10 seconds (as is required for ADSL) to less than 3 seconds. ADSL2 has the same signal footprint as ADSL.

ADSL2+

ADSL2+ (ITU G.992.5) doubles the bandwidth used for downstream data transmission, effectively doubling the maximum downstream data rates, and achieving rates of 20 Mbps on telephone lines as long at 5,000 feet. ADSL2+ solutions will interoperate with ADSL and ADSL2, as well as with ADSL2+. ADSL2+ will include all the feature and performance benefits of ADSL2 while maintaining the capability to interoperate with legacy ADSL equipment.

this means we need to disable both..as G.dmt is ITU G.992.1...right?

By this time you could have disabled one by one and selected the best settings!!!!
I have already mentioned Google search for details about theory questions !!!

i changed it but now my snr is very low...

m using home combo 600

try again in adsl2 + and report any improvement.
