  • How to use SNR tweaking for a faster or more stable connection

I just tried using Kareem's command on my X1000 and to my surprise it worked!
My max rate jumped from 13 mbps to 18.7, I lowered my SNR from 15 to 9 so I'll be monitoring my connection in the next few days, is 9db considered very low? will it affect gaming etc?
Are you with Ogero?
Because on IDM, whatever is the SNR margin, the rate is locked.. I lowered mine from 14 to 9 and the rate didn't change at all
Sodetel, but now that you've mentioned it on speedtest.net I'm always getting lower speeds, for example I used to get 11mbps now 14 mbps, I'm planning on moving to ogero next month anyways

Seems like the target SNR set by Sodetel is 15dB which is astronomically high, as in too safe.
I'm also with Sodetel and I once requested the SNR to be lower than 15dB they kept saying that it's not them who set it. I can't be a hundred percent sure it's them but seeing your feedback that should be it.

Of course after I discovered I could tweak the SNR by myself, I couldn't care less.

Fresh results:

Pre-tweak - 3.2Mbps sync

87.5% throughput

Post-tweak - 7.2Mbps sync

81.9% throughput

204% higher throughput
225% higher sync rate
0% errors
Anyone got a guide on how to tweak TP-link modems (VR-400)

I have the tp-link vr900 and I don't think SNR tweaking can be done on these models :(
If someone knows a way however, it would be highly appreciated.
Can anyone give a step-by-step guide as to how to tweak the SNR for the standard Technicolor DSL modems that ogero gives u?
SNR tweaking does not work with IDM /GDS. The SNR changes but the speed is locked at whatever they chose.
No way to tweak the thomson TG585 V8 although it's very easy on the V7, the V8 adslctl command was removed .

adsl configure --snr xx

To understand more the value of XX, check the link below :

basically you wanna reduce the SNR Margin ( not SNR ) in steps of 3dB. reduce and test stability. mine won't go below6 dB

I tried Kareem's Tutorial but with no luck, The error is that Invalid parameter.

My guess is that I haven't entered through configuration terminal since the command

>adsl snr
shows
------the table SNR per tones(carriers) of the interface ADSL2+-----

any tutorial for dummies?

DLINK DSL-2750U

The C1 revision of your modem has a Broadcom chipset, however the U1 has a Realtek one. Now if you have a Broadcom chipset and it didn't work, it might be that the manufacturer removed the feature.

How can we do it on the v7? I've been trying a lot, and it can't seem to work.

There is a custom Firmware for the V7. Check online but I am not responsible for any damage.

Meanwhile :

I noticed today that my DSLAM's target SNR margin was set to 8dB (I am on Sodetel DSP, but I'm not sure who controls this). It was set to 10dB until yesterday. It seems that they're able to put more load on the network so they decreased the SNRM for extra speed.

Usually it should be the other way around when they have high load since higher SNRM improves stability unless i'm mistaken.

Not sure we understood each other correctly.

But what I'm speculating here, rephrased:

Sodetel put the target SNRM to 10dB initially. They tested it and found that their network can handle more load and still be stable, so they lowered the SNRM to 8dB to give more speed. Now the load is higher than before, but still not high enough to cause stability problems from their side.
@Adnan, what about Thomson modem tg 585 v7
@Mylo89 mohamadk97 has the same modem. It has a broadcom chipset so in theory the tweak should work. But unfortunately it didn't for him. Can you try the broadcom method provided by Kareem to confirm ?

If it fails, you can try flashing a custom firmware as Kareem suggests.
