DLM is finished, are there any SNR tweaker for SAGEMCOM..?

[snadge]

I think my DLM has finished, the sync is same as yesterday (15,300k / 7.1db (6.1db yesterday on same sync)) and WAN uptime is way beyond 24 hours indicating it did not re-sync last night, so i THINK it might be finished.

my friend who is also on SKY and has line capped at 13,200k / 7.1db has just used an app to tweak his SNR on his D-Link to 4.5db and low & behold it went up to 15,400k.!! I thought this would be impossible on a capped line...so instead of waiting for 10 days to go by before ringing SKY to ask for it to be un-capped Im tempted to try my Netgear GT and lower the SNR Margin

what is the score here? will it still go up even on a capped line? if so, if I get in uncapped will it go further? (is the cap even restricting the SNR tweaking?)


thanks

I am not 100% sure about 'capping' done by DLM but manually there is a range of speeds which it can be capped at so DLM may be the same. Generally1/2/3/4/7/8/9/10/16/18/20 Mb*. If you are syncing at 15Mb at the moment the cap is probably 16. It is usually better to give it 3 clear days of no movement before you assume that DLM has completed.


*This information was passed to me by a Sky employee some time ago, I think it is still current. If it isn't, someone will surely say.

after dlm left me sync'd at19995kbps, the cst lady that had been overseeing my migration kindly phoned to tell me what my sync was, that my max attainable was 21 mbps & that my profile had been set at 20 mbps.
so yeah, i guess caps do exist, but significant improvements made to a line after it's been set should be reported to sky & they'll change it.

thanks Tom & Gymno - I heard the 3 day thing too (if WAN uptime is more than 72 hours then its finished)

Anyway, I couldnt resist and had a bash, I copied the MAC address of the sagemcom into the Netgear GT, changed the paramaters from o2 to SKY and entered the generated login and it worked BUT when i lowered the SNR it stayed put!! - I seemed to get slightly better results on pingtest using the netgear BUT upload speed went down from 1100 to 950 , so ive plugged the sagemcom back in...

s'funny how my friends SNR lowers and increases his speed when he has never called to get his line un-capped (it was at 13,700k over 27db) - but he used the supplied D-Link with some software that allows you to lower SNR, so maybe works differently over MER as opposed to PPPoA (tweaking SNR on capped connections)

That would show it's not actually hard capped but it's syncing at the best speed it can at a 7dB setting (which is what it's meant to do). Lowering the target SNR would, in this case, increase the speed

[Isitme]

BUT when i lowered the SNR it stayed put!!

Did you resync or reboot it after you made the changes?

[snadge]

@ IWasNotTheEnemy - I see, I thought profiles were always capped ..?

@ Isitime - yeah I re-sync the router and SNR stayed put @ 7.1db , download speed EXACTLY same, upload speed was lower and pings were tiny bit better

thanks guys

It would be a hard cap if you lowered it to say 3SNR and it stayed at a set speed but if you lower it and it goes UP then it's just the SNR at 7 setting the speed

[snadge]

but if you lower it and it goes UP then it's just the SNR at 7 setting the speed

mmm lost me there, he lowered SNR - it re-syncs and says 4.5db in his D-Link and sync rate went up by 2,000k - if what you say is right then his SNR should still be saying 7.1db?

also, how does speed go up and SNR stay the same when you lower the SNR..? (which did not happen to him - his SNR reports 4.5db)

[IWasNotTheEnemy]

Not if he's changed it to connect at a lower SNR then it will connect at a faster speed if the line is not hard capped. If he lowered it and the speed stayed the same then it would show the line is limited to a set speed
