I like to think of the SNR
as the idling/tickover speed of an engine. Too low it will stall, too high and it is wasting fuel.
So the target value is above 3 but below 6 and the default should be 6.
Downlink target SNR margin (dB) Downlink connection speed (kbps)
|18 (worst case)||3008|
|9 (TalkTalk's initial default)||4768|
|6 (BT's initial default)||5568|
You can see that (in the example) TT have a speed of 4768 as a default, but if the SNR value is set at 6 then the speed increases 5568.
So a speedboost may be attained by resetting the SNR.
MINE .... Line Quality
I like to think of SNR as a margin to prevent crosstalk on a line. If you have a lovely, smooth electrical signal with little interference then it can be set low. If OTHER ELECTRICAL DEVICES OR BAD CONNECTIONS ARE SCREAMING ALONGSIDE then it can't hear itself think. 😉
Don't get sucked in by comparing very old ADSL profiles with anything to do with VDSL.
The frequencies used are different for a start.
The speed will increase with a lower SNR but at the expense of stability past a certain point.
You haven't even mentioned LINE ATTENUATION !
High 50s would seem about par in you area, plus or minus depending on distance from the cabinet, you seem to fall on the minus side. BT, Sky etc. give their products different names, but they do charge more depending on speeds available I can assure you.
It seems to me that it is what it is. And the readings from the Openreach meter which you posted yourself are the most accurate you can expect.
Honestly, I don't see how you are being "mugged off?" Maybe you are getting too hung up on numbers? Is there anything with your broadband service which isn't providing what you want? My speeds are only a bit faster than yours and everything works just fine including multiple users, 4K streaming, teenage son gaming etc.
well most people are after more speed its always been that way 9600k,14.4k,28.8k,33.6,56k modems etc always onwards and upwards. I`m sure someone said the same thing when the first 56k modem came out.
I bet the people of South Korea would not put up with our FTTC speeds what are they on about 1Gb speed or something. With everyone in a normal household on a mobile phone which is hooked onto the net along with there pc/tablet not to mention there smart TVs and xbox or PS3/4 and soon to be PS5. I`ve got to be honest 40+ is no good anymore yes 5 years ago but now/next year..........history proves it. No is the answer
Not speed for speed's sake, just enough for what you need. Not what they would like to sell you yee-ha!
But I agree longer term of course, Openreach and other providers are belatedly improving the infrastructure. What hacks me off is that it is almost entirely subsidised by Government spending i.e us, but we are expected to pay premium prices.
I would bet a good percentage would not want to lose their landline at the moment, as TT's FTTP service doesn't offer VOIP either.
I really don't want another hole in a wall and like many others, do not have any spare sockets in the right place for the ONT power supply and router.
The higher speeds then bring up other issues, which I have already encountered at my second home, device WiFi capabilities are below the incoming speed so customers will start to complain despite the actual problem being with their own equipment.
Those of us of a certain age have all been there, much more recently in some cases. You still haven't answered why 100 gigazigawigga or whatever the top speed the marketeers are trying to sell will represent an improvement for most users, or how people can or should be expected to pay a substantial premium for the privilege? Decent broadband for all?
