Just checked my stats:
Downstream Attenuation 22.2 dB
Cable loss 13.81 dB/km (default=13.81) -not sure what to put in
Approximate Distance 1608 meters
ADSL Max Speed 8000 kbps
ADSL2+ Max Speed 19758 kbps
VDSL2 Max Speed 20771 kbps

So when vectoring comes in I should get 20Mbs?

Best to login to the eFibre modem/router go to;
System Monitor -> xDSL Statistics
It's the "Attainable Net Data Rate" is what you might be able to use as a guideline for post-vectoring...fingers crossed!

My downstream attenuation is 35dB with Sky but with Vodafone I specifically remember it being 20.4dB, I think I even created a thread on it.

Anyway, I can't get fibre yet because I'm with Sky and they don't offer it yet, even though when I check my LandLine + Address they both come up as Fibre enabled.

That might be correct from this online tool which I'm guessing your basing your info from, but your using the 'default' cable loss.
Now lets say Eircom have used cheap/crappy cable in the past 10~ years to save money and the cable loss instead of being 13.81 dB/km is now around 20~22 dB/km. Using that cable loss figure will show me the correct distance. Now unless Eircom have a 1km of a test/backup role of copper in a cab somewhere or now run their cables across fields my distance calc is correct

Interested to see how did you got 34.1dB from the stats I posted, can't work that out myself

i got it from the info you posted!

the 34.1 was a typo

He's with Vodafone. Looking at the screenshot of the configuration page on this thread, I don't see "Total Attenuation" anywhere.

Yes exactly - I am with VF and their DSL status page doesnt show the rate.

Ah ok - Can you find out the modem make/model? Maybe its hidden in there somewhere which we could check by finding the manual

Just got it installed this morning, happy enough but do ye think I could get any more out of it? Is there any chance of getting eircom to up me to 70mb?

Wait for vectoring to be enabled in the first half of next year, you should get up to 70 and if not more when Eircom move up to 100meg

Ah jaysus, how much do you want? I'm getting between 44 and 46 and I'm delighted with that. A few long months with sky bb would make you appreciate decent reliable bb.

Mine is being limited to 50MBps. Am i right in thinking it should be able to handle 70/20? Eircom won't even listen to me...

It should be able to handle 70/20 but only once 'vectoring' is rolled out and enabled which will hopefully be in Q1 next year. Until then you will have to do with 50/10...because that is super slow

My line stats are good and i'm close to the cabinet, i still think eircom has put me on the 50MB profile when i could handle more.

I've been paying €50 a month for the last year for 1MB bb which kept dropping, i just want to get all i paid for now since my line can handle it.

briany · 12-12-2013 8:11pm

Pulling down really nice speeds on the laptop's wireless connection. Consistently getting close to the 70mbps limit, particularly in the evenings. Ping could be a bit better but that seems to fluctuate anywhere between 15 and 60.

16.1 dB attenuation says your line length is around 1600+M be thankful you get the speed you do others with attenuation like that arnt as lucky

your getting more then yu should be

The box is across the road, about 200 m away. No idea why Eircom ran the line for 1.6km, bit of a waste of copper.

across the road it may be, but from sound of it cables dont run to that one

just like my closest is 600m away yet im connected to one 1000m away as thats the direction my lines run

Blah blah attenuation per km of copper, blah blah maths, blah blah distance.

There is a site for calculating it but according to that i should be on much lower speeds plus my net max speed should be way lower.

Of more interest is my signal to noise ratio, mine is very high.

It's no longer just copper now though.....

I'm about 190m from my cabinet as the crow flies.

So by that logic, 19.0dB Attenuation - the copper goes 1.9KM around the place before getting to my house?

Not my logic. Site is here http://www.speedguide.net/dsl_speed_calc.php

19dB shows 1.4km according to that site. I think SNR margin is more important. Plus your attainable data rate is a lot lower than what my line is capable of, that's why i should be able to get 20/70. Technically you could get 15/50.
