VDSL Stats - Whats yours?

godskitchen

Hello all,

I thought it would be benificial for us to build a database of VDSL line stats and speeds we are obtaining.

I think it could help some people establish if their lines are of poor quality and try and get something done about it.

Its also a bit of fun if you are into that kind of thing.

For the sake of keeping things tidy I propose we could set out the data as follows. I will use a real site I look after as an example and will be adding more when I get time.

Approximate distance to Cabinet = 700 - 800 Meters
Connection to the Modem = 50cm Cat6 (single pair used) from line point of entry into building to NTU.

Using http://www.speedguide.net/dsl_speed_calc.php as a rough guide my line stats suggest I am 1484 Meters away from the cabinet......

I think there is something wrong with the line somewhere.

cork981, how can you tell cab has gone live?? i am tearing hair out as i have been told " cab has been enabled but it may not have been switched on yet!! this was a month ago. I am in ennis, did you have to reboot router? and how can you get the right port??

I assume you are in CORK!!

domeld, where are you??

All I have is very low pings ie 10ms, its even 1ms to enniskillen! speed stayed the same, ie 38mb and at 800m from cab. I am expecting near 50 so that speed test speedometer gets close to RED!!

SpaceTime

I must re-test mine later on.

Modem lost sync for a few minutes during the night and came back up with a higher SNR and higher attainables.

I was in the same position as you I only had INP enabled for the last few months which gave a very low ping but low attainables.

K&N will have to come out and swap my line to a new port.

Apparently they came out today and coudnt find the port and just left.

I've also noticed it takes a lot longer to sync now that vectoring is enabled.

No vectoring here yet. Hopefully soon.

I'm 400 to 500m from the cab, installed today, cabinet in place since February but only live since 30th July.

Speed Test over Wifi, should I be getting better download speed compared to upload speeds

ED E

Its not too unusual, transmitter in the laptop is a little less efficient.

foggy_lad

My poor upload speeds appear to have been sorted out by Vodafone,

This is a wireless test but shows the upload has increased from less than 12mbps to almost 19mbps:)

Vectoring has just been enabled a week later, Vodafone unable to select a higher profile as of yet - the lad on the phone reckoned that they're systems are updated on the first tuesday of every month (?)

There's a good chance you'll be unstable at 80, prequal will probably only allow 70 too.

Dcully

efibre installed a couple of weeks now, rock solid performance that im very happy with but people connected to other cabs in the town are getting 95mb dload,im about 100 m from our cab and nothing has changed.
Is there a set time per month for a prequal?
How do i find out if vectoring is enabled on our cab?

Stats i believe are very good?

eircom has been delivering flyers in the estate the last 2 weeks stating that 100mb is now available in the area, ring vodafone to try get my profile changed and they say eircom still have my line locked to 50/15. its mainly the upload i want more of, even when i had magnet on the same line i was synced at 50/20 and that was before vectoring with a snr of 6dB

You're on a 40Mb profile, so the rate adaption wont change it. If it was 50RA then you'd bounce around 42-44Mb.

Upstream could be struggling a little.
