WBC - successful connections

[Rik]

Interesting, Steve. 

[PuncH]

Hopefully I'm not tempting fate by posting on here  

Moved on to ADSL2+ Friday 11th/Saturday 12th June.

I'm currently synced at 19690 with a line profile of 15000 and a throughput of 11500-15000 which I'm pretty happy with. Noise margin has gone up a bit from the initial 6.1db to 8.9db.

Netgear DG834G V4 firmware version 5.01.09

EAFOX Exhange, Ipswich.

Linestats:

ADSL Link                Downstream   Upstream
Connection Speed    19690 kbps    1232 kbps
Line Attenuation      16.0 db         6.8 db
Noise Margin           8.9 db          5.4 db

Good luck!

Hello all,

I appear to have been successfully migrated to WBC sometime around 10:00 on
15th June.

Netgear DG834 v4 firmware V5.01.14
Copper path is 1200 metres from Newtownards exchange.

Not terribly impressive line stats compared to what the online estimators were
predicting:

Connection Speed     7785 kbps     888 kbps
Line Attenuation                28.5 db    12.9 db
Noise Margin                11.9 db    10.6 db

Prior to the migration:

Connection Speed        5856 kbps       448 kbps
Line Attenuation             26.0 db         12.5 db
Noise Margin                   12.1 db         23.0 db

Ta,

El Bunto

[El Bunto]

Replying to myself, speedtest.net shows that my throughput has fallen from 5.20 to 3.34 mbps.

After

Bah!  Well at least I still get the extra download allowance...

Wilco, it is erroring-out as busy right now but I'll give it another go shortly. 

Richard's results are amazing; my traffic results are about the same as usual:

That's quite a high ping time considering you're on WBC. This is what I get on a standard ADSL line (no interleaving):

Exchange congestion maybe?

[Rik]

That would be my first thought, Tom, followed by a node issue.

[El Bunto]

That would be my first thought, Tom, followed by a node issue.

As far as I recall, Newtownards connects via the Glasgow node.  I suppose there is a delay because the packets have to get the ferry across the Irish Sea... 

Pings have always been very poor even prior to WBC though as a non-gamer it didn't really cause me any issues.  But Richard's results were an eye-opener!

Thanks guys

[Rik]

That extra link will certainly be adding to your ping, unfortunately.

The Speed Test awakens:

Hurrah!  Must have been congestion earlier today; maybe some bits were stuck in a bend.

Thanks

Hmm, spoke too soon - back to slow this morning.  Latency is horrendous, taking about 20
seconds to even get a response from a site. 

Last night around 21:00 everything was blazingly quick, with instant responses.

Perhaps this is an aspect of WBC; reduced daytime performance and better in the evening, to
shape daytime traffic for businesses?  I don't have enough data yet but will keep an eye on
things over the next week.

[Simon]

I don't think it would hurt to give IDNet all call about this. 

[Rik]

I was switched  at 10:37 this morning. Router is a 2700, dual SSID, firmware 5.29.107.12. Downtime was three minutes.

Prior to the shift, my figures were (down/up) attenuation: 57.9/31.5, noise margin: 9/19, sync speed: 3776/448
After, attenuation: 63/32.7, noise margin: 9/5.6, sync speed: 4137/795

Pings have not changed, averaging 23ms, speed tests are the same downstream, about 790 upstream, hopefully I'll get one profile step downstream and gain 500k. The BT speed tester is busy for the moment.

MSAN is a Texas Instruments.


Edit: what a difference a decimal point makes.

[Simon]

[Steve]

  I believe the rise in downstream attenuation is a feature of ADSL2+ as compared with ADSL2 and ADSL

[Rik]

It looks like the BT tester may take a few days to grant access to the new connection, but here's a couple of others to be going on with:

[drummer]

My switch was at 09:15 this morning.  Router is Netgear DG834G v4, firmware v5.01.01.

Previous sync was 8128kbps down/448kbps down, attenuation 26db down/14db up, NM 7db down/24db up.

Sync is now 15956kbps down/1135kbps up, attenuation 28db down/12.5db up, NM 6.3db down 5.6 up.

Pings are 8ms and the Namesco speedtester shows my throughput as 7000kbps down/ 962kbps up.

BT speedtester has been busy all morning so no profile to report but if things stay as they are, it'll probably still be 7150.

MSAN used to be Alcatel but today it's not displaying any vendor ID.

Hey ho.

[Rik]

Pretty good result, Drummer.  I have a theory that the BT tester may not be recognising the new connections immediately, despite the busy message. Time will tell.

I'm still jealous, of course. 

[lozcart]

Switched this morning.  Router is Belkin F5D7633-4, firmware 1.00.25.

Previous sync was 7392kbps down/448kbps up, attenuation 47db down/29.5db up, NM 6.1db down/24db up.

Sync is now 7237kbps down/762kbps up, attenuation 51.5db down/27.7db up, NM 6.1db down 5.3 up.

Pings are 31ms

Sorry don't know MSAN ID
