We had a line fault and no adsl for almost a month at our holiday house, Glinks Gully. Chorus had to dig up the road and it's finally back on but the line speed has dropped from around 7mbits to a little over 4mbits, also syncing on adsl1 now and not adsl2+ where it was previously. When we first got broadband installed here back in 2014 we got just over 10mbits.

2 Degrees (ex snap) checking in.

Went from 8b to 17a overnight.

DL 47->55

UL 9->24

Can't complain about that - free upgrades FTW.

Um...feels weird to say it, but "well done and thanks Chorus!"

;)

Ours also increased within the last day or so (can't remember if I checked yesterday).

Pre Sync Down/Up: ~63Mbps/~13Mbps

Pre Speedtest Down/Up: ~58Mbps/~12Mbps

Post Sync Down/Up: ~83Mbps/~38Mbps

Post Speedtest Down/Up: ~75Mbps/35Mbps

We seem to have had a nice (initial) bump to speeds for sure. Will be interesting to see whether the DLM downgrades that in the coming days.

My line reconnected at 1am this morning in preparation for the upgrade next week. Went from 50/10 to 70/30 (likely 8b to 17a) leading me to believe it's on an Ikanos card.

Here are my stats:

PC: 5800X3D/32GB/RTX3070

Car: Toyota Celica GT-Four ST205

Went from ~40/7 to ~40/12 overnight. The bigger change was rewiring last month taking us from ~35/2 to ~40/7.

My connection also changed last night. Unfortunately I seem to have gone from 43/9 to 35/10. Losing 20% download is a disappointment. Although my biggest disappointment is I'm still over 2yrs away from getting fibre!

That's nothing. I've lost over 50% of my download speed and gained nothing on upload.

I would reboot my router but worried it might affect DLM training.

How can I switch back to previous profile?

You can't. Leave your modem alone and pray to the DLM fairy that it reverts.

Went from

8b 60/10, snr 9.2db, att 12.6db

17a 70/30 snr 14.9db, att 15.2db

The attainables also went up to 92/33, curious that the snr and attenuation changed by that much.

snr is running high as you are maxing out the available speed on your linecard.

my line is yet to move to ddDLM, am interested to see what it does with longer lines...

Hopefully by then chorus have fixed my fault rather than claiming NFF....

Hi,

Yep, master filter installed from day one. VDSL has been stable and working well for a couple of years. Always got around 45-50Mbps down and 8Mbps up.

I also notice that upload speed has reduced to just under 1Mbps

Nothing has changed on my network, as I said the DLM changed overnight.

Smokeping showed a little blip in their connection:

Speeds have vastly improved - have got a Raspberry Pi there for off-site backups and did a test. Was able to max out the 100Mbit Ethernet on download and got 43Mbit on the upload.
