Hi guys,

Just tweaked mine...

Not sure why the ITU info is 'blank'?

Also feel that web pages loading are a bit more clunky like

Hi all, ex-sky customer now with CiX.

I'm not going to be changing my snr delta on my 130 just yet since i'm having issues but thought i'd at least post my stats currently and then update later when i have a stable line.

used this the other day on my line
was something like 105 attainable in 2013 has slowly been going down
then stabilized at 89 ish attainable then a few weeks ago they turned on the g.fast cab
dropped my attainable to something like 79980000
rebooted the other day and got my first ever non 79995000
was something like 79987000 used -5 to take my attainable to 81572072
back to 79995000 shouldnt bother really as im having g.fast installed in 2 weeks

andy_mk3 · 20 May 2019 at 21:44

Just had to knock mine down to -20, was getting a lot of ping spikes due to errors and was making the internet feel laggy all the time. Taken my download sync from 35mb to 31.5mb. Faster isn't always better

rob77 · 13 Aug 2019 at 21:49

I've got one of these coming this week to go with plusnet fibre. What firmware would you guys recommend? I'm running pfsense and see a BT and an alternative one.

Cheers

ChrisD. · 13 Aug 2019 at 22:04

Use the BT one.

rob77 · 13 Aug 2019 at 22:05

Cheers

Stephanie Peterson · 14 Aug 2019 at 23:35

I just made this tweak to my vigor 130 lifting the sync speed from 42Mb/s to just about 52, picking up a not to shabby 10Mb/s
Dunno what the error rate is like at the moment as i am running the vigor in modem mode off a pfsense VM so i cant actually reach it via the lan at the moment for stats but i will switch out the cables and check it in a few days.

So far though, yep looking good.

ChrisD. · 15 Aug 2019 at 09:19

You can route through to it using pfSense, there's a few guides online.

I tried for hours last night using various guides and I couldn't get it to work. Where you can assign a couple of ip addresses I was missing the options

ChrisD. · 15 Aug 2019 at 10:19

It was so long ago since I did mine and I use a USG now, but I don't remember it being too difficult to do. Perhaps things have changed.

Stephanie Peterson · 15 Aug 2019 at 21:39

I tried a few times and couldnt get it to work either, its totally different in bridge mode as opposed to the old fashioned way of giving a unit a gateway address.
There is prob a way but i dont care enough the now to do it, can just connect the pc to the wan port directly and hit the ip i gave it from there.

Caged · 15 Aug 2019 at 21:58

When you set pfSense up to dial a PPPoE connection it removes the interface from the port, but you can add it back and give it an address without causing issues for the PPPoE dialer.

Stephanie Peterson · 15 Aug 2019 at 22:04

Yep been through that, assigned a Wan subnet to the network port on the back of the server for the modem interface - ip addresses/gateway ect..

Nope.
Pfsense also seems to think the modem has an non routable IP on 169.x.x.x which it tries to poll as a gateway which it cannot reach, the ipaddress of the vigor is not this 169 address (tried it on the local lan, a wan address, a random 192.168.100.x address...) nope
Tried adding firewall rules... nope although the built in wan to any net catch all rule prob should have done it.

On an ECI cabinet and I've got a Draytek Vigor 130 so decided to try this, dropped SNR from 6 to 3 and my download rate has went from 60Mbps to 70Mbps

How are people monitoring this to check for errors and instability etc?

Interesting as the ECI cabinets aren't supposed to be able to drop that low.

I thought they wouldn't by default, not that they couldn't :confused:

I could be reading the stats wrong. I did the tweak via an old laptop and took screenshots, I'll transfer them to usb so I can upload them here.

Use the command vdsl status or vdsl status counts. Should show the stats then, keep an eye on the Errored Seconds.

I'm on an ECI cab, hows your connection holding up with the SNR at 3?

Only did the tweak yesterday afternoon so too early to tell, ran multiple speed tests and it's still 71Mbps down. Watched Netflix last night with no issues. Need to log back in to the modem and check for errors but so far no issues (fingers crossed).
