Important notes when upgrading to VDSL2 Modem Routers

@ KOPITE,

Excellent piece of research.

Fully support you on keeping the Modem/Router terminating an ADSL line as simple as possible, and setting in bridge mode instead.

Improves performance, easier to undertake fault finding tests, and has security advantages as well.

I use a second router for my LAN and AP's for wireless, with a really simple ADSL modem, and have always had excellent performance out of my ADSL line that way.

Using AP's gives one much better control of Wi-Fi performance with more than one AP instead of trying to use one for a complete home.

Thanks mate, just did it as we don't have anything for modem routers at present.

Doing the same now, splitting my modem and wireless router to handle different tasks simultaneously. Also just ordered an Asus RT AC68U off EBay for a very good price. Just waiting for it so I can hook it up. My billion is abysmal to be honest :sick:
 
Billion 8800NXL

Downstream Upstream
SNR Margin (dB) 12.6 14.9
Attenuation (dB) 0.0 0.0
Attainable Rate (Kbps) 66680 6951
Rate (Kbps) 45055 3072

less than 700m (300 as the crow flies)
Since moving to VDSL, attenuation has always been 0

Weird numbers you got there and something is not adding up here. Attenuation is 0 as you basically live in the exchange :crylaugh:
Your snr should mid 20's to late 20's at least. Too much noise on your line.

Do you have high CEC or HEC errors perhaps

HEC Errors 450413 0
OCD Errors 31 0
LCD Errors 31 0
This over a 5 day period

My ADSL stats on a 4Mb line were
Atten 7db and 2db
Noise Margin 29.8db and 26.0 db

You've got brilliant snr figures mate. Think you have a Broadcom chipset.

Yes he does. Less than 400m is very debatable with attenuation of 21dB but yes very very good SNR. I was on 22dB Attenuation and could not sync @ full 40Mbps speed only 38Mbps so very good stats there.

Thanks guys.
The gestimation on the distance to exchange is based on the Telkom tech. that came through to sort out my line, I also think its a little bit more ( straight line vs. exact traveled route )
KOPITE, thanks for the info on the chipset, based from your listing, I also think mine is Broadcom.

Nice just bought the same router, 20mps vdsl should be installed tomorrow.

Yeh, I'm liking this "badboy" a lot - its simple and does it job nicely ( ok yes, I do miss the USB port than I had on my old TP-Link that the Man above decided to throw a lightning bolt to it )

not sure about distance
 
Attenuation of 31.3dB and getting full speed is really impressive.

And some room to spare on the SNR side. Very impressive. This just proves that you can get good speeds even if you are really far if all the joints are perfect and you have a perfect copper cable...
 
Hopefully it happens :p

Currently get close to line speed on line test and downloads... I'm hoping to bump up to 40Mb once switched.
 
Adsl Line Status SHOWTIME.
Adsl Mode G992.5
Channel Mode Interleave
Up Stream 1020 kbps
Down Stream 20479 kbps
Attenuation Down Stream 23
Attenuation Up Stream 14
SNR Margin Down Stream 6.9
SNR Margin Up Stream 6.5

Just had the line installed today, will phone soon and see if they can upgrade it to VDSL to get faster upload speed.

One would think if it was a brand new line the SNR would be better or was it a old line they just activated for you?

ADSL2+ max speed is 24Mbps, 7dB SNR is due to its limitation. Gtx Gaming will get better SNR when he moves to VDSL.

New line from the pole to my flat yes.

The lines going to the pole is quite old, kinda a remote area. I stay in the only road that has tar, rest of the roads in the area are gravel lol

I am amazed my area even has 20mps dsl/vdsl lol
 
I'm using a Zyxel SBG3300-N
On ADSL
Stay about 800-1000m away from exchange (from what I can tell).
