Australian NBN & LEDE

Hi All

Recently picked up a Netgear DM200 and had no end of issues with DSL dropouts. Someday we're talking 10 – 15 for around 5 minutes each.

Decided to see if OpenWRT (LEDE) was available as I use that on our router and its great.
Loaded openwrt-18.06.1 onto the modem.

Now DSL doesn't connect at all and I believe it's my settings. *FYI we run a FTTN, static IP w/ Aussie BB

Network -> Interfaces

DSL

Annex – A + L + M (all)
Tone – Auto
Encapsulation Mode – Auto
DSL Line Mode – VDSL
Downstream SNR Offset – 0.0dB

VCI – 35
VPI – 08

Encapsulation Mode LLC
Forwarding Mode: bridged

So the question is, what on earth am I doing wrong? DSL Light flashes twice in green every 10 seconds or so, however, the DSL Stats which I'll include below show there is no DSL connection in any shape or form. Our old MyRepublic modem works just fine, same cable, same port

Any help would be great

Thank you

Are you sure that the NBN FTTN tier actually uses ADSL/ATM? From glancing at https://www.nbnco.com.au/residential/learn/network-technology/fibre-to-the-node-explained-fttn.html I would have guess that they use VDSL2/PTM instead... now which vdsl2 annex applies in I have no clue, as nominally none fits (Annex A being for North America, Annex B for Europe, Annex c for Japan), but I guess according to https://whirlpool.net.au/wiki/vdsl2_modem_routers_isp_settings starting with Annex B might be okay.

Good luck.

In addition to the points @moeller0 mentioned, you probably also have to supply a vectoring enabled xdsl firmware blob and configure the correct vlan tag for your connection.

You might find the info in this Whirlpool posting and some subsequent postings in that thread of assistance in getting 18.06.1 on the DM200 to connect on NBN FTTN.

@pythonic

Thank you for showing me this. It seemed to have worked with a couple of adjustments!

I'll post it the steps here in case anyone else falls into the deep end like myself.

Download the xdsl driver from the netgear site here:

https://kb.netgear.com/000054455/DM200-Firmware-Version-1-0-0-52

Extract the .img file using 7-zip. You should get the dsl driver file named 'dsl_vr9_firmware_xdsl-05.07.0B.05.00.07_05.07.05.04.00.01.bin'

.Copy this file in /lib/firmware where you will find other xdsl drivers using WinSCP w/ default port

Configure DSL:

Annex: B (All)
Tone: B43CB43 + B43C + V43
Encapsulation mode: PTM/EFM (Packet Transfer Mode)
DSL line mode: VDSL
Downstream SNR offset: 0.00dB
Firmware File: /lib/firmware/dsl_vr9_firmware_xdsl-05.07.0B.05.00.07_05.07.05.04.00.01.bin

VCI: 35
VPI: 8
Encapsulation mode: LLC
Forwarding mode: Bridged

Under Interfaces adjust WAN (which is DSL) to whatever your provider uses, in my case w/ Aussie BB i changed it from PPoE to DHCP Client.

REBOOT

Wait.... and you'll be up and running.
