I have been using Linksys WAG120n. It's been working fine with Orcon. It's 100% functioning until i reset the modem (forgot admin password). I followed the basic setup for NZ internet (RFC 2363 PPPoA, VPI=0, VCI=100, VC for multiplexing, Multimode for DSL Modulation). I entered my username and password but the DSL and Internet lights are no longer on (literally 2 min before the reset i was surfing the internet). Usually thoses two lights are green.

So i unplug the power for 5min and restarted the modem. The DSL and Internet lights flashed red and orange a few times then went off. Internet was still off. I repeated this process 5+ times, resetted the modem 5+ nothing helped.

The wireless function works 100% though. I have a bad feeling the modem died just unlucky because the phoneline still worked.

I have done some search on the net a guy said it might indicate the modem has problem.

Anyone has any idea?

Is the DSL light on (solid)? if not either the modem is buggered or you have line fault. Try another modem and then check all your line cords, jacks etc.

Both DSL and INTERNET lights should be on solid.
In the case of the OP, it does appear the modem or the line has failed.

The following is the 'working' mainstream configuration setup for the WAG120N DSL interface.

Encapsulation: RFC 2364 PPPoA
Multiplexing: VC
QoS Type: UBR
Autodetect: Disable
VPI: 0
VCI: 100
DSl Modulation: MultiMode (Can use ADSL2+M, but gives no upload benefits)
User Name: user@xtrabb.co.nz
Password: IHateWAGmodems
Keep Alive Redial: 30sec.

My Linksys WAG120N gives me the best download bandwidth compared to the following modems:

Approx 1Km from exchange
VDSL2 filter in place
CAT5 cabling to the modem.

Using Speedtest.net via 10/100 Ethernet the following is seen.

Linksys WAG120N = ~ 12500kbps
Thomson TG585v8 = ~12000kbps
TP-Link TD-8840T = ~10800kbps
TP-Link TD-8840  = ~10800kbps

Line stats as seen on TD-8840T

Downstream / Upstream    
SNR Margin: 11.2 / 13.4db
Line Attenuation: 21.8 / 13.6db
Data Rate: 12741 / 948kbps
Max Rate: 15480 / 937kbps
POWER: 19.3 / 11.3dbm
CRC: 0 / 0

If the Linksys WAG120N has gone belly up, at least one is presented with the opportunity to upgrade to a TP-Link TD-W8960N modem, which is reported to be one of the better all-round modems/routers.

The Linksys firmware is limited (I'm being polite) and the WiFi on the WAG120N is total carp.

At 15m(3 walls) the WAG120N can not hold a WiFi connection.
At 15m(3 walls) the Thomson TG585v8 can hold a connect and returns a speedtest.net throughput of 11635kbps
At 10m(3 walls) the WAG120N can hold a WiFi 20MHz connection, but only returns ~7000kbps on WiFi  to a 12000kbps DSL line.

Client is an Android v2.3.3  802.11g 54Mbps device using speedtest.net

I'm a bit of a Thomson TG585v8 fanboy.

Good points.

In a stable DSL environment the broadband connection is very good.
Command mode gives access to VLAN IP subnetting and routing, but not for the faint hearted.
Reported to be able to configure a half bridge connection (I've not tried it)
Supports NAT/forward of PPTP and OpenVPN.

Noted problems with the Thomson TG585v8 are:

At 24W of power it uses twice as much juice as any other modem.
NTP time can not be dynamically maintained without manual configuration.
syslog can not forward on UDP port 514.
802.11n 65Mbps WiFi limits bandwidth when range extenders are used.
May have issues with Apple products, but I have no apple products so can't say.

Yes, true, more info than one needs to know, but I feel if I've stopped someone buying a Linksys WAG modem, I in some way have helped make the world a better place.  Laughing
