Telstra smart modem gen 2 fault

Answered
I switched to Telstra broadband 3 weeks ago and receive a Telstra smart modem gen 2. The first week after it was set up the connection dropped out a couple of times and I had to restart the modem to regain connection - however I can’t be sure how often it did drop out as I only used it with my phone or my iPad - both of which had sims to back up to when wifi dropped off. About a week ago I bought a smart TV and since then my broadband has been largely unusable. I have lost count of the times I have had to restart the modem. Even after restarting it loses connection after less than 10 minutes. I have tried logging in to the modem settings but there doesn’t seem to be anything I can do - the settings state that the connection is working fine. All the lights are green on the modem but i still get an orange message saying “no internet connection” on my phone and iPad when I try to access the wifi and no connection at all through my smart TV and my google home mini. Can someone help me please.

Re: Telstra smart modem gen 2 fault

An update on this. I have since had a tech visit after which it became apparent that the fault was with my modem. I've now been sent a new modem and I am back online. All devices connecting perfectly - including my google mini home. Thanks all for your help.

  • Yes it was, thank you

Re: Telstra smart modem gen 2 fault

A lot off people are having trouble with the Gen 2 modem maintaining a WiFi connection. Try turning of both Google Home mini, smart TV and reboot modem. If phones stay connected for over ten minutes turn on the Google home mini and then after another 10 minutes turn the smart TV on and see if either one cause the phones to drop out.

The smart TV if it supports miracast or chrome cast creates its own wifi network on the same channel as the modem. This shouldn’t but could be causing the wifi devices to drop out.

Re: Telstra smart modem gen 2 fault

Thanks for the reply. Not sure if this helps you diagnose but I’ve turned off google home and smart tv and rebooted modem. The wifi is back and phone able to connect but iPad cannot connect. Turned on google mini after 10 mins and google mini unable to connect - although, unlike before, the phone remains connected. I should mention I had a Chromecast as well which I turned off and disconnected yesterday after reading one of the comments on this forum that said chromecast might be at fault.

Now turned on smart tv as well - and although my phone remains connected to wifi - I cannot connect smart tv or Telstra tv.

Have you tried rebooting the modem and leaving Smart TV and Chromcast disconnected and seeing if other devices remain connected or can connect.

Re: Telstra smart modem gen 2 fault

Is there a setting I need to be on with this modem. I have tried different options - disabled band steering, disabled 5ghz, change channel from auto to 6 and then to 12. Nothing seems to work. In fact it seems to be getting worse. I used to be able to connect to tv for a few minutes immediately after restarting the modem. Now even if I restart the modem I only get a connection on my phone and that too only for a few minutes. No other devices can connect at all - including iPad, google home mini and smart TV.

Re: Telstra smart modem gen 2 fault

The only real solution is a modem firmware update but firmware updates take time to develop. The reason for drop outs has to be determined then a solution developed and the update has to be tested before it is released.

In the mean time you could you could try setting up a static  IP address and custom DNS on your device and turning off LAN IPv6 (Advanced > Local Network as per this post

 

Ip address 192.168.0.xx were xx is a number between 2 and 254 each must have a different address.

Network mask 255.255.255.0

Gateway address 192.168.0.1

DNS 1 8.8.8.8 or 1.1.1.1

 

Google your device to find out how to set up a static IP address. Unfortunately this want work for google chromcast as I don,t think they have this feature.

Re: Telstra smart modem gen 2 fault

I believe these Arcadyan Smart modem V2 units have bad firmware.

Ever since I got NBN in December and had this Smart modem V2 connected I had rebooted it 16 times in 4 days to restore service. Symptoms included: delays in web browsing and some pages timeout, cant bring up routers web interface when router fails, cant bring up Telstra speed test site and when it does come up its the Perth server which doesn't work. Intermittent connection to game servers.

I connected my old router  which I used on cable broadband and worked flawlessly for the next week.

I got Telstra to send me another modem and the placement V2 and it had exactly the same faults as the first.

I then got them to sent out the original smart modem V1 and this unit has been working well  so far.

Re: Telstra smart modem gen 2 fault

I have now disconnected my google mini home, thinking that was causing the issue. I have also set static IP addresses for my TV, phone and iPad. I thought the issue was resolved when the connection stayed on for half a day. However, this morning the connection has again dropped off on my phone and iPad - with both saying: No Internet Connection against my wifi network. This is despite restarting the modem twice today. Strangely my TV remains connected. I'm now concerned that I might be exceeding my mobile plan limit as my phone, iPad and laptop are all unable to connect to my broadband. This is especially frustrating since my broadband is unlimited. I cannot take advantage of the unlimited data and instead end up using my limited mobile data. If this impacts my next bill I will be lodging a complaint.

Re: Telstra smart modem gen 2 fault

Yes, I think if I was you guys I would get another modem and use that for the time being until you see/hear that new firmware has been released. There are a few Telstra Frontier modems going for a good price on eBay atm (Remembering you need a Telstra modem if you want to use the phone on the NBN).

It's always a good idea to have a backup modem for testing anyway.

Trouble is, we don't know when an update/fix for the current problems are going to be released?

The cable adapter is the small netgear cable modem that connects to the coaxial cable connection on the wall. Your Telstra modem should connect to the netgear cable adapter.

Re: Telstra smart modem gen 2 fault

I just today plugged in the Gen 2 modem Telstra sent me to replace my old modem which was working OK apart from consistent and untimely dropouts together with the wall power socket blowing up. Seriously dangerous situation.
In any case, plugged in the Gen2 - all seemed to working fine for 5 minutes then nothing. Trouble shot a number of times, also with a Telstra phone help adviser and the modem was all over the shop. All lights GREEN yet at some times was getting snails pace bit download other times, great download and then most of the time nothing. It's a crock of **bleep**e. Have read the forums and it seems that the Gen 2 is riddled with issues. Reconnected my old modem and so far no issues yet there will be the inevitable dropout. It's unbelievable that this can occur at such regular intervals with Telstra. Unbelievable. Gen 2? yeah my arse!

Re: Telstra smart modem gen 2 fault

Sorry to hear your having problems but it seems  be a common problem.

I had same issues on gen2 with all lights green and no access.

Do your Gen2 issues occur on a wired Ethernet connections and wireless as well ?

Are you able to  access the routers web  interface on http://192.168.0.1 when the loss of internet access occurs?

Are you able access https://speedtest.telstra.com ?

Re: Telstra smart modem gen 2 fault

I had the same problem with Telstra Smart Modem Gen 2. I got my modem about 10 days ago. I have had nothing but problems. I have had intermittent problems with my older Telstra modem, a Thomson TG782T. I have had the older modem for more than 10 years. With the Telstra Smart Modem Gen 2, the internet would work on devices for about 3-4 minutes and then it is 'lights out'. Modem front panel light is green showing that it is connected and everything is fine. After a frustrating experience (switching modem on and off, resetting), I have gone back to the older Thomson modem today. So far, no dropouts. It might be Telstra got a bad batch of modems but it certainly has wasted my time. Being tech savvy, I hate going through the laborious troubleshooting process with Telstra tech, not to mention the long wait before you speak to someone.

Re: Telstra smart modem gen 2 fault

Don't waste your time rebooting or resetting if the problem is persistent. In addition to Wifi, Wired internet connections displayed the same dropouts with the Gen 2 modems. I could not even connect to the modem from my wired laptop using the modem ip address (192,168.0.1). Everything shows that my computer is connected.

Re: Telstra smart modem gen 2 fault

So that we can provide feedback regarding these devices to the relevant team, it would be helpful if you included the following details if you are experiencing this issue:

 

1. There are two different modem models that are referred to as Telstra Smart Modem Gen 2 and they also have different firmware, so please advise if you have the LH1000 or the DJA0231

 

2. The firmware version that your modem currently has. You can locate the firmware version by accessing the modem page at http://192.168.0.1. The firmware version should appear on the first page by the Gateway Information. Customers with the LH1000, the password to log into the modem is: Telstra

 

3. Have you tried disabling Band-steering (located under WiFi- in the top menu) and the IPv6 State (you will find this option under Advanced, then Local Network)

Re: Telstra smart modem gen 2 fault

FYI

In my case, both gen 2 modems I received are:

Arcadyan 

LH1000
Boot version: 1.0.38-116.118
Firmware: 0.05.04r
Hardware: 01

 

It made no difference switching off band steering on WiFi .

In my case internet connectivity failed whether you where on Ethernet or wifi.

 

Disabling IPV6 also had no effect. Within 10 minutes of booting up this modem

again I lost internet connectivity.

 

Reconnected my gen 1 Technicolor DJA0230TLS modem and its been working flawlessly.

Re: Telstra smart modem gen 2 fault

Hi Ator,

 

I'm sad and glad that I am not the only one with this issue.  I am on my second modem now and after NBN tests reporting no fault I'm now waiting for someone to call me (after 6pm tonight. what a surprise for them that while I'm at work that I cant access the modem) to fault find some more.

 

The exact same issue, every 10- 30 minutes I have to reset the router to get access to web pages and the router menu.  I've just switched to Telstra in December and have had the worst time porting telephone numbers, this modem issue just puts a cherry on top.

Re: Telstra smart modem gen 2 fault

Well they will try and fault find as part of their procedure every time you call.

For me after the second call and second  modem, I insisted they send out yet another modem.

It was purely by chance that this time they sent me the older model "Telstra Smart Modem DJA0230TLS Technicolor" and it worked. Looks like this

https://www.productreview.com.au/listings/telstra-gateways-frontier

 

In my case I had my older Telstra Gateway Max Cable Modem (Netgear Model) and I configured it to WAN mode and plugged it up to NBN box and worked as well, while I waited for new modems to be posted out. Off course the home phone wouldn't work as 

they weren't capable..

If you have an older modem with a WAN port on back you may be able to do the same.

Re: Telstra smart modem gen 2 fault

I agree, the Arcadyan Gen 2 firmware v0.05.04r has issues !
I am connected via copper to a FTTN.
I have observed that devices connected to router using UPNP will stop functioning in time.
Trying Power Off/On the Router doesn't fix issue, but if you reload router factory defaults or your router (pre)saved configuration file it does. [ If you have customised router settings, be SURE to Save the modem configuration file to your PC so you can re-load it if necessary !!! ]
When my Arcadyan Gen2 first arrived in late December 2018, it came pre-loaded with Firmware v 0.04.14r, then there was an overnight automatic upgrade to v 0.05.04r. I quickly learned that the new firmware was NOT at ALL compatible with the old versions configuration file ! ( Devices would connect to router, but then claim "No Internet Connection" ! The only way to recover a working network internet connection was load factory defaults into the Modem from admin login and then re-write all customisation's.
I find it interesting that when Telstra roll out a Network wide NBN modem F/W change, that they could miss this configuration file compatibility issue ! ( in other words, the F/W upgrade script has bugs ! )

Re: Telstra smart modem gen 2 fault

I would not be surprised if Telstra re!over the backup function in a future upgrade. Telstra removed the backup function on the F@st5355 because it was causing problems.
Have you tried turning UPNP of in the modem and manually port forwarding required ports to see if that fixed the problem of devices losing connection.

Re: Telstra smart modem gen 2 fault

I have been working with a Telstra consultant and I am trying something out which may be beneficial for others having issues with their modems and dropouts.
TURN TELSTRA AIR (TA) OFF!
It could be that TA is actually fighting for space inside my LAN and therefore will knock the signal out from my NBN box to the router.
I will know for certain if this is the case when I reattach the Gen2 modem which after the first initial connection died in the arse. And it may explain the consistent dropouts we have been experiencing with our Telstra Gateway modem.
Will post soon!

Re: Telstra smart modem gen 2 fault

There are two companies making the "Telstra Smart Modem Gen 2". The modems made by Technicolor, the DJA0231 model, is definitely much more solidly built and more reliable. They look almost identical on the outside, but the modem manufactured by Arcadyan has very poor build quality, even the SIM cover doesnt sit in the unit nicely. The Firmware is very poor on the Arcadyan unit also and lacks features the Technicolor unit has.
Unfortunately you dont get a choice which one is sent out. I had an Arcadyan built model, and this was the biggest pos I have ever had, and I am someone that has always stuck with the Telstra issued modems right back from when Technicolor were still called Thompson.
The Technicolor "Smart Modem Gen 2" is a brilliant device by comparison. Solidly built, buttery smooth firmware, nice feature set for an ISP issued modem and good WiFi strength.
I don't know why Telstra didn't stick with Technicolor alone. Going with two manufacturers has just caused headaches.
