Yesterday, Telstra disconnected my landline and ADSL even though the NBN technician is not due to arrive for another 6 days.
I have the Telstra Arcadyan LH1000 modem running the following versions:
Was this helpful?
The most likely cause is that NBN has not yet fully activated your service.
Thanks - NBN won't be installed on premises for another 6 days, but doesn't the 4G fallback work even for ADSL customers ?
Your ADSL previous service has no connection/relationship with anything NBN.
You'll need to set up your mobile phone to be a hot spot until the NBN is officially activated.(but monitor that the mobile data you draw is within your allowance).
You should be able to access the internet over the 4G backup while waiting for NBN connection. What colour are the Online, Wireless Mode and Wirless Signal leds on the back of the modem?
My modem pre-dates my request to transition from ADSL to NBN (the modem was being used for ADSL). Are you saying that because they have disconnected my landline / ADSL connection that they have also fully disabled the use of my modem to access the internet?
The led on the front is blue. All leds on the back are green. The led that indicates the modem is using "mobile mode" is green.
When I access the modem web interface, it shows that the modem is in
The WAN / DSL light should not be green. If the DSL port is connected try disconnecting DSL port on the modem.
On 4G backup the modem will only have a WAN IPv6 address, but internet should still work. Has the modem ever worked on 4G backup?
In one of the premium support calls, they asked me to disconnect the DSL port - that led does go out when I do so. Then did a hardware factory reset. Neither option made a difference. In the next premium support call, they asked me to reconnect it. Led comes back on.
The modem has never worked on 4G backup.
I've just tried removing the PSTN as well. Another led goes out (Phone). I'll try another reboot.
You might have a faulty modem or Telstra might have configured 4G back incorrectly. I don't have one of those modem's so I don't know what settings can be changed but these are the settings.
Data APN: telstra.hybrid
PDP Type: IPv6/IPv4
Thanks cf4 - that made a difference but still not fixed.
Data APN: blank
PDP type: IPv6
Now, after a modem reboot, it has WAN IPv4 as well as WAN IPv6 address. Plus an IPv4 gateway address and IPv4 DNS addresses
Here are the ping / ping6 results:
WAN IPv4 address: Yes
WAN IPv4 gateway: No
Internal modem IPv6: Yes
WAN IPv6 address: No
WAN IPv6 gateway: No
Maybe I'll try changing the Data APN but leave PDP type as it was (ie no IPv4)
No - DSL & PTSN are disconnected as you advised previously.
Reverting PDP type to IPv6 only kills all the IPv4 addresses in the modem (WAN, Gateway, DNS) but make no difference to accessibility of IPv6 addresses (can reach internal modem IPv6 but not WAN or gateway IPv6)
I am unable to ping the WAN IPv6 address of modem but can ping external IPv4 and IPv6 address from connected devices, but can only ping IPv4 addresses from using modems ping tester.
Thanks cf4, I reverted to PDP type = IPv6 (ie no IPv4 addresses like your screen shot), but still can't ping google dns on IPv4 or IPv6 (126.96.36.199 or 2001:4860:4860::8888)
I see slightly different DNS entries on the modem but that's no big deal.
Under "Connection mode" I see "Current Mode: LTE routed mode" rather than "Type: Mobile" as per your screen shot.
I also don't get the message "Your broadband service is working in backup mode ..."
My IPv4 entries show blank rather than 0.0.0.0 (slightly different firmware or different modem behave differently?)
Something else I've tried:
Under Advanced -> Internet -> Internet Access there is a option called "WAN Supervision" which can be:
BFD (Which the modem's online help describes as Bi-directional Forwarding Detection)
I've tried all 3 options - no difference.
I think the differences are due to the difference in firmware. The advanced settings page for the Technicolor modem is very different fro that of the Arcadyan modem.
Have you checked at Telstra My account that your service is still active and has not been disabled. The problem is probably either a faulty modem or the way telstra has configured your 4G backup.
"Unlimited Internet" plan still active in My Account.
Thanks for helping. Back to tech support....
