4G Backup failing

For about the last 60 days NBN connection has been yoyoing. Some days no issues, other days I stop counting comms down after 4 reconnections within 30 minutes. Lodged fault complaint and recently received a new NBN router with 4G backup. This is now in place also experiencing same issues as shown with my previous NBN router [old one did not have 4G capability]. NBN Technician came out the other day and found an issue with the nearest Node which was fixed. My cabling at home has been checked and tested OK. BUT am still experiencing connection fails with the latest router. Now while I'm hoping that service will be clarified soon, have also noticed that the 4G backup is NOT functioning as expected. Modem indicates fair signal strength [3 bars] and I can see on the GUI that it is connecting apparently good for phone but is not providing data on the 4G.

Question: created a new profile for the mobile connection for IPv4v6 blank APN - should I also include the UN & PW for my service?

PS: whilst in middle of preparing this message I lost connection AGAIN

Need to check what my guarantee of service is

Was this helpful?

  • Yes it was, thank you
  • No, I still need help

Re: 4G Backup failing

Starting at the end. You guarantee of service is "best efforts".

 

Is the light on the front of your modem going blue when the landline connection fails?

You should not need to change anything in the LTE backup settings, other than possibly enabling IPv4v6.

Never be afraid to back yourself when trying new things, just always make sure you have 3 escape routes if things go wrong.

Re: 4G Backup failing

No you don't need to provide a login ID and password. APN should be left blank and PID should be changed to Ipv4 / Ipv6. It takes about three minutes for modem to switch to 4G backup after a loss of the DSL link.

Re: 4G Backup failing

Location of router is high up on cupboard so next time I notice that it should be on 4G will get ladder out to check the front LED. Mostly I check from GUI.

Midst replying notice comms down. No LED for Mobile - front LED is amber, then Mobile LED is green and front LED is Blue, but even then there is no internet comms for PC. 

NBN comms now back up and, of course, Mobile LED is blank and front LED is green.

Have noted also the router is reporting 18.1c 0443-950-RB firmware which is not apparently the latest released.

Model is Technicolour DJA0231

PS: comms have gone down at least 6 times trying to reply

Re: 4G Backup failing

Can you clarify - should there be spaces in the PID that is IPv4 / v6 or IPv4v6

I know that sometimes characters and spacing have different effects

Re: 4G Backup failing

 PID should be IPv4v6   - no spaces or other characters..  you should be able to select it from the dropdown list, depending which modem you have...

Re: 4G Backup failing

IPv4v6 is exactly what it should be.

 

Normal you should not have change the 4G back settings. Most device will work Ok with the default settings and it is only necessary to change the PID type if you are having problems with an older device that does not support IPv6

Re: 4G Backup failing

Device supplied by ISP - don't think it is old. Rev 009 DJA0231.

Even when it was left at default settings for 4G the backup didn't work.

Noted that IPv4 DNS primary is set to Telstra [if you leave it blank it defaults to Telstra]

but no Telstra selection available for IPv6 DNS primary. 

If left blank, 4G backup fails. I've set now to CloudFlare 1.1.1.1 & will wait till next comms down to see what happens. If I understand correctly the 4G backup utilises IPv6 so would have expected it to work when left at default [blank IPv6 DNS primary & secondary]

Comms have been sort of stable for last couple of hours.

Re: 4G Backup failing

When DNS settings are left blank Telstra DNS is used.

 

You can test the 4G backup by placing a tick in the mobile only box in the mobile settings. It could take up to three minutes for internet to work.

 

If internet not working could you do a traceroute to google.com and another to 8.8.8.8 and post results? 

 

Below is an example with PID type set to IPv6

Re: 4G Backup failing

There is no option to select Mobile only on the GUI.

To force it to 4G I'll have to physically disconnect the NBN line in & see what happens.

Though when NBN Technician was onsite the other day the process to check & test the line required disconnecting line-in from router - at no time did the 4G backup function work for data, it seemed to work for phone. Will have to arrange to test soon.

Router configured as DHCP & static IPs for the majority of devices.

Re: 4G Backup failing

Your modem must have an early version of the firmware which could explain why 4G backup is not working. Firmware should update overnight but sometimes there will be several reboots when modem is first connected as it updates the firmware. Firmware is displayed on the LHS of modem's log in page. See section 28 of document linked in this post.

Re: 4G Backup failing

Yeah, the router firmware, as shipped to me, is out of date and that is one of the factors I have been researching.

No, it has not been auto-updated even though the router has been in place for 1 week as of now.

Did find an earlier manual than that you linked, and have been referring to it when configuring to my needs [have small LAN]

From my limited knowledge I gather that 4G backup data requires IPv6 service & therein I believe lies the issue.

Re: 4G Backup failing

Well, after 2 x NBN techs later now have stabilized NBN internet comms [ended up changed port connection at the node], then later discussing with support by mobile, an issue that landline phone for voice failing to initialise & connect via router since last Sunday (this had been working fine until then) support finally got around to check backend connection and corrected the issue (problem was not my end, not my handsets and my particular model of handsets should not be paired with the router).

Until firmware on the router is updated [checking version daily] cannot test/check the 4G failover function so this will have to go on the back burner until then.
