Devices not connecting to Telstra smart modem 2 after firmware push

[Thorpef1]

Hi everyone. 

Yesterday a number of my devices disconnected from my Telstra Gen 2 smart modem. 

It seems to have completed  an automated firmware upgrade at around 8.30am yesterday as that's when my devices went offline and unable to connect. 

Firmware Number 18.1.c.0443-950-RA
Modem Make Model Technicolor DJA0231

I have tried to reconnect the devices but they do not see the wifi network (yet other devices such as phones, laptops etc connect fine)

Thanks

Luke

The devices that can't connect do you know if the devices that can't connect are dual band or are ones that only support the 2.4GHz WiFi band?

[Thorpef1]

They seem to be only compatible with 2.4ghz

It could be the recent firmware update has caused the 2.4 GHz band to stop working or it could be that the 2.4 GHz might have gone faulty coincidentally at the same time as firmware update. I suggest you contact Telstra support and report a fault with the modems 2.4 GHz band. There have been a few other posts with same problem see this thread.

Thankyou. 

I spoke with Telstra support and after 30 minutes of frustration they agreed to ship a new smart modem. 

Thanks for the assistance

I am  having this same problem.

Do you know if there is a patch of any sorts coming or should I ask for the modem to be replaced.

Telstra has identified the cause of the problem and is working on a patch but I don't know when it will be released.

Good to hear. I have the same issue (from several days ago) and several of my clients who have the same Technicolor DJA0231 modem.

Another client with the same modem had a curious issue that occurred at the same time (as the above 2.4 GHz malfunction), but could also be unrelated - everything works OK (Internet access, I mean) but for some reason ESET Internet Security (running on the laptop, where it's been happily running for months with no issues) cannot connect to the ESET server. Any attempt to connect to ESET opens up the Modem page (192.168.0.1). Just typing eset.com into the browser (any browser) goes straight to 192.168.0.1. Everything else works normally (all other sites.) It's a strange issue. (EDIT. I've checked the hosts file, it's not "poisoned", ie it is normal.)

Try changing the DNS settings in the modem. Change both IPv4 and IPv6 and either reboot modem or reconnect device. This will bypass Telstra broadband protect which as well as blocking maloius sites also blocks other sites as well. There is a drop down menu at Advanced > Local Network with a list of DNS services. See section 33 of document linked at end of this post.
