It came as a package when we signed up with Telstra NBN. Easy to setup, literally a plug and play affair.
I'm happy with the back up Sim just in case we loose NBN connection. If it goes on backup mode, Telstra will contact you and try to fix your connection issues. This happened to me without even calling them. How's that for service!

The modem will only switch to 4G backup when there is no Broadband signal. When signal is so low that your devices tell you you have no wifi.... Telstra smart modem does not kick over to 4G.
Basically needs threshold raised off zero.

Received the Telstra Smart Modem Gen2 when we cutover to NBN in March. It is excellent compared to our previous Telstra Gateway Max modem. It was easy to set up and the wifi coverage is better then the Telstra Gateway Max. We have no issues with the modem and is very happy with it's performance so far.

14 month now with NBN with new modem g2 it’s fantastic speed been with Telstra 15 years now kids very happy with online gaming Foxtel Netflix cctv system and security system are great now, BEFORE WE had the ADSL2 it’s very hard to view cctv and we can’t run 4 devices at the same time

The modem is sleek and fits in your house very well, the Internet speed is usually pretty fast, however the connection drops out at least every hour, and I need to reset the modem, which gets kind of irritating when I'm in the middle of something.

I signed with Telstra years ago in 2014, the first device Technicolor TG797n was great. Noticed the network keeps dropping contacted Telstra and signed NBN FTTC plan in January 2020 hence got a replacement Smart Modem Gen 2, surprisingly it's so bulky, the power adapter has also changed you can't re-use the previous one. Performance wise it works ok, but when the internet is down the backup 5G is slow. Considering it's free with my bundle plan it's average product.

Brand new GEN 2 which only works on 5gz and not 2.4. So reverting back to my old modem. Thanks Telstra for wasting a day of my time. So basically don't bother with this.

I was quite impressed with this model device (LH1000), easy to set up, excellent user interface and enough controls to be useful. Also it has very strong wifi throughout my two storey Villa. The device is 6 months old and the wifi has died gradually, weaker and weaker signal, until nothing. I'm waiting for Telstra to provide a solution.

Recently got Telstra nbn and now I get constant drop outs and like most others are saying when this modem swaps to the mobile network it's absolutely useless & non-existent. The wifi is terrible - it only works when you are right next to it.

Modem is fast, Has strongest wireless signal I've ever had from a Telstra Modem, 4G Backup is a nice feature for those on unreliable HFC NBN connections but its limited to 6/1Mbps speeds should be made sligthly faster.

Unfortunately the manufacturing process is letting them down I was told that I needed to replace my modem even though at the end my original was working fine. The replacement I got was very buggy and the 4G module kept diapering after 48 Hours and would go slow another replacement was sent out after much discussion and has been fine ever since.

This modem does not work. First problem was always restarting. It would just turn off then take ages to restart. Second was the wifi just stoppped working altogether. Will never turn on after that.

Telstra provided this modem as a free replacement when the old one stopped working, probably because of ADSL line quality deterioration. In my opinion, they offered the new modem instead of fixing the line. Anyway, the new modem is extremely good. It synced on the existing line and speed was good. Wifi is very good throughout the house. The 4G backup is also very good but too slow to use instead of the fixed line service.
No problem with placement of status lights .. there is one on the front that changes colour if there's any problem.
Overall, a first-class, modern product.

Forget the performance and the rest, who would design a modem with the all the status lights on the back face where the leads are plugged in! Aren't those the lights one wants to see when we are checking the status?
And where is the on/off switch? Is it the WiFi switch?
Maybe the Gen 3 will return to a sensible design.
