Two years old and never had a problem – This modem has worked well in my household with 10 wifi and 3 Ethernet connections. Any speed and connection issues have been identified as nbn and nothing to do with the modem itself. And anytime a reset has been required or other issues have arisen, Iinet’s help line team have always been great. Show details · 1
Pretty average and it's the third replacement under warranty – Had connection issues on and off for a while. Done EVERY test advised, moved router, plugged directly into NBN box - even bought a mesh set up... Problem all comes back to the router. And, it seems it's never an iinet product problem - at least until it is, hence, 3 replacements now. Won't be seeking a fourth one. Show details
slow speeds and drop outs horrible! – inconsistent speeds always dropping out i am onto the third modem after two replaced under warranty for faulty wifi cards and i suspect the third is doing the same after 5 months, on lan cable its fine but the wifi is not working anywhere near full capacity of the nbn and dropping out all together. terrible modem it looks and feels cheap get a third party modem Show details

New Modem – Just installed new router and satisfied with ease of installation and connection. Very satisfied with customer service received prior to identify need for a new modem. Have had no drop outs yet Show details · 1
Very Reliable modem – Provided with this modem by Internode. Apart from initial teething issues with NBN, it has worked very reliably. I have 3 desktops(Ethernet), VOIP and 6 wireless devices + an Xbox connected and it has all worked very well. Only times it has crashed (2-3 x) it has been quick to reboot. Booting up itself takes about 5 minutes, so you better… Read more · 1
not be in a hurry! Would have liked to have individual device restriction capacity but otherwise good. It connects to a repeater (TP-Link) to reach the sunroom out the back for the wifi. I can still pick up a connection on my Smartphone when sitting in the driveway, but once outside the front gate it disappears quickly. We get 42/15 service here average here - just used OOKLA now and it read 39/17. Can't complain! Been on NBN for at least 2 years now.
great modem – very happy with this modem for my nbn it is very reliable and quick easy to setup wifi is very quick also on it can enter modem and change passwords and name of wifi and your own wifi password Show details

Easy Set Up But Not A Strong Wifi Signal – Set up was simple and quick, including getting my landline connected and working. But wifi signal strength wasn't much good, especially at the end of the house away from the study where the living room was located. Show details

Poor connectability! Problems connecting wifi printer – Problems connecting wifi printer. Tried several printers - all the same issue of not able to connect WPS key does not seem to provide any assistance. Bought a new HP printer today, checked everything online, all the specs, it should have worked, but SAME Issue - printer recognises every other signal in the street nearly, just not our own modem!

Absolute Junk – Barely has an effective range of more than 4-5 metres, signal is weak and easily blocked by walls and appliances, overheats, regularly needs to be switched off and reset, constant drop outs and slow speeds of less than 1mbps. I have lived in several houses with this modem and this company, all of them hands down the worst, just cheap junk from a bad service provider. Show details

WiFi Range – I have had my iiNet VDSL service now for a few years and I regard it as quite acceptable and took advantage of the WiFi capability. However since the recently supplied TG789 has been in service my WiFi range is really poor on both bands and it refuses to connect to my Solar Inverter which is just 18m away. My next door neighbours router can see… Read more
the Inverter and they are more than 35m from it. I have had no issues with anything which is within 10m, but if your planning on anything beyond that forget it. So the impact of this new TG789 is unacceptable in my situation. It has provided reliable VoIP services, however it does have an extremely limited WiFi range compared to the previous iiNet solution I had which sadly needed to be replaced by this most unsatisfactory WiFi TG789. Sorry iiNet but it an unsatisfactory WiFi solution for the average use!

Dropout every 24 hours – Very consistent dropout every 24 hours, but iiNet support don’t see this is an issue ! Now I just power reset at midnight then go to sleep, and let it restart itself every 24 hours while I slept, so I don’t know there are any nbn dropout ! Show details

You get what you pay for – Its cheap and it performs like that. It doesn't have a very good range, slow to re-boot and lots of connection drop out and resets. We got this from an internet provider as a premium modem but its not that Show details

Poor WiFi Range – I have installed and used several modem routers at my work and home and consider my self an experienced user. The WiFi range and reliability on this modem is very poor. I have essentially given up and will buy my own VDSL2 ASUS Modem Router - I have used this brand before and have been very happy. On one occasion after a years use I had WiFi… Read more
issues on one frequency and ASUS replaced it without a hassle. For basic wired use this modem is fine. For WiFi, unless you're sitting next to it - don't bother.

It is rubbish – The range is not good for a two story house at all and I've been having frequent drop outs daily. I'll admit the speed is good where it is in my room, I get 90Mbps. But everywhere else upstairs and in other rooms the speed is terrible, it gets only 10Mbps. Even my TP-Link range extender I plug into the wall has more range than the actual modem. Would not recommend this product at all. Show details

Not suitable for anything more than the basics – Seems to perform OK as a basic MODEM and VOIP is not too bad. Very slow to boot. DHCP is partially functional. Reserved addresses do not work as expected. In general, crap. Show details

Ultra-low-quality router – We were using this router on ADSL 2+ while waiting for the NBN to be rolled out in our area. Pretty poor range, but it wasn't until we started using it on the NBN that it found a whole new way of disappointing - randomly turning itself fully off (all lights out etc.) and requiring to be powered down and back up again to work. I suspect my… Read more
experience isn't uncommon, because the agent I spoke with at iiNet wasn't in the last bit surprised and I've got another one of these useless devices on its way to my house.

Atrocious. Shameful of iiNet to even provide such garbage – This modem is appalling we got better wifi speeds out of our old net gear modem ten years ago. In fact the wifi has become unusable for the majority of the day/night with it usually reaching speeds no higher than 150kps! Im writing this review using my phone data even though Im sitting right next to the piece of scrap, the only way youll get a… Read more
fairly solid internet connection is by cable. Of course weve been on the phone with iiNet for months now and their customer service matches their poor quality products. Going to now move to another telco. Weve decided that even if we end up buying our own modem we arent sticking with iiNet any longer, they are losing customers that have been with them for over ten years. Disgusting customer service, horrible product, I cannot stress this enough AVOID AVOID AVOID!!!

Terrible wifi range and loses internet connection intermittently – Wifi range is the worst I've gotten out of a modern router. The router actually fails to pull consistent internet from the socket creating significant packet loss as a result so streaming movies or playing games is difficult. Basically even though I have great iinet internet, the content has to continually buffer and loses quality. In terms of… Read more
playing online games, you basically d-sync constantly. Ethernet connections to the router are obviously more stable but still suffer from the strange disconnects just a lesser rate. After researching the router more it seems other people suffer the same strange connection drops. I only purchased this because it is the recommended router from iinet but that was a mistake. Put in the extra cash and go a third party router instead.

Constant Wifi dropout – 3 years ago i moved into a new house and stayed with my internet provider was supplied with this modem. at first i though it was teething problem but over the years the wifi in the house suddenly drop out even when I am in the room with the modem box i get drop out.

help. It at a point that i can't received home phone call the line is so bad as my voice sound gargled and constant audio dropout. I live in a house that is about 25 metres long and it is impossible to get wi fi in the back room in fact it drop out in the living room to to point of frustration. This modem is the cheapest on the market. IInet my internet provider keep blaming my equipment like my phone as faulty it frustrating and if you get this modem don't even bother run a mile from it. They need to start using other modems rather than the cheapest crap. Been a customer for 10 years and it look like I will not be a client any longer because of the problem.

Ok within a small flat - useless around a house – Before I connected to the NBN, I asked my telco how this modem's WiFi would perform, as compared to my (then) existing NetGear router. I was assured that its WiFi range would be a lot better than the NetGear's. It hasn't been. The WiFi range of my NetGear router was perfectly adequate for our purposes - covering a range of over 20 metres. The… Read more
Technicolor modem supplied to us had a reliable range of only around 7 metres, which is totally inadequate for us. I have been trying to sort this out with my telco for the past two months, and STILL haven't been able to sort it out. Trying again tomorrow. UPDATE - Spent too much time, effort and money trying to sort it. We've now decided to change telcos, instead. At least that offers some prospect of having a modem with an acceptable WiFi range.

technition has been suburb and only needed to come once to correct a fault which was in my phone and not the modem2
Opened up a new world of entertainment
Any drop outs I am now able to correct myself by rebooting the system.(not bad technology fo a senior citizen to handle)
Garbage – Was bundled free from iiNet. Performs terrible with wifi. Constant drop outs slow speeds, buffering with Netflix etc. The modem is within 10 feet on the tv. Found this item to be of terrible performance and have just finished throwing it in the bin. I would not recommend this modem to ANYONE! Show details

Absolute junk – I've only owned this for a week and without doubt it is the worst modem/router I have ever owned. I have been completely unable to establish a stable wi-fi connection, I am plagued by dropouts on a daily basis, it requires constant power cycling which takes an age ( maybe 10 minutes) and there's no manufacturer's support. I'm ready to throw… Read more
this trash into the bin or give it to someone I despise but I don't hate anybody enough to inflict this much trouble and frustration on them.
My ISP should be ashamed to be supplying this box of inadequacy to customers.
reliable modem and easy to config – I should say it is one of the mid range modem in Australia. good user interface but not advanced and very easy to config your NBN Provider. low price and good WiFi range in small house, suit for one story! at overall it is good and cheap modem for home use. Show details
Delivers faster speed than my asus dsl ac68 – Having this unit on ADSL2 before HFC connection I have found the Wifi to be as good as the Asus modem router. And both download and upload speeds are on average 30% faster!! Point off though for configuration being locked down by supplier. So doesn't show some functions.This unit can assign static IP addresses. Show details
No internet – Just moved houses and have tried to get internet in the house for over a month now and have called optus about it and nothing has be done. I don't know what's wrong whether its the modem or just the company I'm with but I'm not satisfied with either because still i have no internet. Show details
Good – Fast enough. Holds multiple connections. Isp edition is easy to set up. Had a lot of issues with dropouts with this modem on internode. Was supposedly fixed by a firmware update. I would strongly suggest that you make sure the firmware issues have been resolved before buying one of these though. Show details
Even free this modem is not worth it – Four weeks ago I replaced my ever faithful ASD2890AL because I now need a VoIP modem. I don't think a day has passed that the WiFi has not dropped out (and often). The sync with the ISP is OK and has been up for over 2 weeks, but it just can't handle the WiFi. There are 11 devices connected, but even when I work from home with 1 active device I… Read more
get dropouts and it will take 10-20 minutes to get a stable connection again. Glad I didn't pay for it. I am off to get a proper modem.
Perfect – Has worked perfectly for 18 months now and has much better wifi than the Billion 7800NXL it replaced. I used to have to use a wifi repeater half way down the backyard of my back neighbour who I share my broadband with but don't need that anymore with the TG789. LIttle slower to reboot than some modem/routers but not slow enough to matter. Show details
Modem nbn – This modem I bought through iinet for my nbn set up haven’t had it long but seems to be alright. We can have 7 devices hooked up at once and seems to hold up alright. Light weight and keeps itself cool, use it standing on its side or laying flat whatever you prefer Show details
Works perfectly so far – Router came with My Republic Cable NBN Easy to set up and use I have 43 connection in my house About 15 on the Lan network, approx 28 wireless depending on what's turned on or in range. Most wireless connections are Sonos type switches and Harmony hub controlled hi fi etc I mounted the white coloured Router 1/3rd the way up the wall where the… Read more · 1
cable connection comes in
Found it gave better coverage off the floor or desk
Spaced it off wall about 10 mm to aid air circulation
I have 2 lan wired switches to aid with lan distribution
Good modem provided by ISP – I got this modem from my NBN ISP. In general works fine although the dual wireless signal is not very powerful to cover all my house. My previous D-Link modem-router used to do that, so now I need to buy an additional device to cover my whole house... Easy to install and setup. I get normally very good download speeds trough my ISP and this modem hadle it well. Overall it was for free and does the job. Show details
Good modem, basic only wireless router - overheats in sub-tropics no aircon – I got a TG-789 for free from my ISP when I switched to the NBN (FTTN). Modem It synchronised at 69.3/41.69 Mbps at our house (the fastest speed it could connect at download/upload) which was good for my distance from the node. The upload sync speed is faster than another modem I've since bought, the TP-Link VR2600, syncing at 76.6/34.2… Read more
Mbps. The TG-789 has a higher upload, while the VR2600 has a higher download sync. Most would prefer the download to be the priority over uploading, though (hey still much better than ADSL I used to only get 6/512!) Adding both upload and download the TG-789 is squeezing more overall, out of our connection.
The internet only dropped out a few times that could have been other problems (unlike the budii lite I tried also, which dropped internet multiple times a day!). I did see some errors listed though, many downstream FEC errors per day (around 30) and upstream and downstream UAS are both: 141. My ISP said not to worry about those so long as the connection doesn't drop! I don't get any FEC or other errors on my VR2600 though.
It worked successfully with Aussie Broadband FTTN too when I changed ISPs.
Wireless Drop outs
The TG-789 is a good modem, however, why we upgraded, and it is now a spare, is it had many wireless drop outs. We have a Wii U in the same room and multiple neighboring wireless networks interfering. The wireless dropped every few days. It seems to support only 10 wireless devices too and when you connect over that the drop outs occur. Being a three person house with a geek (me) and a teenager 10 isn't enough for us!
Also the wireless dropped out and the whole thing froze whenever I logged into the management interface and applied settings.
Overheating?
I believe the wireless worked well for the first three days but the semi-tropical, non-airconditioned environment in summer here may have got to it. (in our lounge we get near 40C sometimes and frequent high humidity) Then the wireless drop outs started. I ended up putting it up on a mesh stand and a small fan blowing up underneath it. It has good ventilation holes all around but perhaps isn't heatsinked enough. One clue, is how light it is.
If I had a good router already I would have bridged the modem to it (made it so the modem is just a modem and the router function is done by the router). I ended up getting a modem/router to take over it's job but also had to get a VOIP ATA for land line phone. The TG-789 does have VOIP capabilities built in, and I could have used them for my non-isp VOIP service ok as it's unlocked, but if you bridge it, you'd lose the VOIP function too. Then I would have needed three devices, unless I'd got a modem/router with VOIP built in.
Pretty good – Pretty good considering it was provided by ISP. I have had no problems so far and it is very easy to set up. Easy to use and it works on wireless but I do not know about wired connections for I have not tried it. Overall a good modem with good service Show details
Good modem, provided by ISP – This modem was provided to me as part of my plan with my ISP. I've used both wireless and wired connections, and used it with both ADSL 2+ and NBN (FTTN) - and it hasn't missed a beat. I find that it doesn't really reach up to the very end of my (long) house, but I don't use wireless there anyway. All good! Show details
