Appears to be a crippled product, no AI mesh support after 3 years.
The specs are good, however the modem firmware is ancient and there is absolutely no AI mesh support. WTH Asus, there are cheaper models that are better maintained? Avoid this one.

The device has good hardware with support for Gigabit Ethernet and 1024QAM. The range is very good and can support multiple devices. My only complaint would be the inability to filter HTTPS websites.

Had this unit for about a year now and it's plagued with constant disconnects and wireless issues. It's really unfortunate especially for the price I paid for it. Read reviews before buying!
This is trash
This modem/router is incomplete. The firmware hasnt been updated in over a year and it is STILL missing features that $50 modems have. The traffic manager cant manage anything, you can put some priorities for upload... and that is it. No download management or throttling. For a $400 modem/router.
Its also has a memory leak if you enable to AI features so you cant use them unless you want to be resetting your modem constantly. This product is trash and should not be bought by anyone.
The cheaper DSL-AC68U has more features and works better.

I have been using this modem router for almost 2 years and I am disappointed. I wanted to replace our ISP given TG789vac v2 with something decent to use with our NBN (FTTN) connection. Something that could give us better Wi-Fi coverage across our 2 story house. Something that could give us web filtering and protection against WAN to LAN attacks. I thought ASUS AC3100 was the answer to my prayers from up above! Oh God! What a mistake it has been so far! Today, my DSL-AC3100 is working as an access point downstairs with all routing features tur...ned off. Pro: Decent 5GHz band coverage and stable modem. Cons: Pretty much everything else: 1. AiProtection feature slows down internet download times to dial-up speeds. Only Option is to disable AiProtection and use Open DNS for protection. 2. Constant 2.4GHz connection drops outs. I eventually turned 2.4GHz frequency off. ( I can live with this as all our devices at home now use only 5GHz frequency. ) 3. NO AiMesh Support due to hardware limitations according to ASUS. 4. No Adaptive QOS.

The reviewer stated that an incentive was offered for this review
Saw a radical improvement in bandwidth and data transfer rates over my previous Asus AC68U. The DSL AC3100 showed a dramatic improvement in use and its performance. I am only disappointed that its mobile app does not work ss it should.

Worst modem router ever
Absolute garbage. Unreliable wifi. Limited range on wifi. My stock iprimus and 30$ range extender anihalates this 300$ paper weight. Will be onto Asus for a full refund. VERY DISSATISFIED

An unreliable modem cannot recommend this one
After 19 months of generally reliable use, beginning about two months ago the internal power supply began to give intermittent problems with not restarting after a soft reboot, not restarting after power down - power up, and finally not powering up at all, the modem had died. The modem was not as good on NBN as my spare Netcomm NF18ACV in performance, the Asus achieving max of 51 Mbps line sync whilst the Netcomm achieved 57 Mbps line sync.
Below average performance for a premium priced item
The DSL-AC88U has been plagued with problems since I first purchased the item. I'm now on my second unit as the first one completely died (Harvey Norman Toowoomba replaced the unit without question).
Setup is not too bad if you've had previous experience with routers but the GUI could do with a bit more polish. I haven't been able to get the VPN Client to work yet (with PIA - OpenVPN).
Firmware updates are few and far between, which doesn't instil any confidence in the product. I have to reboot the unit several times to establish VDSL sync. Q...oS is fairly basic and hasn't been updated (due to a lack of firmware updates) and the Asus Router App doesn't even support the DSL-AC88U. This product isn't even that old, not even two years (release date Sep 2017) and you can't even use the Asus Router app with it. I've basically given up on this modem/router and placed it in bridge mode (modem only) and I'm using a Synology RT2600ac for routing duties.

Full of issues. Not reliable and too expensive.
I have this router for 10 months and the issues started to appear slowly.
Let's start with the fact that firmware updates barely exist.
The QoS of this router is very basic.
The Asus mobile app doesn't support this router, despite its expensive price.
Memory leaks when trying to use the Ai protection.
USB transfer speeds are terrible.
Major issues with 2.4Ghz wifi and broadcomm chip set. Devices cannot connect to the router, iOS and Android.
This router is too expensive for what it offers. It offers mainly bugs.
I'm so sorry I've switched from Netgear....

Faulty product out of the box
I bought this modem to replace my netgear modem that died after about 5 years of use. Still no nbn in my area so still using adsl2+
After setting up this unit (looks very nice but large), and upgrading firmware, was faulty right from beginning. 5ghz bandwidth wouldn’t allow me to connect with my devices (kept saying incorrect password even though I entered it correctly). Even the 2.4ghz bandwidth was flakey - says connected but doesn’t download data. The only way it worked way was when it connected via lan directly. The wifi was faulty it ap...peared. Temperature of 5ghz was operating constantly over 73degz celcius. Msy was happy for me to return it. Returned it and was out of stock, so decided to downgrade the one lower asus model dsl-68u. Best thing that I did as this modem router was far superior to the most expensive one. And was about $180 less than dsl-ac3100 (88u). Range was awesome compared to my old netgear (which I needed extended previously) and connection been smooth and fast. Havent had the need to restart the modem router. Would not recommend with dsl-ac3100 model.
Perfect when configured properly ....
Had enough with iiNET's freebie modem router ( tg789) and decided to upgrade. TG-789 has many limitations and poor wifi coverage.
We have a large double storey house and wanted something awesome to cover the entire house
and decided to buy ASUS DSL AC3100 having read what it can do. Configuration is a bit fiddly and once configured properly connection is rock solid. Default settings do not work and using the wizard on a FTTN connection is not recommended.
Some users complain about problems with the 2.4Ghz band. Need to change quite a f...

Fast Router with Good Range - Poor Client Cap
This is also known as the Asus DSL-AC3100. This router is fast and works well with a powerful range. However, it is limited to a maximum of 30 clients. This means that it will start dropping clients when this number is reached and you will randomly lose your wifi connection over time. This is a very poor design for such an expensive router as routers 5 years ago were able to handle the same amount of clients.
I also tried the D-Link DSL4320L and hit an even lower cap! Do yourself a favour and buy a Google Wifi router, one of those units can ...easily handle 50+ connections with no drop outs what so ever. They are much cheaper as 3 of them (150+ clients) will cost just under what it will cost for one of these. Poor design ASUS, why can't you upgrade your chipset to get into the modern age of smart home devices? A router needs to be able to handle more than just 30 connections or it is useless.

Apparently broken at present with many long standing customer problems. Limited functionality.
I purchased two of these. One on ebay (now on it's way to the tip) and one from Harvey Norman (returned). For me, both had identical issues;
1) WiFi connections dropped silently every 1-12 hours. Devices (phones, laptops, TV's etc) looked OK and thought they were connected, but could not actually transfer data. I tried multiple firmware versions and a host of different client and router settings, to no avail. Workaround was to reboot router or turn clients' WiFi off and back on again.
2) Compared to other comparable Asus devices with A...SUSWRT firmware (e.g. RT-AC88U), the functionality is cut down. E.g. Limited QoS. No support for; AiMesh, Smart Connect, Traffic Analyzer, Alexa or IFTTT, or Time Machine backups. Many other Australian customers have had ongoing issues. On Whirlpool, there have been 106 PAGES of posts over 18 months from customers trying to get these machines to work (see https://forums.whirlpool.net.au/archive/2606692). Asus have released a number of patches, but the problems still remain. For about the same price of one DSL-AC88U, I replaced them with an Asus RT-AC88U router and a Draytec Vigor130 modem. This combination has been 100% reliable and offer much more ASUSWRT functionality.
Nice router which will probably get even better
I was looking for a new router with support for my new NBN FTTB connection and DSL-AC88U was just released, successor to a great DSL-AC68U router. It does its job reliably, it's currently running for a few months without a single reboot or dropout, holding 100/40 speed perfectly and serving ~10 Wi-Fi devices we have in our household. The only downside is the lack of advanced capabilities its predecessor had (richer QoS capabilities, traffic control by device), but these will probably come with the future firmware updates, ASUS has a good history of supporting their networking hardware and this device is very young.

Very fast Modem with questionable reliability
After 5 units I gave up and got a refund. Asus were very responsive and swapped it over without fuss. When working properly excellent speed and great wifi. It's a big step up in performance from the excellent DSL-AC68U but is missing some key features from its predecessor namely the ability to track bandwidth by client and a few others. I think they will come with updates as Asus is excellent in maintaining its development. This was probably a bleeding edge purchase so I put the first failure down to that. the other failures were all electric...al- usually after a thunderstorm any where in the country... It is quick to setup though in this early firmware is missing a lot of ISP's. It's not for the unskilled at this stage but will be in a few months. I'm on Turnbull's disgrace- NBN FTTN and I have reliability and speeds that make the NBN look good. My ISP (Aussie Broadband) has a lot to do with that - but this modem helps greatly. Its big, its ugly. Its high tech- and its totally unreliable There is no Voip with this unit- I use a separate Linksys PAP2t box for that which is cheap and works fine. However if you are with Optus or Telstra and you want to use Voip you can't- as neither ISP will give you the settings you need to setup on a different device. For most houses this unit has strong enough wifi to cover the entire house.
