Connectivity is superb, we avoided the fiasco that is the NBN and went with Optus 4G
Dropouts are very, very rare.
Management ranges from simple to complex, I have 2 mesh repeaters and wanted to flood the house with signal.

After deciding that my old trusty Netgear router was struggling with all my devices, I thought I'd upgrade to the Asus ac88u. Got the router and it was great for about 15 minutes. I tried all the settings and factory reset it a few times but after 2 days it completely failed. I got a replacement and it seems to last about 20 minutes before dropping out. This is officially the worst product I have ever purchased.

I recently purchased the ASUS RT-AC88U Dual Band AC3100 Gigabit Router I have found this product to be perfect for my needs it offers gigabit wired networking and fantastic other features like being able to have a hard drive connected to be able to do mac back up It also is grate for gaming and has a feature to speed up the connection for gaming networks it is fairly easy to set up and if you do run into problems there are plenty of YouTube videos from asus and others that will walk you through the setup highly recommend this product

How satisfied are you with the connectivity of the modem/router to your devices?
very good.

How often do you get dropouts that are fixed by resetting the modem / router (ie. the ISP is not at fault)?
None that ive noticed.

How difficult is it to set up and manage this modem / router?
pretty easy if you have a bit of background knowledge i use the ISP modem as a bridge.

Ton of features and great range. I haven't had a single drop out or Reboot needed since switching from a Dlink taipan. It also just smashes the d'link in feature set and range. The extra LAN ports is also great for homes with a fair bit of Ethernet wiring.

Not the prettiest thing but I don't care as long as it works. That said, their customer support pages are terrible so I hope I don't have to use them.

This router performs very reliably and has no trouble at all downloading at 50mbps on NBN, or streaming or file sharing between the 7 other devices on my network. I installed the Merlin custom firmware for some extra features, but it really has everything most users would need with the stock firmware, including the VPN client functionality which is so convenient. The speed and range are excellent on both the 2.4GHz and 5GHz bands. I really don't think you can go wrong with this router.

I've had a great experience with the AC68U I had high hopes for the AC3200. I've read a few things about sketchy setup issues and dropped connections so was a little nervous. Anyway, I followed the directions to first set it up and immediately download the latest firmware. First note is that I did the quick setup and that worked great. It prompted for the firmware upgrade and I did it. After doing it, I reset configuration back to factory default using the Web GUI. This ensures settings with the latest firmware are addressed in the config file. I've had stable connection and I've seen a performance improvement over the AC68U. For a single router system I highly recommended it.

This router is awesome. No connection drops and a great range. Bonus is that it has a futuristic love it or hate it design, and I absolutely love it. Sad thing is that it does not have an inbuilt modem, wherein I still have to use Optus’ Junkbox to connect with NBN. Beside this, the product is highly recommended

3 stars as it was a great unit while it worked, but...
1st RT-AC88U lasted ~6 months before dropping the 5Gwifi band permanently. Factory reset and rescue mode was unsuccessful. Returned to reseller.
2nd RT-AC88U lasted 4 hours before dropping the 2.4Gwifi band permanently. Factory reset and rescue mode was unsuccessful. Returned to reseller.
We have swapped to a RT-AC68U which looks to be a more reliable unit, only time will tell.

I have been using the router for a while and I can not fault it. The Wi-Fi range is great yet no outstanding. I installed Merlin on it and it runs with no complaints. The software comes with a bunuch of very useful features (not only for geeks). If I had to purchase it again I would not think twice.

I am using this router on my 100/40 NBN connection. It's wifi coverage and performance is great. It also has a lot of security features that most family needs. For more demanding user, there is also custom firmware available which makes the router even more flexible.

I only give 4 starts because the router seems to slow down the connection over a number of days. I am hoping that the latest firmware fixes this.

Potentially very good router spoilt by poor ASUS technical support and unreliable connectivity issues. Needed regular (couple of times a day) reboot prior to connecting to its printer server and other devices e.g. Chromecast, for these devices to be recognised and operate correctly. Replacement with a new A6 hardware revision and latest firmware failed to fix the issues. After replacing with a TP Link router, the regular reboots were no longer needed.
