Excellent DSL modem
Searched and searched for a new ADSL2+ modem that had good IPv6 support (or any for that matter). Some said they did, but did not. Bought and returned a half a dozen from various sources before I came upon this one from Zyxel. Was very happy with their modems on my BBS back in the day and this one said it supported IPv6, so I got it.
The firmware on it had nothing in it about IPv6. Contacted Zyxel support and they immediately sent me a link to an updated firmware - installed it and the IPv6 support is there. Very easy to setup and run and working flawlessly with my 12 meg CenturyLink DSL - dual stack.
Highly recommend this DSL modem - best out there IMNTBHO and the price is better than most of the competition.

[edited] No support for firmware from manufacturer
edit: actually, they do have it, and I found it: [...] No support for firmware from manufacturer, I mean the firmware updates are actually in their FTP servers, but they do not provide a link or description.

Great "Professional Level" DSL Modem
This is a great "Professional Grade" DSL modem. I say that because this is the model that my local phone company provides for their DSL service. (I intend to replace the phone co. provided unit, and avoid the monthly charge).
This unit is extremely sophisticated and highly configurable (as you would expect for ISP provided equipment). The sophisticated nature of this device, and the fact that a phone co. ISP would choose it as their "standard" would seem to vouch for it as "professional grade" equipment.

Purchased this gateway to replace my Actiontec 300 Mbps Wireless-N DSL Modem Router (GT784WN) which developed daily periods of flakiness where my DSL speed would drop from 12Mbit to 1Mbit for a few hours every evening.
I selected the ZyXEL because it was supposed to be more enterprise grade, used by many ISPs, etc, so I thought it would be more reliable. Wrong!
It seems that most combo ADSL modem/Wireless routers are just poorly built and frequently overheat, drop connection, or get slow, and the ZyXEL is no exception to this. After owning it for about 4 months, I found out it developed a new symptom. The speed is not the issue any more. The problem is keeping a connection open. All connections get severed after about 3-5 minutes. If you're trying to download a large file, forget it. (Hope your file transfer client supports auto reconnecting from the last received sector.) If you're trying to stream video from a SlingBox, be prepared to have to reconnect every 5 minutes. AWFUL!!!
I tried enabling logging on the device and there aren't any errors that stand out, only a warning message that the CPU load on the device is constantly over 90%. So I suspect that it is also overheating and just giving up.
So in the end I have to dump this modem too. I just wish I could pay $150 and get a great modem rather than buy 3 $50 ones that suck. I am trying UPVEL UR-344AN4G+ next. Looks to be a new model that doesn't overheat.

not worth it...
We purchased this model for the following specs: IvP6 compatible, ADSL2+ compliant, and wireless. Setting up a wired connection was relatively painless, but setting up wireless was a 4hour nightmare I wouldn't wish on anyone. We had several calls in to our ISP and to Zyxel for troubleshooting. Hint: you have to turn on "flashy green light" prior to initiating a wireless connection, but turn OFF "flashy green light" before you actually click "connect to wifi network" on your device. A day later,the Zyxel died. Am sending back to AlumiGogo and going with a Netgear r6300 + a TP-link TD-8817. Save yourself some frustration and don't purchase this modem!

Not a good idea for AT&T
I ordered this because I have two of their WAP3205 network bridges. They work so sell I thought this would be a good choice, but it came to be overwhelming to try to get it going with AT&T so I returned it. The bridges were a bit of a challenge, but one reviewer has all the steps lined up and they both work well.

50% Idle RAM usage, Memory Leak, Low RAM capacity
Before you continue, yes this is updated to the most recent firmware.
My ISP gives these out and let me tell you something nobody else it.
When you first start this up (and i mean every time you lose connection and you unplug it and plug it back in, no just the FIRST TIME)
it idles at using 50% of it's RAM. I see no way to know exactly how MUCH RAM it has, but you can expect to have to unplug this about every 5 days, because it has a memory leak. It uses all of it's RAM and then freezes forcing you to shut it down.
Kinda sucks when I'm trying to Remote into my home machines.
I will say this though. It has a sleek Web interface and it can Port Forward! It works well when it works too! It just needs more RAM and for someone to fix the memory leak.
