Summary: I only need 802.11n, and the ability for the router to act as primary or secondary, and still have access to the USB devices locally. I have had no issues with the router, LAN, WAN or Wireless. The setup was easy and it has extensive documentation. It runs cool, and USB devices don't get real hot, like they do on Asus router USB ports. The software to use the USB ports didn't work until I found an updated version for Win 8.
Summary: Works way better than the previous ZyXel, which was limited. This model router has a stronger strength which translates into better connections. Transferring from on model to this newer model was easy.
Summary: We have used the standard version for quite some time so we were apprehensive about the V2 (Version 2)- so far we have used three of these and they are working quite well, the new software has many features you only find in expensive units. We install Wifi in Commercial and residential settings as well as outdoors. The NBG4615 continue to deliverer reliable service for a great price point. We did like the White ones V1, but after a few years they yellow.
Summary: Decided to recycle old Linksys WRT54GS2 for more current hardware supposedly compatible with Comcast system ugrades...Big mistake! Not only did this waste my money, but over three days of my time trying to get this ZYXEL router to recognize it's own ZYXEL cable modem plugged into WAN port (purchased several weeks ago). -Never even got to the wireless part- What a poor excuse for "high tech". That old Linksys I bought used for $30 is looking pretty good now.
Summary: This is 3 months old. Had my IP address change because of new modem and this would not recognize it at all. After 3 modem and router and computer restarts and 2 hours total on the phone with their customer service and my internet provider. My internet provider offered more help then their CS did. Followed the reset procedures from ZyXEL web site[their CS didn't suggest this, i did it on my own] and it made my computer crash twice. My computer has NEVER crashed before.
Summary: it is working like a charm, i wish it had more ports, it so nice i love the password option and the option to turn off the wireless so those freeloader wont slow down the internet by logging on with fones, laptops and tablets.
Summary: This device has all the options you need to set up your network to what you need. It also has great monitoring tools on it. Wireless strength is fantastic. I have this setup in a building using wireless through framed walls and brick walls with no problem. I would highly recommend this product to anyone needing to setup their wireless network.
