I should state that I m probably not as technically knowledgeable as most of the other reviewers. I must even confess that through some inattention on my part I thought I was ordering a router with a wireless access point. When I unpacked it, I was disturbed to find no ports!
I bought it because the performance of my previous 802.11g wireless network was inadequate to support working from home over a VPN. That problem is now solved, but only after substantial effort.
The first problem I had was that after plugging it in I could not access the configuration app. I got on the D-Link website and went through their procedure for fixing the problem. I know I should read the whole procedure before starting it, but impatience got the better of me. I executed the step that caused me to lose all my cookies and internet history before I got to the step that addressed the real problem: the default IP address of the device is on a different subnet from the default used by all six of my computers and my router. I had to change the IP address of one of my computers and of my router in order to change the IP address of the access point and then change back the computer and router to get everybody on the same page.
After configuration, I noticed that my laptop was no longer connecting using 802.11n. It had fallen back to 802.11g. Had to re-establish the default configuration and then step through it again one parameter at a time to discover that adding encryption caused the degradation. No help from D-Link sources on this issue. On Google, however, I found a very good article explaining that 802.11n works only with WPA security using AES encryption. I had blindly used the same WEP security as on my previous network.
Still my 802.11n connection was not operating at the expected speed. I think it was somewhere in the neighborhood of 100 Mbps. Again using Google and getting no help from D-Link sources, I learned that 802.11n can achieve its maximum potential only when broadcasting in the 5 GHz band. I switched to that band and immediately got a bump to 150 Mbps. Of course only one of our five laptops has a 5 GHz radio. Since so far 802.11n is needed only for my work laptop, I decided to leave the old 802.11g wireless router in operation for backward compatibility. The alternative of using only the new D-Link access point would force me to sacrifice some of the performance achievable with 802.11n.
So it all worked out well. Through ignorance I lurched into a superior solution. If I had bought the 802.11n wireless router originally intended, I would not have been able to maximize my 802.11n performance without disconnecting my 2.4 GHz laptops.
I m happy now, but I must fault D-Link for not putting more helpful information in its various instructional materials.

I have a very large house, and I am able to get an excellent signal throughout. In fact, I was able to eliminate several additional access points I needed in remote areas of the house. They are no longer necessary. It would be nice if it were able to transmit in both frequencies at the same time. As designed, you have to pick between 2.4 ghz, which is compatible with Wireless G, and 5ghz, which has better performance in N. Much better range than the D-Link 1522, which I also own. However, it lacks the additional ethernet ports. As with most access points, setup is a pain if your router uses a different address domain. The Dlink interface for entering MAC addresses if you use mac filtering is also pretty clunky. It would be nice if you could block copy all mac addresses from other access points instead of entering each mac address separately. But overall a great product.

This product is the real deal. I experienced over 120 mbps throughput over 5ghz when in the same room (with laptop less than 10 feet away, with all the wireless nic s power settings turned off (Intel 5300 nic)).
This product offers class leading speed, reliability and POE! All for $99! Everything about this w.a.p. is fantastic except for it s QOS setting. When enabled, I experienced huge throughput losses. So, keep the QOS setting turned off on the w.a.p. Also, it s not simultaneous dual band. So if you want both a 2.4ghz and a 5ghz w.a.p. then this is not the unit for you.
If you only care about 5ghz, then look no further as D-link has hit a home run with this product.
