Wireless AC1200 Dual Band Access Point

The DAP-1665 Wireless AC1200 Dual Band Access Point is a fast and versatile solution for bringing wireless AC to an existing wired network, or extending the capabilities of an existing wireless network. The latest 802.11ac technology delivers combined speeds of up to 1200Mbps, creating a high-speed wireless link between networks for optimized performance and reliable coverage delivering high-quality HD video streaming, gaming and file transfers.

High-Speed Wireless and Wired LAN

The DAP-1665 features the latest 802.11ac wireless technology, capable of delivering combined speeds of up to 1200Mbps over two bands. Use the 2.4GHz band's 300Mbps for web surfing, email and chat, while simultaneously using the lower-interference 5GHz band's 867Mbps for network bridging, downloading, video streaming, and file transfers. For wired connections, the Gigabit LAN port enables wired data speeds of up to 1000Mbps – meaning that Gigabit-compatible wired devices can also benefit from the high speeds of wireless AC.

Versatile Operation Modes

The DAP-1665 can be configured to operate in several modes. Access Point mode allows the device to act as a central hub for wireless users, giving them access to an existing wired network. Bridge-mode creates a high-speed wireless link between two wired networks (LANs), alleviating the need to install additional network cabling. Repeater mode extends wireless coverage of an existing wireless network to cover "dead" spots and reach farther into a business environment. Bridge mode with AP adds the functionality of a wireless access point to a bridged network, so wireless clients can access resources on both networks. Wireless Client mode is available to enable the DAP-1665 to connect to another access point and provide network and Internet access to a remote wired device such as a gaming console or media center.

2 out of 5 eggsReally NOT very good

Pros: Easy Setup

Cons: Very poor range and low bandwidth. When first installed I got 45Mb anywhere in the house. Now it only covers half the house and won't go above 1.5Mb. I've always had good luck with D-Link in the past but this unit is a turkey.

5 out of 5 eggsWorks fairly well for the price

Pros: Cheaper than most APs that I have seen and works fairly well
Great for adding wireless AC to your home network without having to buy a new router, plus easy to setup and use.

Cons: Wireless AC speeds are slower than they should be but I manage to get about 300mbps out of it. Range is also not that great, get about 60 ft range out of it before your signal quality drops by half.

Other Thoughts: Even though the speeds are not top notch on this unit if you live in an apartment building with alot of people using wifi its a great way of running your stuff on a completely seperate frequency range and to not have as much interference.

4 out of 5 eggsSmall Area Extender

Pros: Repeater or Bridge, works well for both.

Cons: Range is not as far as marked on the box in real world conditions.

Other Thoughts: Bought 2 of these to use in bridge mode across a 150 ft gap. Unfortunately they couldn't do it. If you have interference like competing wifi signals or large structures, the range is severely limited. They do a great job under that limitation.

3 out of 5 eggsDecent AP; range sucks

Pros: The AP was very easy to setup. The .local does work so you don't have to figure out what IP it obtained. Very simple GUI; liked that. Not the least -- the AP does look cute; white plastic with rabbit ears antennas. Not the least is the fact that this is a dual band 2.4GHz and 5GHz AP. Now onto the speed -- compared to my older Linksys 2.4GHz only AP I get about 50% more bandwidth with this one. Excellent!

Cons: Range is really bad; both bands that is. I am comparing it with older Linksys 2.4GHz only AP and on that band I got much better coverage in terms of distance. Obviously we are talking the same physical setting -- same house and location of the AP.

Other Thoughts: This AP gets what you would expect in terms of speed. My older Linksys 2.4GHz only AP was terrible so I am a happy customer all said and done. Range does lack but at this point I like the speed better than roaming around the house with my devices. It is a thing about priority over one feature or the other.

3 out of 5 eggsGreat until it's not!

Pros: Very easy setup, extreme speed, reasonable cost. That's three of the four things I want in a wireless device.

The 5Ghz band doesn't have as much range as 2.4 but it's pretty good.

Cons: Unfortunately, the fourth thing I want is reliability and it's not there. I bought two of these and tested one at home and the other at the office. Both of them work great for a few days, then start randomly dropping connections. Logs look like it rebooted though the front panel lights never did anything. It will continue like this, dropping connection and clearing logs every few minutes until you physically remove power from it. Plug it back in and you're good for another day or two - and repeat.

Other Thoughts: I installed the newest firmware and did factory reset before trying anything else.

4 out of 5 eggsSo Far So Good

Pros: Easy setup, very reliable. Had no issues setting up and installing. I have this mounted on the wall, it blends in nicely without obnoxious blinking LEDs.

Cons: As others have noted, the 5Ghz range isn't very good. I have this in a sub 1000sq ft NYC apartment with plaster walls. Signal strength is greatly reduced two walls away.

Other Thoughts: Would recommend this to others, for an AC access point at this price point there is not much to complain about.

4 out of 5 eggsGood AP

Pros: Nice Range, nice interface (very similar to other DLink products I have), and feature rich. Devices connected with no problem, using the same SSID on both bands worked with no problems and everything connects at the fastest speed possible.

Cons: I don't like the inactivity auto logoff timer, *save often*. having only 20 MAC addresses for white listing is short in today's world of "everything is connected".

Manufacturer Response:

We wish to thank you for your feedback as we do value and appreciate it very much. We have been advised by our Product Management team that there is a current work in progress on a new upgraded firmware that will soon be released and available that will expand the current available MAC address listing from the current 20 now available to a maximum of 60 MAC addresses. We appreciate your patience during this development process and request that you continue to monitor for the next firmware release for this Product. Thank you for choosing D-Link.

1 out of 5 eggsMaximum User Capacity

Pros: Solid device with good basic config settings. Good connectivity throughout client devices.

Cons: This unit and doc says the user limit of 1~32, BUT ONLY up to 20 MAC addresses for Mac Filtering under Advanced setting. The manufacturer SHOULD document the unit's limitations in terms of its capacity. How could I enable MAC address filtering to only allow, when I have more than 20 devices, (more like 40+ devices) in and out throughout the day???????
I would NOT have purchased this unit, had I known this limitation. Nowhere in the documentation...

Other Thoughts: Considering a RMA or whatever to return...

Manufacturer Response:

We want to thank you for the feedback as we greatly appreciate the input and we are sorry to hear that you are dissatisfied with your purchase. We will pass on the information you have provided to our product management team for consideration. To request an RMA give us a call at 1-877-453-5465. We thank you for choosing D-Link.

4 out of 5 eggsGood entry-level 801.11ac access point

Pros: 802.11ac support; theoretical maximum of 867 Mbits/s on 5GHz band; easy setup; on/off switch; good price.

Cons: Range on 5GHz band could be better; plastic case.

Other Thoughts: I'm using this with a Verizon-supplied Actiontec router with the router's WiFi radio disabled. Setup was trivial. Speed is quite adequate for my FiOS Internet connection; though I only have one 802.11ac client on the network and can't really test the internal network speed there.

My only significant complaint so far is that the range of the 5GHz radio leaves a bit to be desired. It's adequate sitting on the second floor of my 3-story townhouse; but if you want to fill a much bigger space, you'll probably want a repeater (for which you could use an additional DAP-1665, though I haven't tried that).

A metal case would have been nice; and the power switch feels a little flimsy. It's certainly not the fastest that 802.11ac has to offer; but the price is right on this unit; and at the moment there aren't too many other home/small office 802.11ac access points on the market.

5 out of 5 eggsWorks well on day 1

Pros: Works well with my DLink DIR-860L router (I'm using the router in wired only mode). The 802.11ac mode is a nice speed improvement for my devices that have ac. I have Comcast internet- and IPv6 is supported on the 1665. With this WAP, I'm now using IPv6 on all my WiFi client devices- they pass the Comcast IPv6 Readiness Tests.

Cons: none so far
