Introduction

D-Link DAP-2553 AirPremier N Dual Band PoE Access Point

At a Glance
Product D-Link AirPremier N Dual Band PoE Access Point (DAP-2553)
Summary Dual-band, single radio 802.11n business AP /Bridge /Client based on Atheros silicon
Pros • Dual-band
• Can be used as AP, WDS bridge or client
• Can be powered by power wart or 802.3af PoE
• External, upgradeable antennas
Cons • Single radio, so no simultaneous dual-band.
• No WPS support
• Won't extend your 5 GHz range vs. cheaper products

Given the interest that the DAP-1522 garnered as an 802.11n bridge, I asked D-Link to send its business-grade DAP-2553 for review...quite some time ago, in fact. The delay in review is all my fault, so my apologies to D-Link up front for the time it's taken me to get to it.

A lot of 802.11n water has flowed under the Wi-Fi bridge since I looked at the DAP-1522 back in mid-2008. Back then, the 1522 was the cheapest way to add 5 GHz band 11n coverage to an existing LAN.

But now, dual-band APs are very common and you can even pick up a single-radio DIR-628 refurb for under $50, as I write this. However, price isn't the 2553's main claim to fame, but business features like VLAN and 802.3af PoE are.

Figure 1 shows the 2553's back panel, which contains a single 10/100/1000 Ethernet port, reset button and power socket. The three dual-band antennas are connected via RP-SMA jacks, so can be upgraded if you so wish.

The front panel is pretty simple, with just indicators for power, 5 GHz, 2.4 GHz (to indicated radio mode) and LAN Link / Activity. The 5 and 2.4 GHz lights just blink at a steady 1 second rate and provide no indication of actual wireless traffic.

Note that there is no mode indicator to show whether the 2553 is functioning as an AP, WDS bridge, WDS bridge / repeater or wireless client. There is also no button to kick off a WPS push-button session, since the 2553 doesn't support WPS, nor a mode switch to manually set AP, Bridge, Repeater or Client mode.

Internal Details

Figure 2 shows the rather fuzzy FCC ID photo, which is clear enough to show the Atheros devices that power it. Fortunately, the internal pictures file had close-ups of the key devices, which are an Atheros AR9132 802.11n 400 MHz Wireless Network Processing Unit (WNPU) and AR9106 Dual-band 3x3 MIMO 802.11n radio.

There was no close-up of the Gigabit Ethernet device, but I'm guessing it's an Atheros AR8121. 16 MB of Spansion flash rounds out the design.

Features

Initial setup was a bit annoying since the 2553 comes set to a fixed 192.168.0.50 IP, which doesn't lie within my LAN's range, instead of grabbing a LAN-compatible IP via DHCP. But after a quick change of my computer's IP address to the 2553's subnet, I was able to log into the admin interface, which isn't password-protected by default.

I'm not going to tour you through the 2553's interface, since D-Link conveniently has an online emulator of the 2553's complete admin GUI. Instead, I'll just summarize the 2553's key features bullet-style:

  • WEP and Personal / Enterprise WPA / WPA2 wireless security
  • Wireless Modes
    2.4 GHz: Mixed 802.11n, 802.11g and 802.11b; Mixed 802.11g and 802.11b; 802.11n only
    5 GHz: Mixed 802.11n, 802.11a; 802.11a only; 802.11n only
  • MAC address filtering
  • 802.3af Power over Ethernet support
  • Tranmit power control (100, 50, 25, 12.5%)
  • Transmit data rate (but limited, see below)
  • Client connection limit (0-64, 20 default)
  • Up to four SSIDs, each with separate wireless security
  • Up to four VLANS w/ 802.1q tagging
  • "Rogue" AP scan
  • Wireless access enable / disable schedule
  • Four level priority-based QoS
  • DHCP server with IP reservaton
  • Telnet, SSH, SNMP, HTTP, HTTPS admin interfaces
  • Client-to-client and client-to-wired-LAN partitioning
  • Ethernet and WLAN statistics
  • Logging

The feature set provides a bit more than your average consumer wireless router and makes for a relatively full-featured AP. Emailed alerts, to go along with the "rogue" AP scan (D-Link calls this feature "Intrusion Dection, which is really isn't), and log / statistics summaries would have been nice.

As noted earlier, Wi-Fi Protected Setup (WPS) isn't supported, since it's not used in the business environment that the 2553 is intended for. The Transmit Data Rate control was only available when a mode that included 11n wasn't selected.

I didn't try the WDS bridging features of the 2553, but did try Wireless Client mode. Figure 3 shows that you need to select a band before you scan. So you'd better assign both the wired device and the 2553, static IPs in your LAN's subnet, but outside your LAN's DHCP server, so that the two can communicate. Once you get connected, which isn't obvious from the Wireless Settings page by the way, you can change your client to use DHCP so that it gets proper gateway and DNS settings.

Actually, the way I initially tried this was to keep the 2553 attached to my LAN's switch while I set it to client mode and scanned. Once it picked up my LAN's wireless AP, I selected it, entered the WPA2 passphrase and waited. Once I saw all the LEDs on my LAN switch start blinking madly—due to the network storm caused by the switch port-to-port connection made by the new wireless connection—I knew that the 2553 had connected.

I inherited one of these at my new work place, and one of the first things I noticed when I jumped on it was that the network printer I had added while connected to Ethernet no longer worked after connecting it to the wireless.

It seems everyone there has run into this problem, and worked around it by just adding the printer by specifying the IP manually. This works, but is unideal for many reasons.

It turns out this AP does not properly broadcast/multicast as required by zeroconf. It is unfortunate that a higher-end AP would not properly implement a standard, and I will likely be replacing this AP with something that does.

These devices are great. I have two of them you can group them as a single device. So if you configure the master it automatically get replicated to the slave. No need to make changes twice, mistype and all that.
It is very stable and very fast (firmware 1.21). In the future I may break the grouping so one can be on 5 GHz and 2.4 GHz. I am using a PoE on Gigabit ports. The device I’m using is At-6101g (Great also).

I would highly recommend both.
I have had these for about 1 year.

When I first saw the reviews here I thought I'd give one last try to D-Link's products. In the past I didn't have much luck with other routers and modems but this time, all I have to say is that D-Link managed to make an excellent, business class product.

The range is one of the best features I've experienced so far since I have a similar setup as the Location E used in the reviews around here. Another can't-live-without-it thing is the ability for multiple SSIDs for visitors. Saves a lot of trouble for setting stuff.

The only thing I didn't like is the ability to have 2.4 and 5 Ghz at the same time in a dual mode setup but, since my main concern is with the range and throughput, the 2.4 has so far been very reliable and problem free.

I have owned this guy for 6 months so far and I never had to reset it ever since I bought it.

Highly recommended.

I really like this unit as well.
Just had to say that it can use POE an Gigabit at the same time. Mine is connected as I write this. You must use the correct type of POE unit. Either a decent POE switch or a Gigabit capable power injector.

What do I need to really say, it works and has not failed me yet. Two set backs, first is that the Ethernet port is gigabyte, but when running POE max is 100 megabit (not DLINK fualt as most POE devices are this way). Second is that it will only run either 2.4 or 5ghz at one time, I would love to get another one to have running on 5ghz for media. I have the unit in the basement and it covers the entire house with no problems. Having the capability of having multiple SSID's for when I have a few friends over I can give them access without compromising my keys.
