2 out of 5 eggsVery easy to set up

This review is from: D-Link DIR-855L Wireless N900 Simultaneous Dual-Band Gigabit Router w/ SmartBeam Technology IEEE 802.11a/b/g/n, IEEE 802.3/3u/3ab

Pros: Looks impressive - some people will love such design.
Very easy to get internet operational. Almost plug and play.
Fast LAN ports. So fast, that my computer's HDD became a bottleneck when copying a large file to it.

Cons: A mediocre coverage, both on 2.4 and 5 GHz. I am surprised that other people praised this router for a good coverage. Forget about HD video or transer of large files over Wi-Fi.
The firmware is unhandy to use; slow responding (many other routers are the same), with some features lacking (only three settings for power: high, medium, and low), no chance to set DD-WRT or Tomato. In addition to all, it requires restart after making any change (each takes between 60-120 sec).
The cloud service requires registration on D-Link website. Tested it for several hours (with HDD attached): slow and clumsy, compared with what I've experienced with routers from other companies.

Other Thoughts: I have plenty of people in surrounding area who use 2.4 GHz networks, so this may explain a bad coverage. Nobody around me uses 5 GHz so far, but the signal droped below -70 dB in 3-4 meters withing the same living room (with link speed at 14 Mbps). This is what I cannot understand.
Overall, this router makes an overall bad impression. I would expect to get a decent router for this price.

1 out of 5 eggsCool looking disappointment

This review is from: D-Link DIR-855L Wireless N900 Simultaneous Dual-Band Gigabit Router w/ SmartBeam Technology IEEE 802.11a/b/g/n, IEEE 802.3/3u/3ab

Pros: It is definitely a nice-looking unit with a great set of cool features.

Cons: Performs very poorly. Leaving the wi-fi aside, the machine has problems even with routing the local Ethernet traffic. There are lost packages and temporary slowdowns even between the internal gigabit Ethernet ports in the local network! The DHCP is much slower then in other routers, to the points that some devices report time out, before even getting the IP address (even on LAN!). Machines wired to the router sporadically loose network connection for unknown reasons and rebooting the router solves the problem only for a while. Configuring this machine is a total headache. After changing any of the options the router needs to be rebooted which take over a minute. Now imagine adding 30 mac addresses to the filtering table, and you are talking about a 45 minutes job. Note that the mac filtering is done for Ethernet and WIFi so you have to add even the mac addresses of machines directly wired to the router. I spent around two hours for the full configuration, so be patient if you plan to do anything going beyond a basic setup. The unit does not have standard front lights indicating status of its Ethernet ports so you never know what is really going on.

Other Thoughts: Total disaster. If you need something really working forget about this unit and consider Asus RT-NI6 (if you don't need the 5.4GHz WiFi)

Manufacturer Response:

5 out of 5 eggs

This review is from: D-Link DIR-855L Wireless N900 Simultaneous Dual-Band Gigabit Router w/ SmartBeam Technology IEEE 802.11a/b/g/n, IEEE 802.3/3u/3ab

Pros: did give me concern whether this would work in a slot other than an x2 PCIe. Put in my x4 slot and downloaded an updated driver and I was off. This card sped up my backup time, eliminating hours off the actual time. I was transferring about 2-3 TB of data from 2 main SATA 3 HDDs to two SATA 3 HDDs with the main 2 in 6G mode and other two in 3G mode. Big bottleneck. This card removed the bottleneck and was pushing speeds of 100MBPS+ compared to about 10-15 MBPS.

Cons: none

4 out of 5 eggsUPDATE! Improved Performance

This review is from: D-Link DIR-855L Wireless N900 Simultaneous Dual-Band Gigabit Router w/ SmartBeam Technology IEEE 802.11a/b/g/n, IEEE 802.3/3u/3ab

Pros: Design, size, features.

Cons: Read below:

Other Thoughts: I originally posted subpar results compared to my expectations; however, I have seen significant boosts in speed over the past two weeks, specifically on the 5GHz channel. I am uncertain as to the reasoning for the increased performance, but I am grateful. I have changed nothing in regards to my set up or location of the router.

My 5GHz channel reaches into my living room, which is about 60-70ft from the base station and separated by 4 walls. I easily reach max speeds for my connection, 12-13Mbps down, and 1.5Mbps up.

As for the 2.4GHz channel, I have better overall coverage, but I have noticed my phone, iPhone 5s, seems to drop the wireless signal frequently at the opposite end of the house, resulting in the -1 egg.

All in all, I am much more pleased with the router after a month of ownership, and have decided to finally sell off old faithful, my DLINK DIR-655.

3 out of 5 eggsTheoretically great.

This review is from: D-Link DIR-855L Wireless N900 Simultaneous Dual-Band Gigabit Router w/ SmartBeam Technology IEEE 802.11a/b/g/n, IEEE 802.3/3u/3ab

Pros: There's no point in reiterating the specs as pros; I'm sure you've seen them by now.

After two weeks of use, I have had stable connections with no drops; not once did I have to reboot as others mentioned previously.

Cons: This SmartBeam doesn't appear to work one bit, pun intended, in my 1974, 1800sqft, brick home. I had really high hopes for this feature, and am sorely disappointed. Walking from room-to-room and outside I saw severe drops in connection speed.

Compared to my older DIR-655, the range of this unit is comparable. I had both routers hooked up in the front corner room of my house and both units reached the same distance with roughly the same .45Mbps speed - not even fast enough to stream Spotify without buffering issues. Those speeds were recorded while outside opposite side of the house about 100ft difference with an exterior door and 4 walls in between. I truly expected better speeds from the DIR-855, but it was not to be.

The DIR-855 was in line in every way as compared to my older DIR-655; truly, the only difference being that I have a simultaneous 5GHz channel on the newer 855. Of course, the 5GHz's reach is far less than the 2.4GHz; higher frequencies do not travel as far as lower frequencies due to attenuation.

All in all, I was very "meh" in regards to the performance. In my environment, I did not see any great advantage over my older 655, which I strongly recommend. YMMV.

Other Thoughts: If you can find this router for around half the MSRP, I'd say go for it.

However, most people would be better off with a simple wireless-n router and some powerline adapters, which has been my setup for about 4 years. You could also just drop some CAT5 through the walls wherever you need it.

5 out of 5 eggsVery pleased

This review is from: D-Link DIR-855L Wireless N900 Simultaneous Dual-Band Gigabit Router w/ SmartBeam Technology IEEE 802.11a/b/g/n, IEEE 802.3/3u/3ab

Pros: The product was shipped and packaged securely and had all the required items needed to get going, including, router, power chord and start up manual.

Looks. The router looks great and would not be an eyesore in any room.

The router was very easy to setup and was recognized right away by all computers and wireless devices on the network.

I had to watch a couple quick tutorials on how to get to the correct screens in the admin panel to change the passwords, but really it was very simple.

The videos I watched introduced me to the cloud, which look to be a great option for people wishing to access their router remotely.

RANGE! I love the wireless range on this router. In comparing the last 3 routers I have owned this router by far has the best range. The router is in the basement and even with that outside the house I am able to get 3 bars on my cell. Walking away from the house roughly 200 yards I am still able to get a connection. Very happy with this!

I have not had any disconnects while using the router. Its solid.

The price point seems very reasonable for the quality you get in this router.

Cons: I have no cons.

Other Thoughts: Accessing the USB storage device was a bit difficult, but it was able to be locked with a password and now knowing how to get to it, Its not so difficult anymore.

Great Router!

5 out of 5 eggsGreat Wireless Range and Speed

This review is from: D-Link DIR-855L Wireless N900 Simultaneous Dual-Band Gigabit Router w/ SmartBeam Technology IEEE 802.11a/b/g/n, IEEE 802.3/3u/3ab

Pros: I have disabled DHCP and I’m ignoring most of the routing capabilities and I’m using this router as a WiFi access point. The wireless connectivity and range is better than the Apple Airport Extreme that it is replacing.

Devices connected to this router:
• iPhone 5
• Nexus 4
• MacBook Air 2011
• MacBook Air 2012
• HP ProBook
• iPad 4
• Nexus 7
• 2 Xbox 360s
• 3 PS3s
• Dell Desktop
• Custom Desktop
• iPhone 4S
• Dell Inspiron Laptop

They all connect without any problem and do not disconnect until they go beyond this router's great range.

Cons: Even the smallest configuration change requires a minute long reboot. This is kind of annoying, although not a dealbreaker.

There are no LEDs for the ethernet ports to either indicate connectivity or speed.

Other Thoughts: Let me start out by saying that I have Verizon FiOS. The FiOS modem has a built in router. I attempted to turn off all of its routing functionality and pass all traffic through to this D-Link router with little success. The D-Link is not to blame, it is a limitation of the FiOS modem/router. The FiOS router has terribly slow WiFi, so I am using this D-Link router as a WiFi access point.

4 out of 5 eggsGlad to be back with a D-Link

This review is from: D-Link DIR-855L Wireless N900 Simultaneous Dual-Band Gigabit Router w/ SmartBeam Technology IEEE 802.11a/b/g/n, IEEE 802.3/3u/3ab

Pros: Sleek, cool circular shape.
Minimal space needed.
Easy connections.
GIGABIT PORTS.
Nice range on both 2.4 and 5 GHz bands.
Small footprint.
Easy and quick setup.
Extremely intuitive firmware/software interface (made by 3rd party as stated by D-Link).
Has 2 spots where it tells you basic setup and passwords along with a 3rd sticker.
Guest Access.
Dynamic DNS.
Plethora of control options.
Helpful HELP Menu built into firmware that tells you everything each setting does.
Fast speeds on both bands.
Traffic shaping/Stream boost like (yes really)
Smart Beam to better hone signal to wireless devices.
Interference from any other devices or appliances have negligible effects.
USB Port for sharing a printer wireless or NAS device.

Cons: No wall mount option (yes I like to mount mine on the wall for convenience).
1 USB port (2.0)
WPS
No Wireless on/off button.
Bright Power and Internet Light.
Fingerprints
Reset pin hole on the bottom of the device

Other Thoughts: This is a very good router especially for the price so the price to performance ration is very high. It has an intuitive firmware interface for the router and makes easy and advanced options easy to use and learn about. The built in help menu is extremely helpful even for an advanced pro like myself who has taken networking classes. It is helpful to have a reminder for everything the settings do and even for those things I do not recall. The QoS menu is more advanced than the Netgear R6100 I just Eggxpert tested and a bit more options such as Dynamin DNS support for more options. Also, the 5GHz band, compared to the R 6100, doesn't drop out and reconnect sporadically and stays strong throughout the house and even outside. Recognized my Galaxy S4, 5 laptops, Dish Hopper and DVR receivers, and even an older laptop that uses Wireless B (I know it says its compatible but usually I have fits with old tech). You may get annoyed at first with the setup because it doesn't always automatically recognize your Internet setup. I installed this router at 3 different locations with 1 DSL and 2 Cable ISP setups and all three times I had to set the settings manually. It isn't a deal breaker but the preferred setup method by D-Link may not be the best way to go (following the instruction book) I did experience a little bit of a hiccup with the initial settings of the router and had to make a manual adjustment to the IP Routing table but that is something more on my end. I also noticed that each time you make a change in the router you have to reboot it by means of the software (nothing too much out of the way just that it always does it no matter what so it is a bit of a hassle). Finally, this thing is really smart with its Smart Beam Technology. No matter where I go in the house it sees everything at 70% or more on both bands. If I go outside I still get about a 35-57% signal capacity through a vinyl siding house about 50 feet away. This theoretically is a bit unusual for the 5.0GHz spectrum from what I know but I will take it.

3 out of 5 eggsDecent router that looks very nice and works fine with some quirks

This review is from: D-Link DIR-855L Wireless N900 Simultaneous Dual-Band Gigabit Router w/ SmartBeam Technology IEEE 802.11a/b/g/n, IEEE 802.3/3u/3ab

Pros: The router is a Piano black cylindrical device with a high WAF, which is a very good Applesque design and can be a conversation starter. The router also does not get too hot and remains slightly warm when operational.

The WAN / internet LED is a smart light in the sense that it senses an actual connection to the Internet and not just a cabled plugged into an ethernet port.

The router web interface seemed to have an inactivity logout timer which is a good thing if the window is left on by mistake on a shared computer.

All the clients TCP / UDP sessions are visible under the Internet Sessions menu of the router and is helpful for debugging and security audits.

With QoS enabled and with a simultaneous continuous upload session to my cloud server, latency increased just a bit to 17ns and download speeds remained at 10Mbps.

Cons: A minor irritation of this router is that almost all modifications require a lengthy reboot session of the order of 40 - 60 secs. Sometimes the router would not behave as intended after reboot and would drop connections and would have to be reboot once more.

For some unknown reason one of my mbp shows up as 802.11a device @ 243Mbps in the Wifi status page, when infact I had setup the 5GHz Wifi Access Point to work only as 802.11n.

In the WPS menu with PIN option there is a typo and "within is printed as winth"

With automatic upload speed detection, WiFi security is not enabled immediately at bootup and some clients can connect to the router at that time without WPA / WEP. Security is enabled after a minute or so and the clients then disconnect and reconnect, which could be an annoyance and a minor security issue.

WiFi allows guest SSID, but bandwidth control is not available for guest SSID.

QoS automatic bandwidth calculation did not work well. It calculated my upload speed as 3.3Mbps while it's actually 1Mbps, as advertised and tested through speedtest.net.

There are no LED for the ethernet ports to either indicate connectivity or the speed like 100/1000Mbps.

The antennae are integrated within the device which seems to reduce the range.

Other Thoughts: There are two LED at the front; one for power and another for showing internet connectivity. Both LED can change colors form orange to green.

The WAN / internet LED is a smart light in the sense that it senses an actual connection to the Internet and not just a cabled plugged into an ethernet port.

At the back there are 5 gigabit ethernet ports, one for WAN and 4 for LAN connectivity. There's a power switch and WPS, reset buttons.

The router is powered by a 120V/230V wall wart with slightly short power cable.

The web interface is the usual DLink orange/ grey interface with additional menu items tailored for this specific router.

To test Wifi the router was setup at a height of 3.5 feet from ground and the laptop (Macbook pro retina display 15" also kept at similar height). I used 5Ghz Wifi Channel 36 as well as 149. It works well with a Macbook pro retina, A macbook pro 15", and a mobile device viz. Nokia N9.

WiFi throughput between a wired gigabit server and my Macbook Pro 802.11n using the 5GHz band ranged from 50Mbps to 80Mbps, which is marginal at best.
During the test no other device used the channel.

WAN ethernet port supports Gbps, and the router claims to support true gigabit hardware routing. It may be a great feature for extremely fast internet connection, but with my 10Mbps down / 1Mbps up connection, it disabled QoS bandwidth shaping and SPI firewall and produced no perceivable difference in normal web browsing use.

With true gigabit routing enabled, QoS traffic shaping was disabled. To test the performance as a home user, I started a file upload session to a web server and simultaneously used speedtest.net to check my bandwidth and latency. Latency increased quite a bit from 11ns to 300ns, speed of opening webpages slowed down, even though download bandwidth stayed at 10Mbps. I would thus favor QoS over true gigabit routing for my type of xx MBps internet connection.


A cat6 cable instead of a Cat5e could have been bundled with the router considering it's a gigabit router.
