1 out of 5 eggsNo so good

Pros: Giga Switch

Cons: Bad signal strength and throughput, no matter what settings were applied in firmware. WAN LED never flashed when powered on and never worked when ethernet was plugged in.

Other Thoughts: I own a ERS350 which I was happy with until recently the WAN port quit working. I reset and factory restored firmware, swapped cables with no resolve. My 350 has great WiFi signal and throughput too so I purchased the 900 to replace my crippled 350. I am disappointed to say the least with the 900's performance. This is the worst engenius device I've owned. I've owned 5 total business and consumer routers/repeaters. The unit I received must be a lemon which could be why they were on sale. Bad batch! Returned

2 out of 5 eggsEnGenius ESR900

Pros: Quick and easy setup with plenty of features. This includes the ability to use QoS to limit bandwidth to a range of IP's. The ability to assign specific IP's based off of MAC address, and easily define MTU of packets. It even has a pretty basic monitor that shows network traffic which has been great to identify why the network may be underperforming. The device also provide excellent coverage for my home, which is larger than most.

Cons: The device drops my connection randomly when connected wirelessly. This appears to be a DNS issue with the router as I'm able to still ping external IP addresses. This issue may be limited to Static IP's, but is rather annoying, especially to the now technical users in my home.

A fix was recommended by the company, to flash to ESR900 Firmware v1.2.2.23 (12.20.2013) and reset to factory defaults. This does not fix this issue.

Other Thoughts: This may be a solid router for those who don't experience the DNS issue, but I would not recommend it to my friends or family. If this issue did not exist, I think it would be a pretty solid product.

2 out of 5 eggsDon't waste your time

Pros: Decent speeds at 5ghz

Cons: Low Range, slow 2.4Ghz speeds, sharing files are useless

Other Thoughts: Bought this to replace my TrendNet N300 router. Wanted the better speeds, but that ended up being a waste, really wish I could return this thing.

first off the 2.4Ghz range is pathetic. In the home office, the PC there used to be 4/5 bars at about 80Mbs with the TrnedNet, with this it has gone down to 3/5 Bars and 65 Mbs. Pathetic.

The 5Ghz, is fine, again as long as you're close. The Range on this is not good at all, going to the same Office on 5Ghz drops down to 4/5 bars.

Sharing Files, not worth it either. It only shares a portion, and getting it to share a directory with more than 20 files in it, forget it.

Overall, not happy, I would not recommend this router.

Manufacturer Response:

Hi Swan,

We appreciate your time in posting your comments and feedback.

Slow wireless connectivity can be caused by various factors. Perhaps changing some settings might help your connection. Please scan the area for other wireless signals and change the wireless channel that is set on the ESR900 to a channel with less congestion. On the 2.4GHz radio try setting the channel bandwidth to 20MHz only and please make sure that the TX power is set to 100%. We also recommend that you set the wireless security to WPA2-PSK(AES) and to update the firmware to the latest version.

Please allow us to do some troubleshooting with you. You may reach us through our number at 1-888-735-7888 (Monday – Friday, 8:00am – 4:00pm PDT) or e-mail us at (Saturday, Sunday 8am - 4pm PDT). Our support team would be glad to be of service to you.

Thank you for your patience and we apologize for the inconvenience.

4 out of 5 eggsgreat for what you pay for still some bugs

Pros: Great speed and dual band.

Cons: The streaming usb on router ins not compatible with my hard drive. Needs better Indicator LEDs.

Other Thoughts: Setup has a easy use design that can get you a basic setup, but if you want some advanced features you have to do a little digging. That still was not that hard to do. Does look like a smoke detector.

Did you find this review helpful? Yes No

4 out of 5 eggsGood Features For The Money

Pros: I recently reviewed the EnGenius ESR1200 and this product is nearly identical. The primary differences are that this ESR900 offers a potentially faster 2.4Ghz band (450 vs 300Mbps) and a faster 5Ghz band if using wireless N (450 vs 300Mbps). If you are however using the new 802.11ac standard the ESR1200 might be a better option as it supports the new standard and the ESR900 does not.

Although nothing to write home about, the 5G band connection speed is adequate. Using a Netgear WNDR4100 450Mbps adapter the connection speed fluctuates between 162 and 243Mbps. Compared to the steady 108Mbps I experienced on the ESR1200 5G band this is a tangible improvement. Overall there is about a 25 foot distance, 2 walls, and a stairwell between the router and my PC.

Aesthetically, this device bears greater resemblance to a smoke detector or a Roomba than a router. This could be beneficial for mounting as it's more likely to blend in with neutral wall or ceiling fixtures than some of the colorful/monolithic designs from other manufacturers.

The device seems well ventilated with vents on the bottom, sides, and above the RJ45 ports. This should offer some degree of flexibility in placement of the device. I've had heat issues with multiple access points in the past but so far this device seems cool or at least barely warm to the touch.

This router offers a plethora of premium features for a relatively low price. I own a Netgear WNDR4500 which is basically the same router on paper but costs more than double what this model does.

I experimented with EnShare on the ESR1200 but hadn't had a chance to use the EnShare Mobile app until reviewing this model. I have to admit I was skeptical of this app but have been fairly impressed by it. I already use a media sharing app on my phone called subsonic which works wonderfully but requires a small subscription fee. This app being free with the router is a nice perk. My Netgear router has a media sharing service as well but does not have an associated app to use on mobile devices so EnGenius wins in this category for me.

Cons: With a noticeably faster 5G band I was hoping to see similar improvements with the 2.4Ghz band as well. This hasn't been my experience however. Connecting with the same adapter as before I was only able to retain a 156Mbps connection on the 2.4Ghz band. In fairness, there is significantly more 2.4Ghz wireless traffic in this area which no doubt plays a role in connection integrity. I did however test all channels and 156Mbps was the fastest stable connection I was able to achieve. The ESR1200 I reviewed was at an equal disadvantage and still managed nearly 300Mbps on this band.

My Netgear WNDR4500 incorporates a DC power brick which connects to your power strip with a standard ATX power supply AC cord. The ESR900 (like the ESR1200), however, uses a standard AC/DC adapter with wall prongs built into it. I prefer NETGEAR's approach to this as plugging the large AC/DC adapter directly into a power strip gets in the way of outlets around it.

This device has no lights for indicating individual wired connections.

Rubber feet would have been a plus as the router is light weight and slides around easily if not wall mounted.

Other Thoughts: If you happen to be deciding between this and the EnGenius ESR1200, the decision is simple. If you use an adapter which utilizes 802.11ac (or plan to upgrade to it in the future) than the ESR1200 should be your choice. Otherwise, I would select the ESR900 as its 5G band seems superior for non wireless-ac devices. And while my experience with the 2.4Ghz band wasn't excellent it was still adequate and certainly offers greater headroom if you can achieve a clean enough signal.

My primary router is a Netgear WNDR4500 N900. On paper it is very similar to the ESR900. Both are dual band and support a maximum connection speed of 450Mbps per band. Both feature 4 1Gbps wired ports in addition to the WAN port. Both feature a USB port for media sharing (WNDR4500 has 2), and both feature a media sharing service which is accessible locally or via the internet. These are what I would consider to be the premium features of these two routers and they are basically the same.

However, the WNDR4500 seems to offer a substantially stronger signal on both the 2.4 and 5Ghz bands. Throughput also seems to be superior on the Netgear model. In the few weeks I've used the ESR900 it has required 1 hard reset, whereas the WNDR4500 has never required one in nearly a year of constant operation. That being said, the price of the Netgear WNDR4500 is more than double that of this EnGenius ESR900. Quality and performance come at a price and the ESR900 sacrifices some in order to provide a nice set of features at a good price. I prefer my WNDR4500 overall, but I wouldn't hesitate to recommend this ESR900 to anyone on a budget and in need of the features it has to offer.

4 out of 5 eggsEngenius odd Mixture #3

Pros: This is the final review on my part...the firmware update from 1.01 to 1.10 has resolved the slow page load issues I was experiencing. The router has zero issues with stability, the machine never restarts unless I perform a reset and al connections have been stable and reliable.
Qos appears to be working just fine, youtube videos load immediately and playback without stuttering or dropping frames as far as I can tell.
Range is excellent and better than my old Netgear N600 router by a fair distance.
Signal strength is excellent and throughput is either the same or better than my old N600 as well.
This router performs flawlessly now and has no other issues I can root out. Updates are quick, timers display remaining time on reboot, reset, and are much appreciated.
This router has an odd mix of tools available and in a rather weird drop down menu style left panel on the gui page. These tools are ok to use if you have some skill sets with networking but could get you into some trouble if you do not know what you are doing.

Cons: No cons I can find now except one quirk!

Upon performing the firmware 2 blue LED's for 2.4 and 5 Ghz wireless radios both flash in unison and continuously. I can't tell which one has traffic on it nor when the traffic is moving through the router. Prior to the firmware flash...both LED's were illuminated when the respective radio was enabled and only flashed when traffic was both flash together all the time. This is frustrating when trying to determine who is on your router and what band they are on unless you log in to see what devices are connected and even then, you may have connected devices without descriptors to ascertain whom is connected.

Other Thoughts: All in all, this is a very nice router that has excellent range, performance is reliable and stable, connections are rock solid and stable and the router does enhance/extend the range for the 2.4 ghz wireless by about 15% range wise and about 10% on the 5 GHz radios compared to my old Netgear N600 WNDR 3700 v1 and with a reduced price at $76 this is a bargain/steal.
I have no problem recommending this for anybody wanting to upgrade the current network hardware, the shape lends itself to ceiling or wall mount and is small enough to allow to sit on an unused corner of a file cabinet or desk!
This is a solid entry for the affordable networking hardware for end users in a home or small business that makes upgrading a positive experience that provides tangible evidence that your upgrade was worth it.

4 out of 5 eggsGood router for the Money

Pros: Small footprint, Cloud Sharing Ability, Pretty good range, easy initial setup, Dual Band, Streamed Multiple devices from the same local cloud usb file without Lag. HD Steaming, proprietary surveillance camera ready. Gigabit wired, VPN ready

Cons: Best if you use their version of Camera, App is a still a little buggy, Router control Panel not the easiest to navigate but not too difficult.

Other Thoughts: Update this firmware to 1.1 immediately by downloading to wired computer then update from computer. Solved lots of issues at first with the wifi.

5 out of 5 eggsIt's a 'walk-off home run' of a router

Pros: I received the router and the installed firmware was 1.01 which I immediately updated to the current version, 1.10.

The unit itself is built very nicely and to the naked eye could even be mistaken for a smoke detector. In that regard, I think it would be a cinch to mount this upside down on a ceiling of your home or business, which would easily help optimize your wireless speeds by mounting the unit at a high point. It has a nice sleek white color with the inner champaigne colored ring and easily readable ports and icons. The lights on top of the unit are primarily blue, with the power light being amber. Everything else is internal to the unit, including the wireless antennas. Personally, I prefer having the internal antennas, although if your needs or requirements change, you cannot upgrade the unit with stronger antennas like you can on most of the units that have removable antennas. I really like how the firmware is laid out, along with the various splashes of purple colors and the assorted icons. I think there’s enough in there to walk an uneducated home user through the process of setting this unit up with their home network, including the wizard, but there are also quite a bit of options for the ‘advanced’ or ‘expert’ level network users out there.

Setting up the router for my home network was very easy and within minutes I was sharing my 30/4 Charter cable internet in my home wired across 2 Windows 7 Professional 64-bit workstations, a DirecTV Genie HD DVR receiver, a Xbox 360 Pro (fat), and wirelessly across 4 Android smartphones, 1 Android tablet, and a Playstation 3 (fat). The router’s speeds over GbE are excellent; using the freeware LAN Speed Test (Lite) v1.3.1 application, I achieved speeds of 712Mbps (down) and 792Mbps (up) from PC to PC using Cat5e. My WAN speeds were also excellent - with Charter I get 30Mbps minimum (down) and usually pull closer to 40-50Mbps depending on things; with the ESR900, I did get an average (over 5 tests) of 32.3Mbps (down) and 4.252Mbps (up) with a ping of 17.8ms.

Wireless performance of the unit is extraordinary, even from further distances. Using the 2.4Ghz radio, 3’ away from the router in the living room, I achieved 32.076Mbps (down) and 6.112Mbps (up) with a ping of 30.8ms and a signal strength of -46 dBm. In the bedroom, from 25’ away and through 3 walls on the same floor, I achieved 21.432Mbps (down) and 6.124Mbps (up) with a ping of 29.2ms and a signal strength of -53 dBm. On the 5Ghz radio, again 3’ away from the router in the living room, I achieved 52.55Mbps (down) and 6.022Mbps (up) with a ping of 27ms and a signal strength of -46 dBm. In the bedroom, again 25’ away and through 3 walls on the same floor, I achieved 49.336Mbps (down) and 6.074Mbps (up) with a ping of 27.8ms and a signal strength of -60 dBm. This is incredible! My ping was a little higher on both radios, but the transfer rates were identical (or better) to the GbE speeds! (See 'Other thoughts' for more Pros.)

Cons: I really have to nitpick to come up with cons of this unit. The top lights are a little bright (but they are also pretty small). I wish it had a wireless radio on/off switch, but the wireless can be disabled easily in the firmware itself. A 2nd additional USB port on the unit would be nice to have, but the lack of more than 1 isn’t really a deal-breaker.

The only other con I can come up with, as I mentioned before, is that the wireless antennas are all internal to the unit and therefore cannot be removed or upgraded. I don’t really think that’s a problem, because my testing proved that this unit has excellent radio signal coverage, but it might be an issue for people trying to get signals on different floors or in a home or office of greater size.

Some people may find the customization and configuration of the router a little lacking; I don't have a problem with it myself. It looks a little simplified, but you can dig deep and drill down and there are a lot more options underneath that don’t appear to be there on the surface.

Other Thoughts: Additional 'Pros':
The USB port is an excellent addition and makes the router also function as somewhat of a NAS/shared media unit. Testing with both an external 750GB USB 2.0 HDD and 32GB USB 2.0 thumb drive, I was able to easily stream a 1080P Blu-Ray rip without any hiccups or slowdowns on both wired and wireless devices. I also like how any connected USB devices can be browsed through not only SMB in Windows, but also web browsers as well as Windows Media Player, VLC, etc.

On each of the wireless radios, you can have up to 4 SSID’s on each (so 8 SSID’s total). On any of these tertiary SSID’s, you can set them up as Guest WiFi access which helps if you are working on cleaning up a malware infection and you need to get online to download malware definitions or applications but you don’t want to risk cross-network contamination of your healthy devices.

The router also include VPN passthrough which helps for users that work remotely from other locations, and even includes WOL (wake on LAN) functionality to remotely power on a device that supports WOL from within the router itself.

Closing thoughts:
As an educated network specialist with an Associate’s Degree in Network System Administration, I’ve worked with all sorts of equipment, and let me say that the ESR900 earns my full recommendation just as easily as a Cisco Catalyst would. It’s easy enough for inexperienced home users, but robust enough for someone like me who is more experienced with networking equipment and security, and wants more control. The performance of this router across the board is all flawless; wired, wireless it doesn't matter – this tiny little wonder takes it all and keeps up without a glitch. Even trying to bomb the unit with traffic over BitTorrent or by downloading an Ubuntu ISO on 4 devices at once, this thing just ran like a top. I was looking for a gigabit router to replace my aging Netgear WNR834B v2, and I found more than a suitable replacement – I found something that exceeds all expectations. This is the first EnGenius product that I’ve owned, and after this wonderful experience, it will definitely not be the last.
