4 out of 5 eggsImpressed

This review is from: EnGenius ERB300H 4-Port Wireless N300 Media Bridge and Extender

Pros: There is a manual
Output is great.
Relatively simple to configure

Cons: Not really sure about what the lights all mean. The instructions are focused on how to connect/configure it, not on the what the light status means.

Other Thoughts: I bought one of these over a year ago and have had it in stock until today. we tested it out about a month ago and used the manual method for joining it to my network. Those settings were still there, even after it connected to customer's network via WPS.

Unlike another reviewer's comments, WPS worked flawlessly for me. Because I had an existing SSID configured, my repeated SSID was not the same as the base network, but that was easily changed and customer was very happy.

I found it very capable of pulling in a weak signal, and the resulting repeated network was super. For the price, I haven't found a better unit.

3 out of 5 eggsOkay as bridge but not great

This review is from: EnGenius ERB300H 4-Port Wireless N300 Media Bridge and Extender

Pros: Easy configuration and excellent stability.

Cons: In Bridge Mode: Wired clients do not obtain a DHCP address from my Microsoft SBS 2011 DHCP server. I have a reservation on my DHCP server for the wireless bridge. The ERB300H gets the reservation IP from my SBS 2011 server just fine. However, anything plugged into one of the 4 Ethernet ports will not get an IP via DHCP.

When I assign static IPs to the nodes plugged into the ERP300H they are able to communicate just fine on my network. However, with a simple PING to anything plugged into the ERB300H (from a laptop wirelessly connected to the same SSID) I am able to see part of the problem . After the PING test succeeds (meaning replies) I look at the local ARP table on my wirelessly connected client and see that the MAC address of the wireless bridge is associated with the IP of the device wired into the wireless bridge instead of the proper MAC address.

In other words, when I ping my Samsung TV for the first time after restarting my wireless client my local ARP table is updated with an entry. The MAC address associated with my TV is the MAC address of the ERB300H within the ARP table instead of the real MAC addressed tied to the NIC within the TV.

This tells us that the ERB300H is masking the MAC address of the client devices plugged directly into one of its 10/100 Ethernet ports instead of passing the MAC through as one would expect. With this being the case, no wonder my DHCP server isn't handing out an IP address to anything plugged into one of the 4 10/100 Ethernet ports.

Other Thoughts: If you plan to use this as a wireless bridge be prepared to assign static IPs to anything you wire into one of the 4 Ethernet ports.

4 out of 5 eggsWorks as it says

This review is from: EnGenius ERB300H 4-Port Wireless N300 Media Bridge and Extender

Pros: Worked great as a bridge
Ability to swap in nicer antennas
Includes mounting hardware

Cons: Firmware pages seem clunky

Other Thoughts: This wireless bridge from EnGenius works pretty well. Just don’t let them fool you into thinking it’s some fancy media device. When I looked at the box I was almost expecting there to be HDMI ports and all kinds of fancy media related features, but no, it’s just a simple range extender / wireless bridge.

In the box was the device, two antennas, mounting screws with drywall anchors, a CD, and paper manual in many languages. It’s unusual nowadays to see mounting hardware actually included so that was nice, but the drywall anchors seemed a bit silly, as this is an extremely lightweight device. I’m not completely sure what the CD is for and never bothered with it, but nice to note it was a full size CD instead of the silly mini-CDs some companies are so fond of. The unit itself is a pretty typical looking network appliance, no frills, but looks nice. The LEDs cannot be turned off via any means I found, which is a bit of a downer as I’ve started to see that on many devices recently.

Setup was relatively easy, although people who don’t have a PC with an ethernet port need to steer clear, as it’s pretty much required if you can’t get WPS to work. While navigating the menus I couldn’t help but get a flashback to 90s era webpages. EnGenius could definitely do a better job of making a nice interface. Nothing very interesting to note feature wise, except a scheduler which allows you to customize various start/stop times of services.

I used this device in bridged mode to effectively “hardwire” my PC which was using a USB wifi dongle. The speeds have been excellent so far. I’ve streamed HD media with no issues so far. Overall this device worked and I could definitely see it being useful to essentially add four ethernet ports behind a TV or in an office. $50 at the time of this writing doesn’t seem bad for that capability, just don’t let the box fool you into thinking this is anything more than a simple wireless bridge / extender.

1 out of 5 eggsrun away!

This review is from: EnGenius ERB300H 4-Port Wireless N300 Media Bridge and Extender

Pros: small size.... easy assembly

Cons: First one was dead out of the box.... couldn't bridge even in the same room! Easily honored RMA . 2nd unit worked fairly well (lots of drop outs) then croaked after 2 months... would not receive / transmit just like the first one.

Other Thoughts: Just buy a new generation router..... cost more up front .... but zero waste & aggravation.

2 out of 5 eggsI seem to have a defective unit

This review is from: EnGenius ERB300H 4-Port Wireless N300 Media Bridge and Extender

Pros: + Inexpensive
+ Supports easy antenna upgrades
+ Performs well when it works
+ Supports WPA2 with AES encryption -- the best available home wireless security.

Cons: - WPS (Wifi Protected Setup) does not work!
- Doesn't encrypt/hash passwords internally. This only matters if someone logs into the admin interface where they can read easily your password.
- Manual setup is awkward and clunky.

Other Thoughts: This review is a re-post because my previous one seemed to go missing, but it's a good thing since I have had more time to test the unit.

- My unit loses its connection more than once a week, which leads me to suspect that my unit is defective. That's understandable -- every product has a certain defect percentage. I have to manually re-configure the network (with the same details it already has stored) to reconnect. The unit reports no problems when it loses connection -- devices simply cannot talk to it until reset. Power cycling does not help.

- The manual highly recommends using WPS, which allows setup with just 2 button presses, but as other reviewers noted it doesn't _fully_ work. WPS _DID_ get my unit on the network and got it an IP address, but I had to manually configure the network name, security key, and other details. This is annoying, but you only do it once unless you got a bad unit like

Manufacturer Response:

Hi Charles B.,

We appreciate your time in posting your comments and feedback.

We are sorry to hear about your experience with the ERB300H. Repeaters need very good wireless signal from the wireless router to work properly. Perhaps adjusting some wireless settings will resolve your issue.

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

Thank you for your patience and we look forward to hearing from you.

5 out of 5 eggsVery good range extender and tech support

This review is from: EnGenius ERB300H 4-Port Wireless N300 Media Bridge and Extender

Pros: It is very easy to set up and use. Had a technical for it to use on another application and called their tech support. It was very easy to talk to a human that knew the antennas had to be kept together. I wanted to put one antenna inside a building and one outside but it is not possible. He treated me with respect and seemed like he was very knowledgeable, did not have to put me on hold while he looked up the answer.

Cons: None

Other Thoughts: I will probably be buying another one.

4 out of 5 eggsGood router

This review is from: EnGenius ERB300H 4-Port Wireless N300 Media Bridge and Extender

Pros: Works well. The range is pretty great. It reaches the basement from my upstairs. Descent speeds too.

Cons: I have heard that the support for this product is pretty much non-existent. I haven't personally had to call them though.

3 out of 5 eggsok extender, marketing kills it

This review is from: EnGenius ERB300H 4-Port Wireless N300 Media Bridge and Extender

Pros: Ease of use - The extender/repeater was very easy to setup (as long as you have an available lan port on a PC and/or a router that supports WPS). Total time to setup took about 2 minutes tops to be extending/repeating my wireless signal.

Nice design on the packaging (if you care about such things), really was reminiscent of TP-Link packaging to be honest, surprisingly nice packaging design.

Nice small form-factor hardware. Nice design and smaller than typical form-factor (mostly because of the bezel on the edges).

Decent price w/ discounts.

Cons: Here is where I begin to take issues. The device is marketed as an HD Media Bridge & Range Extender. In my opinion this is really not capable of being called a bridge due to the 10/100 lan ports (meaning anything wired to this device is limited to at most 100 MB per second). This severely limits the ability of any wired devices that are connected to this 'bridge'. 90% of my HD rips are over 100mb/s. Using this to stream any MKV files resulted in stuttering, which is atypical from my media server. I can stream to my wired devices and wireless devices w/out issue, however, with this 'bridge' I am unable to do so enjoyably.

As such, if you're attempting to use this completely as a wireless extender/repeater you are going to be better off (as long as your wireless network is limited to 300mb/s speeds) with this device -- to an extent.

With wireless extension, I am hard pressed to see a need for this device. I was able to increase connection speeds to the device, however, the device's connection to my network was sporadic at best. I could not get a consistent connection to my network from 40 linear feet and one floor down. See my usage in other thoughts.

The cat5 cable included has to be 9 inches long tops. This is pretty typical issue many people report w/ networking gear. However, i've learned to accept this. However, this cable is so short it is virtually incapable of usage. I had to move the device to the rear of my PC in order for it to reach the lan port! I couldn't reach the lan port from the front of the PC. I would have preferred they not even include a cable than to include such a tiny piece of 'cable'.

Setup, while easy, did require either a Router w/ WPS or else a computer w/ a lan port. I would assume most people have one or the other, however, I would also assume that they would accommodate those that do not.

I do not use WPS for a few reasons, security, laziness, and stubbornness. So I refused to use it in this case, which relegated me to pulling my lan connection to setup this device which was mildly frustrating.

Wireless connectivity was less than average for this device to pick up your existing wireless coverage. I typically get a 300mbps connection with a nano sized usb networking adapter. This connection ranged from a green connection to a red connection, which I would assume means i'm not getting a full 300mbps connection to my router. I could not validate the connection speed in which it connected to my router, but the device always showed my devices were connected to it at 300mbps, which could not have been true.

Other Thoughts: I attempted to utilize this device to replicate my current Home Theater networking hub. My Home Theater is 40 linear feet and one floor below my main router. I currently run a cat6 line to a GS108 switch. The switch powers my AV gear (HTPC, PS3, 360, BD Player, Roku, Google TV, and an NTV550).

Connecting to my server to stream HD media content was not useable via the wired connection. Via the wireless connection I was able to stream, but it seemed like anytime any other wireless activity happened my connection to the network dropped from green to red, thus rendering the connection to my server as unreliable and not useable.

Surfing the internet on my connected devices worked fine, however this isn't what the device is marketed as...which is where my biggest complaint comes from...don't market the product like a high end bridge when it lacks the chops to deliver a high end bridge.

Can it stream HD? Sure, if it was sitting next to my router and connected to a wireless device, but i'd just use my router in that case.

Does it have the self-proclaimed 'fast ethernet'? Sure, if you are comparing it to an ethernet connected device from 1998 when it was 10mbps rather than 100mbps.

Does it deliver a self-proclaimed 'x-tra range' coverage? Sure, if you are comparing it to a wireless B spec router from 10 or 15 years ago or maybe an internal 1db boost antenna. The dual 2db boost antenna are not really atypical anymore, it's quite standard, or even sub-standard these days. Not to mention when a nano-sized usb adapter smaller than a penny can obtain a better signal than these two 'x-tra range' antenna, it has to be quite obvious, that you should not be marketing the device as 'x-tra range' anymore.

5 out of 5 eggsWorked quite well, annoying setup

This review is from: EnGenius ERB300H 4-Port Wireless N300 Media Bridge and Extender

Pros: - Filled a gap in my wifi coverage perfectly
- Works well once setup
- Dual directional antenna
- Small form factor
- Wall mountable

Cons: - Setup is stupidly annoying
- WPS didn't function for me
- Not dual band

Other Thoughts: For the money I kind of figured this would at least be dual band. Either way, it works quite well. It came with all the accessories necessary to get it running, and the directions were accurate.

I wish this could be setup by just plugging it into the network, but rather you have to directly connect a computer to get into it and configure it. WPS would have alleviated this issue, but it didn't work with my router. The UI was clunky and slow, but once I got it setup I haven't had to worry about it yet, so I don't think docking an egg is necessary.

Performance wise it worked fairly well, even with two devices on board (I was using it as a repeater/extender). I ran a few speed tests and got up to around 30MB/s.

I did a quick test as a bridge and it worked pretty well, as well as any USB adapter I tried in my system. Again, it has to be configured first, so if you are using this for a game console you can't just plug it right in and expect it to work.

There's really not much else to add. It works, it's annoying to setup, but so far it seems to fill its role and do its job. What else can you ask for?
