4 out of 5 eggsGood router

This review is from: EnGenius Xtra Long-range ERB300H 4-Port Wireless-N Media Bridge and Range 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 Xtra Long-range ERB300H 4-Port Wireless-N Media Bridge and Range 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 Xtra Long-range ERB300H 4-Port Wireless-N Media Bridge and Range 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?

5 out of 5 eggsBudget media access without cables

This review is from: EnGenius Xtra Long-range ERB300H 4-Port Wireless-N Media Bridge and Range Extender

Pros: This device has been working without a hitch since I got it setup. I am using this for streaming media content to an older blue ray without wifi and it gives me additional ports for other devices (xbox, etc.) The device is connected to a FIOS router using WPA.

Cons: It took me two tries to get it setup correctly. Reset procedure took a few google searches to figure out, but if I had done it right the first time, this would not have been necessary.

4 out of 5 eggsAlmost gave up but...

This review is from: EnGenius Xtra Long-range ERB300H 4-Port Wireless-N Media Bridge and Range Extender

Pros: Fast, easy setup. Great speed. Upgrade the antennas, just do it.

Cons: 2dbi antennae. Difficult to re-access the web interface.

Other Thoughts: I had this for a year and it was flawless. Powerful, simple, fast. Then it started dropping me, so I wanted to log back onto, as the manual states. Nope, no access. I reset and no access (my theory is this is a reset, not a reset to factory). SO I took another person on this site's advice and entered into the url line of my browser: erb300h/. Voila, the interface was back, I could now access my unit, update the firmware to 1.1.5 and set it up again. Now things are back to normal. I had ordered another unit as a backup the other day, and my faith in this product is restored for now.

4 out of 5 eggsISP issues

This review is from: EnGenius Xtra Long-range ERB300H 4-Port Wireless-N Media Bridge and Range Extender

Pros: Price ($30)
Great at extending Wifi
EnGenius Customer Support was helpful.

Cons: Customer Support had me wait for 20min to patch me through to a person.

Sometimes the extended Wifi signal isn't a noticeable increase.

Other Thoughts: If you rent/lease a modem from your ISP or your ISP blocks you from accessing your modem through its IP address simply turn off your computer's wireless network functions, connect a ethernet cord (one is included) to your new wireless range extender (power supply also plugged in) and change your primary DNS to and your secondary to Then go to (while not connected to your internet but rather this device) Log in with the credentials Username and Password: Admin From there you go through some tabs at the side to advance setting and find your Wifi name. Then enter your normal WEP key or whatever you use and it will ghost copy your Wifi. Then reactivate your Wireless to reset your DNS settings. (There's probably a part that I missed about holding the button down, but for the most part it's in the manual) I hope I helped a little.

5 out of 5 eggsGreat range extender

This review is from: EnGenius Xtra Long-range ERB300H 4-Port Wireless-N Media Bridge and Range Extender

Pros: Easy set up as range extender
Solid signal

Cons: None yet

Other Thoughts: The price was great. The set up couldn't be any easier. Let it find your network, put in the security for your current network, put in the security for the extended network, DONE.

My neighbor is so happy about his improved Wi-Fi signal.

5 out of 5 eggsExtend the Bridge

This review is from: EnGenius Xtra Long-range ERB300H 4-Port Wireless-N Media Bridge and Range Extender

Pros: Cost a few dollars more than others, but it works beyond expectations. I bought this to extend the range of the wireless network. It took 14% to 34% wireless signal and boosted it 1o 100%.

I had desktops which I needed to hook up, so I took the next step. I wired this to a Netgear wireless/wired router and bridged the wireless network. I created a new wireless SSID (I had my reasons for this). I was able to connect the wired desktops to the Netgear. Wired and wireless devices are all on the network. I recommend this product.

Cons: The interface is simple. Just let the wizard do the job for you.

4 out of 5 eggsDecent Bridge

This review is from: EnGenius Xtra Long-range ERB300H 4-Port Wireless-N Media Bridge and Range Extender

Pros: Nice external antennas
Comes with mounting screws
Simple setup
4 ports

Cons: Limited wireless security combinations (see below)
Reaching the console after setting up as a bridge is undocumented
CAT5 cable included is 21 inches, which I found to be fairly useless
Either low workmanship or unlucky (see below)

Other Thoughts: I bought this as a bridge for some machines that were just a bit too far away from my main wireless access. This device is talking to a router running DD-WRT. When attempting to hook up to the network it can use WPA and TKIP or WPA2 and AES but it didn't allow WPA2 and TKIP as one of the choices. If your router is configured that way you can change it to be WPA2 AES+TKIP. This will drop some of your clients although they will eventually reconnect.
I didn't see any way to get back to the console after you've placed the device in bridge mode other than reseting it. The manual is rather short because it's simple to set up. But it doesn't tell you how you can do this and I'm not sure you even can.
My device has something loose inside it. As soon as I picked it up you could hear something inside it sliding around. Tilting it back and forth you can hear the item moving. I hope it's a pieces of plastic and not metal.
It configured and worked so I'm not returning it.
After installing this, I think of this as a value product not a high quality product.
Hope this review helps somebody.

3 out of 5 eggsworks well... client-bridge mode quirks

This review is from: EnGenius Xtra Long-range ERB300H 4-Port Wireless-N Media Bridge and Range Extender

Pros: simple setup for network repeater mode.
EnGenius Tech Support: responsive, helpful.

Cons: apparent quirk (possible bug) effecting Windows 7 dhcp clients when used in Client Bridge mode and Static-IP assigned to ERB300H (firmware v1.1.5).
See Other Thoughts.

Other Thoughts: Quirk (possible bug) with Windows 7 DHCP client and ERB300H in Client Bridge mode (firmware v1.1.5):

Upon connecting to the network, either by ethernet to ERB300H switch ports, or by WiFi to primary router, the primary (a WHR-HP-G300N w factory installed dd-wrt) offers proper DHCP values for gateway and dns, but ERB300H updates them so that dhcp-server and dns-servers point to the ERB300H instead of the primary router, resulting in Windows 7 clients having LAN access only. While this issue did not effect my Android Phone or Linux Mint box, a packet capture confirmed the ERB300H did send out the incorrect values. Not yet sure why Windows used them, but Linux did not. This occurs with the ERB300H in Client-Bridge mode and it's IP address statically configured (the default), regardless of the values entered in the ERB300H LAN DNS fields.

WORK-AROUND FIX: after switching the ERB300H IP address to 'Dynamic', all has been well.
