5 out of 5 eggsExactly what I needed

Pros: Small
Works perfectly after firmware update
Ethernet cable unnecessary after initial setup

Cons: Required firmware update before use, because it kept spontaneously rebooting for no reason
Instructions are lacking, especially for a firmware upgrade

Other Thoughts: Firmware update is MANDATORY for solid operation.

I was eager to get this because the wifi router in the center of our elongated office building didn't reach all the way to either end. So I bought two of these to place near each end of the building. The wizard setup was a breeze and once complete you don't need the ethernet cable anymore (the instructions do NOT specify this). Once configured you can unplug and relocate. Since there are no cables it kinda looks like an air freshner you plug into the wall.

But it spontaneously reboots for no reason. I went to the TP-Link website to find the firmware upgrade and applied it. This resets to factory defaults so I had to go through the auto-setup again, which is very easy. Now with the new firmware it is rock solid and provides full strength wifi to every place in my office building.

This accomplished exactly what I needed. I definitely recommend for the $28 price.

3 out of 5 eggsDecent, when it works.

Pros: When it works, it works great. I'm currently using one unit as an access point for my bedroom PC, and as an extender for the wifi dead zone in the bedroom. I get a decent signal from my room, about 20-60% improvement depending on situations.

Easy WPS setup, and easy to setup using the GUI.

Cons: I bought two units, the first unit worked for a few days then stopped working. It shows my network connection as Public and no connection to the internet. A reset would not fix the issue. The second unit see below.

Constantly having to reset unit when power goes out. Not a huge con, but a very annoying one seeing as how it's storm season. Slow to connect to router. Occasionally loses connection, which requires me to hard reset the unit to fix the problem. To get the best signal for this unit, I had to place it much higher using an extension cord instead of my wall outlet.

The TP-LINK GUI greatly exaggerates the connection signal and speed of the unit, I compared it to what my router's GUI shows.

Other Thoughts: I bought two units using a gift card I received, so I'm not very upset, but had I used my own money I would return them ASAP.

Make sure to download the latest firmware updates to take full advantage of these units.

5 out of 5 eggsGreat Range Extender

Pros: Very Easy to setup using WPS on my router & the TP-Link extender.
Obtaining and installing the Firmware update was also quite simple. **Note you may need to do the WPS setup again after installing the firmware.
Once placed in my upstairs, I immediately began seeing full strength wireless throughout the upstairs. My internet/streaming has been much faster and more reliable than my previous solution.

Cons: None at this time, I will update the review if I encounter any issues.

Other Thoughts: Overall, I am very pleased with this piece of hardware. It was very easy to setup, update, and install. All of my wireless devices in the upstairs of my house are now working much faster without issue. I couldn't pass up the price when I saw it and I am glad I bought it.

2 out of 5 eggs

Pros: good range, easy to set up.

Cons: used it for 4 months, constantly dropping connections since the first few weeks of using this product.

Manufacturer Response:

Hello Customer,

Thank you for checking out our Range Extender.

We are sorry to see that you've had some connection issues.

One suggestion we have is to change the Wireless channel width to 20 MHz if it isn't already on this setting.

This has been known to improve stability and speed.

I would also suggest setting this device up with a Static IP address instead of using the Smart IP feature.

This can also help prevent some disconnects that you may encounter.

If you have any questions or concerns then feel free to contact me directly at

Best Regards!

4 out of 5 eggsJust well

Pros: Good looking, well designed.
More stable connection than my laptop.
You can plug another appliance in the same wall outlet, but trying.
The ethernet port is useful.

Cons: -It have almost the same signal than my laptop at the same distance and place from my router.
-The MSRP price is too much because there are routers with the same signal at a close price.
-The WEB GUI is the same as a router from 2007
-You can't hide WIFI extender BSSID
-It takes too long to connect and extend.

5 out of 5 eggsBest Wireless Router!!!!

Pros: Sleek and stylish design that no one else has out there.
The easiest setup I have ever had for an extender.
The unit stays very cool compared to other extenders on the market.
150 Mbps speeds on laptop and ipad.
The blue lights that tell you your signal strength are very helpful and accurate.
Setup was as easy as pushing WPS on the unit and my router. The signal stayed named the same, not assigning a new SSID, making the wireless network more stable. Devices no longer jump between a new SSID, that is just the same network.
You can add device after device and didn't slowdown the network.
The Ethernet port at the bottom is perfect for adding on devices that don't have wifi. It keeps you from having to run cable a long distance.
The blue LED lights are easy to see at night and are cool looking.

Cons: 5ghz is not supported. There are no other cons to a near perfect product.

Other Thoughts: I have reviewed other extenders and TP Link extenders and this is the only one I recommend. I had actually bought the product before Newegg sent me the Expert review product. The prior Powerline Extender by TP Link had countless issues. I am a huge TP Link supporter.

My setup: Desktop Duo2Core, Lenovo laptop T430, ipad, LG BluRay with Wifi, Netgear 3700 Wireless router.

Save your money and buy the best extender on the market for under $30. I bought mine and was even sent a TP Link Powerline extender and could have returned the one I bought. Newegg was never going to get back such a great extender.

4 out of 5 eggsIt works well

Pros: Easy set up. It works even when connected to a short extension, and not directly to the wall. Boosts signal to full bars to rooms that had almost no signal,

Cons: Set up is easy but also somewhat confusing. There are vertical bars at the bottom that I expected to light up, but did not. Those are for Ethernet connections I expect. The lights that light up for wireless are the ones in the circle.

Other Thoughts: Nice design, easy to set up halfway between router and end point with extension, I had no outlet in the right spot.
