Extend Your Range

300Mbps Universal Wi-Fi Range Extender – TLWA850RE

TP-LINK's TL-WA850RE is designed to conveniently extend the coverage and improve the signal strength of an existing wireless network to eliminate "dead zones." With 300Mbps wireless N speeds, Range Extender button, miniature size and wall mounting design, extending a wireless network has never been easier. What's more, its Ethernet port allows the TL-WA850RE to act as a wireless adapter to turn a wired device into a wireless one.


300Mbps Range Extender

The TL-WA850RE can vastly expand the coverage of the existing wireless network. With 300Mbps wireless 802.11n speeds, it is ideal for smooth HD video, music streaming, and online gaming.


Quick Setup, Easy Deployment

Setup is facilitated by the built-in range extender button, quickly pairing the TL-WA850RE with your main router after simultaneously pressing its WPS button. If your router does not have a WPS button, you can access the quick setup mode through the web browser-based user interface. Login credentials are retained internally after setup, allowing you to relocate as needed to generate ideal coverage.


Wi-Fi Your Wired Gadgets

After the range extender is set up, users can connect wired devices such as Blu-ray® players, gaming consoles, DVRs, and Internet TVs to the extender via the Ethernet port. As a result, those devices are added to the whole wireless network and can access the Internet.


Smart Signal Indicator Light

Five signal lights represent the current signal strength that TL-WA850RE receives from the existing router. They can help to find the right location to place the range extender and to achieve the best possible coverage and performance.

3 out of 5 eggsSpend a few dollars more for the WA860RE

Pros: I evaluated the TP-LINK WA850RE along with the WA860RE. The difference is the 860 version has external antennas while the 850 does not. This ended up being significant, as the 850 offers greatly limited range vs. the 860.

As with the 860 model, the WA850RE broadcasts to both wireless clients and the base network over a single channel. This creates interference on *all* connections, whether a client uses connects to the WA850RE or the base station. Combined with the WA850RE being half duplex - it can send or receive, but not both at once - and available bandwidth shrinks to a fraction of the 300 MBps specification. Count on 50 MBps at the most.

Given those limitations, the WA850RE does perform well in some cases, It offers simple setup (either through WPS or a wireless interface) and does indeed extend the range of your wireless coverage. Connections were stable as long as you use the WA850RE as an extender only and don't stray near the limits of its range.

You can browse the web and stream music over the WA850RE connection. File transfers and video streaming are slow at best.

Cons: As I mentioned above, bandwidth is not great. A second disappointment is the limited coverage range of the WA850RE. I found the maximum usable range to consistently be about half that of the $20 more expensive WA860RE. Count on a maximum of 75 feet if there are no intervening walls or other obstructions. Perhaps half that if the signal goes through an exterior wall. In other words, this isn't going to give coverage to your back yard.

When the WA850RE was configured as a DHCP server I saw frequent connection drops, particularly if more than one device was connected at once.

Other Thoughts: There is a wired ethernet port on the WA850EE. This is only useful to connect wired devices to the network. You can't manage the WA850RE over it. The port is only 10/100 rather than GigE. This ends up not being significant as the WA850RE can't hit 100 MBps transfer rates anyway.

This device is only suitable for occasional use. It clobbers overall wireless speeds on the channel it uses because of the interference. I also can't recommend purchasing this unit instead of the slightly more expensive WA860RE. Saving $20 ends up being the wrong choice due to the much more limited coverage range.

4 out of 5 eggsGood product, however limited.

Pros: Smart Signal Indicator
Ethernet Port
2 year warranty

Cons: Single Band N only
Little bulky, blocked the spare power socket
100mbps Ethernet port!
Got warm during use
Throughput was pedestrian

Other Thoughts: I am not a fan of Wireless Extenders, especially single band versions like this one. I took an egg off for the simple fact that single band extenders are generally lousy technology, not TP-Link's fault.

Getting network connectivity to dead spots can be achieved more effectively using ethernet cable, Powerline Adapter kits, upgrading to a new AC Router or even re-positioning your current router.

The issue with single band Range Extenders is that they have to talk to the router and connected devices on the same band, effectively halving the bandwidth to any connected devices (send and receive). This in theory would bring the maximum bandwidth to 150mbps, of course, if you connect a device to the 850RE via the 100mbps Ethernet port, your maximum throughput is reduced further to 100mbps!

Extenders should ideally be located at the mid-point between the router and the location where wireless extension is required. If a basic or old router is being used then range and bandwidth are likely compromised even before adding the range extender and halving whatever bandwidth is available in the first place.

The TP-Link WA850RE is well built and feels like a quality product. It did get warm during use and unfortunately for me blocked the second power socket preventing me from using it. The signal strength indicator is a great idea and in practice it worked very well in letting me know when I was at the optimum location for setup, this was easier than using software diagnostics to look at signal strength to determine best location.

During my testing the WA850RE never dropped off my network and provided a consistent result even though bandwidth speed was nothing impressive.

WPS worked immediately with my Asus RT AC66U, I also logged in to the web interface without issue and the device was easy to setup. I was connected to my network in minutes and I was able to test its capabilities by sending packets of data to and from a remote laptop using Totusofts LanSpeed software. I connected to the laptop using only 2.4ghz N.

Transferring files through the range extender to the laptop I saw speeds of 9.25 megabits per second but when I connected to the laptop using just the router I was able to see speeds of 48.17 megabits per second.
9.25megabits per second is enough to surf the net and send email, but forget streaming video or music.

I can’t say that the TP Link WA 850RE is a bad product as it works as effectively as the laws of physics and wifi allow it to, however I am not sure of a specific group of consumers who would benefit from this product.

This extender is well built like all TP Link products, comes with an Ethernet port, signal strength meter, and was exceptionally easy to set up using WPS or manually. It is inexpensive to buy and comes with a 2 year warranty

If you are not able to run Ethernet, upgrade your router, use Powerline (TP Link have some excellent Powerline kits), then a range extender could be considered. Just remem

3 out of 5 eggsIt works but....

Pros: Very easy setup, up and running in 5 minutes. Range is as good as units double the price. Speed was about 80% as fast as sitting next to router.

Cons: When did boxes change? why do manufactures put more time into the boxes then the product itself?
The unit takes up a wall outlet with no pass thru. How hard would it be to add a pass thru to this thing? with all the electronics we use now a days a pass thru plug would have been nice.
I lost connectivity to it after a couple of days and had to reset the unit which meant I had to find the paperwork for it for the user name, password, and setup address. Why this information is not on the unit I'll never know.

Other Thoughts: Sorry for the short review but I just was not impressed with this unit. I see today the price is 39.99, the price was 19.99 when I was offered this to review. at $20 its a buy and $40 its a pass to better units

2 out of 5 eggsNot without its flaws

Pros: Made signal faster and stronger.
Took my speed from ~7-10mbps to 30+ (for the first two hours)
Light lets you know what its doing.

Cons: Whines when ethernet is plugged in.
Although the signal is stronger, the speed is the same.
Lights are TOO bright.

Other Thoughts: My office is in my bedroom and the router sits in the living room two walls, and a shower away. In total its probably 20 ft away, but I don't get a very good signal.
Why, you ask? Well, I live on the corner of an "L" shaped apartment complex on the first floor. When I go to connect, I can see over 30 different networks all occupying the 2.4 GHz band.

I was hoping to cut through the interference and get the faster speeds I'm paying for, as well as connect my server (which doesn't have WiFi access) to my network again. Bring in the TP-Link Wifi booster.

Checked my speed; 7MBps. Plugged it in, set it up within 5 minutes. Checked my speed. 31MBps. This thing is AWESOME! I'm going to preach this to my friends, coworkers, etc. Plugged in my server and started it up. Got it all connected, and checked the speed. 7Mbps. Ok...well, at least its connected... doesn't do much good as a file server at that speed...And that's when I heard it. A high pitched....whine....

Ok. No big deal. MY stuff's connected whatever. Fast forward a few hours. I'm still working on my computer...keep hearing whine. Check speed. 7Mbps.

Fast forward to the night. Go to lay down. The light lights up the room. The whine is screaming at me. Unplug the Ethernet cable and it goes away.

I dont know what I expect from this review, but I'm close to returning it. I'll give it a few more days...

Manufacturer Response:

Hello Customer,

Thank you for taking the time to check out our Range Extender.

We are glad to see that the speed and performance has increased for you.

The whining sound that you are explaining doesn't sound normal and could actually point to a hardware issue.

One thing that I would suggest is try going into the configuration page of the Range Extender and navigate to Wireless > Wireless Settings.

You can try changing the Operation mode (Range Extender Mode 1 | Range Extender Mode 2).

Both modes interact with your Router a bit differently and you may find that one works better than the other.

If you haven't done so already, we would also suggest that you upgrade the firmware from our site to get the best performance and stability from the device:

Please feel free to contact our Tech support if you have any issues or concerns.

Best Regards!

4 out of 5 eggsVery Good Extender

Pros: -- form factor
-- ease of setup
-- stability

Cons: -- informative, but not intuitive lights

Other Thoughts: I've put several of these in and never had a problem. They extend very well, connecting within 90 sec. to the router through the WPS button. Some things to watch out for:
1. Make sure you have the latest firmware
2. Don't hold the WPS too long or too short of a time; follow the directions. (Otherwise you get a reset!)
3. Have your wireless network drivers updated to latest. I've had multiple problems with wireless devices that cleared up completely with the updated drivers.
4. If you have a power failure or your router reboots, you may need to unplug and replug the extender
5. It's good to have the extender on a different SSID (network name)

4 out of 5 eggsHow am I liking it?

Pros: Wi-fi Extender
User Friendly
Quick Set Up

Cons: None that I can think of

Other Thoughts: I've only had it for 1 day but so far I'm loving this extender. My download speed is the same when connected to the extender than when connected directly to the router. Strongly recommend, inexpensive and very useful.

1 out of 5 eggsPass it up!

Pros: When it works, it's fine.

Cons: About every 2 weeks it locks you out from the internet. You have to unplug, wait a while and plug it back in. Very frustrating!!!!

3 out of 5 eggsTP Link WA850RE-meh

Pros: Works after initial setup is complete. Price is right. Signal seems consistent. Streaming video works great at 720p. General web browsing and streaming average HD content are very good.

Cons: Slow data transfer. Signal suffers through walls, especially brick walls. Streaming 1080p or higher doesn't seem to offer anything a good AC router can do.

Other Thoughts: I had very good results getting wi-fi signals out to my back porch but when I used it to stream video from my home server and transfer large files it just lagged. Netflix and home media server files that were at 720p worked well, but the 300MB/s transfer was more like 10-20 MB/s when moving larger files (>1GB) or streaming 4k video. My Netgear wireless AC router, even with the physical barrier of walls, worked better when 60-feet or so away.
If you want the fastest transfer rate, or want to stream 4k video, or game hard core, I'd say pay the price and get a range extender made for that. This one is good for what it promises but not much else.

5 out of 5 eggsWorks Very Well if Used Properly

Pros: Does what it is meant to do, in a compact, and stylish hub. Easy set up via WPS and the LED indicators allow for you to easily tweak the locations for optimal connection quality.

Cons: Tweaking the locations for your repeaters may take some time. Its just trial and error. Not really a con as the LED indicators help out quite a bit.

Other Thoughts: It seems many people are not taking into consideration the distances between devices. If you place this on the very edge of your router's connectivity radius, it will not function that well, just like your devices. I have 5 of these repeating off of one router. The closest 2 are about 20 feet from the router, so well within distance. The following 2, about 25ft from the first set of repeaters. And the 5th, about another 25ft from one of the secondary repeaters. You also need to account for interference such as walls, furniture, etc. If you are running into issues, buy a 2nd unit, and halve the distance between the first and the router. It will help.

1 out of 5 eggsWaste of $$$

Pros: GREAT-LOOKING device!
Sleek design w/ pretty LEDs on the front.
Simple, hassle-free setup.

Cons: DOES NOT WORK!!! Router is in an upstairs bedroom closet. I bought this device to extend coverage down into my master bedroom. After pairing with router in the same room upstairs, I noticed signal degradation by over half! Was getting 50-60MBps without extender upstairs, less than 20MBps WITH extender (all within 10ft of the main router). Unplugged the extender, back to 50-60MBps. I moved the extender all over the house in an attempt to locate a stronger signal with no success. Only got 4-5 lights w/ extender < 10ft from router. Anything > 10ft away and the signal on the extender dropped to 2 lights. I've been buying from Newegg for YEARS and have RARELY been disappointed with any products I'd bought. But this one is downright terrible! Even if a product does it's job well HALF the time, I keep it and maybe gift it to someone. But I want my money back on this one.

Other Thoughts: If you're on the fence with this product, DON'T waste your time or coin. I bought this device to extend coverage into my downstairs master bedroom from upstairs bedroom and the signal quality is WORSE with extender connected. Wireless range from router to extender is terrible. Only get two "lights" on extender with any distance > 10ft from the router. I was better off without this device. Would be a waste of $$$ if it only cost $5. Returning for refund ASAP.
