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.

5 out of 5 eggs

Pros: easy to install and works great

Cons: no con's does exactly what I need

Did you find this review helpful? Yes No

5 out of 5 eggsWorks well

Pros: It does the job of Wi-Fi extending well for the price without any complaints.

The blue lights are different, but kind of nice too.

Cons: Kind of wish the plug base stuck out a little bit in order to not crowd other nearby plugs too much (I use cheater plugs in order to accomplish this when needed when ground isn't required).

The reset button would also be nice to have pressable without a pin or other small object (but this shouldn't really be an issue after the extender is set-up; only a minor inconvenience if you happen to mess up or want to redo the initial setup or want to reset it later on).

Other Thoughts: A Linksys EA6700 couldn't push wireless far enough through my house to reach a room above the router, so I'm using this extender in another downstairs room, right underneath the room wireless needs to go to. This extender does the job of allowing wireless to that room wonderfully along with extending it outside a bit too.

4 out of 5 eggs854RE with Ethernet Jack!

Pros: Easy setup
Reliable, have not had to restart it. Have a 854RE as well and that is still going, no issues since I got it almost 6 months ago.
Ethernet Jack
On sale currently, making this one a better value than the 854RE, especially for those wanting an ethernet jack.
Small and simple.
Great for mobile devices, allowing you to not worry about your connection anywhere in your house.
Also works as a work-around for devices with ethernet jack, but can't have a wifi card installed, allowing you to bring those previously unconnectable devices online.

Cons: Flashy blue light, keep this out of your bedroom or where you sleep. I have mine in the kitchen. Allows me to reach wifi from my car.
No other cons I can think of, it meets expectations and does its job without complaint.

Other Thoughts: I previously reviewed the 854RE and the only thing I would have liked it to have was an ethernet jack.

5 out of 5 eggsDecent Range Extender

Pros: Small portable and unobtrusive. Plugs neatly in the wall without the need of a big clunky AC adapter.

Works with all 2.4 Ghz b/g/n networks and boosts range to approximately same length of most routers. Encryption pass through such as 64/128/152-bit WEP, WPA, and WPA 2.

Ethernet port is a nice add on to connect wired devices and also functions a wired bridge as well.

Blue smart signal indicator light is conspicuous and easy to read to find out signal strength and speed.

Very installation overall. You can set it up two ways, first by using the WPS button and second by connecting it to a pc via ethernet. I used the WPS button and the device connected seamlessly; took roughly about a minute. My router is located in my basement so this device was easy to test. I tested the wi-fi signal in my attic using a laptop with the range extended set up on the main floor. Encryption was fine so was speed and most of all the signal was boosted from 3 bars to a full 5 bars and remained steady while connected. Unfortunately this is for only a 2.4 Ghz signal and I was not able to test for 5 Ghz. No disconnections whatsoever during testing as well.

Cons: Unfortunately the device is limited in it's wireless capabilities. I currently have the Verizon Fios Gateway AC router set up so I could not test my 5 Ghz AC signal. Wish the range extended at least had support for 5 Ghz since these signals have poor surface penetration and decreased range.

Other Thoughts: A very solid range extender. Simple, easy to setup and very good for those looking for a no hassle solution to extend your current wi-fi signal. As mentioned above in cons, I wish there were support for 5 Ghz and 802.11 AC but the specs justify the price point for this device and it is most likely made as an entry level range extender. Works well for the price and specs; TP-Link did a good job with this range extendeder and I would definitely recommend this for anyone looking for a range solution

5 out of 5 eggsNice Cheep Option

Pros: Great Option for the Novice to extend there network with.

Small cable included, Instructions as well as a full PDF on disk.

Speed is greatly increased using the LAN cable with no wireless devices connected (if using a wireless device it must connect to the dive, then to the network, then to the device again, this cuts down the speed)

If only browsing the web, or sharing Video / Audio this device will be perfect.

Speeds I was achieving were to be as expected for a device of this type, nothing great, but very usable.

Great price.

Cons: Can not run a LAN cable to it to extend the network even further.

Not a device you would want to use for transferring LARGE files, or playing games over as it has very high latency due to it's type of connection.

Other Thoughts: Another great product from TP-Link, as usual it is fully functional and at a great price.

As noted above this device uses a dual communication method that must communicate with your device and the network individually and this cuts the speed in half, and doubles your Latency. If you need a faster connection over a long distance you are going to be spending a lot more than this.

4 out of 5 eggsDecent unit

Pros: Put in CD read basics for automatic setup and connected to my router no problem using the WPS buttons to establish the connection then did it manually and completed the initial setup then moved it to the farthest room in house that only gets 3 out of 5 bars connection and now have a 5 bar connection signal. Tested speed with the extender and our normal speeds are in the 30Mbps range and with extender give up some speed to about 23Mbps range, but with a more reliable connection so it is worth the minor loss of speed in my opinion. Then tested the unit in a few other locations around the house and got similar results as the first room but did notice the closer I was to the router the faster my connection speed but never got to full speed, so distance does have an effect on it which I expected. The unit is simple design that blends itself in to the room décor The indicator lights are not too bright. Used Ethernet port to connect to the laptop and it also worked properly no problems noted. Security seems to be decent with the unit and easy to setup, better than one of the other units I tested by same company. This unit has an advantage over the WA854RE in that it has an available Ethernet port. It does include a short Ethernet cable in the box for units that do not have WIFI. Cost is very reasonable and the unit works so very happy with the results and can recommend to those that need WIFI in a far reaching room or maybe a built on garage.

Cons: Slight loss of speed but as I said it is a minor thing not a deal breaker.

4 out of 5 eggsGood for a casual "surfing" in a small area.

Pros: - Will extend the range of a 2.4GHz n/g/b wifi network, but not by much
- Ethernet port on the device so it can act as a wifi bridge
- LED signal strength meter on the front of the devices to show you how strong a signal it is getting
- Pass through WEP, WPA and WPA2 encryption from the router
- Can be setup two ways: WPS button on unit then router or by connecting a PC to its ethernet port ans accessing its web-based GUI settings

Cons: - Single band only (supports only 2.4GHz wifi n,g,b)
- Only has two antennae
- Range isn't great
- Depending on which power outlet you connect it to, it could block the other outlet
- Using range extenders / repeaters cuts router's throughput in half

Other Thoughts: I tried this unit out for a few days and wasn't impressed. Yes it did extend the range of my old 2.4GHz N network, but not by much. Where as the signal from my old N router stopped right in front of the den (no signal in the following room or the room after that), using this extender only bumped it up into the next room. The room after that still didn't get any coverage.

The unit is "awkward" and bulky. It won't block the port beneath it if you plug it into the top outlet, but if you for some reason plug it into the bottom outlet, you lose use of the top outlet.

I can't knock of too much though since it is cheap and it does perform its advertised function.

Overall, I do not recommend using range extenders since whatever connects to the wifi signal coming off of the extender, will only be getting some fraction of the actual throughput from the router.

5 out of 5 eggsGood For What It Is

Pros: The first thing I'm going to say is THANK YOU TP-LINK for including an ethernet cable! You don't know how many inexpensive networking products I open that don't come with a network cable. They are pennies to include, and it frustrates me when they aren't included and I need one.

Ok, now for the product itself. It works, I was able to plug it into an outlet in my garage, configure it with my laptop and then walk out into my driveway and get a single and browse the internet. My driveway previous had either an extremely weak or non-existent signal before, depending on conditions. Now, my driveway is covered with a nice reliable signal. This sounds like kind of an odd scenario, but it is actually a solution I use. The driveways in my neighborhood turn into hangouts on the weekends. Everyone drags their grills and chairs out and we all just kind of move from driveway to driveway around the neighborhood chatting and having fun.

Setup was super easy though the LAN port, and I also was able to configure it through wireless when I had to change some settings.

Lets get down to some numbers on throughput. When standing in my driveway, when I was able to connect to my access point in the house, my speed was only 3Mbps download, and it was extremely spotty. At one point I though the speed test had frozen, but it was just sitting there waiting. With the repeater in my garage, standing in the same spot in my driveway I get 23Mbps. That is a very big and noticeable improvement. When I'm in my house though, connected directly to my access point I get 47Mbps. So the speed through the repeater is about half of the full speed, but it is still way better than nothing.

Finally, the LAN port on this is such a nice addition. I have a media center PC in my garage that I use to play movies and such. It was previous connected with a USB Wireless G adapter. I was able to plug the PC into this extender and use the extender as a wireless adapter. It worked wonderfully. And I actually got 64Mbps download speed doing this while the previous Wireless G adapter was only getting 13Mbps. I can now actually watch HD content!

Cons: No external antennas. it seems like it performs Ok without them, but I'd like to see them and I think it would perform a little better with them.

The one thing during setup that I wish was different was I wish it prompted me to change the login password. At the end of the configuration it gives you a setup summary, and it lists the username and password, but never has you change them from the defaults. I had to go back into the configuration and change them after the initial setup wizard was complete.

The biggest con is that this doesn't support the 5GHz band, it is only 2.4GHz. I know adding dual band support costs more, but I really think extenders can benefit from simultaneous dual-band support. The main benefit being that you can connect to you main access point on the 5GHz band, then use the 2.4GHz band as the extension. This would eliminate the half duplex issue that causes the speed to be effectively halved. However, on a sub-$30 device, I can't really expect dual-band support like this.

I took one egg off of my TL-WA854RE review because that adapter didn't have a LAN port. This one does, so it gets full 5 eggs. This adapter, IMO, makes the TL-WA854RE a redundant product. Even if it is a few bucks cheaper, I wouldn't buy a WA854RE, I'd buy the WA850RE with the LAN port.

Other Thoughts: For the inexpensive repeater that this is, it does its job. If you need to extend WiFi to an area that doesn't have it, this will do that. If you just need a reliable connection, and not necessarily the fastest, this will do just fine. I would even say it would work with 2-3 phones/tablets/computers streaming data at the same time. I wouldn't go much more than that though. However, it will support more than that if just browsing and checking email is the goal.

5 out of 5 eggsYou get what you pay for

Pros: • Good performance at this price point.
• Simple as pie to install and configure.
• Did a decent job extending my wireless signal into a 2nd-floor corner room with an otherwise non-existent signal.
• LED status lights are a nice, informative touch. They are a bit bright, however.
• Works with my NETGEAR R8000-100NAS Nighthawk X6 AC3200 Tri-Band Gigabit Wireless Router.

Cons: • Doesn't push the signal out real far, just enough to get you some useable internet in an otherwise distant area.
• LAN port isn't gigabit (come on guys, it's 2015 already).
• Only b/g/n - no AC support.
• Half duplex, so it can only send or receive at any given time, not both. This means your usable speed will be cut in half at best.

Other Thoughts: • Summing up - as far as my house goes, it did what I expected it to do at this price point. Was it "wow this is amazing" - no! Was it, "OK, it does the basic job I want" - yes. I'd suggest doing a CTRL-F on the Newegg reviews for your particular router make or model to see what opinions others may have of a setup similar to yours.
• If you're looking (like I was) to extend a signal into a room that couldn't otherwise get enough of a signal for internet browsing, then this will work for you. I don't think you'll be streaming 1080p video into an otherwise distant area, but it'll get you online with usable internet-browsing speeds.
• While this supports WPS for easy Wi-Fi setup, I recommend disabling WPS on your home network for security purposes (depending on your actual physical environment). Feel free to do an internet search on WPS security for further info.

4 out of 5 eggsCost Efficient Repeater/Wireless Bridge

Pros: This is a good and inexpensive wifi repeater which can also function as a wireless adapter at a fraction of the price of dedicated console wifi adapters.

This model is one step up from the TL-WA854RE and differs from it primarily in that it has an ethernet jack and can function as a wireless bridge. TP-Link's top of the line model is the RE200 dual band with AC protocol.

Getting reliable wifi throughout a space is not easy, particularly with 5GHz having such short range and the 2.4 GHz band being so crowded. Some homes and offices are not easy to wire up.

There are three ways of extending your wireless network into an area where you have marginal coverage. 1) Run an ethernet cable from your router to a new wireless access point (the best). 2) Hook a powerline adapter to a new wireless access point (less good). (TP-Link has a very cool combination powerline adapter/access point combination - see the TL-WPA4220Kit), 3) Run a wireless repeater (the worst). For the technical aspects, gotchas, and limitations, see other thoughts.

As wireless repeaters go, this one is inexpensive, easy to set up (WPS button), small, plugs directly into an outlet, comes from a good company, looks good, and works pretty well as long as you know the limitations and gotchas. As long as it is close-enough to your main wireless access point to get a good 2.4 GHz signal, it will repeat the 2.4 GHz signal for you. I got up to about 70 feet line-of-sight range extension. It has internal antennas, seems to run an Atheros CPU, and I got about 20/25 Mbps down/up speed just like the TL-WA854RE model. This compares favorably to other 2.4 GHz repeaters I’ve tried (Netgear, Linksys, Edmax).

Cons: This device does not have any cons specific to it except that wireless repeaters are the last-choice way of extending a wireless network. It compares favorably with other 2.4GHz repeaters but has a shorter range than those with external antennas. Positioning is limited to power-outlet location since it plugs directly into a power outlet.

Other Thoughts: There are some gotchas with all wireless repeaters. First, they slow down the bandwidth by at least 50% since they are repeating/re-broadcasting the signal. Second, the repeater has to be placed where it has a good connection to the parent wireless access point. Mapping of your wireless strength and channel availability in a potential placement location can be done with many cell-phone apps these days, though. This unit has a 5-level signal strength connection indicator to help place it correctly. Third, this unit operates on the more-common 2.4 GHz band which is more crowded than the newer AC protocol on 5 GHz.

Before you go with a repeater, first try moving your root access point or getting a more powerful access point or bigger antennas.

(In the past, I've used powerline adapters to hook up an access point I couldn't wire in. I thought it would be cool if someone made a combination powerline/access point unit and it turns out TPLink has just such an item at less than twice the price of this repeater.)

If you need to cover a 20-30 foot dead spot for “consumer internet” type speeds this Range Extender might do it for you quite inexpensively. If you need to run many devices and do big file streaming within your local network, you’re gonna have to run wire.
