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 eggsTP Link Range Extender

Pros: Extended router range with a strong signal. Doesn't drop connection at all. Streams Netflix without issue. Reasonably priced for what it does. Super easy setup.

Cons: None

Other Thoughts: I bought this to extend the router range located on the 1st floor of my house to the DVD player in the basement rec room to stream Netflix. Works perfectly without issue. Very easy to setup. This never drops connection, wish I could say the same for my router.

4 out of 5 eggsTP-Link TL-WA850RE

Pros: Easy to setup.

Cons: Had issue with dropped connections as others have stated in reviews. I noticed the manufacturer response of 3/11/15 and tried assigning the range extender a different SSID. Easy to do and it worked great.

Other Thoughts: Cheap solution to spotty coverage in my home. Took care of issue with a smart tv connectivity. Highly recommend this product.

1 out of 5 eggsSales are for a reason...

Pros: -Works when it does

Cons: -Will lose connection at-least once every 24 hours to your AP if the connection is less than 70%, requires a manual reboot of the device or will not reconnect unless the AP reboots before than.

Other Thoughts: yeah, I should've figured, if you keep it in range of at-least 70% it doesn't seem to drop the connection but that's only about 15 feet away from my AP and in the household, it has pretty much made no difference (If anything, more of a headache because the connection is "lost" and all your devices will continue to connect locally to the device without internet causing you to miss notifications and any important data you may sync with your devices.

Manufacturer Response:

Hello Customer,

Thank you for checking out our Range Extender.

We are sorry to see that you are running into some connection issues.

The best place to place the device is where you may get about 3 signal strength bars on the WA850RE - this is to ensure optimal placement.

One thing you may want to try if you haven't already is to make the Range Extender and Router on different SSID's. You can tell the connecting device to connect to the SSID with the best signal so you don't have to have the Range Extender and Router on the same SSID.

Sometimes when both devices are using the same SSID you may run into these types of issues.

Some settings that you may want to change in the Router that may also help is changing the Wireless Channel to a different channel and Wireless Width to 20-MHz for stability.

If you are still running into issues then please feel free to contact our 24 hour technical support team.

We will work with you to help resolve these issues and replace the device if it hapens to be defective.

Best Regards!

2 out of 5 eggsEasy to set up, hard to keep working

Pros: -Set-up was very straightforward.
-Signal strength was good

Cons: -Started dropping internet connections (but keeping WiFi network up) randomly after about 1 week of operation. Despite resets, this behaviour became more and more frequent.

Stopped using after about 6 weeks.

Manufacturer Response:

Hello Customer,

We are sorry to see that you are having some issues with this Range Extender.

Even though we have the one firmware for this device, it may be beneficial to relflash the firmware to help with any possible bugs or issues that may be present:

Another thing to look for is your computer may get a good signal strength from the Range Extender, but your Range Extender may be too far from the Router.

To ensure that your Range Extender is at a good distance from the Router, place the Range Extender into a socket at a distance that gives you three lights on the Range Extenders signal strength indicator.

If you are still having some issues and concerns then you can feel free to contact me directly a

Best Regards!

5 out of 5 eggsEasy Setup, Works Great

Pros: Super easy setup- push a button on your router, push a button on the device, wait a minute, then go plug it in wherever you want it. Seriously. This device radically improved the download speeds in our basement. Movies we were watching buffered 5-10 times per hour. We had not one single instance of buffering after "installing" (plugging in) this device. 10/10 Would plug in again.

Cons: None.

Other Thoughts: Great value for the price, super easy setup for those of us that aren't networking professionals by day.

5 out of 5 eggsEasy Setup + Works Great + Great Price

Pros: Easy Setup, reliable, good range. I live in a 2,800 sq ft single story home. but had some dead spots with my FIOS wifi router. Setup on this was easy just by following the directions. The range is very good, even going through walls. Combine all of the above with a good price and you have a product I am willing to recommend.

Cons: None so far

4 out of 5 eggsIt works

Pros: It finally works for me after couple weeks,after I figure out how to set it up for my situation,it works fine for me.

Cons: Take couple weeks to make it work for me,take one egg off.

Other Thoughts: Have to set up this little thing a different IP address from the base router,when my cellphone is in the weak wifi spot in the house,make sure cell is connecting to this extender not the base router,then it works.

5 out of 5 eggsDoes the job

Pros: Good range through out the house upstairs, downstairs, and decent outside.
Fairly easy setup. It has been great at giving the WIFI the extra umph it needed.

Cons: Lights can be a bit bright especially if they're in a bedroom at night. Easy fix with some masking tape though.

Other Thoughts: I initially had a little bit of trouble with it disconnecting from the main router. The main router was downstairs and I placed the booster upstairs. I moved it downstairs a little closer to the router and everything has been smooth sailing ever since.

2 out of 5 eggsWifi drops

Pros: I had already written a great review about this item, because it worked perfectly when I first set it up. It was easy to set up, and my connection speeds were FAST.

Cons: After a few hours of using this device, I've noticed a few things.
1. Wifi drops when you use the microwave. I know this is a common issue with wireless internet, but I never had this issue with my old repeater- which was half the price!
2. The repeater resets every time you change the wifi channel, and it takes forever to adapt and allow you access to the net again.
3. The device emits a quiet but high-pitched beeping that starts to feel like tinnitus after a while- seriously it makes my ears hurt!

Other Thoughts: All in all, I regret buying this item, if only because the layout of my home causes interference between the router and the repeater. I'm going to give it a few more days, but I'll likely return it for a refund. My old, $15 non-brand repeater worked better.

2 out of 5 eggs

Pros: Very Simple to set up. Works very well (when it works). I put it in a central location and every device in my house saw much higher connection rates. The GUI interface makes it very easy to modify settings.

Cons: Sometimes it works for hours with 6 devices feeding from it at the same time and other times it loses the connection to the base router after 5 minutes and 1 device. When it loses the connection, both machines have to be rebooted. It may be very easy to set up, but who cares if its not reliable.

Other Thoughts: It requires a bit more configuration than you first think and they would have you believe. If your base router does dhcp, you may need to turn it off on the extender. If your base router does MAC filtering you have other problems because individual device MAC addresses are modified when coming through the extender. None of that is a showstopper, but I haven't been able to find the magic recipe to keep it from locking up the base router.

Manufacturer Response:

Hello Customer,

Thank you for your review.

This is a very peculiar issue and it is hard to determine why the Range Extender may be locking up the Router.

One suggestion I have is to set a static IP address on the Range Extender and possibly trying WPA2(AES) for the wireless encryption if you are not already doing so.

If you would like to reach out to me directly then you can email me at

We do have a 24 hour technical support team that you may also contact to assist you and any issues that you may have.

Best Regards!
