    Economical range extender

    • My Best Buy® MemberMember

    If you are looking for a cheap, reliable range extender and are not a heavy bandwidth user, the TL-WA850RE is for you. Like all of TP-Link's range extenders, the TL-WA850RE is a cinch to configure. Using WPS, it is as simple as pressing a button the router and then pressing the button on the range extender. If WPS is not an option, you can use TP-Link's Tether app for iOS and Android from any mobile device. Out of the box the unit has a nice look to it which blends well with my outlets. I like that TP-Link designed this extender to make sure it doesn't block the second outlet. The LED lights are subtle yet convey everything you need to know including signal strength. This range extender is not dual band, but simply 2.4GHz. What that means is that you will get better range with 2.4GHz than with 5GHz but the speeds are not as high as those offered in the 5GHz band. The TL-WA850RE also has an Ethernet port to allow it to act as a bridge for wired devices. In my usage, I had a consistent signal with adequate speeds one floor up on the opposite side of my house. The extender has been stable, never losing a signal or needing to be rebooted. If this is your price point and speed range, look no further. Otherwise, for a little more money, TP-Link offers dual band range extenders which may be worth the upgrade cost. Submitted as part of a free sample program.

    Performs Well, Reliable and Stable.


    This product is very useful if you have multi-story/big house or office. This is quick and easy to setup. It will increase or boost Wi-Fi signal therefore less or no dead wireless zone. After installing this extender, I am getting good signal in my garage and backyard. Now with the help of it, I am getting coverage in the entire house. I recommended this product to those who have Wi-Fi dead zones. The quick install guide is easy to follow. This extender supports 802.11 n/b/g band (wireless) compatible devices. It does not have support for 5GHz network. It does not work with wireless 802.11 AC band either. I also used this as a bridge and connected device via Ethernet cable, the performance was good. It is not as bulky as traditional extender. I find this device very useful to extend the range of wireless signal. This is also a great alternative to provide wired connection where physical wired connection (RJ45/Ethernet) is unavailable as it can work as a wireless adapter. Submitted as part of a free sample program. Pros: Easy Installation, Compact Design Cons: Not compatible with 802.11AC or 5Ghz band

    The N300 did exactly what it said it would do


    My router had to be placed in one corner of my house. The opposite corner was a dead wifi spot, as was my deck. Rather than a messy, expensive relocation of the router, I thought I'd try an inexpensive solution. The N300 was the lowest cost extender with good ratings, so I ordered one from Best Buy. (It was not available at the retail outlet.) It took a few minutes to set it up. I placed the device in an electrical outlet about halfway between the router and the dead corner. Now I have a fairly strong signal where there was none. FYI - the distance from the router to the N300 is about 25' as is the increased distance of the expanded range (total of 50'). The device is not line-of-sight from the router but it IS within sight of the formerly dead corner. If you have a situation like this, I recommend you give this device a try. For just over $20, it's one of the most cost-effective electronic gizmos ever. (I just installed it last night, so this is only an initial quality review.)

    Easy Setup, Serves Its Purpose


    I needed an extender because I get a really weak signal throughout my second story home; the router is in the den on the other end of the house on the first floor. I wanted the cheapest yet reliable tool and bought this thinking if it didn't work, I could easily return it; low risk. To my delight, it works like a charm. I LOVE the manufacturers of this product because they managed to produce an effective product at a really low price. The setup was very easy (so easy you have to try it to believe it). Where I had to sit near an open door for a weak signal, I'm now streaming my tv shows behind closed doors in comfort. Quality of life improved! Love it and highly recommend!!!

    Not what I had hoped for.


    I got this wifi extender as I live in an apartment building that only has one wifi router and I don't get signal in some parts of my apartment. Since my bedroom was one of those places, it became necessary to get a stronger signal. After the initial setup, my wifi extender worked great! After that first day, I had trouble connecting to it, to the point where I reset and started over from the beginning. After this, the extender worked a bit better, but I still have trouble connecting to this at times. I would be using the internet and have to switch off/on the wifi on my devices to try to reconnect. I often have to unplug the extender and plug back in as well. Most times, I get annoyed and have to move to another and connect to my original wifi network. I've already tried moving this around to different parts of my apartment to see if it's a signal issue, but it doesn't seem to be. All in all, this does work, but it's not as convenient as I'd hoped it would be.

      Thank you for your review and feedback.

      Based on the symptoms described, it sounds like your wireless devices (phone, tablet, laptop, etc.) are having trouble deciding which Wi-Fi signal to choose, since the router and the extender share the same name.

      In this case, we recommend using the extender's "Customize SSID" feature, which allows you to create a separate Wi-Fi name for the extender. Your wireless devices should be able to easily differentiate between the Wi-Fi signals after doing so. You can choose this option during the initial setup process of the extender.

      Our Support Team is always available and happy to help. Please feel free to contact us anytime using the information below, and we'll gladly follow up with you.

    Probably good where no signal at all


    The quick installation guide is written well, however, for option two (non- WPS), it took me quite a few hours of trial and error to finally configure. I had to set the TP-LINK as a fixed IP address in my Link Sys router. I.e. map the TP-LINK's MAC address to a fixed IP address in the router. Until I did that, I was getting constant unable to obtain IP address. I also set it up as a 2nd SSID so I could connect to separately from my router to compare speeds at various places in the house. In every corner of the house, the LinkSys router was quicker on speed tests. Which means my router is sufficiently capable of reaching all areas of the house and still strong enough signal that the single band TP-LINK loses in a speed test comparison. Since this is a single band repeater, it generally means the throughput will be 1/2 the speed of a dual band connection. However, in places where there's zero connectivity, single band beats no connectivity. I'll probably return it and get a dual band repeater.

    Better than Expected

    I had no problem setting this extender up for our wireless IP cameras using our neighbor's 2008 Linksys router, took about 5 minutes max. That router is about 30 feet away and the signal passes through 2 stucco and 2 regular walls. Extender is in an upstairs bedroom and I get a usable signal on my Android tablet on our patio at a distance of about 45 feet. Not sure why another reviewer had problems connecting to a Linksys, with our setup we just kept the same SSID and password for the repeater as the router and it works fine. I guess by now everyone knows that a repeater cuts your throughput in half, but our neighbor has a 20Mbit down and up plan, 10Mbits is plenty fast enough for anything we need. The only negative I can think of is the single port, I needed to buy a network switch to allow us to use our Ooma internet phone and a wired desktop computer. System has been working without a hitch for almost a month.

    Fixed all my Wi-Fi problems!

    • My Best Buy® Elite MemberElite Member

    I have a TP-Link Archer C8 router that will transmit the Wi-Fi signal to my far bedroom but the speed is miserable. Constant buffering on Netflix, slow page loading from my phone, etc. I had some rewards certificates expiring soon so I decided to give this a shot to see if it would increase the speeds and...WOW. This took my speeds from ~22 Mbps to over 65 Mbps and took about 2 minutes to setup via WPS. I was very skeptical of this product since it was only $20 but figured it was worth a shot. Although I've only had it for a day now it's blown all my expectations away. I'll update this review if any problems ever arise but as of now it's working better than anticipated and I couldn't recommend it more!
