    TP-Link AX1800 WiFi 6 Extender Internet Booster
    My home office is one floor below and 30' to the side of our router. Plus, there is a desk, file cabinet and walls between the PC and the router upstairs so my signal was pretty weak. To use this, you have to set it up by plugging into an outlet right near the router and it creates 2 new channels with the same name as you have but tacks on '_EXT' to the ends of the 2 new channels. So you wind up with 4 channels effectively. I then moved the extender to an outlet in the office downstairs which is about 9' from the PC and it found the router again within just about one minute. Then you sign in with the same password to connect your PC, phone or tablet to the '_EXT' channel you want. It worked great and greatly boosted my 2.4ghz and 5G signals to my PC.

    I highly recommend this extender for price, signal and ease of setup.

    I absolutely LOVE this! I had a range extender previous to this one, and it worked well, but it somehow got disconnected quite a while and I had absolutely no idea how to set it back up even though I had the instructions. THIS one has EXCELLENT range and it's so incredibly easy to set up. No more teenagers griping about how poor their connection is. (Don't worry, they will find something else to gripe about)

    4.0 out of 5 stars Extender !!!!!
    Reviewed in the United States on December 9, 2024
    I’m very pleased with the TP-Link AC1900 WiFi Extender (RE550)! It covers up to 2800 sq. ft., and I’ve noticed a significant improvement in my Wi-Fi coverage throughout my home. Setting it up was a bit tricky at first, but once I followed the instructions carefully and got it connected, it worked amazingly. The extender now provides a strong, stable signal even in areas that used to have weak or no coverage. It can support up to 35 devices, which is perfect for my household. Overall, I highly recommend this WiFi extender—it’s a fantastic value for the price!

    We got this product today and it was a fairly easy set up process. We placed this extender in the hallway and it provides coverage to our bedrooms. There’s no more lag when streaming videos from our bedrooms. Good product and would recommend this for people who have similar issues with weak signals.

    I have tried numerous wifi "extenders" over the past 5 years or so, and none of them worked in contrast to the product claims by the manufacturer. I recently upgraded my router to a TP-Link AX21 (AX1800) wifi 6 model. I get great coverage inside my home, but venture outside onto my terrace and its signal could not produce a reliable connection. I was contemplating scrapping the router and going with a mesh router with satellites. But I just bought the router, was happy with it overall and I paid $100 USD for it. Then I began my search anew for an extender that would work with my router. Then I found this little baby for $70 on Amazon. I decided to give it a try, especially given Amazon's liberal return policies. I received the unit quickly and decided to pair it to my TP-Link router via the WPS mode. I plugged it in near my router. Step 1: press the WPS button on the router. Step 2: within 2 minutes, hold the WPS button on the extender for 2 seconds. Step 3: wait up to 2 minutes for pairing to be complete. Well, it worked flawlessly. I moved the extender to an AC outlet next to the door leading outside. I now got full wifi signal outside in either 2.4GHz or 5GHz. Also note, 5 GHz is great unless it is restricted by walls. So in the past, any signal I did receive outside had to be 2.4GHz. Now I can use either, and the connection strength on my iPhone 12 mini is great outside the house. Pages load instantly. YouTube videos stream flawlessly with no stuttering or lost connection. I could't be happier.

    Please note that the AX 21 TP-Link router has a design feature they call One Mesh. This extender also supports One Mesh. So unlike the extenders I have tried in the past, this extender maintains the same router channel name and SSID. So roaming is a seamless experience. I advise anyone looking for a good extender to consider this unit. But research is needed to make sure this extender is compatible with your router. I bought this extender because it specifically states it is One Mesh, and even bears the moniker "AX1800", undoubtedly with reference to my TP-Link AX1800 (AX21). Always choose an extender that allows for maintaining the same router channel name AND SSID. Other routers also have a feature to mesh with their extenders, so start your search there. Hope this helps!

    Product setup in around 5 minutes with no hiccups at all! Extended the range and now all of my tv's and electronics near the back of my office finally work! The easy setup should make this really attractive to less tech inclined people to be able to enjoy seamless internet. Highly recommended!
