TP-Link AC750 Wifi Range Extender | Up to 750Mbps | Dual Band WiFi Extender, Repeater, Wifi Signal Booster, Access Point| Easy Set-Up | Extends Wifi to Smart Home & Alexa Devices (RE200)

Pro:Does what it says it does. My cable router/modem is upstairs; my downstairs Roku could rarely get a good enough signal from it to be useful. I've positioned the RE200 Extender in probably an even worse spot (near the Roku but on the floor so I can plug the Roku into the RE200 via ethernet cable) and it handles the signal from the upstairs router extremely well. The RE200 also now behaves as a wifi hotspot (which is the main point of the product), allowing our cellphones and other gear to connect downstairs much better than they have ever done. HOWEVER, and this leads to myCon:The initial setup was difficult. The push-button WPS method did not work for me, so I had to set it up via the browser-based utility. Nothing cosmic about that--when it works. It took several tries before I succeeded.Things to remember:1. During Setup, it's important to re-name the network (in other words, don't accept the 'Copy from Main Router/AP' choice). Otherwise, it's far more difficult to troubleshoot where a connection problem lies. I suppose after you get everything figured out and have it working, you can go back and copy your router's name, but I'm going to keep them separate for troubleshooting purposes down the road.2. If, during 'Quick Setup,' at the final step (rebooting), you don't get a message that says "Completed!", **it did not complete!** You will have what looks like a new wifi network, but nothing will be able to connect to it. If you did not get your "Completed!" message, you can manually reboot the RE200 by going to 'System Tools' --> 'Reboot', then press Reboot. You should get your "Completed!" confirmation after that.3. If you're having problems during setup with even getting a simple connection to the RE200 browser page (http://tplinkextender.net/), try setting it up using the ethernet cable as a connection first. Also, if you somehow balled up the 'Quick Setup' and need to do everything again, use the ethernet cable. After you eventually get that sweet "Completed!" message, you can put the Extender wherever you really want it.4. The RE200 comes in 2 flavors as of now (April '15): RE200(US) and RE200(EU). The US version has no firmware updates. The EU version is on its 2nd update. I have no idea how well or not well getting the update for the other region's RE200 would work, but given how much of a point Tplink makes that mismatching firmware and hardware can damage the unit, I wouldn't try it. I was tempted to try the EU firmware, but in the end I got my unit to work just by rebooting from the System Tools menu.5. This replaced a HooToo brand repeater (the Nano) I was using that died after 2 weeks. I'll revisit this review if something goes wrong, but so far so good. And it seems about a 1000 times more solid than the HooToo.6. Finally, I have to reiterate how well this thing works, when you finally get it to work. No deadspots anywhere in the house anymore, and our Roku's now streaming its little heart out the way it's supposed to.If this thing is still working fine in a month, I'll come back and give it that 5th star.EDIT:months later, this thing is still going strong. 5 stars!Last point: the 'Vine Recommendations' are from people who got the product early and for free. After the product has been out for awhile, you should *completely disregard* these early reviews. A review of a free product will almost always be more lenient than from someone who actually shelled money out for the thing.

I installed two of these extenders on my network an extensively tested them using WiFi Explorer (a great app for diagnosing your wireless network). The bottom line is they work pretty well but with a few critical caveats both in terms of speed capacity and setup.On the plus side, I found these extenders to be pretty attractive -- they end up looking like those plug-in air fresheners, certainly less obtrusive than the newer RE210 version with the external antennas. And for the record the only different between these and the newer RE210's (other than appearance) is the 210's have a gigabit Ethernet port where these have a 100mbps Ethernet port. So unless you plan to use the wired port, save money on these.Setup was also easy if you have a newer wifi router that has a WPS button. You just plug one of these into a wall outlet near the main router, hit the WPS button on the main router, hit the WPS button on the RE200 and wait a few minutes until all the lights are solid green. Then unplug it, move it where you want to permanently station it as an extender and wait a minute and you should be good to go. By default it duplicates the main routers network name (SSID) and your various devices should "roam" to the strongest signal as necessary.Here are the caveats:1) The easy WPS setup did not properly setup the 5.0GHz band of my router, only the 2.4GHz. Most wifi routers out now are "dual-band" -- they send separate signals out over both the 2.4GHz band and the 5.0GHz band. The 5.0 is much faster but typically has a shorter range. 2.4 is for older devices or greater distances, but also is more likely to experience interference from a host of other devices that use a similar band, from cordless phones to microwaves. Apple's routers disguise these two bands as one network name (which has both pros and cons) but most routers establish two network names, one for each band.When the WPS setup was done, the RE210 claimed, via its light, to be broadcasting on both the 2.4 and 5.0 bands. But my first clue something wasn't right was that they only duplicated the 2.4 band network name. The WiFi Explorer showed they were broadcasting separately on both bands, but with only the 2.4 name. However, the Explorer also showed they were only bridging/connecting to the main router via the 2.4 band. So what was happening, but it's default setup, is the extenders were receiving signals from both 2.4 and 5.0 devices but down-converting any 5.0 devices to 2.4 when bridging to the main router. Which would result in much slower speeds that you should see for a 5.0 device. This is one of the reasons (but not the only one) that some people complain this slows down their network.I was able to fix this by customizing the setup of the RE210's manually. I used an Ethernet cable attached to my laptop and the Ethernet port of each RE210 (one at a time). Then I opened a browser page to www.tplinkrepeater.net. It asked for a username and password. The default answers for both unless you change them are "admin". From there it was relatively straight forward to see that the connection to the main router's 5.0 band was "disconnected" and to follow the steps to connect it.2) So now I had properly functioning dual-band extenders. But my performance was still far slower than when I was directly-connected to the main router on 5.0. This is because of two reasons. First, the maximum throughout speed capacity of the extenders is only about 1/3 that of my main router. They both use 5.0GHz and "ac" (the latest wifi standard), but the extenders have a lesser capacity. Second, Apple devices (which I primarily use) do a lousy job of "roaming." Roaming is when the device automatically switches from one device broadcasting the same network to another to get a better signal. It's the same way your mobile devices work from cell tower to tower. That's how the network extenders work too (by default*). But using WiFi Explorer I have been able to see that my Apple laptop gets very loyal to an extender even when the signal and speed are far worse than the main router. Windows and Android devices allow pretty discrete user control over how aggressively a device "roams" but Apple likes to keep it simple and not allow a lot of user control so they don't.There is a way around this problem, with a trade-off. You can have the extenders broadcast their own discrete network names (SSID's). If you do this your devices will not automatically roam, you would have to manually device when you are getting a weak signal from the wifi device you are currently connected to tell it to switch to the other one. But this way you could be in full control of staying on the main router as much as possible and only switching in your known deadspots, especially if you give the extenders logical names (for example, if your main router was called "Joe WiFi" you could name your extender networks "Joe WiFi Upstairs" and "Joe WiFi Basement" etc.).The other alternative, which I am seriously considering but haven't tried yet, is the undo all the configuring I described above and intentionally having the extenders only work on the 2.4 network. That way the 2.4 network would roam, but the 5.0 would stick with the main router. If I hit a truly deadspot I would manually switch over to the 2.4 network with the extenders. I have an ancillary motive in this plan, because most of the extenders are for deadspots my kids use -- their rooms, family room, etc. So doing this would have the secondary benefit of keeping the faster 5.0 network as uncongested as possible. Your needs may be different. A hybrid is also possible, I think, where you could roam on 2.4 but have the extenders use a unique network name for the 5.0 band.
