Honestly, I have only had the TP-Link AC2600 WiFi Extender(RE650) for about 2 weeks. But it performsawesome - solid signals on both 2.4 and 5 GHz bands. Extremely easy to setup, just use the WPS or Log Directly into it. I did both methods just to see how it would go, as I generally never use the WPS (EASY METHOD) of adding devices to my router, I had to go ahead and try it. Went so easy, so easy.But being a bit of a computer, networking nut, I still like doing things the direct hands on way, so directly logged in, very easy to navigate, changed that default security password jazz - DO THIS or anyone who sees these devices or any hooked to your system, will straight off try to log in to them and either hack you or just lock you out.Not to scare anyone, just keep that in mind with ANY electronic devices hooked to your network. Save yourself the heartache.That said, it's so easy to do or have a family member help you, but it is really very easy. read and follow the easy directions and you should not have any problem.My LinkSys Router used to (2yrs ago) delivered a 5 BAR signal to everywhere on my property (about 1/2 acre) but my house is only about 1850 sq-ft. Router sits in the farthest room from screened back porch. As I said, 2 yrs ago the signal was 5 BARS everywhere maybe occasionally at the farthest corner of the property I might dip to 3 but then zoom back up to 5 within seconds.That was 2 yrs ago, more homes have been built, more cell towers etc. So for the last 12 - 15 months, that great signal dropped to 5 BARS occasionally with 2 mostly or completely dropping signal altogether.That's some Big League Taboo nowadays, so that leads me to my purchase of the TP-Link AC2600 WiFi Extender(RE650) - Plugged it in at the opposite end of the house - In the Laundry Room. No problems. Solid Signal on both bands - never drops at all, not even a flicker. Fast transfer speeds, I upload / download photos and graphics to and from my place of work. No hick-ups, no more dropouts, just a solid enjoyable signal. Watch HD and some 4k videos over it without a bit of trouble.This device is top shelf in my opinion. You can set timers for when it shuts off and wakes up (when nobody's home) and can even set the led lights to always on, always off, or at a sleep/wake time.Yeah you can get cheaper, but that's generally a gamble with finding a diamond, usually you get what you pay for. Who needs that headache to save 25 or 50 bucks. Not saying saving some money is a bad thing, I like money too, work hard for it, so throwing it away is not something I do either, but if your internet and network traffic is important to you - why skimp. There may be better too, really just depends on how you use it.If you're a real Rockefeller Type, go for whatever fits your need. I just needed my strong signal and network/internet transmission speeds back to STELLAR.And STELLAR is what this 58 yr old kid got with this TP-Link WIFI Extender. Oh, and it comes with an Ethernet port built into it for direct configuring or getting even more speed out of it. I only used it for the direct login to the device and to upload a new update. That was easy peasy too.Oh, and it has 4 swing up antennas on it. Really nice device, just place it and forget it.Sorry for such a long winded review, but it is an honest one. Like I said, I have only had it for maybe 2-3 weeks, more 2 weeks. Will definitely update if anything happens to change it. FOR NOW IT'S AWESOME AND 5 STARS.Hope this was helpful people.Thanks TP-LINK. Very well done.
