* Installation pretty easy, does the job at 5Ghz, improving laptop connectivity from 1 to 10 mpbs, to 125+ mbps.
* Uses "one SSID name" and smart connect which makes transitioning between router to extender connections transparent, and connect to strongest available single.
* This "tri-band" connector does not connect at all in the 2.4 Ghz band.
* Only supports one of two 5Ghz bands. What's "tri band" about this extender?!
* Android phone (T-Mobile, Samsung S6) connects and shows mega MBPS (>100, sometimes >400), but it still drops calls, cannot send/receive text, and says "no carrier". Something about the ext signal is incompatible with the android wifi adapter signal.
* Customer support is non-existent (off-shore, ESL foreign nationals, who apparently have never actually seen, used, or configured the device they are trying to support. Netgear has serious problems with this product, but they'll never know it, because their tech support is not competent enough to understand the problem, let along help the consumer solve it, or escalate it to higher tiers of support.
I bought this Netgear extender because my Netgear Nighthawk R7900 router though robust, was about 18 months old, and the signal no longer successfully reach my desk/laptop on the second story, about 60 feet from the router. This extender (EXT7500) was advertised as covering a 2000 sq foot house. The extender was properly sync'd and configured at the router, then moved to it's permanent installation site which is upstairs, and virtually over the router itself (maybe 5 feet away. There are walls and ceilings between the router and extender, but basically they are all drywall and studs, nothing like concrete or metal that could block the single. As a result, the signal between router and extender is very strong, and all lights are showing blue. I initially tried moving the extender 10 feet further (maybe 15 feet away, and up the second story 3-4 feet, but the 5Ghz was showing amber. So much for this extenders advertised range.
However, in the location installed, second floor, above the router, the extender appears to work well. My laptop which was showing 2-12 MBPS connectivity, now shows > 100MBPS (by comparison, the laptop hard wired to the cable modem gets about 230 MBPS, and maybe 170MBPS off a port on the WIFI R7900 router. So, basically, in 5Ghz mode, we're good to go, and the laptop does well.
However, the main reason I bought this was that my android phone could no longer perform WIFI calling or send/receive text messages, unless I was standing within a couple feet of the router. With the extender, my phone goes form the same 2-20 MBPS connectivity, to >100, sometimes >400 MBPS, which is I am certain, reflecting the signal from phone to router via the extender (not the actual internet speed). So, that looks great, as well. However, the phone must be connected for a period of time, maybe 10 to 30 minutes, before the signal stabilizes enough to carry a phone call or text. For a truly "mobile device", this is a real problem. I couldn't even call customer support because my phone kept dropping the calls, while connected at > 100 MBPS.
And, there is no way to effectively get support for this product. I am a technical person, i.e. I work on Oracle software and configure servers, devices, and build networks for a living. However, the tech support person (three different people) really knows nothing about this product. The last person was trying to explain to me that my laptop was incompatible with the Netgear device. I explained to HER that the laptop compatibility would not be the issue, but the laptop's ADAPTER could be the issue, as well as the adapter's drivers. My adapter is an Intel Dual Band Wireless AC 7260, which is the "Boeing 737" gold standard, i.e. one of the more widely used adapters on the market. There is nothing wrong with my adapter. It connects well with Netgears R7900 Router, as well as many other WIFI routers that this laptop has connected to.
Your experience may vary. Different android versions, Apple IOS, different mobile devices with different adapters may work better for you.
My choice is probably returning the extender, and just replacing my Netgear router (i.e. they always seem to die afer about about 18 months of use, regardless whether they're used in a hot attack or frozen basement, conditions do not matter, they just go south). The extender does really work amazingly well at extending my Netgear router's useful life span. However, I'm really only sitting at most, 50-60 feet from the router, and about 20 feet from the extender. It's not as though the conditions at my site are a major challenge for the advertised capabilities of this extender. 2000 sq ft? Not unless you're standing in the middle of an empty, 2000 sq foot warehouse floor.
Chances are, it'll work well for you. If it doesn't, return it because you're screwed trying to get competent support. (You'll waste hours on the phone.) Again, I'm a technical professional, and there is no question about the configuration of this EX7500 or my Netgear R7900 router. The problem is in the limitations of the device itself.
