A:AnswerYes. It has four high-performance internal antennas to increase range. FastLane3 technology delivers up to 100% performance boost compared to typical extenders by creating a dedicated wireless link to your WiFi.
A:AnswerI don’t think this is the device you need if you aren’t experiencing weak signal strength in certain areas. What this device does is connect wirelessly to your existing wireless access point and boost the signal in the area where it is plugged in. It broadcasts its ID by default as <your exiting wireless access ID> with -EXT appended to the end. I found a nice little overlapping circles diagram on the Netgear support website that illustrates how it helps extend the signal. Hope this helps.
A:AnswerYou could disable "Enable One WiFi Name" option in the setting and set separate SSID to anything you want, but why would you do that? Same SSID as the main router makes connection much easier.
A:AnswerIf you have a wifi booster just outside the gym (I'm assuming adjacent wall) and you're not getting signal in the gym there's probably a different problem. You might be able to completely replace the booster and use the Mesh X4S to give you a decent enough range to provide signal to the gym. Without a visual it's hard to say, but with Best Buy's return policy you can't really go wrong buying one, trying it out, and returning it with the 2 week period, 30 days, 45 days depending on your member status. It has helped to provide a better signal to my Ring Doorbell, and it has to go through an exterior wall, but the distance between the two are about 15 feet so keep that in mind.
A:AnswerIt is based on overlapping signal ranges. If you have a solid wall or other obstructions between the wireless router and the extender, that will affect signal. You will set up next to the router then move the extender to a point where it can still receive the wireless router signal. It plugs into a wall outlet so there will have to be power available at the final location. Even though set up is usually within 5-10 feet of the wireless router, after set up you move it close to the area where you desire coverage. I do not know the range of the extender but went into my backyard just now and detected the signal fairly well at 60 feet from the extender in more or less straight line of sight with only a window pane between me and the extender. It had dropped one bar so it would not do 100 feet in my opinion.
