I'm using it to connect to my HOA pool three houses down and across the street. Most of the time it reaches nicely and even let's me access a camera we installed for the HOA to monitor the pool Boosted my regular wireless to reach all parts of 2200 sq feet and to entire front and back yard. Easy setup using my phone. Definitely recomend. This is actually the second extender we have purchased! We needed this for our external camera that was having trouble connecting to our wifi. Once we set this up, we have had no issues since!!!! Just plug it in the room closest to what you’re trying to connect it to inside/outside and you will have more signal!!! Very happy with our purchase! .The instructions could be a little better but by witching a youtube video i got it setup and it works great. From the front of the house where the wireless router is to the back of the house where the office is the wireless access was very spotty. with the WIFI Booster in the middle of the hallway i now get great coverage in the whole house. Review: Easy Setup - Not exactly a tech guy but I had no issues with installation. Instructions supplied were easy to follow and setup was a breeze. Honestly my kids would probably have been even quicker with the install. I say that because navigating their way through their phones and wifi setup is second nature to kids these days. As far as performance goes, it does as advertised. I live in an older home with thick plaster walls and ceilings. Not exactly ideal for wifi. I now receive signal where previously I was unable to, and stronger signal where it was weak. The location and placement of booster can make a difference. So try a couple different locations to see where it may work best for you. Overall, i would definitely recommend this product. The price was reasonable, setup and install was easy and it does what it is supposed to do. what more could you ask for these days. ## Features - [Stable Wifi Extender]: Wifi booster, this strongest wifi extender with lastest dual band technology can provide up to 300Mbps for 2.4GHz, up to 867Mbps for 5Ghz, a total rate of about 1200Mbps maximize your network quality and reduce the loss of data transmission.

I would like to know before I buy.** A: It’s very easy to set up. The instructions that come with the unit are very well written and walk you through the set up. It only took me a few minutes. I used my iPhone for the set up- there’s an app you download, connect to the device to configure it, and then connect to your WiFi network. While I didn't use it, they do offer a phone number for live tech support. The instructions were so good that I didn’t need to call them. The signal is strong and the extender is working great for my application. **Q: Does wireless repeater work at same time as wired ethernet connection?** A: Yes, in fact I have some devices connected with ethernet cable and others o er wifi and it works great. **Q: Is this compatable with t mobile wifi** A: I believe it is compatible with any WiFi. **Q: What are the 2 ethernet ports for? can ethernet cable connect it to any router, not wi-fi signal, for a stable transmission signal?** A: Yes ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great coverage extraordinary awesome *by J***N on June 24, 2023* The range on this extender is great.
