Review on 2.4GHz 36DBi Outdoor High Gain USB Wi-Fi Range Extender Antenna For RV, Marine & PCs - TUOSHI N4000 by Anil Jaimes

This product definitely works as described. My computer went from seeing absolutely no Wi-Fi to seeing all of my neighbors Wi-Fi. I don't pay for internet but now I am able to use my parents Wi-Fi about 400 ft away. The connection speed is very slow, but it is better than nothing. I have a hard time streaming YouTube videos, but I can download them in the 3gp file format, which is high compression, and still be able to watch my videos. This thing definitely works for the price. I have only had it for about a week. If this thing continues to work, it is definitely worth the price and not buying one of the more expensive $300 ones. In order to save the USB connection, which seems kind of flimsy, I have it plugged into a USB extension and I only unplug and plug in the extension into my laptop, I hardly ever unplug the actual device from the extension. The cable length was just barely long enough for what I needed, if you have this thing mounted outside (I didn't have to in order to see the wifi connections but outside up high gave me better speeds) your computer is going to need to be next to the wall adjacent to the device.One of the other reviews complained that they didn't explain properly how to use this with a router that was also under the same brand. You do not, do not, need to mess with the router at all. This device is an antenna for your computer and has absolutely nothing to do with the router you are trying to use the internet from. On my Windows 10 machine it was plug and play and I did not have to install the software. I would not suggest installing the software, it honestly does not seem all that great. As far as the device working at all it kind of seems like a 50/50 shot, I have four different computers and the device will only work with two of them, I did not use any of the software included with any of the computers.TLDR: this device is at the very least worth a try. I have only had the device for about a week. So far so good. Plug and Play very easy. Hopefully this comment helps, I was skeptical at first but I'm very happy. I will edit this if anything changes.
