Question: After it's all installed, does it still have to be connected physically via cable to usb port on laptop?  Or can it be disconnected and function wirelessly?
Document: I was apprehensive about this product. It seemed to me that the claims were most likely exaggerated.They are not. I took my laptop 200 feet away from the router. The laptop did not see any wifi signals. I plugged the power king in. Windows 7 installed the usb driver and low and behold. 8 different wifi locations showed up. I connected to my router with 5 bars.A+++. Great product.
Fantastic. I plugged this into a Windows 8 PC. In a few minutes, it had connected via my weak wifi signal and installed the drivers. After the drivers were installed, I could see 10 (ten) other networks in my neighborhood, including my neighbor's, four houses away. The computer I use this with is on the second floor of my house. The wifi signal comes from the basement. Prior to installing this magical device, I could get one bar, maybe two, on my computer.
I have used multiple antennas over the years and this one is superior. Highest strength, speed, and reliability. I have been using this for months with no problems.Pros:  Easy install. Simply plug it into your usb port.Install the newest drivers by going to the website  [...]Ralink3070 drivers then reboot your computer. Double Click on the R in your tray in your menu.
Delivers on every point 100 percent, easy setup basically plug into a usb port and enjoy stronger wifi signals instantly. Does exactly what I wanted with nothing added. would buy again  arrived in mint condition , it should be noted that delivery is a bit long due to them using regular mail but it saves on shipping as I wasn't in a hugh hurry that really didn't matter to me. Customer service is also responsive and fast nice company and product would definitely recommend to anyone who needs a wi fi signal boost
Saw just a few more signals but wasn't able to access any. Original signals were not any stronger than the ones I already see on my laptop via wifi card. Tried different areas in house with no better results... Bought this based all on positive revues here. Am I doing something wrong?
If you over stress that connection it will snap the USB port right off. But under normal use this has not been a problem, just when the unit is not set on a stable base and the USB cable is the stress point. Had one of the units hinge freeze up, guess the ball baring and spring loaded hinge &#34;bite&#34; into the plastic a little hard. I freed it up with a small blast of silicon lubricant and it moved freely after that.
This is a very nice adapter. It loses one star because the documentation and the driver disk were very poorly done. The driver on the enclosed disk did not work and I had to go to two sites before I could find one that actually worked. The other disk is a linux disk meant to help one crack other networks. In terms of function, the Adapter works very well once installed.
I had this thing since November, '13 and it still fusses as me. The documentation - think BASIC INSTRUCTIONS  are horrible and tech support is apparently limited to script readers whose knowledge is far less than ours. Even the product description is lacking technical details as to purpose and intended function. Far too late for me to return it; I'll try to find some use, but I'm not encouraged. The install and recognition routine seems to require some 'card,' not resident here, to govern this antenna's functions.
Yeah, it's cheap  plastic, very light, and easily comes tumbling if you tug on the usb cable accidentally. But it really improves yourwifi connection. It turns a &#34;low&#34; rating into &#34;very good,&#34; and a &#34;good&#34; rating into &#34;Excellent.&#34; Has really made a difference in my life.I also ordered the Etekcity AR5 antenna/adaptor.
thought it was getting sent back but usps figured out the issue received item late but was my fault clearly received item well packed opening item as I type this first thing side ant are non removable, the usb cable long and thick, in the box you get small cd and a larger one surprise it comes with a disk called pin, looks like a  version of reaver.
Answer: This is a USB powered range extender that replaces your internal WiFi internet card. I recommend when using the Signal King range extender to turn off your internal card so there is less wireless interference in close proximity to the external range extender. Since both devices run on a 2.4GHz they can jam each other causing reduction in performance and range. I have experimented with leaving the wireless card on in my laptop and checking the speed of loading web pages and what not. I have seen at times a reduction in speed while the internal wireless card was on while using the the external range extender.
