Price : Too low to display

Replacing your WiFi antenna with This Alfa Antenna will significantly increase the range and strength of your WiFi signal. Our quality built omni-directional antenna is a direct replacement for the antenna that comes standard with your router, access point, VOIP device, or PCI card. Because it is omni-directional, no aiming is equired - it can send and receive WiFi in all directions. This Alfa antenna is stronger then the less powerful booster antennas offered by major manufacturers (Linksys HGA7S and HGA7T.) Installation is very easy - just twist off the factory antenna and twist on our Booster Antenna and you'll experience an instant jump in.

Alfa 9db wifi booster antenna . Works perfectly inside the house and outside, across the street. My original antenna broke after a fall and it had not this range before. Excellent product.

Works well but it's a behemoth... . I got this antenna in hopes of improving the performance of our wireless DSL home network. We have numerous wireless devices that all use our D-Link DSL-2640B modem/router: laptop, desktop, smartphones, and our PS3 streams media from our media server through it. After hooking this up, there was a noticeable improvement across the various devices; nothing is starved for bandwidth anymore. Video is now stutter-free on the PS3. The only problem is...this thing is gigantic compared to the stock one. It's 14 & 3/4 inches long. Our D-Link was quite discreet and out of the way, and now it is most definitely noticeable. The performance is worth it, so it's not a deal-breaker, but I would've liked something a bit more low-key. It's definitely worth the price if you don't mind the large size.

Added one bar . A very low cost way of adding one bar to the wireless signal strength in remote parts of my home.
Simple to install. No issues with this product.

Cons Review

Not for all D-Link Routers . This Item does not work with my DIR-655, buyer beware it will not work with all D-Link routers. Before you purchase make sure its the correct one. The connection on this one was large, almost the size of a coaxial cable that goes into your TV, if the connection on the back of your router is smaller than a tv coax cable this product is not for you.

Signal strength . Using my notebook computer I checked the signal strength in various locations. I would change the antennas at each location. I did not notice any difference in signal strength. Using the original small antenna I would move the computer away from the antenna until it went down to 2 bars. Then I put the large antenna on. It remained 2 bars. If there is a difference it would take a more sensitive measuring device to detect it.

SIMPLY DO NOT WORK . Bad money spent, no change in the signal, it might be better to use steel wool on the original antenna. Bad business

Don't waist your money . This antenna is a waist of your money,,I went back to my old 7DBI.The new DBI Antenna may look like it's the real deal but don't be fooled, I ended up using mine for a perch in my bird cage.

Can't believe it. . Got my mom to stop paying the bill for the wired internet.
It just flat out works, its as if the computer had built in wireless. Set up automatic connection.
I love this.

Ok but not reliable . I purchased this because cost was low and wanted something to increase range. Set up was not that difficult but did have to uninstall and re install twice to get it running properly on Mac OS. Issues I have found troublesome are: it drops the signal frequently and I need to re activate; the USB adapter part fits loosely into the USB connection (which may be the reason for some of the dropped signals but I have been diligent about keeping it secure since noticing this and still there are dropped connections); I am unable to use the other USB port while the device is in because it takes up too much space. However, when it is working I have found significant increased speed and range...I just wish it was a little more predictable.

Awesome! . Works awesome for those older laptops that don't have wifi built in!!!! It is bulky and you do have to be careful when moving the laptop around or you will break it or the port that it is plugged into. Other than that, no complaints...

It was an improvement . It may help a little, the more I use it, I find it more consistently gets me webpages better. But it wasn't a huge improvement.

very good . I had another brand USB Wireless Adapter that was very poor in signal strength, and kept dropping the connection. This one is so much better. The best thing about it is, my wife likes it because it is hidden behind the computer and out of the way. Works great.

AWESOME Wireless Connectivity! . I needed wireless service to a computer in the kitchen. I plugged this in and Windows 7 loaded the drivers and had me connected in seconds. I have an USFF ultra compact Dell GX620 and the antenna brings in a great signal. Wireless N will also receive your G and B signals, if you are configured correctly.

WiFi Hotspot antenna . This is my third one of these awesome products. It enabled me to find free WiFi in the area and I love this product. The packaging does not give a hint of the product name and I found it by doing a massive amount of searching. After I found it the first time, I made the mistake fo thinking I would have an easy time locating it again--not true. I kept the box but it really didn't help much. I wanted a second one for another computer and I ended up doing a whole new search. When the product came, I was surprised that it was the same one that I had ordered previously, but happy. When I broke my original piece going through a doorway, I decided to try to search for it by going to past orders on Amazon. This was easier but it still took some manipulation.

Cons Review

wifi adapter . This worked fine, but the casing fell apart really quick. We were using it on a laptop so it had some exposure. It stuck out a long way and got bumped a lot. The plastic housing did not hold up and we ended up taping it back together till we could reorder the card slot type to replace it.

Loose Connector . The device worked well for about three weeks and then it stopped. The outlet for the antenna did not appeared to be soldered well to the main device and now it is perfectly useless.

Awful documentation - No Linux Drivers . After a lot of messing around with their Windows application (with HORRIBLE documentation, I was able to finally get this to work with the native Windows Wireless Network Connection. This was just in order to be sure it was working in order to get wireless up and running in Linux on the same computer. The description claims that it includes Linux drivers, but none were on the CD. I've spent an entire day trying to get it to work in Linux without any luck. I'm very close to returning this and going back to my old adapter (Trendnet) which doesn't claim to have Linux drivers according to their website, but that's better than this manufacturer with no manufacturer name and no website!
