By Lincoln TOP 500 REVIEWER on August 25, 2011
Nearly all Amazon.com reviewers agree, the Alfa AWUS036H is the long range WiFi antenna on the market. But with 3 antenna options to chose from, which is the best setup?

I own the all 3 wi-fi antennas from Alpha: 5dBi omni-directional, 7dBi panel, 9dBi omni-directional. The Alfa AWUS036H with the 7dBi antenna is the best performing set up: Alfa AWUS036H Upgraded to 1000mW 1W 802.11b/g High Gain USB Wireless Long-Rang WiFi network Adapter with 5dBi Rubber Antenna and a 7dBi Panel Antenna - for Wardriving & Range Extension *Strongest on the Market*

With the 5dBi omni antenna, I can get 2-3 bars from a public wi-fi signal a little over 1 mile away (direct line of sight).

With the 9dBi omni antenna, I get only 0-1 bar with dropped signals.

With the 7dBi panel antenna, I get 3-4 bars with the fastest data transfer rates.

I have even tested the 5dBi and 7 dBi side by side and the 7dBi loads web pages in less than 1/2 the speed as the 5dBi antenna.

I have done a fair amount of research before purchasing the Alfa AWUS036H unit. The general consensus is that this unit has much better performance for B and G networks than the newer Alfa AWUS036NH model. But for accessing N networks, the newer model is necessary.

Although I still own the 5dBi and 9dBi antennas, I only ever use the 7dBi panel antenan. It's actually shorter in size and easier to transport than the 5dBi model. Go with the 7dBi - you'll get the best performance.

I purchased this item because I live in the country and the cable company refuses me service. I recently purchased a laptop and was able to pick up a weak signal from my neighbor's router (with their permission) so I bought this in hopes of boosting the signal. I immediately went from 1 bar to 3 and sometimes even 4. They are also selling this same adapter with a bigger antenna and I am thinking about trying that one out. I have used this with Vista and XP and it works great with both though I did have to download drivers for Vista off website but it was no big deal. I am a mom and no computer whiz and searched the internet for the best adapter and a decent price and was a little weary about this but it is working great so far.

This gadget is a truly amazing device for picking up WiFi signals from a lot further away than is normally possible. WiFi is a wireless internet connection technology which normally works over a maximum distance of 100 - 200 metres (300 - 600ft). Due to the fact that this device features a much more sensitive aerial receiver, as well as a much stronger transmitter, it greatly extends the distance you can connect to a WiFi hotspot. Most laptops have a built in 50mW WiFi transmitter, so at 500mW this one is 10 times as powerful. With the Alfa, you *might* expect to still be able to connect to WiFi hotspots 2 - 3 km (1 - 2 miles) away, sometimes further. For the process of 'wardriving' (connecting to free WiFi hotspots on your travels), this device would seem ideal.

It connects to your computer using a standard USB cable, which means you can keep your laptop in a convenient location, while clipping the adaptor somewhere where the reception is better - such as next to your window. Assuming that you already have an internet connection, it will automatically find and download it's own drivers (It identifies itself to the computer as a Realtek RTL8187 Wireless Network Adaptor). There are specialist drivers for many different operating systems (Eg. Mac / Linux) available from the Alfa website at [...], and you should definitely consider using one of these drivers if it fails to automatically install.

I work on a cruise ship where the only standard connection is via a satellite, and the internet is correspondingly very expensive. I bought this WiFi extender to see if I could connect to free WiFi hotspots in our ports of call - without leaving the ship!!

I had this booster to increase the receiving signal from one bar to 2-3 bars. It was function as promised. However, something you need to know which does not explicitly explain in the manu. Signal dropped from weak 54MB/s to strong 10MB/s for steadly receivig signal (can not stay with 801.11G and switch to 801,11b speed), second when you use the enclosed software to install proper driver as suggested. My original wireless driver was removed from the laptop without warning. When I tried to use my laptop at other strong signal place without using booster, I could not connect to any wireless access point , and original wireless driver can't be found and need to reinstall original wireless driver again. It took a while to find out why laptop won't work anymore. This is good stuff but it took over the system and install it own with unwant consequence.
