If you’re relying on free wifi like one on cafes, malls and your neighbors but you are not getting a good signal then you may want to consider getting a wifi antenna to pickup a much stronger signal. One that I already tried is the ALFA Networks USB WiFi Adaptor (AWUS036H), not sure why they call it adaptor but it looks more of an antenna to me.
Here are the features/specs of ALFA Networks USB WiFi Adaptor (AWUS036H):
4″ + 5dBi Rubber Duck Antenna and 15″ +9dBi Rubber Duck Antenna Included
Realtek 8187L Chipset
Supports 2.4gHz, 802.11b and 802.11g, 13 Channels
Connects at full 54Mbps via USB 2.0
Support 64/128/256bit WEP Encryption, TKIP, WPA,WPA2, 802.11i
Supports Windows, Macintosh, and Linux
Interface USB 2.0, mini USB
I tested on how the antenna affects the connection of the laptop and here are the results, I even tested the connection speed via Speedtest.Net and 2wire.com.
Before I connected the ALFA Networks USB WiFi Adaptor (AWUS036H).
While the ALFA Networks USB WiFi Adaptor (AWUS036H) is connected.
The Speedtest showed different connection speed, however the WiFi signal clearly improved after I connected the ALFA Networks USB WiFi Adaptor (AWUS036H), and I further test the page load and download time and it clearly improved. Of course there are other factors that you need to consider when connected to a Wifi network, like the interference that can greatly affect the connection speed, so I would suggest that you try to minimize the interference to your wifi connection.
The price for the ALFA Networks USB WiFi Adaptor (AWUS036H) is SR 80 to SR 85.00 here in KSA but checking online retailers like Amazon, they’re selling it for $39.95 a box.
