FAQ about this card

->Alfa 500mW USB adapters typically drop the connection about once a day: How to fix?

Alfa 500mW USB adapters are prone to drop the connection about once a day for no apparent reason. Here is the fix in Windows (less than 30 seconds): DROPPED CONNECTION REPAIR Click the Windows wireless icon in your system tray (looks like a PC monitor with radio waves). Click “Support” tab, then “Repair” button. This is not a permanent fix – it will quickly re-connect the adapter the the network.

->Alfa 500mW USB adapter: USB cable with 2 connectors: Reason for second cable-connector

Only older laptops of Win 98 era need to have the second plug connected. Older laptops of Win 98 era must have BOTH of the USB connectors connected to USB ports: One of them for power. Newer laptops of Win 2000 era or younger need only to have the larger of the two plugs connected.

->Alfa 500mW USB adapter: Only one of the USB connectors is required for operation

Alfa 500mW USB adapter just uses one of the USB connectors on the cable: Only the slightly larger of the two USB connectors is required to be plugged in.

Ubiquiti SuperRange Xpress Card Based On Atheros 5006 Chipset,MMCX Antenna,300 mW(5 dbi antenna)

Indoor Antenna Range(150 Mtrs)

External Antenna(1 KM)

Ubiquiti 11a/b/g LONG DISTANCE WIRELESS CARD: This card’s 300mW of transmission (Tx) power is the highest power of any WiFi card available – and this is the only card with 300mW of power in 802.11g mode (as well as 802.11b). This translates into the longest range & highest bandwidth of any WiFi card on earth. This card also operates in 802.11a mode (100mW in the “A” mode, with 54Mbps bandwidth).

Plugs into Express Card Slot:  This is the newer/narrower type of slot.

This card’s long operating range compared to other wireless card models (these are popular 802.11b cards for comparison):

bullet-pt-blue3x the Tx/Rx power of Cisco 350’s 100mW

bullet-pt-blue10x the Tx/Rx power of the following cards which have 30mW: Orinoco Gold & Silver, D-Link, NetGear

bullet-pt-blue12x the Tx/Rx power of LinkSys WPC11, which has 25mW

bullet-pt-blue1.5x the Tx/Rx power of Senao’s 200mW

802.11b compliant (“WiFi”): Compatible with 802.11b, 802.11g, and 802.11a access points


New with CD, in flawless condition.

INTERNAL ANTENNA.  This card has an internal antenna.  The external antenna will improve the range and performance.

ANTENNA JACK: Card has jack (socket/connector) to connect one external antenna.   Jack type is MMCX: You can attach any antenna with an MMCX plug / connector:

EXTERNAL ANTENNA is included: 5dBi antenna clips-on laptop; includes 20-inch (500mm) cable (“pigtail”) with MMCX connector.

Short antenna cables are better, as signal is lost in antenna cables: This antenna has the same net gain as a 7dBi antenna with a 1.5 meter cable.

WINDOWS Vista, XP, 2000, ME, 98SE, NT 4.0, CE: Drivers on CD.  Support for AP mode is available on a separate CD:  Request in email or PayPal note.

    The Ubiquiti SRX works very well with aircrack-ng. I use it with a mag mount omni directional 12dbi with a 1m copper wire. I use the USB-based mag mount GPS sensor (which gives NMEA output) with gpsd. Great for war driving.
