ALFA Tube-UNA Atheros USB Wi-Fi adapter long range booster for PC or Camp Pro Router


ALFA Tube-UNA is similar to the ALFA Tube-U(N) model that ships inside the ALFA WiFi Camp Pro 2 kit, but it contains the popular Atheros AR9271 chipset instead which contains Atheros Align™ technology designed to increase packet transfer (in layman's terms increase throughput speed).

Like the Tube-U(N), it is 2.4 GHz only and does not work with 5 GHz networks. A dual band option with 5 GHz support is on the way later in 2020. In the meantime this is a low-cost way to get a speed boost and performance increase out of your ALFACamp Pro 2 kit or it can be used directly plugged into a PC. 

This is the retail box package that includes 5m USB cable and driver CD if you wish to use it directly with a Microsoft Windows PC. An antenna is not included. If you are purchasing for direct use with a PC and not an existing Camp Pro 2 system that already has an antenna, we recommend getting this antenna here. This has an N-male antenna connector.

For direct use with a PC, it is compatible with these operating systems:

Microsoft Windows 7, 8, 8.1, 10*

*Use with the ALFA R36A does not require driver install on any computers

*You do need to update your ALFA WiFi Camp Pro 2 to firmware version 1.22 to add support for this device. Click here for firmware image download. Click here for firmware upgrade instructions.

ALFA Camp Pro 2 owners: to upgrade to this Tube-UNA, first upgrade the firmware on your router as outlined above. Then power off your Camp Pro 2, remove the USB cable and antenna from your current ALFA Tube, and use the ALFA Tube-UNA instead. Then power your Camp Pro 2 equipment back on, and go through software setup as normal to pick out the network you want to extend.

This product does not come with an antenna, and does require one to operate. You will need to purchase or already own a compatible antenna to use this. It does not have any type of internal antenna, and indoor use is not recommended.

For indoor 802.11n Wi-Fi with Atheros chip, we recommend ALFA model AWUS036NHA.

This product is an 802.11n standard Wi-Fi adapter with top speeds of 150 mbps.
