AWUS036NHA is most closely related to AWUS036NH because it is an 802.11N device like AWUS036NH.

AWUS036NHA has an Atheros chipset and so it works better with Linux than AWUS036NH, which has a Ralink chipset.

AWUS036NHA does not support Linux driver “directly”.  If AWUS036NHA user wants to use it with Linux, they need to use open source:  Link of discussion of Linux open source driver to use on the AWUS036NHA.

Below are test results froma very technically-savvy customer:   He is testing comparing against the AWUS036H, which is a 802.11G device – and so this is not really conclusive with regard to how the AWUS036NHA performs in 802.11n mode – but it is interesting regarding the performance of the AWUS036NH in 802.11G mode:


The signal strengths I see with the HA are typically not as strong as what I see with the H.  However, this can be misleading since the driver that the manufacturer writes controls this value, and from working on the 8187l driver, I know that it tends to be a bit optimistic.  So this in itself is not really too important.  They both saw about the same networks.  There was some variation at times, with the H tending to see a few more.  Again, this fact alone is not that important however, but consumers tend to like devices that show lots of networks, even if they can’t connect to them J.

I connected both the H and the HA to an Engenius AP so I could monitor the signal level of both devices.  This AP is about ¾ mile from me, and I am using just the standard 5db rubber antenna’s that ship with each unit.

The HA was typically giving a signal strength, on the Engenius AP, of around -78 to -82.  As low as -90db.
The H was typically giving a signal strength, on the Engenius AP, of around -73 to -80.  As low as -88db.

So, the H seemed to have a bit higher output, in this particular test.  But not substantially.

They were both able to connect to the same set of networks where I am currently located, however I need to test this in more locations which will happen as we start to move the boat in 2 weeks.  My current location is pretty limited so I don’t think there is anything conclusive from this yet.
