The free firmware is the one packaged by Trisquel and it's linked in this
section:
https://wiki.tehnoetic.com/doku.php?id=tehnoetic_wifi_replicant#copy_free_firmware
However, without the ath9k_htc support in Replicant kernel, there is no
driver to work with that firmware. To be able to build the ath9k_htc free
driver in Replicant's Linux, reverting some older patches was needed, as
detailed in the section:
https://wiki.tehnoetic.com/doku.php?id=tehnoetic_wifi_replicant#tehnoetic_wifi_patches
and committed to the Tehnoetic repository at git.replicant.us:
https://git.replicant.us/tehnoetic/kernel_samsung_smdk4412/tree/ath9k_htc
It takes several hours and about 50GB available space to build Replicant, so
for user's convenience, until these patches are reviewed and merged in the
Replicant code, we provide an image already built by Tehnoetic for the Galaxy
S2.

Using the same patch set we have been able to also build Replicant for Galaxy
S3 and WiFi is more stable there. It seems that S3 hardware can handle better
the power consumption peaks of the ath9k_htc-based WiFi dongles.
We'll soon upload the image for S3 and include Fil's accessibility scripts in
the tutorial (which also work for the S3). As future development, we'll try
to have Tehnoetic WiFi working on the upcoming Replicant 6.0 too.
For convenience, we intend to offer our customers Tehnoetic S2 and Tehnoetic
S3 phones preinstalled with one of the Replicant variants below:
* Replicant 4.2
* Replicant 4.2 w/ Tehnoetic WiFi patches
* Replicant 4.2 w/ Tehnoetic WiFi patches and Fil's scripts
