With considerable delay due to the workload at Ceata and Tehnoetic, support for ath9k_htc WiFi adapters is now enabled in a modified nonofficial version of Replicant 4.2 (tested with Tehnoetic S2 i9100 and S3 i9300 phones for now). A big thank you to Paul, Replicant lead developer, for answering Tiberiu's technical questions, to our Tehnoetic colleague Florentin for the assistance with testing the WiFi support and of course to our wonderful customers and donor(s).

For using the Tehonetic WiFi in Replicant 4.2, one has to do one of the following:

• build Replicant using Tiberiu's patches in the Tehnoetic repository hosted at git.replicant.us

OR…

• download one of these modified, nonofficial image of Replicant 4.2 prebuilt by Tehnoetic

For S2 i9100:

md5sum replicant-4.2-i9100-nonofficial-tehnoetic.zip
2eda7d1e49dfd299e59ffdb881bc1a17  replicant-4.2-i9100-nonofficial-tehnoetic.zip

For S3 i9300:

md5sum replicant-4.2-i9300-nonofficial-tehnoetic.zip
089e9de83a6e62aad63cf1a0dc37b115  replicant-4.2-i9300-nonofficial-tehnoetic.zip

To have WiFi using this modified nonofficial Replicant version we use command line. The plan was and still is to have full ath9k_htc integration with the GUI, but this proved to involve heavy changes due to the fact the Android Java and C++ code for S2 is written for the way the internal Broadcom chip works. We will do our best to develop GUI integration in newer version of Replicant. Your orders from Tehnoetic and your donations to Tiberiu can help speed up the development.

Tested on Tehnoetic S2 phone and Tehnoetic S2 phone to work with AR9271-based adapters:

• Tehnoetic N150 Mini WiFi adapter
• Tehnoetic N150 High Gain Antenna WiFi adapter

For orders at Tehnoetic, we accept credit card (don't need to log into PayPal), PayPal, Bitcoin and for EU customers, bank transfer too.

To donate, you don't need to have a PayPal account or to log in your PayPal account. You can donate by credit card by clicking on the Continue link at the bottom of the page.

Warning! This modified nonofficial Replicant version is experimental and until this moment we haven't been able to get WiFi working after a reboot without reformatting /data partition. We are not responsible for any loss of your applications and settings you had saved in /data partition. That's why we recommend backing up the /data partition.

First, we recommed you back up your /data partition using `adb pull' or `adb backup'. For installing ADB, see ToolsInstallation at Replicant wiki.

Get root shell with ADB after you connect the phone to your computer in Debugging mode.

adb root
adb shell

Or get root shell using the free Terminal application. Open it and type:

su

Grant the Terminal application the rights to use root.

Insert driver modules in this correct order using insmod.

adb shell
cd /system/lib/modules/
insmod mac80211.ko && insmod ath.ko && insmod ath9k_hw.ko && insmod ath9k_common.ko && insmod ath9k_htc.ko

Inserting these drivers using dependencies with `modprobe ath9k_htc' seems to throw warnings regarding missing symbols, as shown by dmesg. So for now don't use modprobe, use insmod instead.

Extract and copy in the anonical location the free firmware v1.3.1 from the Trisquel package

adb push htc_9271.fw /sdcard/
adb shell
mount -o rw,remount /system # /system fs is read-only 
mkdir /etc/firmware/
cp /sdcard/htc_9271.fw /etc/firmware/
mount -o ro,remount /system

Save the name (SSID) and password of your WPA2 network.

adb shell
nano /data/misc/wifi/wpa_supplicant.conf

Or create the file locally with your favorite editor:

network={
    ssid="My Network Name"
    psk="MyNetworkPassword"
}

and then upload it onto the phone:

adb push wpa_supplicant.conf /data/misc/wifi/

Create this small script file which launches wpa_supplicant and sends a DHCP request to your WiFi router.

adb shell
nano /data/misc/wifi/connect.sh

wpa_supplicant -B -iwlan0 -c/data/misc/wifi/wpa_supplicant.conf
dhcpcd wlan0

Use an OTG cable to connect the Tehnoetic WiFi mini adapter (AR9271-based) to the phone. If you can use a “Y” one or a USB hub to power the adapter from an external current source, that can save you from system crashes that can happen because of potential power consumption spikes.

Use the Terminal application to login as root and run the connect script:

su
bash /data/misc/wifi/connect.sh
dhcpcd[3566]: version 5.5.6 starting
dhcpcd[3566]: wlan0: waiting for carrier
dhcpcd[3566]: wlan0: carrier acquired
dhcpcd[3566]: wlan0: broadcasting for a lease
dhcpcd[3566]: wlan0: offered 192.168.0.104 from 192.168.0.1
dhcpcd[3566]: wlan0: acknowledged 192.168.0.104 from 192.168.0.1
dhcpcd[3566]: wlan0: checking for 192.168.0.104
dhcpcd[3566]: wlan0: leased 192.168.0.104 for 7200 seconds
dhcpcd[3566]: forked to background, chid pid 3624

Test the Internet connection using ping:

ping replicant.us

If replicant.us can't be resolved, ping a public IP:

ping <some-public-IP-here>

If this doesn't work either, then reboot in Recovery mode, wipe user data (format /data partition), reboot again and repeat the steps starting with wpa_supplicant.conf

If pinging an IP address works, but not a domain name, then it means the WiFi router hasn't offered a (working) DNS server, so set one or two:

setprop net.dns1 <some-DNS-IP-you-know>
setprop net.dns2 <some-other-DNS-IP-you-know>

Feel free to add these setprop lines to the connect.sh script.

Long press Power button, select Reboot, and select to reboot to Recovery. Once in recovery mode, use Volume buttons to select “wipe data/factory reset” and confirm “Wipe all user data”. Upon finishing the wiping process, select “reboot system now”.

Formatting /data...
Formatting /cache...
Formatting /sd-ext...
Formatting /sdcard/.android_secure...
Data wipe complete.

The Replicant system will take a lit bit longer to boot up.

We couldn't find a better solution to recover from a system crash and have the WiFi working again. We will try to find one and if you find one before us, please let us know at info@tehnoetic.com.

To have the WiFi working again, start again from the step wpa_supplicant.conf.

Enabling the support in Replicant for the Tehnoetic WiFi (ath9k_htc) took development time. Please consider donating to Tiberiu or order from Tehnoetic as a way to thank you for having WiFi on your Replicant-powered phone and to help the development of support for future external adapters (Bluetooth, GPS, etc).

To order from Tehnoetic, please visit the catalog of products at tehnoetic.com. We accept credit card, PayPal, Bitcoin and for EU customers, bank transfer too.

To donate to Tiberiu, you don't need to have a PayPal account or to log in your PayPal account. You can donate by credit card by clicking on the Continue link at the bottom of the page.

Don't have a PayPal account?
Use your credit card or bank account (where available). _Continue_

Thank you for your donations below and for your Tehnoetic orders!
