====== Tehnoetic WiFi (AR9271) support in Replicant ======
With considerable delay due to the workload at [[https://ceata.org|Ceata]] and [[https://tehnoetic.com|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 [[http://paulk.fr/|Paul]], [[http://replicant.us|Replicant]] lead developer, for answering Tiberiu's technical questions, to our Tehnoetic colleague [[http://florentindimitriu.info/|Florentin]] for the assistance with testing the WiFi support and of course to our wonderful customers and [[#Donate_or_order|donor(s)]].
For using the Tehonetic WiFi in Replicant 4.2, one has to do **one** of the following:
* build Replicant using [[#tehnoetic_wifi_patches|Tiberiu's patches]] in the [[https://git.replicant.us/tehnoetic/kernel_samsung_smdk4412/tree/ath9k_htc|Tehnoetic repository]] hosted at git.replicant.us
**OR...**
* download one of these modified, nonofficial image of Replicant 4.2 prebuilt by Tehnoetic
For [[http://tehnoetic.com/download/replicant-4.2-i9100-nonofficial-tehnoetic.zip| S2 i9100]]:

For [[http://tehnoetic.com/download/replicant-4.2-i9300-nonofficial-tehnoetic.zip| S3 i9300]]:

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 [[https://tehnoetic.com|Tehnoetic]] and your [[#donate_or_order|donations]] to Tiberiu can help speed up the development.
Tested on [[https://tehnoetic.com/tehnoetic-s2-phone-replicant|Tehnoetic S2 phone]] and [[https://tehnoetic.com/tehnoetic-s2-phone-replicant|Tehnoetic S2 phone]] to work with AR9271-based adapters:

* [[https://tehnoetic.com/tet-n150hga|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.

adb root
adb shell
==== Using Terminal ====
Or get root shell using the free Terminal application. Open it and type:
su
Grant the Terminal application the rights to use root.
===== Insert modules =====
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.
===== Copy free firmware =====
Extract and copy in the anonical location the free [[http://packages.trisquel.info/en/belenos/open-ath9k-htc-firmware|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
===== wpa_supplicant.conf =====
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/
===== Connect script =====
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
===== Plug the Tehnoetic WiFi mini adapter =====
Use an OTG cable to connect the [[https://tehnoetic.com/tehnoetic-wireless-adapter-gnu-linux-libre-tet-n150|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.
===== Test the Internet connection =====
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
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
setprop net.dns2
Feel free to add these setprop lines to the connect.sh script.
===== Recover after a system crash =====
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 [[mailto:info@tehnoetic.com|info@tehnoetic.com]].
To have the WiFi working again, start again from the step [[#wpa_supplicant.conf]].
===== Donate or order =====
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 [[https://tehnoetic.com|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?
