--Commands are basically the same as above, but direct to netd service

[B]HostAP mode[/B] (used by stock tether app/fallback mode)
-/system/bin/hostap (hostap service, init.qcom.rc looks for config /data/hostapd/hostapd.conf)

• You might have to toggle stuff on and off once first if you run into errors. I think there's an error on first creation of config
• If you switch modes between native wifitether and fallback mode (or stock tethering), your phone may spontaneously combust(wifi crashes) after the routing mess that ensues. Just reboot and you'll be all set again.
• Seems to work better on SuperSU - Probably due to the per-app permissions vs per command.

Try to merge together what worked for everyone across different devices. There are 2 options in settings with mild enhancements
-Wifi-Driver Reload - Driver reload inside of tether script. Similar to 11/20 version
-Wifi-Driver Reload 2 - Driver reload outside of tether script. Similar to 11/18 version

Please report in with Carrier/Device and what option works best for you. Valid combinations are no reloads checked or one of the reload methods. Do not check both (theres no code to stop you from doing it now)
There is no code differences between the two apk versions, I just recently added in reload method 2 so rom devs can cook in whatever apk just works without changing settings.

Apparently I botched code along the line somewhere between 18-20. Please let me know which one of these versions you are on and what works.

WifiTether_TrevE_Mod_11_20_2012_insmodv3.apk - If v2 doesnt work this should - http://www.androidfilehost.com/?fid=9390169635556426691
If insmod v2 doesnt work, insmod v3 switches to insmod on load, rrmod to unload, then reloads the driver when finished with with mfgloader -u / mfgloader -l

WifiTether_TrevE_Mod_11_20_2012_insmodv2.apk - Hopefully working- http://www.androidfilehost.com/?fid=9390169635556426686
Driver Reload did not like loading with mfgloader in original build. This switches to insmod on load, mfgloader/rrmod to unload, then reloads the driver when finished with mfgloader -u / mfgloader -l

WifiTether_TrevE_Mod_11_20_2012.apk - Broken - Thanks halmo20 for catching that

GS3/E3D driver load/unload methods cleaned up, wifi driver reload checkbox should now be used, it was forced previously in code.

NetDndc Max client mode ported down to netd as well. Setting enables/disables with netd
all superuser code removed outside of tether binary, should have less popups for non-supersu users
Framework tether mode moved to setup
Fixed settings being applied reverting user settings at first start
All Cyanogen hostapd binary leftovers removed
Busybox check removed

Bam - Symlinks gone by default thanks joshbeach for all testing
New option Netdndc Max mode, this should be devices default setting.
Encryption works starting this build with netdndc max mode


WifiTether-TrevE_Mod_11-17-2012.apk - http://www.androidfilehost.com/?fid=9390188424645836869

cut down symlinks to only move hostapd around.
Made a checkbox that controls symlink code. Trying to axe it all. Moved this and fallback to settings screen. now save/load
define wifi.interface where it is undefined like on t0ltespr (hack to wire it to ndc settngs)
try to work with t0ltespr's /lib/ directory
cut down root code significantly (hopefully spam/timing issues resolved)

WifiTether_TrevE_Mod_11_15_12.apk -
Code cleanup
e3d code driver reload mess moved
samsung symlink mess in separate class, hoping to ditch this all soon
fallback mode in separate class, wired up to wifitether settings (encryption should work)

• Phone takes back control of wifi- Youll notice a "What the hell" toast message. Somehow the phone moved wifi state, either you toggled an app that turns on wifi or some system process was thinking for you. Disable whatever is doing it.

• XXXX still doesnt work - First try SuperSU. This will avoid a lot of headaches. Then make sure you are on latest version and that you have uninstalled/cleared app data when you went to a newer version. Read over the last few pages of thread at least too to make sure its not a known issue then go for it and post away. Make sure you include Carrier / Device / Rom / SU application.
