The Android WiFi Tether app does work with temp root. Unfortunately right now infrastructure mode does not work. Here’s what you need to do.
1.) Use version 3.1 Beta 7
2.) Change the setup method to WEXT (ad-hoc). Use the “Default” device profile or any other profile that will let you use this setup method
3.) Do not use WiFi-Encryption – For now this doe not work. You must use Access Control if you want to restrict access.
4.) Enable “MSS clamping” and “Routing fix”
5.) Tether away.
