Root Tether via WIFI on unlimited data plans

ladamich · Nov 26, 2012

I have seen a couple of threads about not being able to tether if you are grandfathered into an unlimited data plan. I was tethering pre-ICS using wifi tether for root.

Yeah,

I know. Not working now.

I'm a developer though so I pulled down the source and took a look at what is actually happening. It's really just an edify script with some utilities that bring up a wifi access point using the standard android/linux tools. Our phone needs to use the hostapd utility to create the access point. The problem is that all the pre-defined phones that use hostapd also want to load/unload there own drivers for the wifi chips.

I haven't had time to install the android dev environment yet so I didn't patch up any code. I did however throw together a couple of quick scripts to start and stop tethering using hostapd to see if it would work.

The results - Yes. I can stop and start a wifi access point on my phone. Of course being scripts there is no fancy GUI or anything but it is working. I'm using Rom Toolbox Pro to run the scripts but you can do it from a Terminal Emulator.

So if anybody knows enough about getting to the command line you can give this a try.

You will need the following pre-requisite executables:

iwconfig
ifconfig
hostapd
iptables
dnsmasq
ip

I believe these are included in ICS except for possibly iwconfig and hostapd. If you install wifi tether for root they are included in it though. Wherever you get them from make sure they are in /system/bin so that they are in your path.

You need to have root access to be able to do this. I setup my scripts for everything to work from /data/misc/wifi so you will need to put everything there.

Here are the two scripts plus the hostapd.conf file. Hopefully someone can give these a try. I will try to check back and help anybody I can but my time is limited at the moment.

NOTE - Turn off wifi before running the scripts. You will need to change the ssid name to what you want and also the password to something you want in hostapd.conf.

Good luck!

Scipt to start tethering.

Thanks. I haven't tried this yet but I wanted to say thanks for your contribution. Hopefully Neph is already on this and can give us some feedback.

Yeah, it's working for me. I've been doing this since the ICS release and finally got around to posting here. I thought somebody would patch "wifi tether for root" but that hasn't happened and I have been to busy myself to do it. I guess I could do the patch myself and post it. Once I can find time

Neph81 · Nov 26, 2012

This looks to be much easier then what I was running in to. Does this broadcast a SSID or do you manually need to add one in to connect to the spectrum?

it broadcasts the SSID.

You seem to know your stuff. Maybe you could look at data on cm9 for us and see if you can get that working :-P

I understand you're busy but it sure would be awesome if you could simplify this method for the masses. This method seems pretty straight forward but I know there are many who would love to have an easier method. Thanks again for your contribution

I guess the easiest thing would be to do an svn checkout of the source for wifi tether and add our phone into it. I'll see if I can pull it down. Anybody else is welcome to also. It's here:

I have already install wifi tether. but can't found any iwconfig file from system/bin
Can someone help me? upload it please, thx

If you installed wifi tether it is probably in

/data/data/com.googlecode.android.wifi.tether/bin

Move it over to /system/bin

Download the latest experimental build wifi_tether_v3_3-pre2.apk

Give it a try using the generic ICS wlan0 setup. Make sure to select hostapd for the setup method.

Pull a logcat for me if you can so I can see what is happenning.

I got a screenie of the log but I think you want something else?

Yeah I do but let me know what the screen says anyway.

When I was working on this, I had to replace wpa_supplicant with the old GB binary to get around the wifi tether issues in that screen shot. I could never get it to broadcast an SSID to connect to thou. I was on 3.2-b2 at the time.

Still the same base error I was getting:

I've been digging thru the framework jars and there is a whole section that belongs to tethering. I'm having issues getting it to anything other then .smali , so reading thru it is a pain and I'm not even sure if that is what is causing the issue.

This above log comes from 3.3-b2.

After pasting what files I could find to the data/misc/wifi folder, i got this.

Can someone go over to

Downloads - android-wifi-tether - Wireless Tether for Root Users - Google Project Hosting

Download the latest experimental build wifi_tether_v3_3-pre2.apk

Give it a try using the generic ICS wlan0 setup. Make sure to select hostapd for the setup method.

Pull a logcat for me if you can so I can see what is happenning.

stock ICS using this apk worked for me! Wifi tether apk tested and working.

Working for me too! I am posting this from my laptop wirelessly tethered thru my phone... thank you ladamich!

Edit: BTW, I am currently running Eclipse A3. I will try it again this evening on Icy Fusion 5.2.

mediumrarestea · Nov 28, 2012

Can someone explain what to do after downloading the latest APK? Lost after putting it on SD. Thanks.

reeseboy · Nov 28, 2012

install it, then when you open it up go into settings and change the settings he mentioned -

Still the same base error I was getting:
E/msm8660.hwcomposer( 212): isBypassDoable: Unable to enable bypass due both down-scaling and blending

I've been digging thru the framework jars and there is a whole section that belongs to tethering. I'm having issues getting it to anything other then .smali , so reading thru it is a pain and I'm not even sure if that is what is causing the issue.

This above log comes from 3.3-b2.

You are going to need to reboot to get rid of those errors. Looks like hostapd can't pull enough data from /dev/random for entropy also.

Can you reboot then try this as a hack to see if it allows hostapd to work. You need to be root.

mv /dev/random /dev/random.old
ln -s /dev/urandom /dev/random

Then start the app up and see what happens.

When I was working on this, I had to replace wpa_supplicant with the old GB binary to get around the wifi tether issues in that screen shot. I could never get it to broadcast an SSID to connect to thou. I was on 3.2-b2 at the time.

If you are using hostapd then it shouldn't be using wpa_supplicant.

what problem is caused by those issues with hostapd?

After pasting what files I could find to the data/misc/wifi folder, i got this.

Strange. I think mss clamping was removed from the setup options. Can you uninstall everything and make sure there is nothing left over in /data/mis/wifi and start fresh?

If you mean what Neph81 is seeing it means that the app isn't working at all for him.

Root Tether via WIFI on unlimited data plans
