Wifi Tether Phone to Phone?

Is it possible to tether one G1 (with a data plan) to another G1 (without a data plan) ?
I did search but it's hard finding results with common keywords such as "wifi tether phone to phone" or such.
Thanks,
Rick

I would imagine you could accomplish this with root on the phone with the data plan and have an adhoc wifi app running. Then connect the non-data plan phone via wifi to the data phone and it may work.

you can use the infastructure mode to accomplish this with root on the data phone using the tether binaries (you have to start it manually or manually edit the tiwlan.ini) search a couple of my posts and you will see what you need to change.

neoobs,
Thanks for the direction..
I did..
adb pull /system/etc/wifi/tiwlan.ini c:\AdbWin\tiwlan.ini
but the setting is already..
WiFiAdhoc = 0
Am I missing something?
Rick

First I need to know which version you are isntalling... a link to a thread or even a download. Or if there is a read me let me know that too

I installed Wifi Tether for Root v0.9.5 on my rooted G1, HTC Magic RC33
In one post you stated that WiFiAdhoc need to be set from "1" to "0". My WiFiAdhoc is already set to 0.
My laptop tethers perfectly with my G1, but I would like to allow a second G1 to tether too. I think that the second G1 refuses to see an AdHoc network.
Rick

If I remember correctly you can't use this on the Magic firmware. And apparently I have a special phone that can do the impossible

ok, well.. wanna trade phones?
I see the other thread so I will wait and see what happens with future development.
Rick

Haven't tested this on v 0.9.6, but on 0.9.5 wifi teather for root users. I teather to my roommates stock iphone. I know its a little different, but if his iphone can do it, surely our phones can. I'm sorry I cant be more help, just wanted to throw that info out there
Edit: just read the magic part. For reference I'm running jf rc33

as long as the g1 can adhoc i think you can just setup one g1 to tether then connect to it via wifi. this shuld give wifi to anything that has adhoc wifi abilities..right?

A cry for help!!!

I want to ask anyone with better knowledge of the android os for help.
I need to be able to connect to ADHOC networks. I have a laptop with LAN internet connection and I want to connect my G1 to the laptop's wi-fi. I used to do that with windows mobile.
YES I know there are similar topics, but they are all abandoned and ignored.
I almost feel that it's forbidden to talk about that.
WHY I need that. I live in a country with NO unlimited data plans and very expensive mobile internet. That's it. I want to be able to sync, download and watch youtube while relaxing on the sofa at home without pennies dropping off my pockets for every tiny byte I download.
OK HERE's THE SOLUTION. Thanks to everyone who made the great tutorials available to us :
http://hydtech.wordpress.com/2009/09/14/how-to-connect-to-ad-hoc-networks-using-tmobile-g1-android/
The important part is to tweak the windows part - you need to tell the broadband/adsl internet connection to share itself to the Private wireless network (the network manging your Wireless adapter). If you are having trouble with the windows part (say you connect and have full bars on the phone but no access to web) google ICS (internet connection sharing) in windows and you should get it working.
*Important notice: AdHoc will drain your battery very fast (1hour tops)
Maybe one of the reasons they disabled it... If you cant cope with taht - get a router. I'm cheap and I'm using it like that

Possible solution
I downloaded aNETSHARE - a free aplication for wifi tethering posted on this forum as well. Inside the apk there is a tiwlan_ini file which might be executed when running the app so you can create adhoc connection on the phone. I have replaced the /etc/wifi/tiwlan.ini with this file and tonight I'm gonna try it on the laptop, but I guess it will only enable creation of adhoc networks on the phone.

Am I talking to myself?
I it's not the tiwlan.ini to be edited. There is a wpa_suplicant.conf file where the AP are stored. I will edit it tomorow and see if it works. Helloo unix gurus. Have some mercy on my mortal soul and help a little.

You do want to use a modified tiwlan.ini, but do not replace the system one.
Simply create a new one somewhere and use a command like this
Code:
insmod /system/lib/modules/wlan.ko
wlan_loader -f /system/etc/wifi/Fw1251r1c.bin -e /proc/calibration -i /data/local/tiwlan.ini
netcfg tiwlan0 dhcp
setprop net.dns1 208.67.222.222
The last two lines are to set up the proper IP address and dns server.

the backend of the wifi config gui uses wpa_supplicant. simply edit this and add whatever type of wireless connection you want. this is how we obtained wpa2 enterprise support. it was capable, the gui is just setup, for some reason, to ignore wpa2 enterprise/adhoc/whatever networks.
here's the original post from forever ago

... Wouldn't it be easier to turn your laptop into an Access Point?
Assuming you are under Windows, you can enable ICS (Internet Connection Sharing) and then use your G1 to connect to that.
Many people do the same to connect their XBOX360 for example to their laptop or computer to go online.

This is what he's trying to do. The thing is, by default a G1 does not see/connect to Ad-hoc connections, which is what the ICS setup will create.
All the information he needs to get his G1 to see/connect to Ad-hoc networks has been listed in this thread by now. Whether or not he will read any of it is another story.

Aaaahh... My bad. I thought the programs already had such a feature >_< Would be interested in this also incase I don't have any signal for whatever reason.

Thank you! I needed some help on that.
So if I create a internet connection in XP I have to specify a dns there and then enter the same dns in the last line, right?
I actually replaced the system tiwlan.ini (i kept the original) with the one from the aNETSHARE.apk but as expected it created an AP on the G1. I guess I will have to modify the WPA_SUPPLUCANT.CONF too. it should be something like
SSID="test adhoc"
MODE=1 (i think 1 stands for adhoc)
and some other lines i dont remember like the encryption mode and frequency. There are plenty of sample config files. Tonight I will try to do it.
But the question is - what do I modify in tiwlan.ini - is it only the line adhoc=0 to adhoc=1 enough or should I specify ip address and dns there too.
btw I did configure an adhoc network using the wifiHELPER app but all it did was add it to my wifi connections list without being able to see it. The only option was to "forget" the network.
Anyway. I think you helped enough, I will figure read the thread pointed by breaultm. Thanks. I actually couldn't find this very thread cos I searched with "adhoc" as a keyword. Thank you again. I really don't see why they omitted the support for this type of connection. My guess - either a security concern or they just want to make you pay for data plan.

Some reason you don't just use a wireless access point? They're DIRT CHEAP... for example: http://www.infonec.com/site/main.php?module=detail&id=352591 -- thats a wireless router (just disable dhcp server and don't use the wan port) PLUS a wireless nic for $34 CDN.

Well, I know. The cheapest routers are like 35 USD here in Bulgaria. Why not buy one? Call me cheap, but I'd better buy a bigger sd card first (I use a 4gb one now). I used to connect wirelessly with a pocketPC to the laptop and the connection was very stable. If I can't manage to connect the hard way then I will buy a router...

[Q] Hacking NC WiFi

So I've been roaming around the NC's system directories comparing the way the NC is layed out with Ubuntu, FreeBSD and OS X.
A couple observations:
1) I can't figure out where the NC stores the wifi access point SSIDs and keys. Does anyone know this?
2) I noticed that all of the configuration files seem to exist for tethering the NC and having it act as a WiFi card, though I can't for the life of me come up with a reason to do that. Has anyone played with this before I delve into it?
My hope I that this thread will become a source of NC wifi info.

1. /system/etc/wifi/wpa_supplicant.conf
2. no real reason to want to tether off of the NC that I can think of. I have tethered from my phone to the NC, but can't say I have any reason to try the other way at this point. In the future who knows what we might be able to do with this.
Looking through the file system you will see that B&N really did not try very hard to build their own specific file system, a ton of the vanilla android system is left behind. One day when we are able to have our own custom ROM's I would think that a ton of this extra stuff will be cut out to improve speed and battery life.

Thanks for the response.
I've had fun poking around the OS file system.
The /system/etc/wifi/wpa_supplicant.conf file is the template file, not the actual file where the wifi settings are stored.
The actual file where wifi settings are stored is at /data/misc/wifi/wpa_supplicant.conf
The template file shows that an example network configuration for a WEP WiFi Access Point would look like:
Code:
network={
ssid="actual_access_point_name_goes_here"
key_mgmt=NONE
auth_alg=OPEN SHARED
wep_key0=somehexidecimalkeythatis40charslong
priority=nn ##this is the priority rank in which you have want to connect to a wifi access point with more than one SSID is in range
The network configuration for a Ad Hoc WEP WiFi Access Point would look like:
Code:
network={
ssid="actual_access_point_name_goes_here"
key_mgmt=NONE
auth_alg=OPEN SHARED
wep_key0=somehexidecimalkeythatis40charslong
priority=nn ##this is the priority rank in which you have want to connect to a wifi access point with more than one SSID is in range
mode=1
The network configuration for a WPA WiFi Access Point would look like:
Code:
network={
ssid="actual_access_point_name_goes_here"
psk=somehexidecimalkeythatis40charslong
priority=nn ##this is the priority rank in which you have want to connect to a wifi access point with more than one SSID is in range
If I understand it correctly, you will need to remount the filesystem in read/write mode in order to pull/edit/push the file from the NC to your computer, edit the file, and then push it back and remount. I'm going to try this next and document the steps.
My whole purpose for this is that I have a long list of WEP, WPA, WPA2 wifi hotspots that I connect to on a regular basis. Typing in the 100+ hex keys for each hotspot is a royal pain without cut/paste. Instead it is just easier to pull down the file, edit it, and then push it back to the NC.

The reason you'd want to tether the NC to your laptop is if your laptop didn't have built in wifi (I know, I know, what kind of laptop doesn't have wifi?).
Some older laptops don't have wifi, and perhaps the wifi is broken so tethering could be a viable option.

WiFi Adhoc working with wpa_supplicant tweak !

Good news, the wpa_supplicant replacement tweak works on the Streak 7 too so the silly "neutering" by Google (to please the carriers apparently) can be circumvented. You can now connect to WiFi AdHoc networks, that's generally the type of network that a tethered smartphone creates, iPhone/iPad with MyWy, Barnacle on Android (http://szym.net/barnacle/), etc...
The Streak uses the v0.6.10 version.
Original trick is here : http://forum.xda-developers.com/showthread.php?t=754961
Since there was some confusion with the files I am uploading the one I used to make it easier.
The way I installed is :
- RootExplorer (requires rooted device)
- Go to /system/bin/
- Tap R/W at the top so it becomes R/O
- rename existing wpa_supplicant in /system/bin/ to wpa_supplicant.old
- paste new wpa_supplicant
- start and restart wifi
If you prefer to use adb, this command should do it :
adb push wpa_supplicant /system/bin/
You'd have to rename the existing one first though.
Hope it helps !

My s7 connects to my phones hot spot no problem?
Sent from my Dell Streak 7

Good for you, but that's probably because your phone creates a REAL wireless network like a wireless station, most tethering apps don't, like MyWi on the iPhone/iPad.

i have a streak 5 and with patches i got on other sites. They let me see the ad-hoc networks (*) but don't let me connect. All it does is go to obtaining ip address and the keeps looping at that.
Would this one act differently or will it not work for my little streak 5?

Probably wouldn't be any different, but that's strange, what AdHoc networks are you trying to connect to? Try to set their WiFi channel to 11 to see if it helps.

i tried to connect to my ar.drone and also a ad-hoc network i created on my pc. My wpa_supplicant is 0.5 on my streak at the moment. could that be the problem?
I can connect my ardrone to my pc. I can connect a laptop to my pc. But i can't get the streak past the "obtaining ip address". When i use static it connects right away but it connect nowhere.
With the new version of streakdroid it can with the ad-hoc fix included. When it didn't work i tried other ones and all with the same result. So i'm expanding my search to include similar systems.

Awesome!!!

THANK YOU SOOOOOOO MUCH!!! This worked perfectly on my Streak 7......I even ended up buying "Root Tools" for this but ended up really liking it!
I can finally hook up to the iphone 4 data plan I'm already paying for ;-)

works for me
Thanks for the help.

Error Message-DjSteve HoneyComb RC3
I get an error message when trying to turn on wifi on DJSteve's HoneyComb RC3 version.

Awesome
Thank you so much for this! Works great from my Hero to DS7

Finally working "Adhoc"!!
Use this method on my rooted, stock 2.2.2, T-Mobile S7, works great!! Thanks.
My S7 finally sees and can connect to the adhoc networks.
Tried the S7 on two phones using "adhoc" wifi tethering, both works!!
First one, my old but beloved Nokia 5800, using "JoikuSpot", S7 sees the adhoc network and connect to it with "wep enable" with no problem.
Second one, Sony Ericsson Xperia X10 mini pro, stock android 2.1, rooted, using "Barnacle". S7 can see the Adhoc network but have a hard time obtaining IP or may I say most of the time failed to connect. Then I went onto the Barnacle forum and they suggest a solution, which is first connect another device to the Barnacle first then connect your S7 after that. Somehow this method works. By the way this method also works on iPads. Barnacle aware of this problem, and is working on it. So what I do is first "jump start" the network connection by using either my laptop computer or my retired 1G iphone, both works great, after that adding addition connection to the Barnacle network is a piece of cake.
Once again, thanks "webvan" for the information and the mod. This finally make my S7 complete!!

Does this file need to be switched back for any reason or will it be ok if its left in place?
I mean will it change anything else by leaving it?

Someone please help me. I follow the steps by OP and when I try to access wifi I get a error and can't connect. Any ideas what I am doing wrong.

Worked great for me! I'm really mad at tmobile for not updating the s7 4g, I will enjoy halting my data plan.
Sent from my Dell Streak 7 using xda premium

i followed the instructions precisely, but when i turn on the wifi, it says "obtaining IP address...." then it turns itself off.... i returned to the old wpa_supplicant file (the original)
any idea about how to fix this?

I have a similar problem with my dell streak 7 honeycomb 3.2.
I can connect to Ad-hoc network created with my Android 2.1 phone. Every thing seems to work ok but after using internet browser for few secounds wifi is going down. Also if I connect to another, infrastructure network after that, problem repeats until reboot.
I used adb to push patched wpa_supplicant. To make it executable i used command:
adb shell chmod 777 system/bin/wpa_supplicant

I'm having the same problem. After applying the patched wpa_supplicant file using adb I can no longer stay connected to infrastructure networks. Ad-hoc networks stay connected fine. I've tried deleting the connections and re-adding them to no avail. A reboot or disabling/re-enabling the wireless works for about a minute and then it disconnects.
At this point I'm ready to go back to the stock wpa_supplicant file, if I could find a copy of it somewhere.
Any suggestions would be greatly appreciated.

SOLVED: Tether with android tablet

Hi,
I am having a problem using WM6.5 (EnergyRom Titanium) together with the Wifi Router in the Rom or WMWifiRouter for providing internet access to my MID816 Android Froyo Tablet.
First of all and for completeness, I had to make a little change to the WPA_supplicant.conf file in the tablet:
Code:
Ctrl_interface=DIR=/data/system/wpa_supplicant GROUP=wifi
eapol_version=2
update_config=1
[B]ap_scan=2[/B]
network={
ssid="droidhoc"
scan_ssid=1
key_mgmt=NONE
group=WEP104
auth_alg=OPEN SHARED
[B]priority=99[/B]
mode=1
}
The bold lines are the ones I needed to change.
After that I tried using the wifi Router and WMWifirouter with wep enabled (and the extra line in wpa_supplicant.conf), but that didn't seem to work, for some reason my tablet wouldn't connect.
Next I tried without wep and well it did connect (both WMWifiRouter and the tablet confirmed this)... but I couldn't access the internet for some reason.
I tried the same using the TP and my laptop and my laptop didn't have any problem connecting to the internet using wmwifirouter on the TP.
Next I tried installing XDANDROID on the TP and after some initial problems I got Gingerbread running on it.
I installed Barnacle Wifi Tether on the TP (the build in only gave errors), got it running without wep and connected to it with my tablet on the first try.
It even gave internet access to my tablet.
SUCCESS... well not completely.
XDANDROID, although a wonderfull development, seriously drains the battery of my TP (RAPH100)... so it is not the best alternative when traveling. It gives a temporary solution, but still.
So, after all this, I'm thinking, if xdandroid can connect and pass through the internet to my tablet, WM6.5 should be able to also.
Just, I have no idea what the big difference is here.
So, if anyone could help me figure out how to get wmwifirouter working with my tablet, that would be incredibly helpfull. Maybe someone does know what the big difference is between using wmwifirouter and barnacle wifi tether ...
TIA

Probably best to ask that question (since it is related to a specific project) HERE

I see, but the thing is, that I don't have a problem when using xdandroid...
The only thing that is giving met trouble is wmwifirouter :s

The reason it won't connect is the same reason why my wife's tablet or my PSP won't either. They connect in infrastructure mode only. The wifi router creates an adhoc connection. I hope this helps. I really, really wanted my PSP to be able to use the wifi router.

It's solved!
I stumbled across this post today: http://www.slatedroid.com/topic/385...-to-look-here/page__view__findpost__p__125320
the adhoc switching app doesn't work, but the line I have to use in the terminal does
This is the line I have to use in the terminal to be able to connect to the internet:
Code:
setprop net.dns1 192.168.3.1
Now, If only I could get that modeswitching program to work or even better use simple scripts to copy the correct wpa_supplicant.conf file and immediatly execute the above line...

And this (http://forum.xda-developers.com/showthread.php?t=486486) did the trick
I made 2 scripts:
adhoc
Code:
cat /data/misc/wifi/wpa_supplicant.conf.adhoc > /data/misc/wifi/wpa_supplicant.conf
setprop net.dns1 192.168.3.1
This one I have to use before turning on wifi and after the connection is made (could also have made 2 scripts but this works just as well
And returning to the normal connection mode
normal
Code:
cat /data/misc/wifi/wpa_supplicant.conf.normal > /data/misc/wifi/wpa_supplicant.conf
