SGS ad-hoc WiFi support (wpa_supplicant patch)

Hi!
Did anyone manage to connect to an ad hoc wifi network? Its my understanding that you have to root your phone and edit some files in order to do so. My phone is already rooted. Anyone willing to try it out and give the steps here?
Thanks!

Android 2.1 does not support this.

Yes! I know that! But i think you can edit some files after rooting in order to allow this?

Galaxy S wont find ad hoc AP, how to fix?
Hi, how to configure galaxy to connect to a ad hoc ap? It seems like wont find the ac hoc SSID at all?

Hello,
Ad Hoc Access Points support start with Froyo, if you really need it, give the latest XXJP2 a try

Any luck finding the answer?

Nope! No luck yet! And it seems no one is interested

have you tried modifying those files (wpa_supplicant.conf and others)?

Are you just trying to use your phone as a mobile APN? Because this is built into the galaxy S.

I am trying to use my wired LAN connection on my phone using the Laptop's ad-hoc wifi connection.

I'm reasonably confident that it simply isn't supported in Android 2.1 and that it's totally unrelated to config files (i.e. There's nothing your average user can do about it). I don't know if ad-hoc wireless made it into Froyo but there has definitely been an official feature request filed to Google for ad-hoc functionality.

i also find it very annoying that sgs doesn't support ad-hoc.

You can try to use this software http://www.connectify.me/

sadly it uses windows 7..

Can any dev please patch the SGS version of wpa_supplicant? Pretty please?
Another thread: http://forum.xda-developers.com/showthread.php?t=755254

really??
i couldn't find it even though i have jp3

The android OS filters out all Ad-hoc networks. There was a patched wpa_supplicant that seems to be working for some. I tried it and it does display the ad-hoc networks but fails when trying to obtain an IP... I am stay playing with it but I will update if I even manage a connection.

[Q] still no ad hoc in JPC??
is it true??
i tried a couple times and i'm still wondering about this ad-hoc problem

anyone?
i really need to confirm this

[Q] ad hoc in jpc??
is there still no ad hoc compability in the new FW JPC??
is there any trick to connect wi-fi from laptop to galaxy s.

[Q] Tethering Adam with a Windows Mobile device Adhoc, usb, or otherwise.

Hey All,
I have been messing with my Adam for a bit. I have been trying to figure a way to tether the device. I know Android 2.3 supports Adhoc networks, but not 2.2.
Although the Adam's kernal seems to be much higher revision than 2.2, the device itself only seems to have native 2.2 config options, with an Adam skin. With that said, I cannot get the Adam to tether/connect to an adhoc network, no matter what I try.
I have a Sprint Touch Pro. I can get it to detect as a 3G Usb modem in windows, and it automatically detects as such when hooked into a linux machine, but sadly does not do anything in Android/The Adam. The adam will pair with it over BT, but will not connect to it, and will not even see it in wifi-tether mode.
Any ideas? Is this something fixable with a settings change? Rooting? An app (on the phone or the adam?)
Any/all help or insight is appreciated.
Edit: I apologize, this was meant for the General Discussion. I don't see a way to move or delete this thread now, either. If the mods can move it, that'd be great. If not, I guess my questions still stand.

Assuming you want to tether to provide a more "mobile" internet connection:
Does your phone have some sort of WiFi tether app for it? If not you could attempt to run Android on your WinMo phone via Haret and then try installing a WiFi tether app and see if it works.
I would imagine to tether over USB Adam would need some type of drivers for mobile devices and that gets tricky. I would first try to tether Adam to a Windows or Linux computer with an Internet connection first, see if you can get that to work. Than go to your phone and try that. If it doesn't work from a computer it probably will not work from a phone.
If you want to tether for other purposes such as transferring files, SSH, SFTP, ADB, logcat, etc there are apps for those.

Correct, tethering for mobile internet.
I've actually tried the XDAndroid 2.2 and the 2.0.6 wifi tether app on my phone, but sadly it seems to create adhoc only, I've been unable to get it to create infrastructure, as well as it sometimes thinks it doesn't have root.
I'd have to get a male/male or female/female USB cable to try tethering to my PC, but i'll see if I can't figure that out.
Honestly, I'd be perfectly fine with Wifi tethering if the adam would detect Adhoc, as the XDA wifi tether android app can do that no problem.
Edit: On the windows mobile side, I've tried PDA net and internet connection sharing. Internet connection sharing supports Bluetooth DUN, but the adam doesn't seem to do anything with it, it'll pair but not connect to it. PDA net also seems to just do adhoc broadcast, which the adam cannot detect.

You answered the question before I could post it. (if you have wifi tethering capability on your phone)

So you tried 2.0.6 wifi tether app for WinMo? do you have a link for this app?

Er, no. I tried 2.0.6 wifi tether app for Android, running XDAndroid 2.2 for WM6. Link here to the app
http://code.google.com/p/android-wifi-tether/
I also tried wmwifirouter in windows mobile, link here http://www.wmwifirouter.com/

I had to replace my wpa_supplicant file to get ad-hoc networking working on my Dell Streak. Maybe its similar for Adam.

I'm trying to get in to modify the wpa_supplicant as mentioned, but I'm starting to think more and more the adam doesn't have superuser/root access like they've said, as all terminal apps I've tried have failed. Thanks for the heads up, though.
If anyone else finds any alternatives in the meantime, let me know.

You would replace the supplicant file on XDAndroid, not on Adam. The supplicant is for the system running wifi tether acting as the hotspot.

Ok, I feel stupid, but ptok's post makes it sounds like he modified the supplicant on his streak so it would see ad-hoc networks.
Wouldn't I want to modify the Adam so it can see ad-hoc, since my phone can already push out ad-hoc even in WinMo?

Good luck with that. You're talking about reverse engineering drivers, recompiling kernels, and a lot of time spent for little gain and possibly no gain. It is almost always easier to attempt to get the wifi spewing device to act as an AP than it is to get something else to comprehend ad hoc networks. Besides, security is stronger with the former than the latter.
What about the XDA WiFi Tether from here. Is it any newer, is there an option for WPA? If not thats about all the help I can provide. You are probably going to have to go to XDAndroid forums and ask how to turn the phone into an AP or ask about WPA supplicant info.
Just remembered that some folks on XDA were trying to do the same thing with the Hero I think. They started some stuff and never finished, but did get WiFi Tether to support WPA which is a step in the right direction. You could hunt around the Hero CDMA dev forum and see if anything exists.
Sorry I couldn't help more.

I get a "You are not authorised to read this forum" when I try to follow this link. However, I do see that the Notion Ink Hacks update includes Adhoc. Cool.

Tried that on my friend's Adam. It worked.

I can confirm that the NIH updates have enabled ad-hoc tethering, and it works great.

Ad Hoc
What ROM did you use that Ad-Hoc worked on? I am running EdenX and I can connect to an ad-hoc network, but not actually use the internet access through the connection.
[Edit]
I was using WMWifiRouter, which resulted in the scenario identified above. I downloaded the HTC Wifi app that I found in one of the other XDA forums, installed it on my phone and created a hotspot with it and it worked fully. Apparently there is something different in the HTC implementation as compared to the WMWifiRouter app implementation that lets one work fully and the other only to allow a connection, but not access the internet.

I simply set my Nexus One as a WiFi Hotspot ... configure it with a SSID and WPA2 PSK security and a Password ... then turn on the WiFi on the Adam and enter the Passphrase. Away it goes. That is why I ordered a WiFi only model.

[Q] WiFi tethering

I have just got my hands on an ASUS transformer tablet . Now I thought ok it's wifi only thats fine I can tether it to my little tattoo and use 3g that way.
Problem is I didn't realise that Android doesn't see adhoc networks to connect to them. So I want my wireless tether to work in infrastrusture mode instead of adhoc.
I've been searching and seen this done for other phones but can't seem find a way to do it on the tattoo/click.
Has anyone found a way to do this?

Well there is a wifi tether app on market wich does the job...with that app your tattoo works like AP for 3G network. Also i think that your tattoo must be rooted.

I'm already using it. Version 2.0.7. but it broadcasts in adhoc mode so the tablet won't even see it.

Well i dont know what to say, my laptop work just fine with wifi tether app on my tattoo.

It will do. Mine to because laptops can see adhoc networks.
Or is there a way to enable android native tether instead of using an app. I've read somewhere that works in infrastructure mode.

I have a similar problem too! It seems that nothing but computers can see ad-hoc networks. So, my Kindle, my Xoom, and other smartphones can't access the network through tethering. Is there a way to make wifi work in infrastructure mode?
Nobody else have had such a problem?

Have you tried this setting?
Wireless Tether:
- Install Wireles Tether from market
- Run app
- Press on init "tethering"
- go to "menu" -> "settings"
- Enable "Wifi-Encryption" For safety...
- Change "Passphrase" (13 chars)
- Change SSID if you want

Yes, I tried: that creates a wep-protected ad-hoc network...

[Q] No DUN no ADHOC rant.....Honeycomb 3.1?

So all of our phones with Wifi hotspot features create an ADHOC connection which Honeycomb does not support. Same goes with Bluetooth, no DUN. Google what the hell? Ya ya,carriers this and carriers that but what about people paying for hotspot features on the phone. I have customers that I need to setup to pair with the TF but it seems nothing will work without rooting and that can be phone specific. So the TF is great as long as you are close to a WIFI connection is supports?
If I'm missing something someone please fill me in.

I am using the hotspot feature on my Evo, and I've been tethering to it at work since the day I got my Transformer. I'm not doing anything special, just turning on the hotspot and letting the TF connect. Now, my Evo is rooted with a ROM that "unlocks" the hotspot functionality so I'm not paying extra, and I'm not using the Wireless Tether app, but it's the same concept.

The hotspot feature on your ROM is supporting a true wifi connection and not peer to peer adhoc. I can't always root customers phones.
~DC

I may be misunderstanding how it works, but this isn't a wireless tether baked into the ROM, it's the built-in Sprint hotspot feature that I'm using, just unlocked so I don't have to pay extra. If someone was paying for the hotspot feature on Sprint, they wouldn't need root, but maybe this is only the case with Sprint's implementation.

i was able to do both wifi and bluetooth tethering. took me a while to figure out, (since i've never done it before, less due to the difficulty of doing it)
assuming the phone supports Bluetooth tethering, it should always work.

I have a DroidX and I can tether using the built in stock Hotspot feature or with Bluetooth. However, I can't tether using an ad hoc connection because I get an error stating that the device doesn't support ad hoc connections...
So, it is definitely device specific and it will be something the carriers remove as many report being able to do so with root (my device is rooted and I can't connect via ad hoc - although, I haven't d/l or tried out the pdaNet app).
I will also add that the bluetooth tethering has worked MUCH better than the wifi - easier/faster to connect, runs pretty fast, and my phone doesn't overheat as much....

Works fine with my evo. The Evo has proper infrastructure wifi hotspot.
Maybe the users need to update their phones?

I went into a store to try a tf and there was no internet so I turned on my WiFi hotspot on my sgsII and it worked perfectly fine, not sure if that's the same as you're asking but that works.

a lot of clarification
Hi all,
I need your help, understanding ... well everything about wifi/TF/WM6.5/adhoc and whatever the other connection is?
I don't think of myself as a noob, but to be honest I'm lost with the wifi on the TF. So here it goes: I have TF and HD2. Under WM6.5 I can't get the TF to see the shared internet through the "wifi router" application on the phone. But then I run a custom Desire HD ROM and this one (can't remember the application) shares and gives access to the TF?!?!
First off, which is which? Which is adhoc and which is infrastructure? And what is the difference (sorry i did look on the internet, but that got me confused even more because I could not see any difference). Are you saying that a standard (not rooted Android) will have the same problem? I was thinking of switching to an android phone so that I can get the easy sharing option, but if I have to root a brand new phone????
Any help will be appreciated,
rio

Easy way to tether off a rooted phone.
Install one of the older versions of wireless tether that supports bluetooth.
Turn on the bluetooth DUN on wireless tether.
Hit ok when it asks to turn on Bluetooth and make discoverable.
On the transformer go to settings-wireless-bluetooth
Scan for your device and pair.
Once paired you should see a little wrench next to your device, click on it
Under Profiles, it should show tethering with a checkbox. Click this and in a few seconds Wireless tether should buzz its connected and off you go.
I've been able to tether my transformer like this since out of the box.
Edit - BTW I've tried this with PDAnet and other non rooted tehtering programs, and I couldn't get it to work with those options. Just FYI

the difference between ad-hoc and infrastructure is the way devices communicate.
infrastructure is kinda like the way we send messages via the post office. we send it to a central place, then it figures out how to deliver the message. this is how true routers operate
ad-hoc is peer-to-peer. imagine passing notes back in elementary school.
( Do you like me [yes] [no] )
some phones comes with a tethering app without having to root, but this typically requires you to pay extra fee to your carrier ($30 for sprint)
if you don't want to pay that, then you have to root your phone to either get a rom that already supports infrastructure mode, or download an app that does. [ ie Wifi Tether ]

You are right. I put Honeycomb 3.1 in the title but forgot to mention in the OP if anyone heard that 3.1 would have support for DUN or Ad Hoc.
Sorry for any confusion I might have caused

[Q] Will Adhoc WIFI be possible with software patching?

So I'm sure a lot of you had the plan that you just enable wireless tethering on your android phone and connect your kindle fire that way... Well Amazon in their infinite wisdom has disabled that ability. That is pretty much my number 1 need at the moment. I travel a lot and this should have been the first thing amazon added support for since they don't offer a 3G version.
Hopefully with some roms this will be working

As a temporary work-around, certain wifi-tether apps can be setup for infrastructure (rather than ad-hoc) mode. May be worth looking into.

Amazon didn't do it, Android in general doesn't do adhoc. OeMs and users have to patch in Support for it.

No, its the kindle. Try setting up a adhoc wifi from your PC or laptop - the Fire won't see it but phones with e.g. cyanogenmod will. Still trying to find a workaround as I need adhoc wireless from PC/laptop...

I got my kindle to connect to my Captivate running wifi tether 3.1, but it wont actually transmit any data. I use static IP's with my home network on the kindle but that shouldnt impact the infrastructure mode with wifi tether would it?
