How do I make it see ad hoc wi-fi networks? - Galaxy S 4 Q&A, Help & Troubleshooting

The only available Wi-Fi network at my work is an ad-hoc one and my S4 doesn't see it. I really need to use this Wi-fi, any solutions for this?

I'd like this as well.
I've tried numerous approaches with replacing the wpa_supplicant file and such, but nothing really works.

After trying pretty much everything I could come up with and everything other people have come up with, I'm beginning to think it's not possible to get ad-hoc networking working on this device.

Android should be able to support that, maybe the ROM is not able to support.

I guess I could try to install Cyanogenmod and see if replacing the wpa_supplicant file there works.

Connection sharing pc to android (no tethering

hello,
i would like to know if it is possibile to share my pc connection with my htc legend:
the problem is that in my room my laptop get the wifi but not the phone because it has a really really bad antenna, and i dont want to use 3g data, is it possibile to share my connection from pc to phone? it should act like a wifi repeater or something no idea thank you
A while ago I was looking for the same thing.
Although technically an easy task, it's not yet possible with Stock Android. There is a Google Code forum page confirming that Android as of yet can't see and connect to Ad-Hoc networks. There are some wifi-tools in the market that can at least show them, but none can't make your device connect yet.
Some ROMs seem to have added this option, if you plan to root and flash. I just added a cheapo router, problem solved. ;-)

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?

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
Sent from my GT-I9000 using XDA App
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..

[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

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] Connecting to Adhoc Networks

Hello everyone,
As we all know, Honeycomb out of the box does not support/enable connecting to Adhoc networks, which many WiFi tether programs use.
There is a fix out there for the Nook color, and previous Android versions, but they do not appear to work for the Tranformer (tried both the .zip and manually but not the manual method).
I am unknowledgeable with the Android OS, and would really like to figure out a way to make my Transformer connect to an Adhoc network.
Any links or comments is appreciated!
Thank you.
Me to,
I just tried to Wifi tether to my Droid and it didn't work. I have no trouble doing the same with my Viewsonic Gtab. I know i'm using Gingerbread on the Gtab and not Honeycomb, but a solution to this problem would be great.

This is true, and I was able to get it to tether by upgrading and using infrastructure mode, but I believe there are many things such as some corporate networks that use Adhoc.

I seriously doubt that many corporate networks are using adhoc Wifi networks!
Out of the box, Android doesn't support adhoc networks, but it can usually be enabled by editing the wpa_supplicant.conf file on rooted devices.

ADHOC WiFi mode for N7

anyone have adhoc wifi mode working????
I'm also wondering...
But in the mean time, you can use FoxFi on your phone and Bluetooth tether it to your Nexus 7 via PdaNet Tablet.
ya....my media server runs in ad hoc mode......it will be a big bummer if I can't get it to work
anyone??
I also need this as well. My research suggests the wpa_supplicant file requires modification to enable ad hoc. I don't have the skills to accomplish this. Maybe a dev can help out.

i need this bad too but i cant try that wpa supplicant thingy until this weekend when i have more time...
i found a bunch of the "thingys" and none work
someone please help thanks
again?
Ad hoc is a spec that is archaic, and really only supported through 802.11g. For 802.11n chips like the one that N7 is using, I don't recommend using ad hoc before there is no guarantee of interoperability. There is a new WiFi feature called wifi direct that is supported in jellybean that can do what Yu need but it depends if you have this supported on the other side as well.
Thank you. I do understand the downside of ad hoc but due to circumstances beyond my control, I am only able to access the internet via a
ad hoc WiFi connection when I am mobile.
my kindle fire on CM9 had the same issue
I way playing with a Nexus 7 today in store.
checked to see if it would tether to my iphone 4s
newp, same issue, no adhoc
would have bought it there and then otherwise.
Same issue here. Just got a Nexus 7 and didn't know Android still doesn't support connecting to ad-hoc networks. Anyone know if there are any devs actively working on this?
I may have a solution. On prime, we had a similar situation where they nerfed the ad hoc tethering capability For a few firmware versions. How it was solved was by replacing a certain wifi supplicant file. There's a good chance it might work on this device also. Its pretty simple to apply. Here is the link to the thread and a link is in there also to the wifi supplicant file to Insert in your device. Its worth a shot. I believe you must be rooted though to make it work as it requires changing permissions of the newer file.
http://forum.xda-developers.com/showthread.php?t=1438297
Also a good chance one of our custom roms for nexus 7 will add in ad hoc tethering ability. Just ask if it supports it or politely ask for feature to be added.
i too would love and appreciate if anyone could get ad-hoc working. my old phone can only make an ad-hoc network for tethering, and i'd like to be able to tether it if i need to
Also would like ad-hoc so I can connect to my quadcopter.
Are we still in the dark on this one? No one has a solution besides Bluetooth DUN?
Anyone know of a rom that supports ad-hoc?
FOUND A WINNER!!!
This free app works for wifi tethering in "WiFi HotSpot" mode with password protection! All on stock 4.2.1
I hope that y'all find it as useful as I do. I see a paid version by the same Dev, but I don't really get what the difference is. This one seems to be a full version AFAICT.

the app you are pointing to is a totally different thing, it is for sharing "your" android's internet connection with others devices, so please be very carefull when recomend something becasue we could thing you are putting spam here.

Several of the posts here address people's desire to tether their phone to their N7. And while the app I posted a link to doesn't help us connect to ad hoc networks, it may very well help some in this thread. I don't see how that could be misconstrued as spam.
Hello
I've been doing some research since I got my n7 wifi, I need to connect it with my nokia 808 with joikuspot, so far I got connected and some apps are working but others dont, it requires to root your device, install a custom kernel and copy a patched wpa_supplicant, the main problem seems to be that the android kernel doesnt support at all ad hoc (IBSS) networks, looking for an explanation at code.google.com even the developers complain that the android SDK lacks support to develop apps with ad hoc networks, AFAIK we need some android guru who can compile the ad hoc module into the kernel and patch the wpa_supplicant so it wont filter out ad hoc networks, you can check my findings here.
