[Q] Cannot see wifi from another cell hotspot - Galaxy S III Q&A, Help & Troubleshooting

I have my HTC Desire, on which i have a large data bundle which i can use. I created a wifi hotspot from this phone using Barnacle and Wifi Tethering from OpenGarden.
I create the hotspot (tried both apps), and i can see it from my pc, but i cant see it from my SGS3?
Any help?

Give this a bump to see if anybody can help.
Thanks

Final bump, hope somebody knows why the SGS3 cannot pick up wifi hotspots from other phones.

If the other phone makes Ad-Hoc access point the S3 can't access it and so far it's impossible to make S3 use Ad-Hoc.

wow scary
But isn't possible to modify the wpa_supplicant like it has been done for other versions of android ?
I read that the trick was to make the wpa_supplicant "think" the ad-hoc was infrastructure.

Every method so far kills the Wifi connection so you'll have to wait.

Thanks for the feedback. Did not know the SGS3 would not be able to connect to ad hoc wifi hotspots..
Any idea why they went this route?

Because Android by default does not support mesh networks (also called adhoc).
The reason it that wpa_supplicant's adhoc support is badly broken while adhoc networks consist of a complex peer-to-peer protocow withoue central infrastructure: insecurity, slowness and stabiliy issues are the consequences.
Only a few phones have adhoc support in a Rom with, afaik, all these roms being aftermarket
Are you sure your HTC phone is not capable of AP-mode wifi?

My HTC Desire is rooted, so i did some googling and found out that wifi tether can be used and will simulate an infrastructure hotspot.
Now my SGS3 can see the hotspot, but its not connecting properly. Keeps getting stuck on the message "Obtaining IP address" so i am not sure if thats a problem on the HTC or SGS3 side.
Will do some fiddling today.

Application similar to Verizon Hot Spot

Is it possible to create an application similar to Verizon Hot Spot, then Archos can connected and work fine?
Its not an app issue that you can solve on your phone, its a hardware issue. Verizon hotspot app works in "Infrastructure mode" (ie Routers, real accesspoints) because the phone wifi hardware allows it. Most phones and laptops with wifi don't have that, and will only work in Peer to peer mode known as Ad-Hoc mode. Unfortunately the wifi scanner on Android was coded to ignore Ad-Hoc signals.
If you can't use Wireless Tether for Root Users, try tethering over Bluetooth by changing its options.
I have tried Barnacle and Rooter for LG Ally(SUperOneClick) from this forum. But as I uderstood right Adroid Archos 70 would not see it becuase didn't have capability to see Ad-hoc.
So I was thinking here a lot a very talant programmers, so if Verizon creat Hot Spot, that works as wifi rooter, so someone be able create similar to it for rooted users.
Thanks
Not true. If you have the hotspot app it will work. Depending on the phone you have you can download ROMs that have this app built in/hacked in that will work to tether.

Wireless Tether has been updated to work in infrastructure mode. I tether my Archos with my Droid X. Made this thing so much better for me.

Wireless Tether for root doesn't provide "infrastructure mode" on the Fascinate. Also, Bluetooth tether does not work on the Fascinate. (keep getting "unknown state")...
Obviously the phone is capable of infrastructure, because of the "hot spot" app, which does work with the Archos....
Gotta get the Wireless Tether for Root guys to fix it for the Fascinate.....
Wireless Tether supported hardware...

[INFO] Wi-Fi Tether Touchpad to Rooted Andoid Device (Hotspot)

Hey everyone, just wanted to let you rooted android users out there know that you can tether to your touchpad pretty easily.
Go download the newest version of wifi tether 3.1beta5
http://code.google.com/p/android-wifi-tether/downloads/list
Install it
Run it
Menu-Settings
Change Device-Profile
Select Samsung Fascinate
Change Setup-Method
Select Softap for Samsung (Master)
Back to main screen
And now you are good to go. I have used this on my fascinate running the community rom, also read that someone had it running on their charge as well.
Have fun tethering.
Post back if this does or doesn't work for you, what device, and what rom/kernal you are running.

I cannot seem to connect Touchpad to any adhoc WiFi network. Really would like a fix for this one. iPads and iPhones connect to adhoc networks just fine.
I would manually enter the ssid, broadcast id, network id and ip address and forget dealing with dhcp if it's not working
maybe reboot? Mine works flawlessly on my android and touchpad
From what Im gathering, my HTC hero uses ad-hoc and the touchpad doesnt pick that up. Shame, but I have a feeling Im SOL.
Try turning off all the security settings etc...

Some android phones can only broadcast wifi via adhoc mode which is incompatible with the touchpad. Its not a matter of what program you choose, if your phone can only do ad-hoc wifi then it wont work. Try using bluetooth (Wireless Tether 2.0.7)

Any idea what version to use for the photon? I tried this one and I just get errors. Thanks
Wifi tethering the touchpad works great using my HTC incredible (running CM7). Must be the ad-hoc issue others have mentioned.
i had issues getting my tp to connect to the wireless hotspot from my desire s.
as soon as i changed the security type from wpa2 to wpa it started working.

The reason for that might be that they are two different standards of encryption, lollol, neither is backward/forward compatible with the other

yes i know that. i'm not a dickhead.
the TP is supposed to support WPA2, however it had issues with WPA2 on my desire s.
This does not work for me Either-it keeps saying 'Tethering but with Errors-see Log' and the log cannot load the Sofap part...
I have a feeling some phones can only broudcast WiFi in Ad-Hoc-Like my HTC HERO It may be time to say goodbye to it after all...I was actually hoping the TouchPad would mean i dont need a new phone as most of my stuff (good Flash Web Browser/Email/Games/Whatsapp/Facebook) would be sorted between the two devices....Oh well....
I believe the easiest way to tether from your rooted Android to the Touchpad is if you're running CM7, to use the built in wi-fi tether as it works flawlessly!
i dont see this option for fascinate
Select Softap for Samsung (Master)
i only see WEXT (ad-hoc)

This question should be posted in the general section, not development....
BUT, android can't natively connect to ad-hoc networks without a modified wpa_supplicant. You should search in the forum for your Samsung tablet for a compatible wpa_supplicant file, and you must be rooted to install it.

Is your device temp rooted or you have wifi tethering plan with Verizon?
You can download and run CleanTool to temp root your device and install any wifi tethering app on the market.

Wifi AP

Does anyone know any apps that creates a Wifi AP? I am not talking about an Adhoc network that all apps I have used create, I want it to work like native tethering.
I am asking because I am using polish blood preRC, and I really want to use it full time, the only thing is native tethers do not work and all apps create an Adhoc network.
Normally this isn't a problem, however I wish to use my PS3 over my phone's 3G connection, this is where the problem comes in, the PS3 does not see Adhoc networks so most, if not all tether apps will not work.
I have tried to use connectify while I have a usb tether connected however the PS3 cannot connect to the internet, I also would prefer to avoid using my laptop as an AP.
So anyone know a decent Wifi tether app that will create an AP like native tethering, not an Adhoc network
Are you sure that PS3 cannot connect to Ad hoc networks?
Here is an article about it http://www.ehow.com/how_6808376_can-connect-ad-hoc-network_.html
and it says PS3 can connect to Ad hoc networks.
Check if you configured everything properly.
Also Wireless tether app supports AP mode but only on certain handsets (HTC Evo 3D for example). It looks like it doesn't support our device.
Mine has never seen an adhoc network from my phone, guess I'll check it tonight when I can get on it.

Check wifi channels, anything between 1-11 channel will work.

Don't use this ICS. It's still in very early stage of developement. It's only for money.. If you really need a ICS on your Swift, then try AOKP 4.0.3. by DevSwift. Probably an update will come very soon. I was using it on my swift for 1-2 weeks, and I was happy with it. Now I changed the whole phone.

Back on topic, ps3 definitely will not see an adhoc network, just tried and when I scanned it didn't pick it up, when I entered my ssid manually it said it could not find it.

Sorry for the mislead, PS3 doesn't work with ad hoc networks.
But here is a possible solution:
1)Download latest WiFi tether beta http://code.google.com/p/android-wifi-tether/downloads/detail?name=wifi_tether_v3_1-beta11.apk
2)Open it and then go to Settings
3)Change Device-Profile to Google NexusOne
4)Change Setup-Method to Netd (master)
5)Start tethering and that's it
Note: I haven't tested this on Mike's CM9 but it did work on CM7, so try it, and tell us if it works.
Just to warn you there is probability to get kernel panics with this settings.
EDIT: I have tested this on Mike's CM9 and can't get it to work. Simply wait till Mike fixes WiFi tethering, or flash CM7 or some other ROM.
You can try a couple of options...
1. Hosted Network Starter
Free: Simple hostpot on your pc with non configurable DHCP
www.nirsoft.net/utils/wifi_hotspot_starter.html
2. WiFi Tether Router
Paid: Android app for rooted phones with full featured DHCP, VPN, etc

Windows 7 - ad hoc connection

Hi,
I created ad hoc connection on my Windows 7. But my galaxy s3 can't detect it.
I tried both using Wi-Fi Direct feature, and regular WiFi. But S3 doesn't see that ad-hoc connection.
Why ? Anyone was able to do that ?
Regards,
Pawel
Most Android phones can't see Ad-hoc connections due to limitations (too many issues) in the underlying Linux library and service.
CM9 can see and use it just fine, and there is a fix for most other phones.
Roughly 9% of all computers are capable of running the network card in Host-mode and not only adhoc, so try using Connectify which builds a true Wifi accesspoint.
If it's only to share data between the phone and computer, you can afaik also use the Wifi AP in the phone to connect both.
I've been trying every fix I can find for S3 but everything breaks the Wifi connection, so does anyone know any way to get it working? Because obviously you can setup most routers not to use Ad Hoc but I tried to tether to some Symbian phones but they can only create an Ad Hoc connection.

Most routers actually WONT use ad-hoc unless specially configured to do so. And many don't even know the concept of mesh networks =)

Test if the following (still) works:
http://acetips.wordpress.com/2011/10/07/reverse-wifi-tethering/
It uses your phone's full-fledged Wifi AP to reverse-tether to another phone.
However it requires a somewhat complicated setup on your Symbian phone which I'm not sure it can handle.
Alternatively you need an extended wpa_supplicant binary to handle ad-hoc.
I'm not sure if any good ones exist, except for CM9. (Which might/will be incompatible with Stock ROM's)
You can use connectify for windows to create connection in the form of Access point
As far as I remember the Nokia N900 is the only one capable of that because it runs on Linux but no version of Symbian can do this because even custom Roms on there consists of basic file swapping and no real system access, and I did used to use Ad-Hoc enabler but that does just kill the Wifi connection now, and they removed that from the market now because they say they updating it hopefully for ICS.
Connectify has one drawback. You can't share 3g/4g connections on the PC, unless you have a premium version.
VirtualRouter doesn't work on my system for unknown reasons. It says service not started, even when it actually is.
I tried VirtualWifiRouter from wwwDOTvirtualwifirouterDOTcom. Seriously good..
