Wifi tether not showing up on Android 4.0+ phones - Android Q&A, Help & Troubleshooting

Hi there,
I have an unlocked T-Mobile mytouch 3G that I'm trying to share my wifi connection from. My computer can see the WiFi tether with no issues.
My wife's Droid Pro running a version of Android 2.3 can see the connection(as an Ad Hoc connection).
However my Galaxy SIII and my friends S2 both on Android 4.0+ cannot see the wifi signal.
I'm currently using Wifi Tether Root but have tried a few different applications. Any ideas of what I can do?

[Q] Help: ZT-180 and Adhoc

Hey All,
First post here in the Galaxy tab forum but I frequent the XDA phone forums. I have a question (and I have done plenty of searching online and in the forums) but can not seem to get this to work.
My Galaxy Tab 10.1 WIFI only is rooted and has the newest TASK650 ROM installed. I am using the Motorola Photon 4G (rooted as well) with Barnacle WIFI tether. The Photon creates an adhoc network.
I have installed ZT-180 adhoc switcher on my Galaxy Tab and can not seem to get it to connect to my phone for tethering. I have made sure the SSID on both the ZT-180 app on the tab and the tethering app (Barnacle) match.
In the ZT-180 app on my Galaxy Tab 10.1 WIFI only, I switch from infrastructure mode to adhoc and it will not connect nor does it seem to do anything.
When I switch back to infrastructure mode it will connect to my home internet but switching to adhoc mode does nothing. Barnacle WIFI tethering on my phone is running and I can confirm I can connect to a computer for access. I have disabled WEP security just to be sure.
I know this topic has been discussed before but I could not seem to find the answers so I came here.
I hope you all can help a brother out.
Thanks again!
-Matt
Anyone?
Edit* i was able to connect my phone and tab via bluetooth and turn on Barnacle tether and it works. Thanks

Open Garden WiFi not compatible with ICS?

Hey all, I've been using Open Garden Wifi tethering on my unlimited data Verizon 4G Samsung Droid Charge to provide internet for my prime.
It was working perfect, without a hitch, but now that Ice Cream Sandwich has been installed my network wont even show up on the list. Interestingly, the network shows up on WiFi Analyzer on the prime. Anyone else have this problem?
Its been working for me but im on a 3g incredible
what frequency channel, transmit power, and LAN network settings are you using?
I have the same issue actually. My prime cannot connect to my CM7 hotspot app that's integrated into the ROM, nor open garden, nor Wireless tether (open source)
What gives?
Hey guys,
I can connect perfectly fine to my old HTC Desire (CM9 WiFi Hotspot) or HOX (HTC Sense WiFi Hotspot) but Open Garden doesn't work.. too sad. (All Devices with Android 4.0.3 or above [the Desire])

[Q] Verizon 4g tethering to Wifi only GT 10.1

I have a Thunderbolt (rooted & rom) Verizon 4g (w LTE) smartphone and trying to tether to my wifi only GT 10.1 (rooted only - SockMonkey) tablet.
Things I've tried and used:
Open Garden, Barnacle, Google Tethering, Hotspot on Thunderbolt
I have tried WPA_supplicant fix, no help there.
I get connected with Open Garden with 4 bars, but not on internet.
I've read it's the Ad Hoc difference Verizon not working with Android wifi.
I would appreciate some help now before giving up.

[Q] Getting Internet from my DsL Laptop to my Android Devices

Hey guys,
I am currently really desperately looking for a way to get Internet from my DSL-enabled Notebook to my Galaxy S2 and my Asus TF700T Tablet. I am in Finnland on a hotel so I don't have 3g here.
So the facts:
My Laptop has a Wifi Bigfoot Wirless n 1103 network card without Bluetooth.
First I tried to do is setting up a Virtual Wireless Hotspot which kind of worked, but only for a few moments. Got a connection on both devices but then the Hotspot somehow disappeared. Don't know why. Maybe it is due to the Network Card, which is built for good gaming performance over Wifi.
Anyone an idea whats wrong with my Virtual Wifi Hotspot?
Next thing I tried is to set up an Ad Hoc- Wifinetwork over the PC which kind of worked, but both Android devices can't see ad hoc networks and there seemed to be no working wpa_supplicant for jellybean. Both Android devices are on PAranoidAndroid 2.99 by the way and the Laptop is on Win 7.
Does anyone know a way to enable this to see Ad Hoc Wifi networks?
So next thing I tried is Tethering over USB with Android Reverse Tethering which worked for the Tablet but not for the Galaxy S2 for a reason I dont know.
So does anyone know, why it does not work on the S2?
Next I tried setting up a Wifi Hotspot on the Tablet with the app Wifi Tether which kind of worked, but unfortunately this is an ad hoc network which again my Galaxy S2 can't see.
Does anyone know an app that creates an infrasturctured Wifi Hotspot instead of ad hoc?
Then I tried setting up Bluetooth Tethering from Tablet to GS2 which I didn't got to work (Connection established but don't know how to get the Internet working then.
Anyone got an idea about this?
Anything else I could try?
I really didn't believe that this is so hard to do

Wifi tethering connected devices limit

Hi,
Two months ago I installed Cyanogen ROM (Kitkat 4.4.4) on my Samsung Galaxy Ace mobile. Now I am trying to enable wifi tethering for my 3G sim using my mobile.
When I enable wifi tethering I can't get internet on more than one connected device (if there is only one device connected it can access the internet, but when another device connects to the tethering wifi network only the lastest one can access the internet while the first one can't even ping the mobile ip !!)
I tried "Foxfi" and "wifi tether for root users" application, with no hope.
Can I connect more than one device to my Samsung Galaxy Ace wifi tethering network using my current Kitkat ROM? if I reinstall the original stock ROM can that fix the problem? is this a hardware limit or a software limit?
As far as Im aware only one phone can connect to wifi hotspot on ace (cm 10.2,cm11).If second connects first one drops (in my case).For stock I honestly do not know as I've never used it while I was on it.
If you have time and are willing to flash stock,please report result as Im also very curious whether its a hardware of software limitation!
CM ROMs have wifi issues.
