Wireless Tether not working on rooted SGSIIE4GT running on Zedomax v3.

Took the leap 2 days ago and rooted my Samsung Galaxy S II Epic 4G Touch using Odin and the Zedomax v3 kernel. Root went fine and after a short minute I was rooted and installing Titanium Backup Pro, ROM Manager Pro and Wireless Tether For Root Users.
Having (free) wifi tethering is a must for me as I have a Samsung Galaxy Tab 10.1 (wifi version 32GB Grey) and need network access when out abroad and in the car. After installing the app from the market, I promptly opened it up and started tethering with all of the default settings (no encryption, ssid = AndroidTether, access control is disabled). The app shows that tethering is activated with no errors and broadcasting the signal. Now I switch to my SGT10.1 and open up network settings but there is no AndroidTether network seen. I refreshed multiple times and still nothing. So I grabbed a few other wifi devices (laptop, blackberry) and still, no AndroidTether network is seen.
I have checked the in-app Wireless Tether Log and there are no errors or failures. I have tried rebooting the SGSIIE4GT and still have same issues. I flashed back to stock kernel (rooted) and still have the same issues. Then removed root, rooted agin with Odin to Zedomax v3 and still same issues. Went to the distribution page for Wireless Tether and downloaded other beta and prior stable versions of the app and still same issues.
Soooo.... then I thought, maybe the hardware that broadcasts the wifi signal is busted. So I flash back to stock, unroot and go to sprint today. They activated my Sprint Hotspot service and BOOM! Pull out my SGT10.1 and the network is right there. Connect to it and it works just fine.
What is frustrating is my brother bought an SGSIIE4GT as well, we have the same hardware versions and running the same ROM and kernel and he can tether with no problems.
Not sure what could be causing the problems but hope I can get it sorted soon. Would very much appreciate any insight from anyone on new things to try. Anyone even having the same problems?

My guess it is because the Galaxy Tab doesn't support ad-hoc wifi tethering, which is what the wifi tethering app you're using broadcasts in. Had the same problem when I was trying to use it with my Touchpad. You will need a tethering app that supports infrastructure mode to be able to tether to your tablet.
Fortunately, Necrosan has been able to hack the built in Sprint Hotspot app (that uses infrastructure mode) to get free 3g tethering. That thread is here [HACK] [EG30] Hotspot Hack (3G Only for now)
You will need to be rooted and be using a deodexed EG30 rom, but there a quite a few of those around. I'm using [ACS][Odin]Stock EG30 Deodexed with Root 3.0/Busybox 1.18.4 and it is working great for me. Haven't even had LOS yet.
After you get all this done you should be able to use the Sprint Hotspot app and tether to your Galaxy Tab. Mine has been working great with my Touchpad so far. Hope this helps!

My brother (as stated above with the same hardware and software) tethers just fine to his SGT10.1 and his iMac....

To make sure its really broadcasting you should use a laptop or another computer with wifi to look for the SSID. If you see your device then the problem is probably the one stated above. If not, then there is definitely something else wrong
EDIT: just read that you already tried this. Sorry man, don't know what to tell you :/ If the Sprint Hotspot worked then I would just used the hacked version I mentioned previously to avoid paying monthly for it

Thanks for the responses, will give this a go sometime this week. Thanks for your help mate.

I've found that "Wireless Tether for Root Users" does not work for me on the ET. It acts like it is, but I can never see the SSID.
Try Barnacle Wifi Tether, it is working great for me.

Try this hopefully it works. I am getting my SGII today and this is main reason for rooting...

Does 4g work when you tether?

Barnacle did not work for 4g on my Evo so it may not work now. I believe it only handled 3g

[Q] Wifi Tether Issue: What the hell. Your phone takes back control over the Wi-Fi

Running 2.3.3, rooted, stock ROM. I am having this issue with MULTIPLE versions of WiFi Tether, but currently trying out 3.2 (I think) beta.
Works as expected, but after about 2 minutes or so, tethering stops, and I get the following error:
"What the hell. Your phone takes back control over the Wi-Fi interface."
It's only on screen for like 2 seconds, so I can't reproduce the entire message.
It appears that the phone turns on it's Wifi, which seems to stop wifi Tether. I am having trouble finding this exact issue on the Internet.

well i have no idea how to fix your problem but i do know that you are in the wrong forum. this should be in the Q&A.

Turn off your wifi before you use wireless tether.

Thanks for both responses. I wasn't sure which forum to post this in as I didn't know if it was an issue with the EVO, the Android version, or WiFi Tether.
I have since un-checked "Restart WiFi driver" and also checked another setting that keeps the screen from turning off.
One of those two seems to have done the trick, because WiFi Tether has been running for around 4 hours today. I'm using it with my laptop now.
Thanks again!

Forgot to mention, I also wasn't sure about whether or not wiFi was supposed to be running for this thing to work or not. Now I know!
Also, I specifically used the error message in the title because when I searched, I couldn't find anything. Now anyone else experiencing this issue should find this easy - I hope.

This helped immensely. I was getting the same error message searched and found how to fix it here. Thanks leebo!

Not sure if I mentioned this, but I also run "locale", which I set to turn WiFi on in certain locations around town. I have to remember to turn locale off when using WiFi tether, otherwise it turns on my WiFi and tether gives the error message.

There was a certain version of Wifi tether that worked great and I could tether to other devices even if my phone was connected to Wifi...it worked on my evo and evo shift, it was versions 2.2 or 2.1, I don't remember but whichever version of wifi tether is closest to that is the one that worked fine for me

What the hell! Your phone takes back control over the wifi-interface. Immediate tethe
For me the problem was that I had "Sprint Connections Optimizer" enabled. Once I unchecked that box, I could run wifi tether without any errors!
Setting Location: Settings --> More Settings --> Mobile Networks --> Connections Optimizer --> Sprint Connections Optimizer
Phone: Samsung Galaxy S3
ROM: FreeGS3 v3.0.0.0

Yes but....this is the EVO 4G and theres no such option in settings

SOLVED
On my Galaxy S4 SCH-I545 (Verizon branded) unlocked, rooted stock VRUFNK1, on Straight Talk (Verizon network), this worked for me:
Install the Xposed module named "X Tether", also known as "Moto Tether".

[Q] Missing WI-FI thethering after ICS T-Mobile Upgrade

So I upgraded to ICS 4.0 for T-Mobile few days ago. Now I lost the wifi Tethering icons. Tried to recover them from my backup using Titanium Backup, but they are not coming back up.
I went into settings, more, Tethering and mobile hotspot and turned it on...but now it auto redirects me to Tmobile sign up page for Tethering when I try to browse the web.
Any work around this besides re-flashing it with a custom ROM? I already rooted the phone.

Use Titanium Backup to freeze or uninstall the tethering provision .apk (I uninstalled it myself).
Works like a charm. If it still gives you issues, make sure the device that is tethered is not browsing using Chrome.

yeah what he said ^^^
i would suggest backing it up before you uninstall in case you have any problems though.
Happy tethering

When I froze it or uninstall it and go into settings, More, tethering and mobile hotspot, the word "error" appears under the mobile hotspot option. I can't even turn on the mobile hotspot feature without having the tethering provision being turned on. Any other ideas?

Don't use the function on the phone. Freeze tethering provision and then download an app that let's you tether.

Bluetooth tethering, requires hotspot?

I was playing around with settings tonight and discovered Settings -> More Settings (under Data) -> tethering. Checked it, paired my phone and my Win7 PC, initiated an "access point" connection from the PC, and suddenly I was browsing while using my phone as an access point. Granted it was 3G speeds, but it did work.
Does this work for me because I have mobile hotspot, or is this a feature that shouldn't be working, or does it work for everyone? I'm not rooted, using the latest software update (with multiview). I can't even remember far enough back to when a carrier would have ever simply allowed bluetooth tethering, not even Sprint. It's a nice feature to have since WiFi radios usually wear batteries down faster.

this will work for anyone the only thing differnet for people subscribing to hotspot and those who dont is the ability to wirelessly tether with hotspot. hopefully soon we anyone rooted at least will be able to use free wifi thether

Interesting, thanks. I'm still surprised Sprint would allow this considering they offer unlimited data.

That's weird. I just tried this and I got an error 67, registration failed. Maybe they "fixed" it in the software update.

Are using a Galaxy Note 2 on Sprint? Your image tag says you're on AT&T.

Sprint has unlimited data on the phone data only. They have separate plans for hotspots.
2GB @ $19.99
6GB @ $49.99

I wasn't talking about hotspot. I was talking about Bluetooth tethering, and asking if it requires hotspot to work, because with unlimited data you could tether with bluetooth and theoretically have unlimited internet on your PC through your phone.

Can you tether via wifi? There is a wifi tethering app. You can find on xda or PM me and I will email it to you or post a dropbox link.

wifi tether app jb 4.2.1

I was wondering if anyone knew of a wifi tether app that works with 4.2.1?? the built in wifi tether app does work for me all the time

Many roms have tether built in so no app needed. Not sure of any apps that work for 4.2.1

I'm on a Gnex lte with a verizon unlimited plan. I'm running CM 10.1. the rom's hotspot shows up to connect, can't connect with my laptop, can connect on the ipad but dns error and no internet. WiFi tether app, both from playstore and beta3 version doesn't seem to broadcast a signal recognizable by either my laptop or the ipad. I'm wondering if the app just isn't working right or if verizon is blocking my tethering.

I have the the same problem. And my tablet connects to my phone no problem. So just because your laptop connects, doesn't mean the Xbox will, because mine won't. The problem is specifically with the Xbox not working all of a sudden when trying to tether using native or the tether app on 4.2.1. I hope somebody can find a solution soon because I love the new OS and really don't want to revert back.

i have spent two days trying to resolve my issue with wifi tether as well. i've tried 4..2.1 aokp (w/ stock kernel) and CM10.1. with both i've tried using wifi tether with my windows 7 laptop, to no avail. i have tried using open, wpa and wpa2. wifi tether does not work for me with any 4.2 roms. i finally gave up and went back to using my aokp build 5 where native wifi tether works normally.
**I found that Bluetooth tether works, but at an obvious sacrifice of bandwidth speed. wifi tether still does not work.

I'm on AOKP 4.2.1 for Galaxy S3, i747. Same thing, no wifi tethering.
"everyone" keeps saying it will work when there is no encryption, which yes.. others can connect to the network, however, they cannot run data/speedtest.
if you download the wifi tether app for root users ( WiFi Tether for Root Users
Müller, Lemons, Buxton )
it will have troubles starting and configuring AP.

I am having the exact same problem with mmuzzy image 4.2.1 on the Verizon Galaxy Nexus. I did find that svtp - lite tethering app works but 14.99 for the pro version no way.

Same issue on stock 4.2.1 takju. My tablets connects to my phone but can't get internet access through my phone. Used to work fine but ever since 4.1.2 its broken.

Have you guys tried "Hotspot Toggle Widget" by Fattin? I have seen reports that it still works with 4.2.1, but can't confirm it myself since I am on 4.1.1 atm.
The app does not provide hotspot functionality per se. It is a widget to toggle the built-in hotspot on and off. It bypasses the annoying carrier check if you have tether plan or not (for those of us that are still enjoying grandfathered unlimited data).
The app also does not require root.
Google Play link: https://play.google.com/store/apps/details?id=com.fattin.togglewidget.hotspot

wifi tether (native) now works on my phone after 4.2.1 aokp build 1 and build 2 did not work. again aokp 4.2.1 mr1 build 3 has a working wifi tether.

I too have had problems with numerous roms and tether. Just today I installed AOSPA 3.0 on my toro and guess what?
NO WIFI TETHER. Everything else was awesome but I have to have tethering when I'm at home.
So, I roll back to my trusty old CM 10.1 01/02/13 nightly build that runs great and has WORKING wifi tether. Good luck.

I know this doesn't help the OP but I just have to THANK YOU for this suggestion. The " Hotspot Toggle Widget" by Fattin along with Foxfi and PDANet works wonderfully on my Verizon Gnex stock unrooted. So, I know its only 4.1.1. We'll see if we ever get 4.2, but in the meantime, this is way better than only being able to connect my Nexus 7 with Bluetooth because of the carrier check.
