i setup my samsung vibrant for wireless tether, my laptops connect without any problem but my tmobile galaxy tab won't pick it up. seems like the wireless tether is invisible to the tab.... anybody can shoot me a fix? thanks!
I believe the Tab, as with all Android devices, doesn't see ad hoc networks. Wireless Tether uses ad hoc. Only 3G Mobile hotspot on VZW uses true infrastructure mode. There are hacks out there depending on the type of phone you have.

thanks for the advice! after i swapped the wpa_supplicant, it's working now
How do you swap it out? I found 3 files with that name. 2 of them have .conf at the end of their names.

Thanks for bearing with me here guys I really want to get to the bottom of this..that said let me give a clear explanation of the problem
I used z4root to root both my EVO and my Galaxy tab so I can use the wifi tether app to avoid the addition $30 a month fee. I've applied the change to the wpa_supplicant file in the Tab to allow the Gal Tab to see WiFi and I am using the WiFi tether app (which it does see) This is where I have the problem- although my Gal Tab sees the signal coming from my EVO it won't connect to the EVO....When I try to connect it says "Obtaining IP address from AndroidTether(adhoc)" .....it's trying to get an IP address from my EVO that it cannot seem to obtain. So here is my 2 part question:
Is there a difference between the way unrEVOked 3 and z4root root my EVO and would that difference between the way these root the EVO possibly be the reason the Galaxy Tab won't connect to the EVO with the WiFi tether app?
Thnaks guys for your patience.
I finally got to the bottom of this problem,...today the Wifi tether app developers updated the app addinginfrastructure support for the EVO. This completely solved the issue.
I know with my Xoom I had to flash a patch to get it to connect to my tethered Thunderbolt, is it possible to use the Galaxy yet? Or is there a patch? I saw one for ADHOC in the 10.1v forums but wasnt sure if it worked for 10.1
Yes it does. Try it out. Don't forget to turn on airplane mode before following the procedure.
On a side note you might want to post this in the Q&A section, not development section. Especially since one week ago I posted a topic saying that it does in fact work - l2 search before posting.
Some people say that if you have the latest version of WiFi Tether on your phone that the Tab should see it. So try that first. However, my tab could not see it so i had to do things the old fashioned way.
If you are in the same boat then you need to replace wpa_supplicant which is in system/bin with the one from the xoom (search for it, there's a link to it somewhere in the Galaxy Tab 10.1 forums. that's because the Tab's wifi driver filters out Ad Hoc wifi servers (which your phone is). You will need Root Explorer or some other file manager for root users. Here is a quickie tutorial
0) make sure your tab has regular wifi access before you start this process
1) Get the wpa_supplicant file from this thread (look at the bottom of the first post)
http://forum.xda-developers.com/showthread.php?t=1083182&highlight=wpa_supplicant
2) Unzip the file and get the wpa_supplicant file which is in \system\bin of the zip
3) On your phone go to \system\bin using Root Explorer and copy it to somewhere on your SD Card.
4) Copy the new wpa_supplicant file that you unzipped in step 2 to a folder on your tab's sd card
5) Turn on R/W access in Root Explorer
6) Replace the wpa_supplicant file in /system/bin with the new one
7) Final step VERY IMPORTANT - change the permissions on /system/bin/wpa_supplicant to be rwe
8) Reboot tab
9) Verify that you still have traditional wifi access
10) Turn on WiFi tether on your phone
11) Go into wifi settings in setup and see if your tab can now see Android Tether
This seems like a pain.. mine worked out of the box. Granted, I have a custom rom on my galaxy S (ATT Captivate).. using the built in Mobile AP in the settings. No external app required...
An access point is an access point (whether it is your phone or your router), why would the GT not connect to any access point?
I can tether with my captivate.

Because an access point is not an access point. There is a big difference between ad-hoc and infrastructure mode. Android won't connect to an ad-hoc network. And my OG Droid along with other, older Android phones won't do infrastructure right out of the box.
Last I checked, while Access points do have support for Ad-Hoc, that is not the primary purpose of an AP. Ad-Hoc is generally a non service providing device to device.
An Access point by its very nature of being an AP does so in infrastructure mode. I do realize that I may have jumped the gun as many of the older devices do not support functioning as a true AP, rather an ad hoc network with a proxy running in the background to proxy data.

Yes, it is a pain. But if you are using certain older phones (Android 2.2 or older) that do not provide infrastructure wifi then you are forced to make the Tab recognize ad hoc and out of the box the Galaxy Tab 10.1 does not.
I am glad for you and others who have had it easy. I suggest that people try to wifi tether the easy way first, without changing wpa_supplicant. But it is a method of last resort which is better than nothing.
Windows Phone to tether 10.1
So from what I'm reading on the forums, it seems most of you have android phones and are using them to tether to the 10.1 after rooting. I have a crappy windows HTC HD2, it has wifi router on it, but like everyone else the tab does not recognize it. I was hoping that this WiFi Tether thing, I assume it's an app? Will work if I get it. Any experience trying to accomplish this and give me the warm fuzzy if I happen to pursue installing and going through the root process that is already posted, that it will work? I'd much rather try getting this WiFi Tether thing than go through and root the tab.

Wi-Fi Tether is an Android app for phones, so I don't think it'll help you unless you put the Android ROM on your HD2. So you're gonna have to root and follow the directions posted to get it to work.
Use Barnacle Wifi Tether
Just use Barnacle Wifi Tether in the Market
...works like a charm with rooted Captivate and 10.1
My Milestone running CM7 connected just fine (first try!) using 3G Mobile Hotspot that comes bundled in CM7. Great speed too.
I haven't tried any other wifi or USB tether app.
New At This!
Hey all, Loving my GTab at the moment except for the inability to tether it to my iPhone. This is a new arena for me. I have been jailbreaking each of my iphone versions since the first but I have never had a Android phone before so no idea how to root it. The steps listed on the first page of this thread, are those the steps you have to follow AFTER you have rooted the phone? If so, I am assuming everyone has had success at rooting the 10.1 tablet so far. I ask cuz I would never tell my friends to jailbreak their phone cuz if you do not know what your doing you can screw something up. I dont want to fall into the same category. I am going to do a search for rooting in Galaxy Tab 10.1 but figured I would first see if those directions are all I need to know. thanks in advance and sorry if I missed any post that already has this info in it.
I asked you this in your other thread, but it's probably best placed here:
iPhone 4 or 3GS?
I don't think the 3 can create and infrastructure hot spot, only ad-hoc which takes rooting to connect to. I could be wrong about that though as I'm not an Apple guy.
If you have a 4, TetherMe is an app that should allow you to create an infrastructure hotspot and your 10.1 will connect to it. You won't have to root if you go this route.
Or you can just get a Nexus S 4G like me with infrastructure mode out of the box...

I have the newest iPhone4. I use PdaNet right now because it allows me to hide my usage so that AT&T can't be A-Holes and take away my unlimited data usage. I am not sure it has a Infrastructure hotspot like TetherMe does so I will check it and let ya'll know. Thanks for the help so far!

Ok it seems that PDANet doesn't have the infrastructure hotspot but fortunately TetherMe allows tethering on any APN that is used for iphone data. So the hide usage feature from PDANet seems to have been ported over to TetherMe so I am going to give it a whirl and see what we come up with! Too bad I paid for PDANet a while back! LOL
============================
Installed and tethering perfectly without the need to root! VanSmack my man...Madd Props! However, I should note for those with iPhone4 looking to do this, I ran into a snag along the way. I am not sure why but TetherMe crashed during the middle of its install and took me about 10 mins to get it rebooted, purge of the half install and installed again. I am not sure if My3G and/or PdaNet conflict with the install of TetherMe or if it was a random glitch, but I uninstalled both of them and reinstalled TetherMe and it installed like a charm. Simple easy and connect. Thanks again everyone!

TetherMe now supports all iPhones from iOS 3.x up to iOS 4.3 so you should be able to use the same software I installed to tether your GTab. However the easiest way to check it is to go into cydia and find TetherMe and see if your device supports its. I would post a link but i'm a newbie thus its inactive.
As I understand it, the iPhone 3GS wifi chip does not have infrastructure mode coded into its firmware. Thus I don't think TetherMe will fix that problem, but my recommendation would be to try it and find out. Again, I'm not an Apple guy, I've just played around with others phones and that's what I discovered.
And no sweat, stat. Glad to help.
I have an HTC Hero(rooted) and my wife has the Samsung Epic 4G(rooted). I have tested both phones with the same WIFI Tethering app and the Galaxy Tab recognizes and connects to my wife's phone...internet wifi works just fine.
When I test it on my HERO...the Tab will not recognize the HERO at all. I know that this works just fine with my laptop. I've tried the wireless tethering app and still no luck.
I have the wireless tether app V. 2.0.7 and the WiFi tethering app V. 3.0...no luck on neither one of them. Wondering why it works fine with my wife's phone and not mine. There was no need to modify anything on the Tab for it to recognize the Epic...but no luck on the Hero.
Any ideas????
I know it can be done.
Thanks in advance.

Search this forum and the Development Forum for Ad-hoc Network support.
The gist is this - your phone (and most older phones) only provides an Ad-Hoc network to tether. The galaxy tab requires infrastructure mode to tether and will require a few fixes that are provided in a thread in the development section to work with Ad-hoc networks.
The Epic will provide infrastructure mode which is why it works and the Hero does not.
The issue is most likely that the Galaxy Tab 10.1 does not see/connect to Ad hoc networks, which is probably what your phone is broadcasting. If your Tab is rooted. Check out the link below. I followed the directions from the first post and am not able to tether to my iPhone (had the same issue as you prior).

My tab is not rooted yet, but I will do soon enough. Just a little afraid to do so right now. I've rooted quite a few phones so I'm confortable doing that. Just need to read a little more on how to root the tab. I'll take a look at the link you provided and hopefully I can get this thing to work.
Thanks

That's what I thought as well, but my Tab will not recognize my HTC Hero(yes it's an old phone) but my laptop recognizes it with no issue. Hero and Epic 4G have the same wifi tethering app and Epic connects with no problem, but my hero will not. Damn, I want this thing to work.

That's exactly what my Droid was doing. The new build of wifi tether didn't work for me either. Changing the wpasupplicant (I think that's what its called) fixed it instantly and now my tab can see all ad hockey networks like my phone and printer!

The Nexus S 4G will allow you to tether 3G or 4G using most of the apps in the market such as Wireless Tether or the built in hotspot app (3G only), but these methods turn your NS4G into an Ad-Hoc network. Some devices, my notebook computer for instance won't accept an Ad-Hoc connection so I found another (Simple IMO) method.
Some background:
My brother has an Evo 4G and he has never had any issues tethering to my notebook computer using 4G so I wanted to find out why. Turns out Evo's use a different method of tethering. They do not broadcast as an Ad-Hoc network they use a completely different method of tethering called "SoftAP". This essentially makes Evo's think they are actual Access Points, which any wi-fi enabled device can connect to.
I found a way to make my NS4G work in this manner using the WiFi Tether app, very similar to the Wireless Tether app in the market.
Prerequisites:
MUST be rooted.
Make a nandroid backup ( better safe than sorry)
Have some time to toy with the settings if the ones listed below don't work (which they should)
Download and Install attached file "WiFi Tether for Root Users 3.1-beta6" on your NS4G and grant SU permissions.
Open app and go to Settings-> and change to the following below:
Change Device-Profile: Samsung Galaxy S
Change Setup-Method: Netd (Master)
Once you change those settings you will be able to tether as an Access Point and not as an Ad-Hoc connection allowing you to connect and tether your 4G with pretty much any wifi device.
You may have to play around with the different variations of the options but the ones I have given above should work just fine.
**One thing I should note, the only issue I've had with this is set up is when you stop the connection. The app might "Force Close" and on occasion reboot the device. But that is a small price that I pay to tether my 4G connection.
Let me know if this method works for you just so I can confirm it wasn't a fluke on my end!
Hope this helps anyone with similar tethering issues.

Wireless Tether is blocked for us 4G users on the market. The last version that I was able to download from the market was 2.0.7 and it didn't include the softAP option. While I never have had a problem running in ad-hoc mode it's good to know the app has been updated since 2.0.7, thanks joesloco for the heads-up.
btw your instructions worked for me I was able to connect with 4G through an actual AP instead of an ad-hoc network.

As far I know, the 4G switch/widget is broken in this version.
When I turn it on from settings, 4G scans for a while and then it says disconnected. Does 4G work with Cyanogenmod? Any patch required? Or should I replace with a different ROM?
I'm in a major city that has Sprint 4G coverage.
How could I get 4G tethering working?

Great guide. I forgot all about this when I used it on my optimus.
I heard that this is faster than the native one. Is that true?
