Wifi Tethering help

I recently bought a used HTC Hero(Sprint) and I can't get the device to be seen as a hotspot. When I turn on WIFI tethering it is ony detected as a peer-to-peer and not a wifi hotspot. What is wrong any help would be appreciated.
What program are you using for tethering? The app that seems to work best for us Hero users is Wireless Tether for Root Users. It isn't available from the market, so you'll need to Google search for it. There are multiple versions available, but the one that seems to work best is 1.60 for the hero.

That's the only way it works. Ad hoc only. Sucks if youwant to use a wii, but works with computers, iphone, etc.

I am using the 1.60 version of Wireless Tether for root users. My friend has a EVO and it does not pick up the signal at all but my work laptop does but admin rights don't allow peer-to-peer connection
then you might want to try usb tethering with easy tether or pdanet
I found version 2.0.5 pre3 test 3 at the google code site. I was able to get my hero into infrastructure mode with it. My DS still won't work with it but my laptop does connect to it as a wifi connection instead of ad hoc. I am also able to change the SSID with this version but encryption still does not work. Haven't had a chance to look into those issues yet.

[Q] How to make wifi tether work with 3g Tab

So my rooted Tab comes with unlimited 3G connection, tried several wifi tether apps from the Market and my HTC Desire Z doesn't seem to detect it. Is there a compatability issue here?
Hopefully I can get it to work so I can save money by being able to use wifi tethering from my Tab to my CP. Thanks
Google wifi tether and got this, hope it helps.

Tried the Google wifi tether app, it installed fine and seems to be working but my cellphone(Desire Z) still cannot detect any wifi signal. =(
I think that PDAnet will also work fine, if I'm not mistaken.

Tethering

I just got a Streak 7, and new to this whole tethering stuff. I was wondering if someone can help me with something. Can anyone guide me on how to use the streak 7 with my Tmobile Samsung Galaxy Smart phone to tether my connection on my smart phone to use on my Streak 7. Please help. Thanks
You would have to have tethering on your smart phone. Don't need it on the s7. Your s7 will pick it up via wifi. So just have wifi enabled on your s7 and wifi hotspot turned on on your phone. Assuming you have this feature, just tap menu>settings>wireless&networks>tethering&portablehotspot and then check wifi hotpot.

I do not have the wifi hotspot feature. I have Barnacle app, but that is a ad-hoc network. Is their another way of getting this to work.

So, ad hoc does't work? I was reading through wpa_supplicant on the Streak7 system dump, and it looked like they tried to get it to work (could be wrong; I'm about as n008 as you can get with Linux).

They might help. Then again, they might not. Backup and install, then let us know!

Problem w/wifi tethering after install Gingerbread

Hi Forum,
I cannot get my Sprint tab to see my phone after installing Gingerbread. My computer can see the phone and connect it, but the tab won't. Before Gingerbread, I was able to scan and connect to my phone and tether just fine. I tried diff. wifi tethering app. Currently use Barnacle. My tab is not rooted, but that should not be a problem.

I was in a hurry! Fixing the wife issue is going to be a lots more difficult.
my galaxy tab brick after falsh
which version of GB do you have installed? Is it the stock sprint update? Have you tried the WPA supplicant fix for it yet?
I using Sprint OTA Gingerbread, 2.3.4. Build number EF17. I have not tried the WPA supplicant fix. I did not have problem with this issue on Froyo. I will research on this. I would like some tips if you got them. Thank you !
I found a link on the issue, but require root. I am reluctant to take this step. It is not that I don't know how to use Odin, but removing root is a pain.
Here is the link to WPA supplicant if any interested.

from everything i've read, you won't be able to connect to ad-hoc mode wireless (most wifi tether apps) without the wpa supplicant patch. you might look into a wifi tether app that will do infrastructure mode to get that working again.
@ pvtjoker42,
Thank you for the tip. I did some further research and the Wifi Tether app works in infrastructure mode too. If any one interested, here is how you do it. Choose device profile- I chose Samsung Galaxy S. I also tested Samsung Galaxy Indulge. Under Setup-Method, choose Softap ( master). Now your Samsung Tab will see the phone. This app drains battery like no tomorrow, much more than Barnacle.

I am not great guru on these phones (or any for that matter). I have similar situation. Had an Evo4G that would wifi tether after root. This phone (Desire 510) seems to have additional guards. After installing the 3.0.3 of the wifi-tether apk there is a message that appears in the log indicating the phone takes control of the wireless ethernet interface after tethering has started. This kills the wifi tether.
I haven't identified what process is block the wifi tether but there is one called tetherguard. Mine is a Sprint phone so tether is available at a fee. The phone must be capable.
