additionally, if start tether first and then start wifi, tether is showing the 
like its 
still working on android, but my laptop no longer can use the connection (stops 
working) and/or disappears.

The "Don't disable wifi" option makes only sense if you use bluetooth for 
tethering.
If Bluetooth is not checked this option has no impact to the startup-procedure.

This means ... if you want to tether via wifi, the wifi-interface has to be 
restarted
(to bring it in adhoc-mode). It's possible that other apps can't handle such 
restart.

re: harld.mue
"if you want to tether via wifi, the wifi-interface has to be restarted"
do you mean tether start will always kill (to restart) existing wifi connection?

"It's possible that other apps can't handle such restart."
I get same results if I don't use Wefi, but start wifi from Settings --> Wifi
wifi gets killed on tether start and not restarted. If I start it manually 
after 
tether is started, tether connection stops working (the tether app shows as ON, 
but I 
can no longer use and/or connect to it.)
btw, I tried this on cyanogen all 4.0.1 through 4.0.3.1

I have the exact same problem with Sapphire 1.0 on Droid1.  Tethering used to 
work, then suddenly started killing the wifi when turned on.  It seems like an 
app conflict, but haven't changed anything since it was working.

any advice

Guys you can't be on wifi and tethering over wifi. There is only one wifi radio 
in your phone, it can't be a hotspot and be connected to a wifi connection at 
the same time... there is no point to it if it did work... can;t you just 
connect whatever is using wifi to the same wifi your phone is connected to????? 

You can connect to wifi when connecting using Bluetooth because the bluetooth 
isn't already being used...

The wifi tether feature is meant to tether your 3g/4g over wifi... not tether 
your wifi over wifi.. it just doesn't work. its not a problem with the app.

If they are talking about the issue I'm having, it's not trying to do both at 
the same time, rather, AFTER tethering is stopped, the normal WiFi will no 
longer start. In fact, no matter what I do, as long as the tethering app is 
installed, built in WiFi is not available once it's stopped the first time. 
Option in phone's settings accepts click, but never checkmarks and starts WiFi 
again.

Only way I've found to get it going again is to uninstall the tethering app. I 
tried the "leave WiFi state alone" setting but no joy.

Hope this can be resolved because you've made an awesome app here.

I agree, I am using 2_0_8_Pre1.  After I have used this program a single time, 
and then disconnect (even restart the phone so the program is no longer in 
memory), I can not turn on the Wifi on my phone to connect to a network.  The 
only way my phone will allow me to connect to a hotspot after I have used this 
program a single time is to uninstall this program.

I had a similar problem but in reverse. I had to reboot the phone when turning 
wireless tether off normally to get it to work again.

Now if I push the home button (leaving wireless tether on) then enable wifi I 
get a weird error, the it turns off wireless tether then turns off the wifi.

Maybe try turning off wifi before you start wireless tether, then kill wireless 
tether by turning on wifi.

On samsung fascinate using v3_1-beta2.

Starting with experimental version 111, if I turn on tethering, my Samsung Epic 
Touch 4g's wifi will not turn back on after I turn off tethering.  A hot boot 
doesn't solve the problem either.  A full reboot is needed.  I have reverted to 
version 110.  I had duplicated this bug in 111, 112, and 113.

Comment 5 is correct: Turn on your MOBILE or 4G setting. The app itself now 
controls the wifi signal.

Comment 6 - exact same issues as mine.

GSM HTC Hero Stock Android 2.1 and VillainRom13 both experience the problem. 
This problem has existed for some time with this app, it needs attention.

I have galaxy s 2,   and its rooted. Tether works fine and I can connect to it 
with internet access. But when I turn off tether and try to enable wifi on my 
phone, it does not work at all, even after reboot. But tether still continues 
to work. This is a very serious problem as I must be able to use wifi on my 
phone at work.

We have the exact same issues as post 6 and post 13. We have a rooted Samsung 
Exhibit II T679. Unless we un-install the WiFi Tether app, we can not use WiFi 
even after disabling WiFi Tether access. A re-boot does not help, only 
un-installing the app gives us access to wifi again.
