What steps will reproduce the problem?

Change Passphrase = <Changed to new passphrase>
Change SSID = <Changed to new SSID>

3.Stop tethering.
Tethering stops normally.  4G disabled.  WiFi disabled.  4G enabled.

4. Start tethering.
Start tethering dialog hangs at Please wait while starting...  4G disabled.  
WiFi does not enable.  Occasionally, Error 128: Unknown Error. Sign in 
failed...  appears.

What is the expected output? What do you see instead?
WiFi tethering should restart.  WiFi tethering hangs.  Occasionally phone will 
freeze, requiring battery removal to reset.  Phone must be power cycled in 
order for WiFi tethering to work again.

Please provide any additional information below.
WiFi tethering will start and stop successive times if 
WiFi-driver reload = <UNchecked>.  However after a restart, clients may or may 
not be able to connect to the hotspot, or if connected to the hotspot may not 
be able connect to the Internet.  Manually turning off WiFi forces the WiFi 
tethering app to the stopped state. Restarting tethering restors normal hotspot 
activity.

Well. I'm sorry to say but this is a known issue. I've wasted many hours so far 
to find a solution for the epic and other samsung devices but no go ...

You could try to activate and deactivate wifi manually before trying to restart 
tethering ... but yeah ...

Anyways. You could try to change the setup-method to "adhoc" in app-setting but 
this gives you adhoc and not infrasstructure mode ...
