You might want to try removing that program just to see. Also i have had issues off and on until i realized it was my wireless router, so i unplugged it and let it sit for a few minute and powered up and my issue was resolved.

 

exactly the same as the OP, and i'm running stock. i've reset and wipe cache and pulled battery and reboot. it's fine for a while but resumes again after a while. hard to repeat because it doesn't happen every time. when it does happen, i just wait for the 'Error' message to come up (which can take up to a minute while it hangs), then go through the main settings to restart wifi.

this started after the EC05 froyo upgrade for me.

 

This is a known issue with the 2.2.1, on the Epic. Hopefully it gets fixed with an upcoming update. I'm having the same issues with my wifi connection.

 

So do we know what triggers this hang up?

 

My Epic does the same thing. Such a hassle to have to reboot my phone to get the WiFi working again, only for it to lose connection and not be able to reconnect unless I reboot again.

 

Has anyone found a solution for this? Why is the Samsung Epic 4G so buggy? At first I thought it was the ROM that I'm using, but to hear others with stock Froyo to also have this problem.... grrrh! I'm definitely not getting Samsung for my next Android phone.

 

yea i get this error too. what i usually do is turn on 3g, try to turn on wifi, then turn off 3g. and that usually does the trick. maybe turn on airplane mode for a second or two might help.
