after that I downgared it back to 2.3.6, and I could not turm it on back again

When turn it on, the wifi shown searching later 10-20 seconds it turn off by itselve.

When you upgraded, and then downgraded, did you do a factory reset?

I would download and install Kies from the Samsung website and backup all the data you need. And try a factory reset.

This seems to be a pretty common problem with the upgrade from GB to ICS. It sucks to lose all of your apps, but a functioning phone is better than no phone.

I returned to the GB and still the same problem

Any apps you downloaded from Google Play should automatically re-install when you first sign in to what used to be called the Market, so I'm not really sure how you'd lose them. Same goes for Amazon App Store.

I can't say for sure as you have done all the things I would have done. If the WiFi is still acting up, is there any way you can bring it back to your carrier or send it back to Samsung?

I have done a little reading on the issue, and it seems with the upgrade from GB to ICS screwed up a lot of things, namely WiFi as far as I have read.
