Saw this too "Installed the latest 11/20 build and can confirm the WIFI re-connection issue. Fell back to 11/18, which seems to run perfect.
Maybe it's the fact that my phone is a Sprint GS3. I do see many GS3 owners having the same issue. "
I don't know if the Note 2 has issues with the 11-20 version or if it is only the SGS3. If there are any issues..I would consider trying the 11-18 version.
