Its been a few weeks now since Android 2.3, a.k.a. Gingerbread, was delivered to my Google Nexus One mobile phone. I had been experiencing terrible problems with the WiFi reconnecting to known networks, and randomly dropping off networks it was connected to. This was most frustrating; dropping back to 3G data is expensive, slow, and sometimes becuase of this, I disabled it which meant no data. All while sitting within 10 foot of my WiFi AP.
It appears that this is no longer a problem, ever since the Gingerbread update was installed. Yay! Thanks for the fix, Google Mobile team.
