Has anyone tried to assign a specific DHCP lease to their phone with their router to see if this solves the problem? This is killing me, I have to have a phone with flawless wifi, I don't get great cell signal where I work so I need the wifi for texting (I use google voice) / chat / email. I guess I will know more tomorrow when I get home to get mine. I tried to talk my wife to brining it to me at work but no dice there.
I currently have a galaxy nexus which has very finicky wifi as well. I have found that it is more router related than anything else. With the apple airport extreme the connection has always been perfect, but I saw here this is not the case with this phone. Fingers Crossed.
