Started happening with me too. Not sure why, since I didn't change anything...

Incredibly frustrating, using JuiceDefender, I'm constantly changing radios and its essentially ignoring my available wifi.

edit: Can't delete post, but it was SubSonic causing problems. Launching it seems to mess it up wifi, even after a force close. Rebooted, wifi was fine, launched subsonic, killed it, wifi broke. Rebooted, uninstalled subsonic, wifi works fine again.

 

Mine just started working again with no obvious changes.

 

Mine does the same thing. ******ed...Why have a wifi toggle on the power control widget bar if every time I click on wifi I have to go into the settings and look for it there...

 

These phones need lotsa clean contiguous RAM to initialize WiFi. Active background apps or even recently closed apps don't help here. Wish I could provide more precise metrics.

 

I've been having similar problems. It all started yesterday when my wifi would not connect when turning it on. I will go into the settings and I still can't connect. I tried forgetting the network and then tried to connect. Still nothing. I have no clue whats going on.

Aside from all that, my phone just seems to be acting a little odd over all. I scanned for viruses. Nothing. I wonder if some app is doing this. Any insight would help.
