I have the annoying problem that Wi Fi appears to be working -- as in, I get a signal indicator -- but I get Unable to scan for networks

 

Or, at least that’s what was happening for the last 14 months.

 

I did a number of tweaks trying to connect to a network, but without success.
I finally did a factory-reset, wiping out all of my apps - but still couldn’t connect.
So I assumed it was the radio chip.

 

Just tonight, I realized, or noticed, or had for the first time (I hadn’t actually used it since the wipe, since everything was gone) that the signal indicator was present.
that meant that the radio was working.

 

So, I went to settings, turned on wifi, scanned... and no soap.
Tried again... only, I went into Wi Fi settings FIRST.
Enabled Wi Fi from there, and my local network showed up almost immediately.
WTF ?!?!?!?

 

However, while trying to re-establish my google account, the Wi Fi connection was lost, and I was unable to replicate a connection.

 

 

WAAAAAH!

 

 

An attempt to manually add the network fails with the error [@Unable to save the network@[

Was having the same problem (came across your post from a Google search).

 

I got a hint from code.google.com (can’t post the link). I renamed the /data/misc/wifi/wpa_supplicant.conf to /data/misc/wifi/wpa_supplicant.bak (rather than delete it), rebooted and all is well.

 

Unfortunately, I can’t even find that file
