Nexus One, cleared internal user storage to near-factory settings using the boot menu. My computer is connected to wifi, and I have a USB tether to my phone.
But when I click on "Connect to wifi" -- even in the virgin "user setup" menu -- No networks are found, and the device becomes unbearably slow.
The device had functioned properly for 1.5 years ... until yesterday.
I don't know whether the problem is hardware or software. If it is in software, I would like to fix it... but I don't have wifi, and I don't have 3G.
What are the steps to diagnose this problem?
If it is a software problem, what are the steps to fix it?
