I have an Optimus Elite (rooted but otherwise stock), which had been running well. It was connecting to my home wi-fi network as recently as late afternoon today and there were no problems of any sort. Went out this evening and now back at home the Elite tries to connect to wi-fi and says "error." When I click on Wi-Fi Settings, everything is grayed out except for the item to turn on Wi-Fi-- when I click on that, it says "turning on" but after a few seconds it says "Error." All other entries ("Add Wi-fi Network," "Network Notification," and "Wi-fi Protected Setup") are grayed out. It's as if something corrupted the software relating to wi-fi. The phone does connect to 3g data. I've tried power cycling the phone (including removing the battery) but the results are the same. My wi-fi network appears to be fine (e.g., my tablet connects); nevertheless, I did reset my router but still have the same results. Any ideas about how to fix this?
