On my Droid 2, I go to
Settings/Wireless & networks/Wi-Fi settings/Manage Networks (at bottom of list).
On that screen it says "To conserve battery, delete un-necessary networks from the list."
Great advice -- but how do you do it?
I went back to the Wi-Fi settings screen; long press on an unwanted network -- the only choice is "Connect to Network".
I powered off the phone. Waited awhile. Powered back on. Same result. I have the latest Motorola maint applied.
Any ideas?
