On my most-frequently-used WiFi networks, my Optimus M keeps forgetting my WiFi passwords, forcing me to track-down and re-enter them quite frequently. It then keep the password on-hand for a while, but soon forgets it again (days to weeks later). The networks have unique names, so aren't likely to be confused with other networks I might encounter. Does anybody have any experience with or ideas concerning this pervasive and irritating problem??
