I own two Android devices: an Acer Iconia B1-730HD tablet and an LG G2 smartphone. Both devices are running the Android 4.4.2 OS. Neither device will access the internet while using Public wi-fi. When using public wi-fi both devices show connection to with excellent signal strength. I can find no security or privacy settings that eliminate this problem. I tried a total reset of the tablet, and have turned off, and even uninstalled my AVG antivirus software. Nothing works. As soon as I return to secured wi-fi internet accessibility returns. Does anyone have any suggestions on how to deal with this problem?
