My galaxy S2 will connect to public Wi-Fi, but then day no internet connection.

[Android Central Question]

For example. I can connect to Delta Sky Club but no internet despite fact neighbor is connected. I have tried to "forget" network, re-set DNS. No success. Happened with update to system.

Have you spoken to your ISP about it? The update and the WiFi problem may be no more than coincidental.
