Your connection is not private? Someone might of took your connection so bạn can't use it now. Someone probably used 'Airplane Mode' instead of 'Wifi' so they probably used YOUR connection so it's not private :O

Maybe bạn can try yahoo.com it works similar to google.

bạn should use wow.com. It's very similar to Google.

try bing search, that's all i use.

also, it could mean that your connection has been compromised, bạn should try changing your settings hoặc adding a mật khẩu to your internet.
