I have a MacBook Air with Corei5 and it is connected to web through a netgear wifi router at home. I am able to connect to the web without any problems but I am just not able to log into LINE using home wifi. I have tested at the Apple Store and was able to log in, just not able to do so at home. Connecting to LINE using a window-based laptop through home wifi has no issues. I have tried to reboot, re-connect to wifi but nothing seems to help.
