Hello there,
I am having troubles with the hotspot.
When I turn it on, the laptop recognize it but it doesn't have internet connection. Once it was working properly. I thought it is some firewall problem from my laptop so I have tried with another devise ..same thing..if I wanna use the connection for another device ..I cannot even if it say it is connected.
Help please !
