Why is my Intel Centrino Ultimate-n 6300 AGN Driver repeatedly disab

Im using Windows 10 :[.

It randomly n repeatedly disables my internet.

At times i show ‘Available Connections, yet No available Wifi.

That is Troubleshooter only tells me the obvious.

Your ethernet is not plugged.

That would make sense when im sitting at The Coffe Shop wondering why i have a choice to manually turn on wifi. (Why was it turned off)

The drop down says.

Manual

Restart in 1 hour

Restart in 1 day

Etc…

What are thes choices and why are the here instead of “Choose Wifi conecction".

Thank You.
