Laptop disconnects from Iphone hotspot
I run a Dell Latitude E5440 laptop and a iphone 5SE
My laptop will detect a wifi router and provide good connection to the net.
When I try to use the hot spot on the 5SE, the laptop can wee the iphone and will allow me to go the next step of putting in the iphone password.
After a second or two I get the connected advice and then half a second later to laptop disconnects.
I have tried rebooting both. I have tried removing the iphone profile using the control panel.
I get the same result what ever I do.
The iphone will run as a hotspot to an ipad, all ok.
There must be a setting somewhere I am not seeing.
Can anyone help?
Thanks
iPhone SE, iOS 11.4
