I need help as my internet connection has failed. I am running Windows 10 and until recently all was fine. After a break of a few weeks I put the computer on to find no connection. An additional problem is my lack of any meaningful understanding of this side of computing.
In Network Connections I have -
Network cable unplugged
Qualcomm Atheros AR8151 PCI-E Gigabit Ethernet Controller (ND15 6.30)
Wireless Network Connection 3
FRITZ!WLAN USB Stick AC860
I have uninstalled the Ethernet controller and reinstalled it to no effect. It is also shown as enabled when I click on it in Network Connections.
In Device Manager both the above are shown as working properly.
Under Wireless Network Connection 3 my modem name is followed by Connected, secured.
In Windows Network Diagnostics I get the message -
There might be a problem with the driver for the Local Area Connection adapter.
Any help would be gratefully received.
