Hi Guy, believe it or not the first try was MS Help. They recommended downloading updates. I do go to the garage but there are people who can usually fix. You referred to "Multiple times a solution is given here". Fine. Multiple times different solutions. For example "remove driver and reinstall" - If I remove the driver Windows automatically reinstalls the latest one. For another example: "reload old driver" - On MS download sites one can only access the latest versions. I found an archive of old drivers, tried to install and the system does not let me do so stating that I have newer version on the disk. I am honestly not an IT specialist, just would like to use my stuff for what I bought it. I also believe in the voice of the customers and thought that at forums like this it could be made heard. Windows 10 is far from ready. If You just can tell me how to reinstall 8.1, that may be fine. That at least worked with the wifi. Thanks for trying anyway.
