It seems I have to wire my laptop to the router in order for both to see the same Homegroup. Yet even then the laptop cannot open any of the shared folders on the desktop. I read some posts on the internet that said it was due to the Verizon wireless router needing an update. I worked with the Verizon tech support and they said it was not the router but they could fix the home networking problem with a purchase of their extra tech support. Figured I should try Dell first. The desktop is a Dell Studio XPS. The laptop is a Dell Inspiron 13 5378. Both are running Windows10.
Thanks for the link but I've followed that process several times. The problem is not creating a Homegroup. The problem is the wireless laptop does not see the wired desktop and the wired desktop does not see the wireless laptop. Therefore, the laptop cannot join the desktop and the desktop cannot join the laptop. I have a little success when I wire the laptop to the router where I can then see and join the desktop but still all I can do is see the desktop shared folders but cannot open the folders to see what's in them.
Ok, then please perform a systems diagnostics test by pressing F12 at startup, then make notes of any error messages, and contact Dell Tech Support.
