Windows 10 private network
I have tried all the Microsoft instructions as well as many on-line help sites and can't get the network to work properly.
i have three computers. They can all see each other on Windows Explorer. Computer A is connected to the router via ethernet. The others use WiFi.
A printer (Brother HL-1440) is connected to Computer A and can be used by Computer B but not C.
Computers A and B can access each other.
Computers B and C can access each other.
Computer A can access Computer C but C can't access computer A.
I no longer care about sharing files but I do want to be able to print from each computer.
Ideally, I would connect the printer to the router (TP Link Archer C50) but it is incompatible.
