Can't see computers on Private network after April 2018 Update

Since the April 2018 update, I can no longer see or connect to the other PCs on my home ethernet network. I've made sure advanced sharing and file discovery is turned on on each computer, but still no joy.


This update removed Homegroups, which were buggy and unreliable, but that should have been a networking improvement; now it's like I have no network at all. What am I doing wrong?

 
Solution
The April update also disabled the SMBv1 protocol. That is still used in network discovery. If you google your problem you will see lots of articles on how to enable SMBv1.
