I've given up on some Windows network things like seeing other PCs in the network window. Sometimes it works and sometimes not.
Just find the IP of the PC you want to see by using Nirsoft's Wireless Network Watcher.
Then in the Network portion of File Explorer type in the address eg. \\192.168.1.24.
If folders are shared on that PC you should now see them. If you want long term access, map the drive.
