The shared folder has always been working until I bought a new router. Installed it and then my MacBook Pro is unable to map the shared folder on my Windows 10. I tried to ping the Windows 10 from the MacBook Pro and I received a request time out. However, I can ping my printer and other devices fine but just not the Windows 10 computer. The Windows 10 is able to ping the MacBook Pro but not the other way around. How do I start troubleshooting this issue?
