Hi MarcosCampos5
If you get a Network Credentials popup, you should be able to turn off that requirement . . .
On the PC you are trying to access, open Control Panel
Go to Network and Sharing Center
Select Change advanced sharing settings in the left pane
Expand the network you want to disable password protected sharing on by clicking the down arrow on the right of the profile
Select 'Turn off password protected sharing' and then click Save changes.
