Hi @ricknbeachcrest,

If you can do what you are expecting to do on the Windows Computer, that means that you have everything set up correctly when it comes to the USB settings on the router.

This would leave one of two things, there is some sort of security setting on the router blocking the Chromebook or there is something happening on the Chromebook itself. When looking around Google, I found several threads stating that the native File Manager for ChromeOS has trouble detecting Network Attached Storage and Some File Shares.

Previously it looks like people were using an app from the Web Store that would allow the Chromebook to see the Storage. Unfortunately, this looks like it was removed. As this does not appear to be a setting or problem with the router, I would recommend visiting threads concerned with Connecting NAS (Networked Attached Storage) to Chromebook File Systems. They will have far more expertise on the topic and should be able to help find either a solution or workaround.

If you find a solution that works, please come back and tell us so that we can help create support articles on the topic for other users.
