TravisRobertsThank you for your quick reply. I tried some port testing software per your recommendation and they all come back with the port is blocked/filtered.

It's far too complicated for me to diagnose, so I'll have the professionals take a look at it.

  marklevinI realize this is an old post, but in case anyone else comes across it: AT&T specifically blocks port 445 over their network, so you cannot directly connect to SMB file shares. This is outlined in this document at the table near the bottom https://about.att.com/sites/broadband/network. By contrast, Spectrum does NOT block 445 (in my experience) but it's hit or miss depending on your internet service provider.
