As stated, I’m trying to set up a NAS that plays nice with Spectrum-provided hardware. I’m not the home owner, and the home owner will not budge on using a third-party wifi router that would just act as an access point. I’m trying to set up a small NAS that my friends can access via VPN connection, and I would remote desktop into for administrative needs. I considered Windows Server, but I wouldn’t be able to have it connected to the internet while I set routing and remote access settings, so something that can pick up a DHCP addrese on its own.
Spectrum will provide a modem only and let you use your own router and AP, but if they won’t budge on anything regarding it that’s probably not an option.
What exactly are you trying to accomplish though? What will your friends being doing with your NAS? Spectrum doesn’t have great upload speeds so at best they’d get slow downloads and at worst it would make your internet unusable with them maxing out the upload.
