Accessing Spectrum Internet Public Access Points

I have Spectrum Mobile for my cell service provider so I can use these access points with my cell phone. I can also use Xfinity access points even though I have no service with them. (Some sort of cooperative agreement must exist between Spectrum and Xfinity.)

I also have Spectrum internet service at my home so I assume I should be able to use these access points with my computer although I have never tried. I know of no other way to use them.
