No, wired connection to the internet via Spectrum, using my own cable modem and my own wireless router. Tried installing using the standalone setup. Same results. Arg!
Also looked at the update services. Oddly, there are two of them. Brave and bravr, both described as update services. Of course, neither one will run manually without a remote procedure call, so my attempt to start one failed. I am at a loss as to what to do next.
