The new games console seemed to be having trouble getting a network connection. Every time it power cycled, it couldn’t connect. Eventually I nuked the router to factory settings, and installed its latest firmware, and also reset the console (using the nifty factory reset but keep installed games option), and now everything seems to be working ok.
Kept working on the rollcage, but the green paint was a mistake. Spent a bunch of time stripping and sanding it off, and now trying to paint white.
