RBS350 Satellites Won't Connect to RBR750 Router

Life got in the way so this is a much overdue update. The solution was to give my laptop a static IP, connect the satellites to my laptop via a USB-to-RJ45 network adapter, and manually load an older firmware update from before my problem started. Once I did that, the satellites loaded up and connected to my router without issue. In order to prevent the router from redownloading a more current firmware update that would recreate my problem, I blocked some Netgear domains (frw-update.netgear.com, updates.netgear.com, and firmwareapi.netgear.com). This unexpectedly had the effect of blocking my browser's access to any and all netgear-based sites, including this community. I'm fact, I'm having to make this post via my cell phone and it's 5G connection until I can figure out how to block firmware updates without also blocking community pages.
