Discussing the networking features of a USB-C to RJ-45 adapter versus a software-based router implementation on hardware is quite different. The former focuses on physical connections and standard protocols, while the latter involves digital processing and routing logic within a device. Mobile wireless networks fall outside this scope when considering wired communication standards. Your point about routers with multiple connectivity options is clear—using a dongle bridges the gap between standard adapters and full router functionality.
