RK3588 as a Soft Router: Dual 2.5 GbE + OpenWrt, Tested at Home
x86 mini PCs used to be the only answer on a soft-router shopping list — until power draw and noise gave everyone second thoughts. RK3588 changes that: four A76 cores push enough packets for nearly any home network below multi-gig.
Throughput reference numbers
- OpenWrt NAT: dual 2.5 GbE ports saturate at 2.35 Gbps with headroom;
- Plugin load: Docker containers (ad-blocking, DDNS, tunnels) alongside NAT keep CPU under 30%;
- Idle power: 2-3 W for the whole unit — about one-tenth of an x86 soft router’s yearly electricity.
“One box, two jobs” is the killer feature
Unlike dedicated routers, RK3588 also carries 8K decode and an NPU — it can serve as the living-room media center (mini PC form) by day and switch to OpenWrt as the main router when needed, or run permanently as a side-router + NAS + downloader combo. Multi-partition eMMC booting makes OpenWrt/Debian dual-boot a reboot-menu affair.
Advice by player type
Want “it just works”? Get a dedicated industrial unit like the RT28 — three LAN ports + Wi-Fi 6 out of the box. Love tinkering and want All-in-One? The RK3588 mini PC with dual boot is the most flexible option in its price bracket. Firmware and flashing guides are free in the Hugsun Documentation Center.
