OpenWrt’s Packet Steering: When It Actually Helps
Packet steering can relieve a CPU0 softirq bottleneck on multi-core OpenWrt routers, but /proc/interrupts measurements should guide the setting.
A Clean OpenWrt VM Design for Proxmox VLANs
Separate firmware, virtual hardware, and VLAN decisions to build a reliable OpenWrt router VM on Proxmox, with OVMF, virtio NICs, bridges, and trunks.
Build OpenWrt Access Points Without Wireless Mesh
Ethernet backhaul turns OpenWrt mesh nodes into simple access points; this guide covers bridges, VLANs, roaming, DHCP, and checks to avoid loops.
Auto-Replace OpenWrt Kernel Config Without Losing Changes
OpenWrt generates kernel config from layered fragments, so this guide shows how to edit, persist, and verify changes without losing them on clean builds.
OpenWrt eBPF Kernel Setup: Which Options to Enable
Build OpenWrt with working eBPF support by enabling the right kernel symbols, matching options to XDP, tc, tracing, or BTF, and checking JIT support.
