Setting Up OpenWRT Router as a Dumb AP

2025-05-18

Setup

Follow the steps in [1], and make sure to plug the Ethernet cable to the LAN port of the wireless AP.

Post Setup

WED and HW Flow Offloading

Follow the instructions in the dumbAP router's wiki page, and enable HW flow offloading and WED.

Install bridger to enable WED for the dumbAP:

opkg update
opkg install bridger
reboot

It may not work, however the performance increase is only marginal.

Use odhcpd and unbound for DHCP and DNS

opkg update
opkg remove dnsmasq odhcpd-ipv6only
opkg install odhcpd
uci -q delete dhcp.@dnsmasq[0]
uci set dhcp.lan.dhcpv4="server"
uci set dhcp.odhcpd.maindhcp="1"
uci commit dhcp
service odhcpd restart
opkg install unbound-control unbound-daemon
uci set unbound.@unbound[0].add_local_fqdn="3"
uci set unbound.@unbound[0].add_wan_fqdn="1"
uci set unbound.@unbound[0].dhcp_link="odhcpd"
uci set unbound.@unbound[0].dhcp4_slaac6="1"
uci set unbound.@unbound[0].unbound_control="1"
uci commit unbound
service unbound restart
uci set dhcp.odhcpd.leasefile="/var/lib/odhcpd/dhcp.leases"
uci set dhcp.odhcpd.leasetrigger="/usr/lib/unbound/odhcpd.sh"
uci commit dhcp
service odhcpd restart

QoL packages

opkg update
opkg install luci-app-unbound luci-app-attendedsysupgrade iperf3
