Device: D-Link DIR-867 HW:A1
Software: openwrt-21.02.1-ramips-mt7621-dlink_dir-867-a1-squashfs-factory.bin

Reproducer:

  • Install OpenWRT on the DIR-867.
  • Set the system configuration to defaults.
  • Reboot.
  • Wait for a DHCP lease on the WAN port.

I only ever got this message with a timeout and zero bytes inbound:

udhcpc: sending discover

I tried these things:

  • Running udhcpc at the console with various options like -T, -C and -B.
  • Doing ifconfig up/down on the WAN interface.
  • Toggling every DHCP option in LuCI.
  • Disabling the firewall.

The ISP is Teksavvy through a Technicolor DOCSIS modem. Any other DHCP client works as expected when directly connected to the modem. Reverting to stock D-Link firmware version 1.30 resolves the glitch.
