GL-AR300M - No WAN DHCP on boot, have to replug WAN cable

Hi team,

I’m having some issues with my GL-AR300M. When booting with WAN cable plugged in, I cannot get IP address allocated via DHCP. I have to disconnect the cable and reconnect to get it to allocate IP address. I’ve tried upgrading to v4 just now but still same issue.

On the DHCP server side I can just see continuous DHCPDISCOVER and DHCPOFFER. I have also tried to SSH into the GL router and running udhcpc -i eth0 manually but also doesn’t work. Only workaround is to replug, but that’s annoying, is there any fix for this?


What’s the isp? Are you connecting to a modem or router to ar300m?
