Wow I totally hit enter waaaaaaaay too soon, super sorry.


There is a long standing bug apparently over 3 years old, from even the openwrt on this device.

I am able to confirm that the fix from comment #8 @ on the old openwrt ticket 18680 does indeed solve the issue.

The issue is pretty painful, upon rebooting, or loss of power just on the LEDE device, it is unable to acquire a new/same ip from dhcp. Restarting the modem alleviates this issue but is obviously a total walk around the actual issue.

Moving the ports and swapping the wan/lan ifnames across completely solves this issue. The device reboots, grabs its old IP and all is well in the world
