Severity - Critical

Due Date - Undecided
Details - Yesterday I upgraded the Linksys wrt1200ac from openwrt 15.05.1
to lede-17.01.4. The upgrade was done through a luci web
interface.

After reboot the wan connection was gone, as well as all local
ethernet ports. Wifi continued to work fine. The configuration
seems to have survived the upgrade. I couldn't find anything
wrong with the configuration.

On the Internet port there were no packets coming in. On the
ethernet port 1 there are bootp/dhcp requests coming from the
router.

Not sure if that is relevant, but reverting back to 15.05.1
didn't work either: the router is currently completely
inaccessible. I don't have a serial cable, will probably order
one to try to debrick the thing.
