dmuhamedagic:

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.

I can confirm that I had the same issue with this device and version.
As a temporary solution until a fix is out and since I had access to the terminal from WiFi, I used fw_printenv boot_part and fw_setenv boot_part to turn back to openwrt

Don't know if it's the exact same issue, but I ran into something very similar on my WRT1900ACS going from 15.05.1 to lede-17.01.4. Ethernet interfaces' config seemed fine, but could not connect on WAN or LAN side. Had to revert to 15.05.1 using "off-and-on 3 times" method.

I get quite similar problem, and i can reproduce this problem for Bananapi and X86-64 devices for v18.06.0

If i chenge network setting to DHCP then i can get connection for all ports!
