LAN Interface problem WRT3200

Since version LEDE 17.01.1 I have problem witch lan interface. Don't bring up. DHCP don't work, routing is dead.
For LAN to work properly I need to add in rc.local this:
sleep 30
/etc/config/network restart
Earlier on LAN all worked well.
Ps. Is this WIFI model at 2.4 GHz and 5Ghz working only at 20MHz channel width?

I just tested with a fresh 17.01 image (17.01-SNAPSHOT r3316-7eb58cf109) for WRT3200ACM. Router boots ok and LAN is present.
Likely your problems have something to do with your network settings.

Working well for me as well.

Thanks for the fast response.
I reinstalled LEDE. Now it works fine. I do not know why I did not want to do it earlier. Three hours I lost.
