  1. Hi. I own C9 for ~2 years and I've been using it wired to my network. Lately I've moved to a new place and I'm unable to connect it to my home network using Ethernet cable. In short: TV doesn't get IP from dhcpd. When I provide IP manually it won't connect also (but is listed on UniFi Cloud Key device list with that IP. Seems like Ethernet interface is not brought up by TV). DHCPD is run on the router which is a pfSense device. When I connect TV over Wifi - it successfully obtains IP from the very same DHCP server. I've looked into dhcpd logs on the pfSense and when TV is connected via Ethernet cable, it casts DHCPDDISCOVER, gets DHCPOFFER from the server, but then never casts DHCPREQUEST to get DHCPPACK. So I see DHCPDISCOVER & DHCPOFFER loop in the logs. I've been suspecting there is another dhcp server in my network that LG TV is sending DHCPREQUEST to, but this is highly unlikely and I've enabled dhcpd guarding on the switch just to be sure. In terms of hardware, comparing to my previous apartment I have a new switch here (Unifi) and new in-wall cabling (Cat 6a). I doubt switch and cables makes a difference here. TV firmware is the latest. Connection is OK (I've checked it with a network tester). Network port is OK, standard LAN VLAN. I've doublechecked everything and running out of ideas. Any ideas / tips how to diagnoze and solve this issue? I'd really like to have it wired instead of wirelessly connected.
