LG OLED C9 - No Internet via Ethernet


Recommended Posts

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.

      Each year, millions of home appliances reach the end of their operational lifespans and are taken away for disposal.* However, their story doesn’t have to finish there. Through transformative processes and technologies, these discarded devices can be reborn as brand-new appliances, offering features and performance tailored to the needs and preferences of today’s consumers.
      Let’s explore how old appliances are being turned into up-to-date and environmentally-conscious living solutions by one of the leading innovators in the home appliance industry.

      Urban Mining: Unearthing New Resources From Discarded Appliances
      ‘Urban mining’ means extracting valuable resources from ‘retired’ household appliances. It involves recovering and sorting any raw materials that can be used in the creation of new products. Unlike incineration – a fate that befalls many disused appliances – this course of action helps reduce carbon emissions and prevent environmental pollution. An active urban miner, LG extracts several different materials from discarded appliances – including plastic, iron and non-ferrous metals – and then uses them to help produce its advanced, new offerings.

      LG Recycling Center: Giving New Life to Old Appliances
      Since the end of 2021, LG has been implementing resource circulation programs in a total of 52 countries worldwide as part of its extensive efforts to combat greenhouse gas emissions. At the LG Recycling Center in South Korea, which commenced operations in 2001, raw materials are harvested from disposed-of home appliances, meticulously sorted and processed before being made into ‘fresh’ eco-responsible appliance components.
      Here are the four main steps taken at the LG Recycling Center that make it possible to turn old appliances into high-quality parts for new products.

      Step 1: Collection – Used appliances such as refrigerators, washers and air conditioners are collected and transported to the center.
      Step 2: Disassemble and Crush – The appliances are taken apart, and the components are crushed to achieve a consistent size.
      Step 3: Sorting and Processing – After iron, aluminum, copper and plastic materials have been sorted, the plastics are put through an additional process where they are made into pellets; a convenient and renewable resource for the manufacturing of plastic parts and goods.
      Step 4: Rebirth – The pellets are melted and transformed into plastic parts for use in the production of new LG home appliances.

      Recycled Plastics: Giving Life to LG’s Captivating Designs
      Recycled plastics play an important role in bringing the captivating designs of LG’s home appliances to life, including those of the recently launched LG Styler ShoeCare and ShoeCase. The LG PuriCare AeroFurniture air purifier and the LG tiiun mini, which come in an array of vibrant colors to enliven the home, also employ recycled plastics. Used in the construction of both products’ exteriors, these repurposed materials contribute to the aesthetic appeal of LG’s innovations and help reduce resource consumption and waste.

      A Continuous Virtuous Cycle for the Planet and Consumers
      LG has fully embraced a ‘Sustainable Cycle’ approach, building eco-consciousness into every stage of the home appliance lifecycle, from production and packaging to usage and recycling. The company continues to utilize recycled materials extracted and processed at the CRC in the manufacture of new appliances – appliances that minimize power consumption and emissions, and are themselves highly recyclable. In this way, LG has created a virtuous cycle that simultaneously benefits the planet and consumers.
      Stepping up its efforts even further, LG plans to reach a cumulative total of 600,000 tons of recycled plastics (for producing home appliance components) by the beginning of the next decade. The ambitious target is set out in the company’s ‘Better Life Plan 2030,’ and also forms part of LG’s broader strategy to achieve carbon neutrality.

      Also by 2030, LG estimates it will have recovered 8 million tons of out-of-use appliances for the purpose of extracting recycled materials.

      By implementing initiatives such as proper product disposal and the extraction of materials from discarded products, LG is able to create something new from something old, showing how a firm commitment to people and the planet can help make a better life for all.

      I  have just bought an LG TV (model LG 43UQ7500). I have tuned it via antenna, but the TV has a problem playing everything (it says "invalid service") except for 7 channels, which are public broadcast (but that shouldn't make difference - they are all DTV). The only thing that does help is turning off the TV, waiting for a few minutes and then turning it back on. Once I turn it off and then on, it stops working - except for the 7 channels. So it's a neverending process of turning it off and on to actually be able to watch the TV. 
      Does anybody know what could be causing this? The TV has been updated, I have set it up for my location (Czech Republic), I've tried factory reset....
      Thank you for your suggestions!

      It is easy to add a new item to the quick settings side menu on an lg c2, as long as the item you want is shown on the list presented when you choose  the + add item.  If you want to add a "shortcut" to an item that is not on the list then how can that be done.  Is it possible to edit the list presented?
      Specifically I want to add a shortcut to "subtitles on" which is buried deep in accessibility settings,  there nothing on the list of options presented to allow this.

      I recently updated the firmware on my  LG43UH610V.  Now I constantly get "Wired Lan cable disconnected" / "Wired network is connected" messages even while watching a video file from my NAS. The TV is connected and using the network while getting these messages. It has always been on a fixed IP address on the LAN.
