Samsung TV - no network cable detected

[Ismailk]

I am trying to connect my Samsung TV to the internet using a network cable. The wireless option works 100%. However I want to connect using the cable.

I plug the cable in and the light does go on at the tip of the CAT 6 cable but when I connect it says

"No network cable detected. To connect to your wired network, insert a network cable into the TV".

I have placed a laptop right next to the TV and connected the same network cable to the laptop and there areno issues. Also works 100%.

I have reset the settings , been through a software upgrade as well.

What else can I try?

Model: UA55M6000

Software version : T-KTSUABC-1280.5

Hi, I tried various ways to get round this issue. The main point is trying to position your primary router close enough to the TV so that you can get a Cat 8 ethernet cable directly from one of the routers LAN Ports to the Ethernet on the TV. I would say WiFi works fine so it's not imperative to use a cable (especially if you're having issues). That said, depending on how modern/smart your router is at managing WiFi traffic, a cable isn't a bad shout. What I did was a) note the MAC Address of the TV ethernet card b) used this to add that MAC to the router's static LAN IP addresses (so the TV gets assigned the same LAN IP by your router every time you switch the TV on) c) use Cat 8 cables between your ISP Termination block->your router & router->TV d) use the TV Menu to configure your TV to use a Wired Connection then e) use the same TV menu to check the connection details (the LAN IP should be the Static one you applied via the MAC Address described earlier). You connect to the router using the routers private IP Address eg 192.168.1.1 Google it or look at the sticker on the router. Put this IP in your browser and you'll see the router's log-in screen. User Name is usually 'Admin' & the Pwd is on the router sticker. Then you can assign a static IP to the TVs ethernet card. Does that help? It fixed the issue for me. PS Sometimes the TVs ethernet card is asleep and needs waking-up. When this is the case, I get an on-screen error message when opening an App; just 'cancel' and retry opening an App eg YouTube and it will work.

I had the same problem.  The solution is quite simple, and I picked it up from a post buried in one of these chains.  The cable into the Samsung TV port should be Cat 8 and not less than that.  I simply used a standard connector to connect the Cat 6 cable (that runs about 30 feet to my router) to a 2-foot Cat 8 patch cable ($10 or so on Amazon) and connected the other end of the Cat 8 to the TV.  It worked.  (Btw, the Samsung tech people were pretty clueless, and never suggested this.)

Thanks so much for replying.  For me, it didn’t matter that the router is far away.  My set up is router —> 30 feet of Cat 6 cable -> connector —> 2 feet of Cat 8 cable —> TV

I have a long - 30 foot or so — cat 6 cable to my router.  At the other end, I have a small connector that is used to extend ethernet cables.  These are available on Amazon.  I connect the Cat 6 cable to the connector, and the other side of the connector to the short Cat 8 cable.  I connect the other side of the Cat 8 to the TV.  Hope this helps.

If you move the TV with the ethernet cable still plugged in, and you yank on it just a tiniest bit. It literally breaks the ethernet card. That's what happened to me. 😔

I find it annoying that there doesn't seem to be any replies from Samsung support on this issue that many people as well as myself are experiencing.

Has there been any resolution to this stupid AND I MEAN REALLY STUPID ISSUE? You would think paying $1000 for a t.v. and something simple as plugging in an ethernet cable would not be an issue? If anyone has some ideas, apart from those suggested in this thread, it would be great if your "resolution can be detailed step by step. Some of these suggestions can be really confusing for those who are not techies!

And Samsung, if you are reading (and care), can you please spare us the usual canned solution?

Hi, please see my Post of 20-08-2023 to Robert0917 (you can ignore the steps about 'static IP' - that's a nice to have tbh).  Since I put my primary router close to the TV and used a Cat. 8 Ethernet from the Primary Router directly into my SS TV, I have had no issues with the Ethernet Cable-related Error Message for 12 months.  If you can create a Mesh Network with another (secondary) router that should work; I would avoid power line adaptors and the like. I agree that this situation is really poor for a supposedly modern TV.  There's no way SS are going to comment on this as the WiFi alternative is a very  workable option in most cases; the cost to fix millions of TVs (imagine the process even if the Ethernet Card isn't soldered onto the main system board and can be replaced).  PS I tried using a USB-A external Ethernet Adaptor and this wasn't recognised by the TV. This would need some sort of Command Line access to the TV Operating System - which I >>wouldn't recommend even trying<< as this may brick the TV.  Hope that helps.

Hi Ciren,

Thank you for the response and willingness to share your expertise/experience. Here is my setup thus far - very simple and basic from the photos. I have a CAT8 shielded cable (10ft) running from ASUS router to the port of my Samsung t.v model #UN65AU8000.  The distance between my router and t.v (port) is about 6 ft.  This is close enough for t.v to receive the 5g signal which is the current set up. Now,  if you can help me explain what you meant about  creating "mesh Network with another (secondary) router," that would be great.  Does this mean I have to purchase another router?  If I do, do I plug the new router into an available port in my current router?  I have listed your response to Robert and made some comments. 

1. Note the MAC Address of the TV ethernet card How does one find out?
2. Use this to add that MAC to the router's static LAN IP addresses (so the TV gets assigned the same LAN IP by your router every time you switch the TV on). I should be able to manage this via ASUS
3. Use Cat 8 cables between your ISP Termination block->your router & router->TV. This has been completed
4. Use the TV Menu to configure your TV to use a Wired Connection Pending completion
5. Use the same TV menu to check the connection details (the LAN IP should be the Static one you applied via the MAC Address described earlier).
6. You connect to the router using the routers private IP Address eg 192.168.1.1 Google it or look at the sticker on the router.
7. Put this IP in your browser and you'll see the router's log-in screen. User Name is usually 'Admin' & the Pwd is on the router sticker. Then you can assign a static IP to the TVs ethernet card.

My goal is to help provided a guided solution for everyone with your help! Thank you in advance.
