Samsung TV - no network cable detected

Ismailk — Sat, 22 Aug 2020 10:50:26 GMT

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've Model QE65Q8DNATXXU which was showing exactly the same Issue - even though the 'work around' solution was working fine over WiFi. Using the cable Wired Connection, Streaming Apps would occasionally disconnect/stop working which was very frustrating and unsettling (due to the unpredictability). The disconnected/reconnected Ethernet message appeared on-screen.

I tried everything including replacing the ethernet cable into the TV's Ethernet Port, resetting my TP PowerLine Adaptors (to get the Ethernet Connection extended to near the TV using the house wiring) and checking my Router Settings etc etc.

Only by chance did I come across the Solution under a different thread on this platform; it looks like the root-cause is the category of Ethernet cable used. The cheap-as-chips '5e' causes the on-board Ethernet card in the TV to 'misbehave'.

I bought a 1m length of the latest Cat 8 cable (along with 2 more to connect Modem->Router->PowerLine Extender) and ever since it's been fine for the last 5 days😀No Ethernet-related on-screen error messages and no dropped App connections. I appreciate Cat 8 is over-kill and Cat 6 is known to do the job - but Cat 8 is the latest and fastest cable. One of the reasons for this Post is to confirm Cat 8 and to reinforce that it's the Category of Ethernet Cable which appears to be the root-cause.

Hope that helps - and thanks to the person who originally Posted elsewhere.

I've had the same issue and also got a Cat8 cable but that didn't sort the problem. Anyone else got this issue?

Hi Bill,

In a word 'no' 😞

It was better for a while and then the same error message re-appeared. I'm using Cat.8 over a TP Powerline Adaptor (has performed well previously so n reason to believe this is the route cause) from an ASUS gateway router (which is excellent btw).

Solution: after trialling between Wireless and Wired (via TP Link adaptor), I've moved permanently to WiFi. No issues whatsoever. I struggle with this because, historically, the reverse 'wired is best' was always true 😐

Analysis: There's an issue with the on-board Ethernet Card; clearly a nightmare to fix! Probably explains why Samsung aren't admitting any liability - especially when WiFi is an acceptable (to me) workaround.

Hope that helps? Any Q's, give me a shout on here 🙂

Many thanks for that help. It's just happened since I changed router I believe but I agree with you on the work round.

...you're welcome. There are so many people with this issue, meaning there's a large range/variety of end-user hardware being used e.g. routers, extenders etc. that the single, shared link is the TV hardware. No good news but a nightmare to fix for the. manufacturer.

Seriously??? The onboard ethernet card's don't work??? And Samsung don't have anything to say??? I've remade a Cat6 cable 5 times trying to solve this problem, and now we learn it's actually their card??

Hi Laurence, Like you I’ve spent ages on this. It’s more frustrating than “It doesn’t work” as it’s intermittent in my experience. Seems to work ok for a while and then unexpectedly throws the on-screen error message. I’ve given the only reason to explain this that I can come up with (and I’m an IT person with solid networking skills!) Easiest answer is go to WiFi. At least the card in this Model includes both 2.4 and 5 bands👍

Hi - Thanks for your reply. I've been using it on wi-fi since I got the set. No problems. Except I'm a Virgin Media customer using a third party router attached to VM's modem. Like most people, I have a house full of devices with their own wi-fi networks as well. Sometimes, especially evening, the wi-fi just doesn't cope as well as you'd hope. Connection clash. So I was hoping that hard wiring might take my main TV off the wi-fi and give it stability. Optimistic, eh!

I had a similar issue. The TV always said 'Network cable not found'. I connected to the router and enabled Layer 3 port for the LAN1 port (which is used to connect with the TV) and it worked.

Hi Laurence - thanks for this. Unsure what you mean by 'a house full of devices with their own wifi network'; do you mean 'devices connecting to the same wifi network(s) (typically 2.4G & 5G)? My advice is to consider investing in a new router. The tech has advanced in terms of your wifi speed not being restricted by the speed of the slowest device on the wifi network (MU-MIMO). I'm a long-time fan of ASUS Routers running Merlin's Firmware. Just a thought.

Thanks for sharing this. The issue I - and many others - have is the intermittent drop-out over ethernet. So it's not 'server works' or 'always works' it's unstable. I tried to use mine Samsung over a Powerline Adaptor plus Ethernet to the TV; I can't connect the TV directly into a router Port. Further, on my ASUS AX88U Router there is no option to configure LAN Ports as you show. Which Make/Model of Router or LAN Switch (?) are you using? Also, what does that enable over-and-above the standard protocols used by wired Router Ports?

Thank you alooooot you saved me ! It even worked on my Sony TV 2019 model with cat 6 only diff my TPlink AX11000 calls it IPTV enabled so I just enabled this option where the tv cable is connected and voá-la working 100%

I have exactly same situation on my new QE85Q60TAUXXU. All internet cables in the house are cat 5. Samsung e-manual states the use of cat 7 cable. This is difficult to understand as the network speed in UK is generally very slow, less than 100Mbps, a cat 5 cable is more than enough to handle. Just as I am about to buy cat 7 cables I read this article. I may change my mind to get the cat 8, just in case I buy another TV in the future with similar requirement. It is not a simple change of one cable, it may involve a few. I still worry that the cables used by the builder between the source node and each room may be of a lower grade. Hope the TV is not that intelligent. Thx.

I had the same issue with QN85 4K Smart TV where it would not connect to wired connection (wireless was fine). I have CAT5 ethernet cable & I acknowledge the manual states to use CAT7 shielded. I did not want to run a new CAT7 wire under the home etc as this would be a project. I have a Unifi Network that allows much customization so this solution may not work for all. I went into the Unifi Controller GUI for the Unify LAN switch device & changed the "port profile override" for the PORT "line speed" to be "100/10 Mpbs FDX" and then it worked. The default for the "line speed" was to "AutoNegociation" and this seemed to be in the way. If your "router/switch" allows you to "hard-code" the line speed protocol, maybe that will work for you. Hopefully this will continue to work long term and I will not have to change out the line to CAT7.

How did you get to this screen and do this?

Unsure what you mean by 'this screen's. Can you please expand your description if you want people to help/feedback?

Samsung TV model 2021 (AU7700 smart tv 4K UHD, 55 inch). Was tearing my hair out why the new TV kept saying cable not plugged in. After changing to CAT7 cable, it works. So yes, TV won't take CAT5 cable. You need the higher quality cable. One possible way to "trick" it is to put a network switch with your CAT5 cable with internet, and then CAT 7 from switch to the TV. I will try this because my CAT5 cable was laid through the external wall. So not easy to replace. Can't figure out why they need this CAT7 because CAT5 can go up to 100 MBits and Netflix 4k HD requires 25 MBits.

Thanks for sharing this; I went for CAT8 from my Router and then into the TV. It initially appeared to work but then the original intermittent 'drop-out' re-appeared. Can you please update us on if this is a permanent 'fix' for you? If it is, then it's maybe my TP Powerline adapters! :-(. Tbh, fortunately the WiFi is great in our house so my alternative WiFi Connection is fine.

Yup it's working.. atm I've hooked the cat 7 cable from TV into the mesh device, which is a gigabit port and then that communicates with another mesh device (wireless) before going into the main router. Been watching few movies on Netflix since. Is it possible your router port can't take gigabits?
