    Hello, I have a question, can someone help me solve my problem? Well, I have a TV and I want to connect via cable, the computer shows a cable transmission of 200 mb / s, and when connecting the cable from the rotor to the TV is 35 mb / s. What is going on is someone to explain how to make the cable good transmission
    (tp-link AC 1750 router, TV-40 "Full HD Smart TV K5600 5-TIZEN series).

    Help or logical answer

    I separated as a new thread from the archival discussion, although it should fly to the trash for the author's arrogant statements. Unnecessary posts went to the BASKET.

    The most common is a 100 Mb network card - type, model and company nobody knows, because the manufacturer does not provide such information.
    The card is 100 Mb, which does NOT mean that it will "pull" the full 100 Mb.

    See if there is newer software for this tv - it's upload, maybe they have improved it a bit

    Is it the same cable that you tested between the router and PC and Router and TV?
    If not then you have the answer.
    In addition, the accuracy of earning and quality of RJ45 plugs, the length of the cable, the way of laying the cable, power supply systems in the area (switching power supplies etc.), other power cables nearby ... it is so rough.

    Plug in and unplug the cables a few times, check if it fits into the socket and contacts well, are there any switching power supplies nearby? Be sure to update your TV.
    How did you check this connection speed?
    The TV will reach max 75Mbit anyway and if the software is not kicked.
    From what I see it is Samsung and they often connect to some servers without our knowledge. Maybe the TV sucked some updates (there is plenty of it on other forums, they are capricious TV when it comes to the network) ...

    Hmm, why do you need more transfer on TV?
    Programs in UHD quality e.g. from NetFlix are max 20 Mbps.

    I will say I have enigma (iptv) files extracted from the decoder and I want them to run smoothly

    The problem in this case may not be so much the bandwidth of the Ethernet link but the communication between the memory and the network link. TVs are optimized for your needs and the architecture of the supercomputer nobody will put there because of the cost.

Topic summary

✨ The discussion revolves around a user experiencing a significant drop in internet speed when connecting a TP-Link AC1750 router to a Samsung 40" Full HD Smart TV K5600 Series via Ethernet cable. The user reports a speed of 200 Mbps on their computer but only 35 Mbps on the TV. Responses suggest that the TV likely has a 100 Mbps network card, which may not utilize the full capacity due to various factors such as cable quality, length, and potential interference from nearby power supplies. Recommendations include checking the cable used, ensuring proper connections, updating the TV's software, and testing speeds on different websites. The conversation also touches on the TV's architecture, which may limit performance despite sufficient bandwidth.

FAQ

TL;DR: Your Samsung K5600’s Ethernet is likely 100 Mb, and UHD streams need only ~20 Mb/s; "max 20 Mbps" is normal. [Elektroda, sanfran, post #16808400]

Why it matters: This FAQ helps TV owners fix "why is my TV only 35 Mb/s on cable?" issues without replacing good hardware.

Quick-Facts

Quick Facts

Why does my TV show ~35 Mb/s over cable when my PC gets ~200 Mb/s?

Your TV likely has a 10/100 Ethernet port, not gigabit. Real-world 100 Mb links often deliver less than the theoretical maximum due to device architecture and software. So, 35 Mb/s on a TV while a PC hits 200 Mb/s on the same router is expected. Update the TV firmware and retest. [Elektroda, KOCUREK1970, post #16807122]

Does the Samsung K5600 have gigabit Ethernet?

No. Forum experience indicates many TVs, including Samsung models, use Fast Ethernet (10/100). Manufacturers rarely publish NIC models, and 100 Mb ports seldom sustain full line rate in apps. [Elektroda, KOCUREK1970, post #16807122]

Is 35 Mb/s enough for Netflix UHD or IPTV?

Yes. UHD streams from major services use about 20 Mb/s. That leaves headroom for app overhead and brief bitrate spikes. "Max 20 Mbps" is common guidance for UHD. [Elektroda, sanfran, post #16808400]

How can I test network speed accurately on a TV?

Run multiple tests on different sites or apps. One site may misreport speeds on embedded TV browsers. Compare results after each change you make. This isolates server or app issues from your network. [Elektroda, bogiebog, post #16807262]

What quick physical checks should I do on the Ethernet link?

Use the exact same cable that delivered 200 Mb/s to your PC. Reseat both RJ45 ends several times. Inspect connectors for poor crimping. Keep the cable away from switching power supplies and power cords to reduce interference. [Elektroda, lukaszd82, post #16807304]

Could background updates make my TV’s speed test look slow?

Yes. TVs may contact vendor servers or fetch updates silently, reducing test bandwidth. Rerun tests after a minute, then after a reboot. Disable auto-updates during troubleshooting if possible. [Elektroda, lukaszd82, post #16807321]

Should I update the TV firmware to improve throughput?

Yes. Install the latest software, then retest. Vendors sometimes improve network stacks in updates. The OP confirmed running the latest after checking, which is a necessary step. [Elektroda, laudy1, post #16810115]

Why doesn’t a 100 Mb port reach 100 Mb/s in real apps?

Fast Ethernet is the link limit, but TV processors, memory paths, and app overhead reduce throughput. Expect figures well under 100 Mb/s in browser-based tests and streaming apps. [Elektroda, KOCUREK1970, post #16807122]

What is IPTV (and Enigma files) in this context?

IPTV delivers TV over IP networks; Enigma files are channel or stream lists from Enigma-based set‑top boxes. These streams usually fit under UHD bitrate needs, so a stable 35 Mb/s link is generally sufficient. [Elektroda, laudy1, post #16808721]

Can the TV’s internal design bottleneck the network speed?

Yes. "TVs are optimized for your needs," not for high-throughput memory-to-network transfers. This architecture can limit sustained speeds despite a healthy link. [Elektroda, sanfran, post #16808817]

How do I run a fast 3‑step diagnostic on this setup?

  1. Reseat the Ethernet cable at the router and TV several times.
  2. Update the TV software, then reboot and retest.
  3. Repeat the test after waiting, as TVs may contact background servers. [Elektroda, lukaszd82, post #16807321]

Does my TP‑Link AC1750 router cause the 35 Mb/s cap?

Unlikely. The router supports higher speeds. The TV’s Fast Ethernet and software are the limiting factors. Focus on cable integrity, firmware, and background tasks first. [Elektroda, KOCUREK1970, post #16807122]

Is 75 Mb/s the real ceiling for some TVs?

Yes, some users observe around 75 Mb/s as a practical ceiling on TV Ethernet. This reflects app and system overhead more than link limits. That is still ample for UHD streaming. [Elektroda, lukaszd82, post #16807321]

Are single-site speed tests on TV reliable?

Treat them as rough indicators only. Test across multiple sites, then compare with a known-good device on the same cable. Consistency across sites is more trustworthy. [Elektroda, bogiebog, post #16807262]

What is 10/100 Ethernet?

It’s Fast Ethernet supporting 10 or 100 Mb/s link rates. Many TVs use this, not 1 Gb/s. Real streaming throughput can be lower than the negotiated link speed. [Elektroda, KOCUREK1970, post #16807122]
