Wired Cat6 Ethernet connection half speed of 5ghz wireless

[Seanw3490]

I apologize if this is in the wrong spot. I am new here and signed up specifically to get information on something that makes no sense to me. I recently purchased a new 4k Samsung smart tv and I also upgraded my internet speed from 30 to 100mb/s. My router is dual band and on the 5ghz at night I routinely get speeds of 110-130mb/s on both testmy.net and speed of me (ranked two most reliable on google). I decided to get a hard wired Ethernet connection which I assumed would keep my speeds more constant and reliable for the 4k content. I purchased both a 6ft and 50ft cat6 cable. The shorter one is for the modem to router then the 50 ft from the router slot 1 to my tv. With the wired connection I am averaging 50-90. I even switched back and forth at the same time doing the speed test on both sites wired than again wireless (5ghz). Could someone explain why I am getting half speed with a wired Ethernet connection?  Makes no sense. Thanks.

probably the length of wire. idk, i may be wrong. can you not move the router closer to the tv?

Are we talking about over the internet or locally?

[JoostinOnline]

Your speeds are based on the slowest component. A CAT6 (or even CAT6a) cable will only run at 10mbps if one of your ports is CAT3.  Most likely one of your ports is rated for 100mbps.  It could be the TV or the router.

The length generally does not affect the speeds, unless you are pushing it beyond 50ft.

[Seanw3490]

Would just like to add that anyone thinking user error or speed fluctuations is incorrect. Did it late at night, no other internet traffic in the house all apps on the tv closed, and I ran the test 4 times alternating wired with wireless. 

Wired 65-85

Wireless 110-125

Cat6 is good up to 1GB/s. If anything it's overkill. I only needed a cat5e.

I see some wrong info here. Firstly Cat 5e and Cat 6 are rated for 1 Gbps up to 100 Meters or 320 Feet or so. My guess is a device in the chain has 10/100 Ethernet ports, either the router or TV.

Please see my previous comment.  Also tell me the router model.  That might help determine the speeds.

[Seanw3490]

Also can't be the tv considering the test I ran was on the tv for both wired and wireless and I alternated. 

First went into network settings and used the wired connection. 

Then went into network settings and used the 5ghz wireless 

I went back and forth each time running the speed test twice before switching back

I did it made no sense. Cat 6 is good up to 1GB/s

That doesn't matter.  CAT6 is capable of gigabit speeds, but the devices in between need to be able to send and receive at those speeds too.  If one of them doesn't, then it will go to the lowest speed.

although I don't know what that has to do with the wired connection being slower than the wireless

The cabling isnt the issue. Some device makers stick  10/100 Port on their routers or TV's because they can save a few dollars.

I understand that. The modem is good up to 300mb/s. and then a Cat6 to the router and then a Cat6 to my tv.

I'll have to check the specs on the router then if you think that is the case.

I mean either way the 4k content is coming through just fine.  When I watch something 4k on Netflix I can hit info and it shows the speed build to 15.26mb/s on the stream 2160 (wired or wireless) that's the exact speed the 4k content streams at on Netflix every time. 

It was just confusing me that I was running slower with the Ethernet connection.

You aren't understanding.  The Ethernet port on the TV is probably only capable of 100mbps.  It's not uncommon.  Like @Donut417 said, they do it to save money, because almost nobody uses wired anymore.  If the NIC built into the TV is only rated for 100mbps, it doesn't matter if you've got a damn fiber optic cable running between them.  Also keep in mind that these are theoretical speeds.  That's why you aren't always getting a steady 100mbps speed.

 

Please don't dismiss our explanation. It does make sense.  It's very frustrating when someone asks for help and rejects the answer.

You were misunderstanding. I wasn't rejecting your answer. I thought you meant the port on the router would only allow 100mb max not on the tv. I meant no disrespect. I do apologize. I was answering an earlier reply when you had said that.

cat 6 is rated at over 150 for just 1000mbs so that doesn't make any sense.

Is this over the internet or local between a NAS and your device?

 

[Seanw3490]

I was answering the reply when you had mentioned that everything in line had to be correct by saying that I made sure the router and modem both were capable of those speeds. It never crossed my mind that the tv LAN input would or may be limited. I appreciate the responses.

In my home I just my internet through my dual band router at 5ghz is on average 110-130mb/s but today I ran my Cat6 cable from the modem to the router(6ft) and another Cat6 from the router to the tv(50ft) and the wired connection is only averaging 80mb/s. 

 

my tv is a Samsung mu6300 55" if that helps.

It could have been the router, but I checked and yours is gigabit capable.  I went through something very similar awhile back.  I used to have a router that could transmit 300mbps over wireless, but the built in ports are only capable of 100mbps.  Wireless is faster than wired, unless you're very far away.  I upgraded my router to a nicer one, only to find out that one of my computers had the same problem.  It could transfer 400mbps wirelessly, but only 100mbps over a wire.

 

Things are only as fast as your slowest component.

Gotcha so if my router is gigabyte capable then it must be the LAN port on the tv then.
