CAT 6 (34 meters) only giving 400 mbps (50 mb/s) [HELP]

[ajgamer1]

Hello, I have installed Cat 6 inside my house with the length of 34 meters approx. and it is only giving 400 mbps which is 50 mb/s.

 

But I guess, It should give 10 GBPS or so based on the information shared on internet about it.

 

But I am not even getting anything as 1 GBPS.

 

Brand/Manufacturer of Cable: D-Link.

 

Brand/Manufacturer of RJ-45: D-Link.

 

Router: ASUS AC68U  (Gigabit Supporter)

 

Please advice me over here.

 

P.S.: CAT 6 is clearly written on the cable.

 

Thanks.

Are you testing local speeds or download/upload speeds that are dependent on your ISP? 

[Sir Asvald]

That's correct.. 400/8= is 50

I have tested this with the setup this way.

34 Meters Ethernet from a 1 GBPS Ethernet Port Dell Laptop to ASUS AC68U and A WD My Cloud to the same Router.

 

So basically, I tried transferring multiple files from My Cloud (WD NAS) to my Dell Laptop.

 

It only gave 400 MBPS or so. 

 

It should give something near to 1 GBPS or so.

I'm not sure, What you are referring to. But question is, Why CAT 6 is only giving 400 MBPS when it should give something like 1 GBPS.

I'm not too knowledgeable about this, but surely if there is a hard drive in the NAS or Laptop, that will slow down bandwidth? If both were SSDs maybe it'll go faster?

Is the My Cloud also wired via ethernet too? Can you

Even a slow 5400rpm HDD should be able to sustain 80-100MB/s~.

probably because the drive in your laptop or my cloud is slower than christmas

[FloRolf]

Obviously you don't and will not get 10gbit because of your PC and Router. 

 

But what are you referring to? From where to where are you measuring?

Of course, It's wired with Gigabit Ethernet only to the same router.

 

Also, When I check the copying and pasting from my nearby system of like 2 meter length wire. It gives 800 MBPS or more. (Which is very near to 1 GBPS).

Your connection will be only as fast as the slowest connection in the chain.

Cat6 may be rated for gigabit speeds (1000Mbps/125MBps), but if you are connecting to the worldwide interwebs with a connection from your ISP that only supports 20 Mbps, you wont go over that speed.

So like others asked, how are you testing this?

He is referring to MB vs. Mb and how you are using them interchangeably which can cause confusion.

The small or large 'b' in sizes refers to completely different things.

1 MB = 8 Mb, so keep this in mind when referring to the speeds you're getting.

in the best case scenario yea but think about older laptop drives and it not being a single big file, that could slow things down

it could be that your cable is of VERY poor quality if it slows down that much from 34 meters

do you have the packaging or the place where you bought it from?

Maybe you bought a shitty wire. I can get over 100MB/s out of my 100 foot Cat 5e run.

It is D-Link CAT 6. D-Link is bad?

It shouldn't be, but CAT 6 at 34 meters should get you the same speed as a 2 meter cable. So if you get much better performance between the two devices with a shorter cable, then the problem is the cable.

How can I check for the problem? Is there any way you can help me with diagnosis?

 

I checked this with the Dell 3460 Laptop.

 

If you want, I can try checking the same laptop with the 2 meter wire to rule-out.

 

Please.

Run the Dell laptop and the My Cloud both with short cables and then also in whatever configuration you want them to be in (with whatever length cables you'll use long term). And make sure to use the same file(s) for testing.

I checked with a 2 meter CAT 5E Cable.. Dell and MyCloud both on short cable connected to same router.

 

It came as 90-120 mb/s (avg. 108)

 

What's your diagnosis now?

I agree. I have seen poor quality Cat6 only give 60% throughput in GigE and some testing with Cat7 with el-cheapo cables at 40% throughput. Plus GigE hates multiple connections. It's better to have a continuous run of copper than using couplers.

Be careful with your letter capitalisation. You're using Mb/s and MB/s interchangeably. It's difficult to know what speeds you're actually getting if you're using different abbreviations for the same units or vice versa.

So you average 108 MB/s (864mbps) with short cables and 50MB/s (400mbps) with long cables while doing the same transfers (in the same direction -- always writing to and reading from the same device)?

 

If so, then there's a problem with your long cable(s).

I'm not sure if MyCloud devices can do this, but I know many other NAS system can be directly wired to a PC/laptop, so with a cable you know work you could check what speeds you would get and than try with the longer cable to see if you have any difference.

If the longer cable is (noticeable) worse: than it's the cable. If not: than the router hinders some performance.
