Would a 6m ethernet cable reduce internet speeds?

[spencermehta]

I used to have my router in the room I have my PCs. I had them connected up to the internet through the power circuit using adaptors and would get around 60mbps download and 18mbps upload, according to speedtest. Today, I had a new ADSL port installed in another room, which I moved my router into. I'm now running a 6 meter ethernet cable directly from the router to my PCs and am getting 47mbps download and 15mbps upload.

 

I know that very long ethernet cables can reduce the speed but would only a 6m one make such an impact or is it an issue with the ADSL port?

No, they should work up to about 15m just fine, I have one going like half way around my house to a switch in my room and it works fine

Should be good. Bad cable maybe?

[TheKDub]

Strange, it shouldn't be having much of an effect on the speeds, I'm running a I think 50 foot cat5e cable from my modem to router and don't have any speed degradation from it.

no see linus video about cable conections and check if the cable are in the right order or if the make good contact

Try using a different cable, may be damaged. CAT 5/5e/6 typically don't get signal degradation until ~100 metres.

[AMICLG]

Nope, as long as your under 90m your fine, and at that point you don't loose speed you just don't get a signal because the resistance of the wire after 90m is to great for the small amount of electricity going through it to reach the other side at properly.

Wow I thought for sure all the anime character names had been taken.

Actually he should be able to get about 100m without speed dropoffs (depending on the specific CAT# used, assuming Gigabit).

 

At worst, you'll start to see speed issues after 50-60m. Could be a bad ethernet cable, or environmental factors like excessive EMI, or other bad equipment (routers, NICs, etc).

[SlayerOfHellWyrm]

Nope, it's well within the max cable length, before you start seeing signal attenuation (loss)

What tools are you using to measure bandwidth?

I said, SpeedTest.net

Another thing to consider is the quality of the phone lines inside your house. The wiring to the new port might not be up to the necessary quality.

 

Length of the actual phone cable (Internally in the wall, or externally from the wall-jack to your DSL modem) should not be an issue. Generally speaking, a few extra feet here and there won't impact anything.

 

So you really need to try a new Ethernet Cable. If that solves your issues, then the other cable was bad. If it does not solve the issues, then your internal phone wiring may be bad.

Use iperf for internal speed testing

[spencermehta]

I completely forgot about this thread after solving the problem (sorry).

I tested the connection with another, shorter ethernet cable using another computer and the speed was still lower than expected. I restarted the router a few days later and the internet speed was back up at 60/20. No idea why that fixed it but it did.
