Ethernet speed VERY slow

[JAC]

Hi Mark,

I have a 1gbps powerline adapter that I usually use with the laptop upstairs (as I previously didn’t get good speeds) I have great speeds to the Virgin hub, but very poor speeds when ethernet is connected, and without the VPN too!

With ethernet disabled and wifi enabled I get much greater speeds, just like I am now seeing on the Nvidia Shield box.

Is it time to ditch these?

I have the new hub 4 with 1gbps speeds to the box and 1 wifi pod which appears to be helping massively.

Speed upstairs to the laptop via wifi is…

… which I’m very happy with, I know it varies from device to device but considering I was once getting only 19mbps up here in the top room I’m very happy with the results, but slightly concerned as to why speeds are so slow via ethernet.

@JAC is the speed consistent across these devices completed to your phone in the same location ? What speeds do you get from the laptop on wireless and on wired ?

Speeds can vary as we know. So I’m currently getting around 350mbps to the mobile phone, something which is probably at its limit so I can’t complain with that.

It appeared to be on the laptop in the top room where I had the issues, and was getting sometimes 13mbps through wireless and even less with ethernet plugged in.

I have just got the second wifi pod through the door so I’ll test it when I can mate to see if it’s any better .

@JAC wired connections should always be faster than wifi, but there are some variations to this. Are you sure that the Power line adapters you are using are in fact 1gbps ? From recollection, they aren’t, but I could well be wrong here.

These are the ones I purchased a few months back mate.

@JAC ok, good. Can you try the following with the network connection (not wifi)

1. Click Start -> Settings to open Windows Settings. Click Network & Internet.
2. Click Status in the left panel.
3. In the right window, click View your network properties link under Change your network settings.
4. Under Properties, find the network adapter, the Ethernet or Wi-Fi, and find the speed next to Link speed (Receive/Transmit).

Send a screenshot of what you see. It would look something like this

Thanks for the reply Mark, I did this earlier and it was 1000mbps / 1000mbps.

@JAC ok, so not an issue with the port speed or duplex settings. Have you tried updating the device driver to see if that makes a difference ? Also, a long shot, but could be caused by antivirus software.

You can test this by disabling the antivirus temporarily to see if that makes any difference to the speed (although honestly, if this were the case, I’d expect similar degradation on the wifi adapter also)

Thanks very much for the reply mate.
I’ll try what you have suggested and report back.

[phenomlab]

@JAC thanks. Definitely interested in the results

Yet to try this but a good test too would be to use the Power line adapter that allows 100mbps max through it and see if that yields any different results.

[phenomlab]

@JAC Well, no, not really. If you do that, you’ll never get above 100Mbps on a 1Gbps line as they are capped at 100Mbps

Absolutely mate, I know what you’re saying, I was purely going to test to see if it came out above the 12/13mbps I reported on Sunday.

I’m just looking to test that to see if it’s the 1Gb power line adapter that is the issue, which I’ll do in the next hour .

If you have gigabit hub you should only connect all gigabit connections to stay gigabit mode, in case if you connect a 10mb connection the hub will siwtch to 10mbps mode instead of 1000

In some cases you should bind ports on router to convert all ports into gigabit

I’m not sure about you found solution or not. I make sure these things when i deal with gigabit eth cables.

This isn’t true. Hubs are pretty much dead for network connections these days with switches being preferred. The technology difference between hubs and switches is vast in the sense that if a Hub (for example) is 100Mbps and has 24 ports, 100Mbps is shared amongst those ports.

With a switch, if you have 100Mbps and 24 ports, each port in fact gets 100Mbps - the total bandwidth available is known as the “backplane throughput” - provided the total backplane exceeds the port x speed equation. So, if you wanted a guaranteed 1Gbps throughput on each port with 24 in total, you’d need a 24Gb backplane

As an example, the switches we use at work (Cisco Catalyst 3850 48 port POE) have a 176Gb backplane (they are business / data center usage, so no surprises there). The “consumer” switches (such as NetGear for example) will have nowhere near this, and therefore, the overall speed of the port will be impacted by the amount of devices you have running simultaneously.

Thanks for the update. I have just connected via the other powerline adapter and the reading shows 34.7mbps.

@JAC Yes, totally expected. It’s capped at 100Mbps.

wifi giving greater speeds to the laptop now.

The reason for the ethernet cable in the first place was because the wifi kept dropping out on the laptop.

Seems ok now mind

After saying that, I’ve just done a speed test and it shows pretty low compared with last weeks reading…

how can it be so inconsistent

A reading from my phone in the same spot…

Although the readings were greater last weekend, is this a case of range and the fact other users could be on the internet too?

I use this in the top room but whatever I’m getting now is still an improvement on what I used to get up here . Sent off for second pod.

Tried in kitchen earlier where we have a pod plugged in in the hallway so not far from the kitchen, I was getting over 250mbps last week but it was around 130 this morning, something’s not right .
