    Ethernet slow


    Hi guys, having very slow download speeds through powerline adapter. I get about 16.20 down 7.70 up ping 35.75, this is on my desktop pc, if I connect my laptop to the same powerline adapter, i get about 32.70 download etc. I have tried the tcp optimiser with no success. Any help would be appreciated. Thanks.

    Good morning and welcome to the group. If you are talking Mbps speeds, I would be thrilled with that performance.

    Slow ethernet.


    Thanks for your reply. As I stated I should be getting around 32 mbps as the laptop does. ( on fibre ). I should have also mentioned that this is on a speed test not downloading a file.

    Can't find my clip to insert, but mine are 5.7 mbps up and 0.47 down. Small town life does have it's drawbacks.

    ethernet speed


    That's similar to mine for a file download 5.3 at best, but not tried downloading a file to my laptop .

    ISP tells me the 6 Mb service I have is the fastest available at my location. If nothing else, I have to say it's been reliable and trouble free.

    Hi keesu.

    I assume we are talking wired connection as you labelled problem Ethernet, if my assumption is wrong let me know.

    Open up device manager and then the properties to your NIC. Check link speed and whether you are using full or half duplex. I would think you want "Full". You likely have an Intel NIC so there should be a tab in properties. For Realtek you find speed and duplex under the Advance tab. You may also be able to compare overall setting with laptop.

    First, I would double check that the situation is what you think it is. When you say you hook up your laptop, are you certain it's not using your WiFi to perform the test? Just plugging in an Ethernet cable does not mean it will automatically use the Ethernet in many cases.

    Many power line adapters can only do 200Mbit/s, which is a theoretical max of 20MB/s, but in reality will be significantly less. The newest adapters that support theoretical speeds up to 2Gb/s, but again, in reality it's much less, and often depends on the quality of your wiring, the type of junction box you have, and the distance of the wiring it travels through. For instance, in this article it states that they were getting speeds of 279Mb/s at 10m and it dropped to 74.6Mb/s at 25m.

    Also, be wary of the difference between Mb/s and MB/s. Most speed tests measure in MB/s, which is usually about 10x lower number than the actual Mb/s (there are 8 bits in a byte, but there is overhead which makes it come out to about 10bits of bandwidth to 8 bits of data as a rough estimate). So 50Mb/s is roughly 5MB/s.

    Thanks for your reply Mystere. It is ethernet connection not WiFi as I switched the WiFi off, it shows in the system tray icon if you are using WiFi. Also WiFi is much slower on the laptop.
