I think I know the answer to this one but..........................

I think I know the answer to this one but..........................
Can you plug more than one Ethernet cable into a router, for 2 different computers without diluting the band width for either one?

  1. Good question. We have 2 computers both direct connect to our iinternet box BUT our computer guys brought out this small little box that is sorta like a router but different. How's that for a hazy answer. All I know is both Jim and I are connected, we have been on an HOA at the same time BUT we also take a bank loan out each month to pay for the speed we need ;-)

  2. The answer is yes and no. Any time you plug a new device into a router, you are sharing the same switching capabilities over more devices.

    However, practically speaking you are fine. A typical modern router is going to be Gigabit switching. That is 1000 MB/s. Your Internet connection is only capable of pushing 50 MB/s.

    Basically, that means that your routers local switching will ALWAYS out perform the actual Internet connection.

  3. This is not always so with WiFi. It might say 300 MB/s on the side of your router, but if you have 10 devices connected to your WiFi network, you will feel the sluggishness.

    I think the answer is: YES, there could be an issue. I think of it this way. 2 inputs, 1 output. Two 2 inch pipes as input, one 3 inch pipe out.

    The real question is: What is that 2nd computer doing?

    Leila, if you and Jim are both in a HOA, there COULD be an input. I suggest that you might not see the impact. If the second computer or third or four is streaming video, or in another HOA, again you MIGHT see some impact.

    Multiple devises using a set amount of bandwidth is what we are talking about. So, the issue is what is the bandwidth from the Router to your ISP. If your download speed is 10mb, you might and probably would be impacted with 2 devices, each with 10mb capability. But those same two devices connected to 100mb, again each with 100mb, you probably wouldn't see an impact.

    What is your upload and download speed from your ISP? That is the real question.

    When I am on an HOA, I try to turn off access to WiFi,  within my house, from other devices, iPad, Smart Phone, because those devices are also trying to get at that capacity to your ISP. They may not be actively doing anything, but there is some communications going on from those devices to the internet. You can control that.

    My issue is more the background stuff on my computer, like Dropbox, the cloud storage application. Those are what I turn OFF. That DOES impact the HOA.

    This is my experience. Don't know if it's right or wrong, but it's what I ahve seen.

    Our good friend Andrew Hatchett has given use links to ISP testing facilities in the community. Don't try just one, try a couple, as you may see different results.

    Hope that helps,

  5. We turn off wi-fi when on an HOA also +Russ Worthington. I will have to check up/down speed once I get going this a.m. Still on my first cup of coffee :-)

  6. A router connected via ethernet has far more bandwidth than Internet usage can overwhelm or even impinge upon. So, for hard-wired Internet connectivity, I would not worry about crowding the network. However, if you have only 5MB/s upload speed, the combination of uploads occurring will be added together toward that total maximum. The uploads will be on parallel channels into your provider through the router, though, so they will not directly interfere with each other. WiFi is an issue because the radio signal is distributed in a different manner than hard-wired ethernet is.

  7. Thanks everyone for your input. It was a great help. I tested upload and download speeds

    With 1 computer on Ethernet.
    The download speed was 34.12 and the upload speed 5.85

    With 2 computers on Ethernet:
    The download speed was 34.11 and the upload speed was 5.75.

    Thanks Russ Worthington  Terry Leigh Britton 
    Leila Martin Matthew Miller  for your help it is greatly appreiciated

  8. Be careful with those results. You are testing the Internet speeds from just one computer. You should run the test on both computers at the same time.

    Better yet, start a hangout on one computer, and then run the test on the other. Watch if the quality of the hangout degrades during the test.

  9. John Jurkiewicz - Matthew Miller made the comment that I was going to make. Start an HVC by yourself with yourself and then do the speed test on the other computer

  10. With one computer on a HOA the download speed is 34.11 and the upload speed 5.05

  11. John Jurkiewicz -- Interesting. Pretty close.
