    Okay, so I've been having a heated discussion with two people who think that on a LAN a wired connection has priority over wireless connections. I was telling them that sure, there may be issues with the wireless that would slow down the connection between the wireless client and the router such as microwaves, walls, whatever... but when the wireless is 54Mb and our internet is a 1.5Mb DSL connection, you aren't going to notice a speed diff unless you have QoS turned on. We're using a wireless-n linksys router. They were saying that because "electricity" takes the path of least resistance, the wired connection will be faster.

    their explination is wrong, but their statement that wired is faster is correct.

    a wired connection should net a much lower latency than wireless. Packetloss should also be much reduced with a wired connect compared to wireless.

    But on a 1.5Mb connection, you are not going to have a slower speed on the wireless vs the wired. Again, on a LAN connection, yes you will see a diff but on an internet connection that low, you won't.

    I disagree.

    I have first-hand witnessed this difference on many occassions with many different broadband connections. Wired is simply more responsive than wireless.

    Are you measuring speed based on downloads? If you were to download a file on a 1.5mb/s connection with wired and wireless, you probably would not notice a speed difference. But with overall performance, there will be a difference in performance with wireless. A simple test would be to ping your default gateway or another machine on your network with the wired and then with the wireless. You'll see the difference.

    +1

    Pinging my gateway (I'm currently wireless, around 5 feet from my router) I get a ping time of 2-4 ms, while when I connected directly, it was always <1 ms. But like EvanD said, downloading from a website, you won't see any difference whatsoever in response/download times between wired and wireless.

    The speed via wireless isn't going to be slower than wired if the outside network is slower than either of the local connections, but wireless still has higher latency because it has to constantly ping the receiver to make sure it's still connected before it sends a packet, whereas a wired network connection can just measure the electrical continuity of the cable (which doesn't take any time at all).

    it does take time. And that's why there's still latency on wired networks.

    for all the speculation in here has anyone tested either side of this?

    wired, run 10 speedtests
    wireless, run 10 speedtests

    which (on average) is faster?

    /question

    (btw, on average, wired is going to be slightly faster)

    When my roomate and I play CS:S on the same server his ping is always 1-2ms higher than mine. He is on wireless and I am wired. Not a big difference but the difference is still there. :dunno:

    i agree. a wired connection downloading an iso compared to a wireless connection (b or g doesn't matter) will download the iso quicker. i see about a 10kbps difference

    just think about it. the signal has to be transformed into rf, latency and packet loss can occur, then it has to be decoded etc. there is more overhead with wireless. also, i read that there is about a 3% performance hit when you use any encryption
