    I'm wondering how fast the average wireless network should be, when transferring data between two of the networked computers (one wired one wireless)

    it seems that mine is very slow, so slow i prefer external hard drives and flash media than just transferring over the network.

    can anyone give me an idea of how many kbps a wireless network should offer?

    i guess use the example of sending a 700mb divx file. should it be between 400-900 kbps? or more like 50-100? it looks like my network takes 7 minutes for a 700mb divx file, is that normal or slow? hdd to hdd takes about 2 minutes

    also, the wireless computer can download at 1.2mbps from the web

    700MBytes = 700 * 8 = 5600 Mbits
    7 min = 7 * 60 = 420 sec
    5600 MBits / 420 sec = 13.33 Mbit / sec

    This is normal speed for 11g connection. The advertised 54 MBit / sec for 11g connection has been never achieved. The reality was at most half of the advertised speed. Higher speeds possible with next generation adapters and routers.

    hmm thats too bad. why does my external hard drive transfer data so much faster though? and how much faster would using an actual ethernet cable be?

    External hard drives on USB do 25-30 MBytes / sec = 240 MBits /sec (again much less than the advertised USB speed of 480 MBit/sec). So you get about 20x the speed of wireless.

    If you use Firewire, you will get up to 40 MBytes /sec, and on ESATA - up to the drive speed, i.e. with a new drive up to 80-90 MBytes / sec.

    On Fast Ethernet you get about 12 MBytes /sec ~ 100 MBit /sec.
    On Gigabit Ethernet connection - depends on the drive and the CPU of both computers - up to 800-900 Mbit / sec.

    wow thank you for that data, you have no idea how much that cleared up for me.

    im going to be getting a new dir-655 router with gigabit ethernet, i would just need a standard rj45 cable for it?

    and whats the chance my laptop and desktop are both compatible with gigabit Ethernet =p

    ive got an asus g1s notebook and a pretty old custom pc with a asus a7n8x deluxe mobo. is gigabit Ethernet a very new thing?

    Cat5e or higher cables

    Most PCs purchased within the past couple of years are all coming with onboard 10/100/1000 NICs. Doing a quick Google of your laptop and your motherboard confirms they both have onboard 1000 NICs.

    ahh yeah thank you, im actually surprised, my laptop and desktop both have gigabit ethernet, w00t!!!

    also something i just found out...my notebook is capable of 802.11n Wireless LAN


    does that mean i can/should i use wireless n technology with my new dir-655 router?

    Instead of what, a wired connection? Wired is always preferable over wireless for speed and reliability.

    Go ahead and try both and see if you can tell a difference or have a preference.

    wireless n is sooo nice. I'm getting the same speeds in a speedtest that im getting on my desktop computer (wired), and data transfer between two computers in a network is almost as fast as true ethernet (wired)

    I'm luvin n
