How fast should I expect to transfer files?

    Here's my setup:
    Cablemodem->WRT54GS->Laptop (XP) with 802.11g connecting at 54Mbps.
    ->Wired PC (XP) connected at 100Mbps full duplex
    I am using Sveasoft Alechemy, and WEP encryption, so I know there's a little overhead. But it takes about 30 seconds to copy a 4MB (MegaByte) file. To me that translates to about 1 megabit per second.

    I have searched the forum and one other guy says he can transfer a 1GB file in about 15 minutes. It would take me hours to transfer a 1GB file.

    What settings can I tweak to increase performance? And what software (freeware) do you recommend to monitor thorughput?

    Looks like I found the problem - sort of...

    Well, I tried a few tests to see where the problem lies.

    1) First, I connected my desktop and laptop with a cross over cable. I then copied a 4 MB file in less than 1.5 seconds.
    2) Then I connected my desktop and laptop with regular Cat5 cables, but this time going through the WRT54G switch ports. I then copied a 4MB file and it took about 30 seconds. Ah ha! I guess it doesn't have to do with wireless.

    After some digging around, I found that I had locked my desktop to 100Mbps/FullDuplex. I changed it to AutoNegotiate and Voila!, I can transfer at normal speeds again.

    Weird, though. Most people will recommend locking down the speed and duplex on all interfaces. I guess in my case, it worked against me.

    I re-locked the interface to 100Mbps/Full and it seems to still be working OK.
