    Is there an average speed that you should reach on a 100Mbps connection?
    This Bandwidth Unit Calculator states that 100Mbps connections should yeild 12.5MB/s, however I've not been able to top 9.5MB/s using a crossover cable...

    Also, I've only been able to get 800KB/s through my router, at 10MB half, whereas 100MB half yeilds about 30KB/s. Could this be the major difference between integrated controllers, as one is a ASUStek/Broadcom 440x 10/100 and the other is a Marvell Yukon 88E8001/8003/8010 PCI Gigabit Ethernet Controller. Or does LinkSys just suck that bad?

    It should be going higher than 30KB/s throuhg a router...

    With my computers they all have different brand network cards (2 are integrated, 1 is a PCI card) and I can copy a 700mb file in about 4 mins from my computer ot the next fastest.

    How would I check the actual mbps tho.

    BWMeter, measures LAN speed as well as all other bandwidth activity.

    I tried moving a 700MB file to another PC at 100Mbit half through my router, and it estimated that it was gonna take 192 Minutes. 27 minutes at 10Mbit half. However with the crossover cable it took about 45 seconds, but it's a pain in the ass to change the crossover to strait through and visa versa all the time.

    12.5 MBps is the theoretical max of your network hardware
    I think you have to allow for overhead and such
    9.5 MBps don't seem that bad
    maybe you have to consider other factors as well
    hard drives, mobos, etc.
    ermmm......lynx? clocker? VB? anyone?

    and you don't need that bandwidth calculator
    8 bits (b) = 1 byte (B)
    all you have to do is divide Mbps by 8 and you get MBps
    you do know that Windows (and probably evey other OS on the planet for that matter) has a calculator?

    I wasn't sure the exact number to divide by, so I just searched for something that would...

    Yeah I agree 9.5MB/s is pretty decent speed, however I was just curious as to why the other 3MB/s weren't registrering.

    I suppose my main concern is why I can't get decent speed through my router. No matter which speed or duplex I set it too, I'm still unable to obtain anything over 800-850KB/s, whereas Linksys routers boast 100mbps speed for wired networks. So I would assume that I would be able to get the same speed through the router as with the crossover...
