    Ok... I know, I am a math wiz! :)

    I was doing some network speed testing. I can transfer a file from my Laptop through my Linksys 54G router to my desktop at a rate of 2.6 MB/s max. Why can't I hit the theoretical max of 6.4? Is the 2.6 cut in half to account for both PC's? I have tweaked the setting best I can too at

    Tweaks

    Thoughts?

    That's assuming they both have 100% signal. I get what 1 MB/s but usually 600-800 KB/s max :/

    Why? The desktop has a not so great linksys USB dongle for its wireless. It probably grabs the thing at what 60% tops? And my Dell Vostro with its G wireless card gets about 75% from right upstairs. Interference and whatnot probably is dropping the rest down.

    Remember, in the world of advertised numbers, it's always "near."

    Don't use those tweaks, they're in the grey area of voodoo and guesswork.

    There are two things here.

    1 - I did some some tweaks and I was able to 2x-3x my download speed from the internet using a service like http://www.speedtest.net. So the tweaks do work.
    2 - The speed of 2.5 MB/s is what I get going from my laptop to the desktop through the router. My question is... should I get 6.4 MB/s? Or is 2.5MB/s the best I can get?

    You don't get over 2.5-2.6MB/s on a G network- 54Mb/s is a theoretical throughput while actual data is no more than 50% of it.
    You can change the router, the card or stand near the router and you won’t get any higher (unless you use some SpeedBooster/Afterburner technology)

    Another words- if you transfer a lot of data via wireless you might wanna give draft N a chance because you won't get anything more from G standard.

    If you transfer a lot of data, get an ethernet cable... ;)

    54mbps is the theoretical max on 11g, just like 300mbps is theoretical max on 11n, 11n will do around 80-100mbps (8-10MB/s), so it makes sense that 11g does around 20-25mbps (2.0-2.5MB/s) :)
