wireless speed problem /w pic?

distance between desktop and laptop ~3 meters in LoS

speed of the connection 54 mbps

yet filetransfer stuck at ~2 MB/s

Screen shot here:

any idea why?

i'd connect it using lan but i prefer wifi

Update:

thanks for your reply julie

sorry don't understand first paragraph? what do you mean that both are wireless?

i am transferring a folder from one pc to another - no internet connection involved

secondly

i do understand about bits and bytes etc,

it's just that the MAXIMUM speed for wifi 11g as far as i know is 54 mbps = 7 MB/s

the normal speed is usually a bit less because of overhead and interference

so probably more like 5-6 MB/s

what i am getting is only 2

compared to connecting using lan - mine is 100 mbps only

which is about 12.5 MB/s

i get about 11-12 MB/s throughput

not 5 MB/s

could the problem be that i am sending the data using Remote desktop connection?

    The only thing I can think of is that maybe the channel your wireless router is broadcasting on is crowded so it can only safely transfer at that speed or the memory or hard drive can't keep up with anything faster. That's all I can think of.

    First, you need to make sure that no other transfer is going on between any other computers in your home and that the other computer you are transferring from is wired. If it's also wireless, that would reduce your bandwidth by half, and your benchmark would be pretty good!

    If that's the case, then your wireless channel may be affected either by interference or neighboring routers' traffic.

    In any case, you should access your router's configuration and try different channels to find the best.

    It's important to note that the 54mbps maximum connection speed in no way corresponds to a file transfer at 54MB/s. One is in bits and the other in bytes. On a computer, there are 8 bits in a byte, but in most telecommunication protocols it gets closer to 10, and that doesn't count the TCP-IP protocol overhead which is around 10%, or the Windows file sharing protocol which also puts another 10% overhead.

    So you shouldn't expect to transfer files faster than around 4.3MB/s

    The 54Mb/s is the max speed on the wireless adapter you have. The 2MB/s is more like a normal speed. You can go to speedtest.net to check ur speed. Or contact your ISP to find your actual speed

    http://www.speakeasy.net/speedtest/ Go there and check your upload speed. I believe you can only go as fast as your upload speed.
