WIFI NDAS disk speed check

Hi,

New to the forum and to Macs, I would like your suggestions and ideas on a particular issue in which I am a little bit lost. Sorry for the English as well, not a native speaker.

I have a multimedia player, a Rapsody N35, which works as a NDAS disk, connected to a wifi router downstairs. I can mount and read/write the N35 disk from my iMac upstairs and even stream contents from it. However, the speed at which the files are copied to the disk via wifi seems to me a little too slow. It takes approximately 6-7 minutes to copy a 700Mb Divx movie.

The question is that I have been having problems with the configuration of the ADSL and wifi routers, and I do not know if this speed is what I should expect as a limitation of the wifi transmission ("g" standards) or there might be a firewall issue and I should expect something faster. Is there an easy way to test the real transfer speed of the communications imac/N35? and to guess if they are as good as they can?. Would there be some way to make the communication faster withoug wiring?. Thanks in advance

 

Thank you. Apparently there is not problem in the wi-fi connection and definitively I don't know how to adjust the packet size output, if at all possible. The NDAS driver does not seem to allow any kind of adjustment.
