[MLB-WIRELESS] Transfer Rates

Cameron,

transfer rates are a little tricky, 'coz there are two ways of 
measureing them

1    PURE Bandwidth - how many BITS per second!
2.   Transfer performance (usually measured in BYTES per second)

The stats you are getting are pretty reasonable, but you should be able 
to get about 550(-600)k/sec


these cards are 11 Mbit,

if you work it out, you are getting about 2.5mbit transfer rate (not 
counting TCP overheads) Bear in mind that these devices are 11mbit TOTAL 
bandwidth, so if you have two PC's communicating, then you can really 
only expect up to approx 5Mbit transfer, 3PC's then about 3.5 Mbit & so on.

Wireless is NOT switched bandwidth like most modern wired networks, but 
shared (like running a hub instead of a full switch)
 Personally not sure about what effect using an AP is having, but this 
*could* be reasonable!

maybe the rest of the list can help you more....

well done on getting your WLan up & running!
