Leo 10.5.2
Using Viarhine.kext
Dlink DFE-530tx (picked it up at office depot for $5)

Slow uploads (90% slower than normal)

Someone with a MacBookAir said they have the same problem only after install the 10.5.2 update http://forums.macrumors.com/showthread.php?t=435717

Anyone else have this issue?

Can anyone suggest a better driver?
