[maemo-developers] [maemo-developers] Unreliable Large Network Transfers

I don't have any advice for you...but I do want to say proprietary
wireless drivers suck, and this is a very real example of why. Shame on
Conexant for not working with the Prism54 guys, and shame on Nokia for
using proprietary drivers. It sounds like the driver needs fixed, and no
one can do that except for Conexant or Nokia.
