funny wireless internet with a *non* wireless modem

[steef <steefvanduin@zonnet.nl>]

hi folks,

i have a fast broadband connection, my provider is at home dot nl.

the connection worked like a charm till about two weeks ago, when the 
mailserver slowed down significantly, but the browser kept working as 
fast as ever.

my provider could not tell me the cause of all this so i decided to do 
something myself. I installed (under etch) an asus wireless card with 
the rt2500 module, which works fine since yesterday-evening:.... sends 
my emails as fast as my onboard chip in the old days.

the clou: so when i send emails from my two maillists with the  onboard 
nvidia-chip the process is slow as a snail.
when i use the wireless chip of the asus-card it goes as fast as ever.

i have *not* a wireless modem and yet the rt2500 chip of the wireless 
asus-card does its work very well.

somebody out there who understands this??

some explanantion will be highly appreciated,

regards,

steef
