with driver v4.0q I got:

AP->laptop  3.0Mb/s

laptop->AP  2.7Mb/s

anyway I noticed that enabling/disabling mode4x did not affect
performance from laptop to AP at all...is that ok IYO?
what are performances you get typically?
Finally what does it mean a timing/compatibility issue?
I have a USR805410 pcmcia card and a USR808054 AP and they are both
100Mbps products...

thanks again,
for your kindness,
Cristiano
