Hi Isaac,

   You know you have to unlock the files before you can load different versions "over" the files don't you ? Otherwise you could end up with the v 1.6 helper exe and version 2.0 of the driver (the helper exe didn't change between v 1.6 and 1.7 I think).

Cheers/2

Well, I'm not so concerned about the actual numbers. But they do seem
to correlate with perceived performance. Even when I do have
connection, it seems noticeably slower than with 1.6 no matter where
or when I'm surfing the web.

I could kind of live with that, but not with it crapping out or
failing to acquire.

This particular laptop just had a fresh (2 weeks old!) install on
which I put on a clean GenMAC 1.6 install. I then installed right over
with 2.0 a few days ago and saw the same problems as I did with 1.7 on
a previous installation. I installed right over again with 1.6 and it
is very happy now.....mysterious....

I had no problems connecting to either of my AP's (home and work) with
any 1.x.  It did seem to take quite a while to acquire an IP but I
couldn't say it was out of the norm as it has been so long since I
connected windows via wireless I don't recall how long it took.  2.0
seems to take about as long via a WEP connection but WPA seems to get
an IP much faster (there are some variables I need check before I can
say that definitively).
I have noticed that with genmac 2.0 (whether with wlan 2.14 or 3.0) it
does show to have a weaker signal.  What I have not determined as yet
is whether the signal is actually weaker or if the guage is more
sensitive/accurate.  I have also seen stronger signal than I have ever
gotten as well - such as right now I am seeing 100% which the
strongest I had ever seen from this AP is 88% and my T42 is/has been
literally 3ft directly above the AP.  I have been watching the signal
strenght and it has dropped to 86% (which is what it used to mostly
sit at) but has mostly been 90 - 100%.  I don't know why it has so
much variance which it used to not have but with the range involved
90+% seems more reasonable than 86-88% but the more constant numbers
seem more plausible so that one is a hard call.
