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.
