Christian,

There is no reason to apologize, you and Willibald have done a
fantastic effort getting us to this point!  There's always a few
growing pains to wade through as you will see below.

Believe it or not, my Window box refuses to connect with anything! 
Rather than mess up my working Actiontec DSL system with WEP wifi, I
uncrated from storage a Linksys WRT54g I had when I was contemplating
using a cable setup.  (When I decided to go to DSL, I needed a new box
since Qwest use PPPoA and the Linksys only support PPPoE).  The Linksys
box has a WPA option to use TKIP (WPA) or AES (WPA2).  When I tried the
AES option I had the same problems I had with the Actiontec box. 
However, with TKIP enabled and changing the the XWLAN option from WPA2
to WPA, I was able to connect and had a working network!  All of leads
me to believe that we have the usual "standards" problem!

No, the red bars were for WPA2.  There is minimal documentation, but my
understanding is that the Actiontec gateway I was initially using only
uses AES for its WPA-PSK operation.  There is no option available to
switch between TKIP and AES.

Will do once I do a little further investigation.  I need to disable
Object Desktop, possibly Norman AV, C-A-D Commander ... to narrow
things down.  BTW, there were no problems with Genmac 1+.

I am using fixed IPs only and I do use the radio on/off technique. 
This is not a big problem since the script technique is working well.

Thats, ok.  I have found that NetBIOS over TCPIP can be very finicky
about configuration and caches being properly cleared.  I once tried to
clone two machines from a backup file and change the network settings
(IP, name, etc) for the second machine.  TCPBEIU complained for quite
awhile that I had two systems with the same name on the network!  It
took a painstaking clearing of the caches of ALL the computers to clear
that up. 

Cheers,

Chis
