so, reasonably healthy again
first:
as hawhill said: the scatter error didn't affect the wifi connection.
Got the same Message by using it in a working homenetwork.
second:
the Message: ' not connected' in the Wlan-Settings is 'Amazon-style':
if the kindle is connected to wlan but not to internet its 'not connected'
third:
the testnetwork is set up by a Cisco Air-Cap2602 and with full access to all
router settings, so the Problem is definitive not caused by restricted settings.
with the cisco router I can connect the kindle in a 192.168.2.x /24 with no internet-access (testnetwork),
but if I change the addressrange to a larger area, using IP 172.11.16.28 with subnetmask: 255.255.248.0
than i get a 'Wlan-Error' Message Window by conneting.
BUT
as long as i stay in this Error-Window the Kindle is connected with the network
and it is possible to use - I am running a VNC-viewer by now
So problem solved, work done but still feeling like a monkey on a anthill *don't know why, but it works...*
*the last pic is the verification, that vnc-connection is still online, when I remove the USBnetwork, which I used to control the Kindle
