Hello HerrBert,
thank you very much for your answer. It is really frustrating. Since my last reply most time with just "local access" (Zugriff nur lokal)... Wrote this message when it exceptionally worked, pressed the "send" button and ... I am a very patient person but ... that is to much.
Last try this night: I turned the firewall off and tried it again. The same result as before. Can´t connect to the internet. Normally when I connect my Laptop wireless to a router "directly" I do it with the firewall on, and in this case the renter of the flat get the connection from my laptop via his Fritzbox channel ("directly" - Heimnetzwerk) with the firewall on, so I don´t think that it is the firewall that causes the problem.
The renter also showed me what options his Fritzbox has for the guest account: 1. WPA2 (CCMP) and 2. WPA2 + WPA3. We tried both, but it made no difference. There are no other options. So what could it be?
And why does it work with vista???! Don´t wanna buy a Windows laptop
