Hi Carolpa, Hi rxcohen,
Thanks for your replies.
Today I could solve the problem and connect my BS5 Encore to the internet via my Fritz!Box.
I had to reset my BS5 Encore to factory settings in order to make it "forget" the WLAN settings. Then, I was able to connect as expected. E.g. via the "Wireless Auto" setup.
In order to reset the BS5 Encore one has to enter a hidden service menu by doing the following:
- Go to 'mode' -> 'settings', but don't press <go>
- Now press <arrow right> two times and then <go>. This opens the service menu in English.
Now, I looked for the option to "reset to factory defaults" under the "Maintenance" menu and pressed <go> to reset the BS5 Encore.
Then, after starting up, I was able to connect to my 5 GHz WLAN and could also make use of the media server that is offered via my Fritz!Box.
Everything works fine now
