Hi Volker and welcome to the WTT forums, Sorry to hear about the wi-fi issue on your home network.
Its is good that your Internet works correctly when connected wirelessly on a different (unsecured) network but not on your home network.
I think the first thing to do is to:
1 power cycle your modem /router and then close down your computer, and restart it after 2 minutes.... see if there is any connection
2 If there is still no connection then enter the router/Wireless Access Point set up page and remove on a temporary basis the encryption that is being used (WPA2 ,WPA, WEP etc ) so the wif-fi is not secured... Try a short test...do you now have a good Internet connection?
Post back with exact make and model number of your Acer, your modem/router/wireless Access Point... if you need more detailed instructions on a particular part of any of these suggestions.
