Lets try a couple of things and see if it helps.
discconecrt any usb modules or teathers...use only your wired solid connection.
please open a terminal ctrl/alt/t then COPY and paste one line at a time..
Code:
sudo apt-get update
echo "blacklist ideapad-laptop" | sudo tee -a blacklist.conf
sudo apt-get remove --purge bcmwl-kernel-source
sudo apt-get install --reinstall bcmwl-kernel-source
sudo modprobe wl
next please access your router settings and remove the TKIP setting
and relpace it with WPA2 AES.
reboot and test wireless.
thanks.
Have run the commands, the connection is currently working.
I will reply later in a few hours if the connection is working without problems or not (more testing)

The W-Lan settings of my router has been not changed, I have no access to them (only my parents)

Thanks for your help
