I am connected and have an IP address, but I cannot establish a connection with any Internet server. I have the impression it is related to thee DNS lookup, which waits forever for a result. Cycling the connection (disconnect->reconnect) seems to fix the problem for some time. I am reporting this against network-manager, but I am not sure if it is directly in network manager or if it is systemd related. With 14.10 everything worked perfectly.
