Using the Cloned MAC Address feature in Network Manager (with a generic MAC address), the connection failed to establish for a public wireless network with no security in Ubuntu Natty 11.04 on my Dell Inspiron R14.
I tried the same thing on a hp EliteBook 6930p with Ubuntu Maverick 10.10 (not up to date) and it worked.
