That is that I am connected (whether through WiFi or ethernet cable) to a university network which claims after the upgrade that the laptop is no longer registered. I went through the registration process again through the browser (and was told: why are you registering this machine again, it is registered, simply restart the network/reboot) but the problem does not go away. I upgraded a desktop on the same ethernet switch and this problem did not go show up there (I am using that to write this email).

Ignore the browser for the moment. Go into Network Connections and see 
if your install is cloning a random MAC address. I *suspect* that the 
registration "feature" may be checking against the MAC address, while 
the browser passes through the SSID + password only. Just a guess but I 
have had the same problem with my android cellphone getting a 
DHCP-served address instead of the expected static IP due to a random 
MAC address.
