I have a cable modem and have been trying to get Mint to recognize the connection. I've cycled the modem, tried booting the machine with the cable plugged into it, tried setting the network connection to dhcp, tried the "Enable Networking" toggle to renew the lease. Nothing. However, this time when I clicked "Unlock" in the network settings and input my password when asked, the "Authenticate" button remained depressed for a moment, then the window gave itself a little shake and the password field cleared, followed by a little popup window that reads, "Could not authenticate" "An unexpected error has occurred." Rebooting the system didn't do anything and I'm not sure what went wrong. Any ideas?
