With stepwise guidance from Verizon Customer Support, I changed the Verizon-supplied router from WEP to WPA2. System Preferences on MacBook Air (OS 10.7.5) shows "none"for the network's security. Rebooting the machine and logging in and out of the network don't make a difference. Verizon has confirmed remotely that WPA2 is indeed in place. Why won't my machine report that correctly?
