I have an issue with my sonicwall tz series. I've completed wizard setup and upgrade with the latest firemware. Somehow after the setup, I don't have an internet connection.
1. I've checked the connection x0(lan) and x1(wan) and when I log into the sonicwall from the login page, I can see that x0 and x1 have signal with 100Mb connection.
when I want to register my sonicwall from one of the link, I got the 'Connection failure' error. It says that 'DNS lookup failed, please check your DNS server settings'.
I am using a cable modem and during the initial setup guided by the wizard, I choose the cable/modem configuration.
Is there something that I've not configured correctly? Thanks
