Read the manual. set SSID use WPA1/2 mode set in a wifi password, ( a good one, that is safe.) check out the new Netgear that have preset SSID. https://www.downloads.netgear.com/files/GDC/R6020/R6020_UM_EN.pdf I like where Netgear is going with that. pre assigned at the factory, and ready to run, no setup.. for noobs a big deal that. but your are not locked out of settings at all, PAGE 57

Have you registered this modem with your cable service? Press the Standby button to reconnect Internet service. Check the coaxial cable at the modem and wall outlet.
