Internet connection was lost after a recent program download that some had flagged with suspcious nature. A static IP address had been established through a Netgear (WNDR3300) router with an antiquated Netopia modem. Static address/Defaut gateway has always began as: 192.168..... After connection loss, reset (or so I think) IPv4 properties back to: Obtain IP address automatically and have received an IP address as: 169.254.172.83. Also have not been able to access router or modem settings/configurations page(s). Thanks for any advice or instructions available.
