What in the world are these TFTP errors in my log, please? Just had another (brief) outage and found them. Really worried as when I googled "tftp" there seems to be some indication of spoofing. ???
My setup is merely desktop, Vonage adapter and Arris WMB76a modem. No router other than the Vonage adapter. HELP !!!
