Yesterday my SBG6580-2 receive light started blinking and wifi stopped working. I have tried power cycling and the hard reset button on the machine. Looking at different trouble shooting didn't help since there wasn't a case written out with the same light combination. What are the next steps I should pursue? When do I say this machine is broken and get another one?
