Using Surfboard S33v2 on Optimum network for less than a year. The normal state showed a blue LED. We then had an outage that lasted a couple of hours. When service came back, the LED started orange, then flashed green, then went off - no solid blue. However, the unit seems to be working normally. Why would the Blue LED no longer appear? I **** getting 800M download speed. Does it need a software update?
