Recently I received that new Xfinity modem (XB3), which looks pretty much like my previouis modem, but larger. I set up the modem in Bridge mode, meaning that it works as just a modem and nothing else. My personal Netgear router handles everything else including WiFi. When I switched the modem to Bridge mode, it's built-in WiFi went off, as it should.
Since then everything has been working as expected.
However, the 2.4 GHz and 5 GHz lights on the front of the modem keep blinking all the time. This is annoying. I don't use modem's WiFi and I'd prefer these lights to stray permanently off. How can do that? The previous modem also had built-in WiFi and was also used in Bridge mode. And its WiFi light stayed off. Is there any way to achieve the same with this new modem?
