What does the second light on my NBN modem mean? Since last night it's been flashing red and making a clicking sound. I've turned it on and off again and left it off for hours overnight and now it's been turned on again for over an hour this morning and still not working. According to nbn website there's no outage in my area and the other modem is still working (the non-nbn one). On my laptop it's still connecting to my internet name and says it has full bars but when you go to load a page it says no connection.
