since yesterday, my light on black bnb box is flashing.
to be specific, top first is solid on. second one (downstream) is flashing, third and fourth( upstream and online) is off overnight. because of that, internet light on my white modem is off too.
it's been 1 day, and it has been quite often. just 2~3 weeks time, it happens. sometimes it fixes itself overnight. but sometimes it doesn't.
what do i have to do? i can call technician, but wish to fix it on my own and figure out the problem.
Thanks tech experts.
