What could cause a smc8014wn modem to hum quite loudly (sounds like a vibrator)? Only lasts for 1.5 seconds. It's happened 4 times now in the last week. Seems to be working fine otherwise.
Power supply would be my first thought, but I don't remember if the SMC has a separate power supply (brick somewhere before the modem), or if it is built in
It's separate. Can't imagine why that would hum. Not sure how I could make sure which one I'm hearing. Will have to think of something.
Intermittent or constant humming is a sign of a bad power supply (the hum is usually at 60 Hz),
That is why it is my first thought
Just checking in here, were you able to resole the case of the mysterious humming?
Thanks for the interest. Unfortunately (or not) it hasn't happened since that email. I'm assuming that it's the power block. I don't imagine that there are any moving parts in the router/modem. If it happens again, I'll just get a new transformer.
Thanks for letting us know. Hopefully it doesn't reoccur but let us know if it does.
Have a great weekend!
