I bought a cable modem off of eBay. I have contacted the seller.

When I turn it on it sounds like I am listening to a helicopter at low volume. Thumping noises.

I DDGed. It isn't electronic interference. It is on the same spot of my desk that my old cable modem was on.

I'm not sure I can open it or not, but the case has many holes. I may try running the hose attachment from my vacuum cleaner over it to try to get dust out.

Anything else I can try?
