I have an AT&T DSL modem that they sent to me. SPEEDSTREAM 5100 ethernet ADSL modem.
It emits a high pitch squealing noise. It's barely audible, but it's unpleasant. Can anybody guess what that sound might be and tell me if there is something that can be done to stop it.
I seriously don't want to use it, so I do not at all mind risking its destruction. Soldering is no problem here. Or maybe somebody knows of an effective physical shielding from the noise.
I can ask AT&T, but... Nowadays, can you just go to the store and pick up a new similar modem to use with AT&T DSL Internet service?
Thanks.
