I just want to say despite many nay-sayers posting responses to this on other threads there is something in my SB 6141 that vibrates with uploads. (correlated by noise during speed test).
These two links are have the identical report and then other people trying to argue that it’s not the cable modem. It is the cable modem! It happens with my the use of my phone over wifi, with my computer, laptop, with all the screens and speakers turned off, there are no headphones involved.
I can modulate the sound during an upload by twisting the case. Viewed from from the top of the case, if I twist the top clockwise and the base counter clockwise I can decrease and eliminate the sound.
Really annoying to have a fanless, ssd desktop and a noisy cable modem.
