Speedstream 5100b modem makes a high pitched noise |
|
|
| We just got the SBC Yahoo! DSL service which came with a Speedstream 5100b (5 light) modem. The only problem is the modem makes a continuous high pitched noise. It's just at the edge of my upper range and gets annoying at times. I wonder if this is a "feature" of the 5100b or (hopefully) just a problem with the specific unit we have? Thanks! |

The noise you are hearing is probably due to loose coil windings.
Spray some PCB lacquer on the coils and/or transformers in the
switchmode PSU section.

The modem itself? Or on the phone line? The latter is
normal and you need to install the DSL filters.
If on the modem, is it the modem or the wall-wart? Newer
lightweight wall warts are often switch-mode PSUs that can make
noise. Easiest to replace with a heavier transformer based unit.

Thanks for all the replies. The noise is not on the phone line (filters are installed). I'll have to check to see if the modem or the "wall-wart" is the source of the noise. The noise goes away when the modem is switched off, so it's definitely one or the other. Regardless of which it is though, shouldn't I just arrange for SBC to replace the unit? |

Yes, it would be best to complain. How else will
they have any chance of improving?

Folks might be interested to know that after a number of
phone calls to three different DSL divisions SBC is sending
out a new modem. I forgot how difficult and frustrating it
can be to get support from phone companies, but now I
remember <g>. I'll post again RE the noise after the new
modem is installed. |

Finally received the new modem and I'm happy to say that it
does not "whistle". Installing was a snap, i.e. after
connecting the wires I entered the setup and inputted the
user name and password - it immediately began working. |
