View Full Version : Can wireless-SB2 transmitter be powered completely down?

Just wondering. Let's assume, just for argument, that someone -- say,
me -- is an obsessive freak who tries to optimize whatever can be
optimized with respect to the ol' stereo. With the SB1, I encountered
occasional hiccups when streaming uncompressed 44.1K PCM which
disappeared when I hard-wired it to the network. Given the bigger
buffer and 802.11g capability of the SB2, this may cease to be an issue,
but I still might end up sticking with wires even if I get a shiny new
SB2. If I get a wireless SB2 and end up deploying it hardwired, can it
be configured (either in software setup, or even by pulling something
internally) to keep its wireless circuitry powered down, on the off
chance that that might inject detectable RF noise into nearby audio
componentry? If so, there's no disadvantage but price to buying the
more-versatile wireless SB2; otherwise it's a less obvious decision. At
least, for the previously-stipulated unidentified obsessive freak.

When a wireless Squeezebox (1 or 2) is configured for Ethernet, the
wireless card is held in hardware reset, and is not initialized at all.
I don't know to what extent the wireless chipset electrically powers
itself down internally, but I'm certain that the radio is inactive and
it is neither transmitting nor receiving packets.

I'd assume that it is "as powered down as possible" because these
chipsets are made for laptops and PDAs where battery life is critical.

You could also just take the wireless card out and save if for
when you might need it; if you don't need it that is.
