View Full Version : Microwave inference minimized (finally)

Well, I finally took the leap and separated my networks. One wireless
network just for my music, which consists of 2 SB and one Slimp3 and
the server. When I separated the networks, I put my music on channel
1, and the rest on channel 7, my neighbor uses channel 11. Channel 1
seems to be the magic number with my microwave, maybe other channels
would do better with other channels.

Since the change, I can use the microwave (knock wood) anytime and
there is no music interruption, whereas when the music was on a
different channel all I had to do was put the microwave on full power
for 15-30 seconds and the music stopped, and about 1 minute or so on
defrost would stop it (30 seconds on defrost was no problem).

I thought there was no hope for microwave inference, but now, well, it
just works.

Now to see if I can use a 5.4 GHZ phone (not too many 900 MHz phones
left anywhere).

Thought others might benefit from this,

Who would have ever thought that wireless network debugging
would include a reference to one's microwave settings?

What happens when you set it on 'Popcorn'?

Why kraftwerk? I would have though Jean-Michael Jarre more appropriate:)

Speaking of wireless interference, though, I just made my daily 45
minute bus commute with my battery-powered SB and my notebook as AP on
channel 1. This is my 2nd trip with that setup. The first time,
friday night, I had no dropouts, but this morning it must have dropped
out 15 times for one to three seconds each. Some of the buses here
(milwaukee) are actually using wifi(channel 6 i think) to determine
the current position and display it on lcds (which mostly show
advertising), and I know this morning's bus was equipped with the
annoying things. I dont recall if friday's was.

I would have hoped that I could have dropout free pcm streaming within
the same backpack at least ;) I guess I'll have to shield it, and/or
add a directional antenna to the SB.

My microwave is wholly predictable -- it starts playing
'Popcorn' (http://www.kingsleysound.com/Popcorn.html). ;)

I have a similar problem, and I am thinking of solving it along the same
line. There is allready a WiFi card in my server, so it can become a
second access point.

But I have one question: How far is your squeezebox from your microwave?

I have the squeezebox in my kitchen on a shelf about 30-cm above my
microwave, and I fear that I will have to move the box somwhere else
first before I have any chance at successfully solving my
WiFiconnection problems...
