View Full Version : Gotta be a way to fix this

Hi,

I think I've tried just about everything anyone has suggested, Moving
Access point to within 3 feet of the Slimp2/WAP11 closest to the
microwave, changing channels from the highest to the lowest to several
in between, and no, I have no 2.4 Ghz phones, I only use 900 Mhz phones
to try to prevent the problem.

I've done quite a bit of experimenting (based on using just what I
have, not a lab or anything) and I've found that if the microwave is
set to defrost (30 percent) the interruptions do not happen as often,
depends on when the stream is being sent vs when the 30 percent happens
with the microwave. If the music doe get stalled with the 30 percent
it will usually (but not always) recover. However when the microwave
is set to 100 percent, chances are that the music will get stalled and
not recover.

It seems that some sort of "keep alive" between the players and the
server could solve the problem.

Thanks,

AndyD

Microwaves chuck out loads of 2.4 GHz noise. It screws my sound every time
it's used, and it is a relatively new one. Just one of those things.
Now - does anyone know how to screen a microwave to slow this stuff down?

You would need a metal screen with a specfic hole diameter per screen
around the entire microwave with a screen door to get to the door. Then
ground the screen. Make sure the entire screen is grounded.

You will need to look up the correct screen hole size, the thing is
called a Faraday Cage.
