a/v sender interference

[Sean]

Hi there,
sorry about all the A/V sender posts.. just some things I find confusing..

I now have the digitech wireless A/V sender which I'm using to transmit
audio ONLY... works great, except when I turn on my computer (wireless Dlink
network card) .. the strange thing is I've changed the wireless channel on
my router to a channel that does not interfere but still I get a little bit
of static every few seconds through the speakers because of my computer
wireless card.. also if I do a general wireless scan on the computer I got
lots of static noise..

Now, I thought that this may be one of those annoying things that can't be
rectified but then I tried my laptop (Acer Travelmate 290) .. the wifi on
my laptop didn't interfere at all .. even when I scanned for all networks
and put my laptop next to the a/v sender I got no interference at all...

This leads me to believe that the Dlink is broadcasting over MORE channels
than a standard WIFI (also, as a side-note my laptop has a greater
strength - I can attach to networks much further away) ...

Does anyone know if another wireless card for my PC may not interfere? ..
which one is best to get!?

Thanks in Advance

Sean
