Compaq 1200 Sound crackles with wireless PCMCIA card

I just installed a dlink router on my network which works great.  Then I dropped a D-Link DWL-650+ PCMCIA Wireless LAN card into my Compaq 1200-XL106, which connects fine, but everytime it transfers data over the wirless, my speakers crackle rather loudly.  When I mute the sound card the speakers continue to crackle, but they do not ever do it with any other pcmcia cards, just with the Wireless Lan.  I tried a different make of wireless card to discover that it did the same thing, only the crackles are in a different key.  *Sigh*

Any suggestions on how this may be remedied, other than upgrading my old laptop?  Thanks!

have you tried changing the channel of your wireless network?, this might help, other than that the only thing i can think of might be to try some kind of Faradays cage around the wires for your speakers so that they are protected from radiowaves, ie wrap a fine wire mesh round the wires and then cover with an insulator such as elecrical or self-amalgamating tape to prevent any shorts from othe pieces of hardware. This will prevent induced current in the speaker thus eliminating crackle.

middenface,

I have tried changing the channel with no result.

I haven't had time to try the physical solution, but will do so when I have the opportunity.  Thank you for your suggestions.
