Late response, but I wanted to chime in. You don't even need a spectrum analyzer, use stumbler and any 11b device in a laptop, watch the noise floor/disassociation.
Ive seen it happen when people accross the street use their microwave. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Wayland Sothcott Sent: Sunday, November 23, 2003 4:46 AM To: [EMAIL PROTECTED] Subject: Re: [smartBridges] MAC ATTACK on airPoint PRO Outdoor? I am suprized that an oven would affect specific channels. I am also suprized that it would crash the AP. This makes no sence to me. Please explain your reasons (logic or experiences etc) for saying this happens.
