John- It sounds like you might have noise impacting the local AP on channels 1-6. Is the power and receive sensitivity the same on your laptop vs. the customer PC? That might be the reason you are seeing the difference in performance between the two. Did you run netstumbler or otherwise look at the spectrum? Any chances of a local interferer in the house or garage?

Vogel Sent: Wednesday, March 12, 2008 9:28 AM To: WISPA General List Subject: [WISPA] Some days I don't seem to know anything. Is it possible for interference to prevent a signal from showing up in a site survey in Windows Zero Configuration utility? I set up a relay AP at a home yesterday, the AP being on the roof of the garage (couldn't get a link to my tower from the house). The wireless card I put in the customers computer would not connect to (usually would not even see) the AP, although it would find APs in other homes 1/2 mile away at times. My laptop, sitting on the desk next to the computer, connected immediately, with great signal strength. BUT, if I changed the channel to either 9, 10, or 11, then the desktop unit would connect, also with great signal strength. I changed out the radio on the garage, changed the PCI wireless card in the desktop, antennas, everything, but as long as the AP was on channel 8 or lower, the desktop would usually not find it, and when it did, the RSSI was very low. My laptop however, did not have any problems connecting no matter what channel the AP was on, with excellent RSSI reported on all channels. Is there an explanation for what I was seeing? -- John Vogel - [EMAIL PROTECTED] http://www.vogent.net 620-754-3907 Vogel Enterprises LLC Information Services Provider serving S.E.
