It would be nice if opening the scan list triggered a rescan. In crowded AP areas, I often have problems getting connected. A contributing problem is that AP_SCAN always equals 1 if the ssid is in the scan list. A new scan is taken, my AP isn't there (usually), and it waits, scans again, and

Quoting Dan Williams [EMAIL PROTECTED]: Hmm. I blame madwifi :) Ok, just kidding. hahahaha.. However, I was just at a Hyatt in San Diego last weekend, and there were a _ton_ of access points there. 30. And ipw2200 displayed them all, and I could even connect to some. The differences

Quoting Dan Williams [EMAIL PROTECTED]: Actually, it does. When you drop the menu down, NM schedules a scan in a very short period of time, and reduces the inter-scan interval to 20s. When you haven't touched the menu for a while, it pushes the scan interval out to 20 minutes or something

Thanks for the info on scan behaviour. I was worried, because my list wasn't changing. It may be that the madwifi driver's scan routine usually finds the same ones. Wireless scans are never complete or reliable on _any_ platform. I meant to stress the comparison of using the AP_SCAN parameter

Quoting Dan Williams [EMAIL PROTECTED]: It pulls them down and enlarges the buffer a few times before failing out if the buffer required is too large. But I don't think you're hitting this for a number of reasons: 1) if ((errno == E2BIG) (buflen 10)) that means NM will stop
