AR928X Wireless Network Adapter (PCI-Express) (rev 01) It's about 10 feet from a Linksys WRT54G and there's nothing blocking the line of sight. I'm running a 2.6.29.1 kernel at the moment; used the compat-wireless git to build the wireless stack. At random intervals (15-20 minutes or so) it loses the association completely and NetworkManager asks me to re-authenticate. This behavior seems to have gotten worse in the current snapshot. Has anyone else seen this, any ideas? -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/
