I tested the same in an older 10-ALPHA4 laptop (running r255948 from October 2013) with the same physical WLAN card; there is no problem with the bg scans every 5 minutes, it just goes ahead after any scan; this is an issue in head. -- You are receiving this mail because: You are the assignee for the bug.
