Each time Linux boots on the DB410c, the wifi MAC address is different each time. Also, the wlan interface increments (wlan0, wlan1, wlan2, etc.) Searching through dmesg, here is what I found is happening:
[ 18.699448] wcn36xx wcn36xx: Direct firmware load for wlan/macaddr0 failed with error -2
[ 78.706855] wcn36xx wcn36xx: Failed (-11) to read macaddress file wlan/macaddr0, using a random address instead
[ 78.706968] wcn36xx: mac address: 00:0a:f5:60:11:d5
This prevents the board from reacquiring network access on boot up. As a work around, the user can go to Preferences … Network Connections, and edit their existing network connection, and select the new MAC address from the pull down. It will then automatically sign in to the access point.
