I have the problem that when roaming networks become disabled $ wpa_cli Selected interface 'wlan0' Interactive mode > list_networks network id / ssid / bssid / flags 0 network1 any [CURRENT] 1 network2 any [DISABLED] 2 network3 any [DISABLED] 3 network4 any [DISABLED] 4 network5 any [DISABLED] Selected interface 'wlan0' I address this by doing network_enable x in wpa_cli and it all comes back. I asked Adrian about this in the past, but it needs some debugging to pin down. - [tj]
