Comment 9 for bug 1478319

Reproduced on bq 4.5, OTA13. I created two APs with SSID "Ubuntu", same password, same authentication. I connected to one of them:

phablet@ubuntu-phablet:~$ nmcli d wifi
* SSID MODE CHAN RATE SIGNAL BARS SECURITY
   Ubuntu Infra 1 54 Mbit/s 100 **** WPA2
* Ubuntu Infra 11 54 Mbit/s 91 **** WPA2

phablet@ubuntu-phablet:~$ ifconfig wlan0
wlan0 Link encap:Ethernet direcciónHW b8:64:91:47:21:b6
          Direc. inet:192.168.43.189 Difus.:192.168.43.255 Másc:255.255.255.0
          ...

Then I removed the AP in channel 11. After waiting for some minutes to make sure we had re-scanned:

phablet@ubuntu-phablet:~$ nmcli d wifi
* SSID MODE CHAN RATE SIGNAL BARS SECURITY
* Ubuntu Infra 1 54 Mbit/s 88 **** WPA2

It looks like the connection has moved to the other Ubuntu AP, but ping does not work, and the interface address has not changed:

phablet@ubuntu-phablet:~$ ifconfig wlan0
wlan0 Link encap:Ethernet direcciónHW b8:64:91:47:21:b6
          Direc. inet:192.168.43.189 Difus.:192.168.43.255 Másc:255.255.255.0
          ...

Apparently the IP configuration has not completed properly. I was able to return to a working state by doing

phablet@ubuntu-phablet:~$ nmcli d wifi connect Ubuntu
