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

Bug description:
current build number: 68
device name: arale
channel: ubuntu-touch/rc-proposed/meizu.en
last update: 2015-07-24 08:00:20
version version: 68

My ISP (Free in France) provides a hotspot service so that customers
can use the connection of any other customer using a generic open Wifi
connection (for reference http://www.free.fr/assistance/2303.html - in
French)
The SSID is called 'FreeWifi' on all the boxes but obviously APs are
all different since it's customers' DSL routers.
When I connect to one of this access point, suspend the phone and
resume it in another location where the SSID is available but from a
different AP, the phone doesn't connect to this AP and the list of
networks in the network-indicator doesn't refresh and still show the
list of network from the previous location. I have to forget the
network called 'FreeWifi' and reconnect in order to refresh the list
and make it work.
It's 100% reproducible.
