Comment 13 for bug 1478592

@ldc:
- I did observe multiple times now, that killing the wpa_supplicant + reconnecting to the wifi solved the no traffic issue.
- I can reproduce it quite good in the company by changing the floor (and thus, getting a different access point with the same ssid)

- Does that workaround work for your "no traffic" situations, too? With having looked into the code, I bet the crypto WPA stuff is done with the wrong (old, before roaming) BSSID in the keys or challenge response or whatever.
