[Bug 78181] intermittent WPA connection

[manu]

Public bug reported:

Binary package hint: knetworkmanager

Knetworkmanager loses connectivity to a WPA wireless network
intermittently. If run on console, every time there is a disconnection,
the following message is printed:

** (process:4858): CRITICAL **: nmu_security_deserialize_wpa_psk: assertion `dbus_message_iter_get_arg_type (iter) == DBUS_TYPE_STRING' failed
knetworkmanager: WARNING: [static void NetworkManagerInfoDBus::updateNetworkInfo(DBusMessage*)] Failed to deserialize security. Probably we_ciphers are different.

Also, in dmesg, the following messages are printed:

[17240903.476000] ADDRCONF(NETDEV_UP): eth1: link is not ready
[17240906.116000] ADDRCONF(NETDEV_CHANGE): eth1: link becomes ready
