Comment 0 for bug 1569674

I installed the recent updates in the Update Manager and after rebooting I wasn't able to connect to my wifi network anymore.
It attempts to connect to the network and fails with the following error message:

Failed to update connection [network name]
connection.gateway-ping-timeout: can not set property:
value "46730064" of type 'guint' is invalid or out of range for property 'gateway-ping-timeout' of type 'guint'

I am able to use wired connection.
