our smartphones have no internet after an indefinite time. Both androids and iphones are affected by this. The notebooks work without problems.
If I pull a log from the accesspoint the concerned mobile as ip address the 0.0.0.0. In Zonedirector monitoring, the phone has still hours later a valid ip address.
On Handys the hibernate is disabled. Sometimes the phone works for hours and then again only a few minutes. Even if it is permanently on the table.
This is of course very frustrating , especially since the Ruckus support could not help us.
