After upgrading to 3.5.0 we experienced mtu size issues for some applications over the wifi network. We use R500 AP's that are connected with a GRE tunnel to the SZ100 controller.
If we change the mtu of the windows client to 1300 it works fine. If we change the mtu size on the AP the application works fine, but intenet connections drop the packets.
There a two open cases @support ruckus , before the upgrade the applications works fine.
We have issues with a client vpn application and Wepresent screens (streaming).
Maybe more custommers exprerience this problems and engineering wil fix it ?
Support will not talk to engineering because they can not reproduce this problem.
