Hello Curtis,
thank you very much for your help. Your suggestion was correct, after
patching the hostapd, compiling openwrt again and inserting one line
into my hostapd config file my clients could establish a encrypted
connection to my access point.
I've also tried to understand the cause for the problem but I am not
sure if the provided answer in your link is correct. Do you know why
it isn't possible to use wlan0 in ovs with an encryption?
Best regards
Adam

You may be facing the same problem I had in the past where OVS needs
to be patched on OpenWrt for WPA authentication to work.
Patch at:
https://github.com/helmut-jacob/hostapd/commit/c89daaeca4ee90c8bc158e37acb1b679c823d7ab#diff-165dd5a1681d9394993972f6923fddf8R153
OpenWrt post: https://forum.openwrt.org/viewtopic.php?id=59129
Summary from post: For anyone else encountering this issue, the
solution is a patch to hostapd. The problem stems from hostapd
expecting to only have wireless interfaces on the internal linux
bridge. By moving the bridge to an OVS bridge, hostapd fails to see
authentication packets. The patch causes hostapd to check/add
interfaces to OVS before starting and removes them when it goes down.
Note the last comment on the forum that you need to update the
hphy*.conf file to be "bridge=br0”. By default hostapd will keep
setting the configuration file to point to the default Linux bridge
and will not work. I couldn’t figure out how to do this
automatically so I did a manual workaround to start hostapd manually
with a custom configuration file.
Cheers,
—Curtis

Hello everyone,
I'm trying to build a testbed out of a controller(floodlight), a
few switches(TP-Link WDR4300 with Open vSwitch) and a few access
points (TP-Link WDR4300 with Open vSwitch). The whole communication
is going through Open vSwitch, that includes the wireless
interfaces which were added to my Open vSwitch bridge. It works as
long as
- I don't use any encryption like wpa or wpa2 for wireless LAN.
- I exclude the wireless interface of Open vSwitch (ovs-vsctl
del-port br0 wlan0).
But as soon as I try to use a wireless interface with an encryption
wpa/wpa2 in Open vSwitch my clients wont connect anymore. Is it a
common problem?
Best regards
Adam
