Hi,
sorry for my bad english, but I didn't find any german community for openwrt.
I have running a TP-Link TL-WR1043N/ND v1 with OpenWrt Chaos Calmer 15.05.1 / LuCI 15.05-149-g0d8bbd2 Release (git-15.363.78009-956be55) as an Access Point behind a FritzBox 7490.
Mainly it's working as it should, but I found out, that some devices which are connected to openwrt via WLAN do not appear in the device list of the FritzBox.
It seems that this happens especially Android devices. Windows, Apple and other systems appear without problem.
It sees that the android devices get the same IP as another device connected to openwrt.
Directly connecting to FritzBox works fine and all devices appear in the device list.
Maybe anyone has an idea whats working wrong?
