Netgear N150: WLAN Clients cant connect to the internet

hi there

have N150 with wired clients and wireless clients.
the wired clients can connect on LAN and WLAN services.
the wireless clients can only connect to LAN services?!?

i dont see any restriction setting or a security option to cage the WLAN clients into the LAN.

PLEASE HELP!

i can't see any differences in the way the LAN and WLAN clients gets added to the network, because if i check the "Connected Clients" i see all clients - the LAN and WLAN, with IP adresses in the same subnet.

if iam doing a DNS LOOKUP on a WLAN client it gets the correct answer from the router. if iam trying to access a internet service via IP address, it resolves the domain name but after that it tells me "There is no internet service available".

PLEASE HELP!
