Client isolation in TP LINK router

I have bought TP-LINK TD-W8151N 150Mbps Wireless N ADSL2+ Modem Router.
On my wifi network, devices are not able to connect to each other. Internet is working fine, but inside LAN , local connections are isolated.

I cant find the setting to disable client isolation on my router. Can you help me out ?

I have consulted our engineer about your problem, they told me that on this modem, this is no client isolation function. As you said that devices are not able to connect to each other, you can try to change the wireless security encryption as AES, version choose WPA-PSK.
If you need any further help, please feel free to let me know.
