I have a TP Link WAP and have been unable to connect this to the router/network

I can connect my mobile phone to the WAP's network (default). I did this by entering the IP Address

I cannot connect my laptop to the WAP, and have tried to manually enter the same IP address

I cannot connect the laptop to tplinkeap.net. My mobile will connect to this but it seems to go to Aerial.net , and i am expecting to connect into the WAP

The router i am using is Fritzbox and my internet provider is Zen

I am not an IT person and would really appreciate it if anyone could point me in the rigth direction

Many thanks
