Dlink AP error while configuring

Hi,

I cannot set the ip address for the DWL 2700 AP , as soon as i set the
ip address , it resets and then it shows 0.0.0.0 . According to
customer service , i got it replaced but the same problem again.

I have two Ap , 1 is working perfectly alright , the second one is
giving trouble , i set the 1st 1 as dhcp server and the second one as
client and it started giving problems, this happened to last 1 also.
Now its not allowing me to change config or set the ip ...
