Manual setting of IP-adress

I tried several time to set a manual IP:

the command i used is:
/httpapi.asp?command=setStaticIP:“type”:“eth”,“ip”:“192.168.10.115”,“mask”:“255.255.255.0”,“GW”:“192.168.10.1”,“dns”:[{“service”:“192.168.0.1”},{“service”:“8.8.8.8>”}]}

as there was no result, I forced a reboot with …/httpapi.asp?command=reboot
no result

even a power off/on doesn’t help…
