in LAN under router there is static ips are configured,

all connections are working properly and internet also is working very well, except a specific ip which is "" which was working properly 5 hours ago.

but now while setting this ip in "wireless adapter", the ip can not be assigned. and after setting other ip its working, and pinging that ip eg. "ping" it returns "Request timed out.". and i want to set "" ip to my laptop which is my reserved ip, what is the problem i'm facing ?

have you tried "ipconfig /renew" "ipconfig /release" from the cmd prompt? Or turn off the wireless adapter, set the ip address and then re-enable the wifi adapter? If the ip isnt in use, you should be able to use it from the laptop. – Logman Aug 10 '13 at 23:27
