Need help with limited connectivity on desktop

[sayplease]

ok the problem with my desktop is that its wireless connection is limited connectivity.
i checked ipconfig on cmd and there is no default gateway / dns server .

i tried ipconfig /renew and it says this.
An error occured when renewing interface wireless network connection : unable to contact your DHCP server. Request has timed out.

I am now using my laptop. No problems connecting to the internet..

I tried rebooting and reinstalling the drivers on my desktop, but it is still the same.

Anyone can help me on this? I got no idea whats wrong with the desktop's connection, the day before was just working normally. Could it be the wireless card uplorry?

Is ur desktop able to detect any wireless SSID around? Is ur security encryption and password set correctly? If everything no issue, try using fixed IP instead of dynamic for your desktop and see if that works out.

^ can detect other network, password put correctly also.
will try on the fix ip and see how it works.

try restart router..and renew your ip over at the wireless modem connection.

.if stlil cannot.. configure fixed ip on wireless connection... once connected. then reverse back to dynamic again..
