i get the
Network settings:
IP Address: 192.168.1.36
Subnet Mask: 255.255.255.0
Default Getway: 192.168.1.1
DNS Server: 192.168.1.1
i can ping this ip, i get response…
while getting ping responses, i can see the leds blinking on the ethernet shield…
but when i want to get any url result, i get error…
Exception in HttpWebRequest.GetResponse()
where/what is the problem?
