WiFi RS21 problem

Archive

Hello,
I have a problem with connecting to internet with Wifi RS21 and Fez Spider board. On Spider, I have installed 4.2 firmware.
I found available networks, connect to password protected network, and get dynamic ip address (in my case 192.168.10.6). However, I cannot ping this address from my laptop, which is in same network. When I try to get response from web page, the socket server occures. Please help :slight_smile:
The code and output messages:

 
        void ConnectMe()
        {
            if (!wifi_RS21.Interface.IsOpen)
                wifi_RS21.Interface.Open();

            if (!wifi_RS21.Interface.NetworkInterface.IsDhcpEnabled)
                wifi_RS21.Interface.NetworkInterface.EnableDhcp();

            NetworkInterfaceExtension.AssignNetworkingStackTo(wifi_RS21.Interface);

            wifi_RS21.Interface.WirelessConnectivityChanged += new WiFiRS9110.WirelessConnectivityChangedEventHandler(Interface_WirelessConnectivityChanged);
            wifi_RS21.Interface.NetworkAddressChanged       += new NetworkInterfaceExtension.NetworkAddressChangedEventHandler(Interface_NetworkAddressChanged);
            wifi_RS21.NetworkDown                           += new GTM.Module.NetworkModule.NetworkEventHandler(wifi_RS21_NetworkDown);
            wifi_RS21.NetworkUp                             += new GTM.Module.NetworkModule.NetworkEventHandler(wifi_RS21_NetworkUp);

            WiFiNetworkInfo[] ScanResp = wifi_RS21.Interface.Scan("MyAP");
            if (ScanResp != null && ScanResp.Length > 0)
                wifi_RS21.Interface.Join(ScanResp[0], "MyPwd");
            
            Debug.Print("Connected to network...");
            Gadgeteer.Networking.HttpRequest wc = WebClient.GetFromWeb("http://www.google.com");
            wc.ResponseReceived += new HttpRequest.ResponseHandler(wc_ResponseReceived);
            Debug.Print("Waiting for response...");
        }

        void wifi_RS21_NetworkUp(GTM.Module.NetworkModule sender, GTM.Module.NetworkModule.NetworkState state)
        {
            Debug.Print("NetworkUp event!");
        }

        void wifi_RS21_NetworkDown(GTM.Module.NetworkModule sender, GTM.Module.NetworkModule.NetworkState state)
        {
            Debug.Print("NetworkDown event!");
        }
        
        void Interface_WirelessConnectivityChanged(object sender, WiFiRS9110.WirelessConnectivityEventArgs e)
        {
            Debug.Print("WirelessConnectivityChanged event!");
            Debug.Print("IP Address : " + wifi_RS21.Interface.NetworkInterface.IPAddress);
        }

        void wc_ResponseReceived(HttpRequest sender, HttpResponse response)
        {
            Debug.Print("Response is received");
            string text = response.Text;
        }

        void Interface_NetworkAddressChanged(object sender, EventArgs e)
        {
            Debug.Print("NetworkAddressChanged event!");
            Debug.Print("IP Address : " + wifi_RS21.Interface.NetworkInterface.IPAddress);
        }

Thanks for warning. Modified…

I tested code at my work, with different router works. Is there any issues with RS21, that work only with specific routers?

5

Not that we are aware of.

6

Is it possible to update firmware on RS21? What is purpose of method UpdateFirmware() ?

Thanks

Perhaps this is of use:

Also from bsaunders:

catch (WiFi.WiFiException ex)
            {
                Debug.Print("Exception was Error: " + ex.Message);
                Debug.Print("Error code: "+ex.errorCode);
                Debug.Print("Error MSG "+ex.ErrorMsg.ToString());
                Debug.Print("Stack trace: " + ex.StackTrace.ToString());
            }

Thanks for tip. I’ll try this…
