Check and Cast error on Omnet++ with INet - casting

Question

I'm trying to send an Udp message from a WirelessHost (Host1) to a StandardHost (Host3) through an AP and a Router, but I get this error message when i run the simulation (i called my network "poi"):
check_and_cast(): Cannot cast 'inet::physicallayer::INoise*' to type
'const inet::physicallayer::NarrowbandNoiseBase *' -- in module
(inet::physicallayer::Ieee80211Radio) poi.router.wlan[0].radio
(id=80), during network initialization
I started using omnet++ with Inet a few days ago, and based my code on tutorials and documentation, but i can't find a solution to this error. Any experience or solution ?
Thank you
This is the .ned code, without import:
network poi {
parameters:
#display("bgb=514,316;bgg=100,1,grey95");
#figure[title](type=label; pos=0,-1; anchor=sw; color=darkblue);
#figure[rcvdPkText](type=indicatorText; pos=380,20; anchor=w; font=,18; textFormat="packets received: %g"; initialValue=0);
#statistic[packetReceived](source=host3.app[0].packetReceived; record=figure(count); targetFigure=rcvdPkText);
submodules:
host1: WirelessHost {
#display("p=403,224");
numWlanInterfaces = 1;
numApps = 1;
}
router: Router {
#display("p=193,224");
numWlanInterfaces = 2;
numEthInterfaces = 2;
numApps = 4;
}
accessPoint: AccessPoint {
#display("p=303,217;r=2000");
}
host3: StandardHost {
#display("p=73,224");
numEthInterfaces = 1;
numApps = 1;
}
integratedCanvasVisualizer: IntegratedCanvasVisualizer {
#display("p=379,57");
}
configurator: Ipv4NetworkConfigurator {
#display("p=104,35");
}
unitDiskRadioMedium: UnitDiskRadioMedium {
#display("p=216,100;r=10000");
}
connections:
accessPoint.ethg++ <--> Eth10G { #display("ls=,0"); } <--> router.ethg[0];
router.ethg[1] <--> Eth10G { #display("ls=,0"); } <--> host3.ethg[0];
}
and the .ini file:

*.router.ipv4.arp.typename = "GlobalArp"
*.router.app[*].typename = "UdpBasicApp"

*.host*.wlan[0].mac.headerLength = 1B
*.host*.**.bitrate = 1Gbps

Answer 1

Add to your ini file:
**.wlan[*].radio.typename = "UnitDiskRadio"
Besides this you can set unassigned parameters in ini, for example:
**.app[0].destPort = 4000
**.app[0].messageLength= 100B
**.app[0].sendInterval= 1s
**.transmitter.communicationRange = 500m
