I am working on an embedded system, a microcontroller-based design. The system has an Ethernet port. I am using NetX framework in the microcontroller firmware.
The DHCP Client is executed properly, an IP address is assigned correctly when connected to a router. I connect a laptop to the router using a LAN cable. Then TCP sockets behave the way they should, UDP broadcast behave the way they should. The only issue is, when I connect a Laptop over wireless to the same router UDP broadcast are received on application on Laptop, but data sent is not received on the embedded device.
Any idea why?

Platform:
Laptop is Windows
Embedded Device: Renesas S7G2, NetX framework.

    Why don't you try asking your question on StackOverflow. This community isn't exactly for posting problem solving questions.

    @joas Yeah, thanks for the suggestion. I'll try that out.

    Maybe you should ask this question on stack exchange.

    I'd remove the embedded device and replace it with a second laptop. If the behaviour is the same, the issue isn't with the embedded device, but the router config.

    @Fast-Nop : Thanks for suggesting this. I'll try this out first thing tomorrow!
