# Receiving problems of W5300 UDP broadcast

## Question

Asked by Yang on 2021-03-11 in Ethernet Chips.

W5300 configuration:
IP：192.168.1.88
Gateway: 192.168.1.1
Subnet: 255.255.255.0

I have tested the router accessing to the same network segment, and I have also tested the direct connection with the computer. They are unicast and 255.255.255.255 broadcast.
But 192.168.1.255 can’t.
Ping is not offline in the whole process.

I also didn’t receive a response from the PC tool(cmd), but I received a reply from a network tool called wireshark(freeware). Please download the tool and check it out.
