# Receiving problems of W5300 UDP broadcast

## Question

Asked by WisJason on 2021-03-23 in Ethernet Chips.

My W5300 configuration is:

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.
