How does RTR affect page loading time?

Question

I connect w5300 with stm32 on FSMC. When I set RTR = 1000 the page is loaded 122 mc, but CSS and JS do not have time to boot. When I set RTR = 100, the page loads in 30 ms and I have time to load the CSS and JS, but after 2-5 update of the page the server crashes. From the register getSn_SR, the wrong values 0x10 or 0x22(udp) are read, although the socket is opened in TCP mode. What could it be? PS: RCR=2

Your explanation is too short. Add a description of what target you are communicating with, who the server is and what action you want to perform. RTR is the Retransmission Time value. If a response is not received after transmitting the packet, retransmission interval is set. I do not know what you mean page loading.

Hello, I think it will be faster to see the packet. Capture the packet with wireshark and attach it here or email becky@wiznet.io
