# [W6100] Address Auto Configuration 과정중 계속반복과 긴시간 지연

## Question

Asked by k.dragon on 2023-01-13 in Ethernet Chips.

1. 시험조건
   소스코드: [GitHub - WIZnet-ioLibrary/W6100EVB-MQTT: The MQTT Example for W6100 using io6Library](https://github.com/WIZnet-ioLibrary/W6100EVB-MQTT)
   H/W: W6100 EVB V1.1
   개발환경: MX IDE or True Stduio / Hercules

2. 문제점 : Address Auto Configuration 과정중
   Wait SLIR… 에서 긴 시간 (1분이상) 지연이후
   recvfrom IP : fe80:00:00:00:d2bd:7325:85c:7734
   (시간지연)
   getSLIR() = 0x80
   getSn_RX_RSR(7) = 0x22
   size : 4
   recvfrom IP : fe80:00:00:00:d2bd:7325:85c:7734
   (시간지연)
   getSLIR() = 0x80
   getSn_RX_RSR(7) = 0x22
   size : 4
   을 계속 반복합니다.

저는 W6100관련 초보자입니다… 이문제를 어떻게 해결 해야하나요?
