    Hi,

      Are you running a stock Ethernet example or your own application? Can you confirm if are seeing the same issue when you run the below two examples?

    C:\ti\simplelink_msp432e4_sdk_4_20_00_12\examples\nortos\MSP_EXP432E401Y\lwip\ethernet_with_lwip (This is a Ethernet example based off of lwIP stack)

    C:\ti\simplelink_msp432e4_sdk_4_20_00_12\examples\rtos\MSP_EXP432E401Y\ns\tcpecho (this is an example based off of NDK stack)

    Hi,

      I  run the stock example C:\ti\simplelink_msp432e4_sdk_4_20_00_12\examples\nortos\MSP_EXP432E401Y\lwip\ethernet_with_lwip. After it is running, I could see the webserver page if I use my browser to view the server webpage. Afterward, I disconnect the Ethernet cable. When I disconnect, I will immediately see 'Waiting for link' displayed on the terminal window the second time and after a second or two, the 'Waiting for IP Address' will display and follow by the subsequence messages showing the acquired IP address. 

      Are you running on your own custom board? Can you try on the LaunchPad?
