    Hi,

    3. Use PING command to test.(Third time PING command, the module reboot)

    C:\Users\wind>ping 172.16.1.207

    Ping 172.16.1.207.32 :
    172.16.1.207 : =32 =2ms TTL=128
    172.16.1.207 : =32 =2ms TTL=128
    172.16.1.207 : =32 =3ms TTL=128
    172.16.1.207 : =32 =2ms TTL=128

    (0% loss)

    C:\Users\wind>ping 172.16.1.207 -l 1000

    Ping 172.16.1.207 1000 :
    172.16.1.207 : =1000 =5ms TTL=128
    172.16.1.207 : =1000 =4ms TTL=128
    172.16.1.207 : =1000 =6ms TTL=128
    172.16.1.207 : =1000 =3ms TTL=128
    (0% loss)

    C:\Users\wind>ping 172.16.1.207 -l 2000

    Ping 172.16.1.207 2000 :

    172.16.0.32 :
    172.16.0.32 :
    172.16.0.32 :
    (all loss and module reboot)


    4. The test equipment:
    1. Two PC (WIN10,MTU is the default value)
    2. PremierWave Development Kit and a Module
    3. A CISCO AP 2602E


    I think that issue is due to improper processing of fragmented packets.
    I want to make sure this is a configuration issue or a firmware BUG


    Thanks in advance
