Unexpected behavior of FRDM K64F when using import SDK example

I have a weird experience with FRDM K64F

I am not sure if I am using it correctly but here are my problems

1. I am having problem running the example lwip_dhcp_freertos but requesting for IP using ethernet most of the time cannot get IP address, always stays at SELECTING

2. lwip_ping_freertos sometimes I can ping the static address, I am sure its not cable or router problem

3. both examples are from FRDM K64F SDK, but I am getting error when using a different example, when I copy the codes from gpio_led_output, I get error (I am guessing this is library problem)

4. I have lwip_httpsvr_freertos and lwip_httpssrv_mbedTLS_freertos both identical code but the mbedTLS version does not show the sub pages, only the index.html

5. I am having problem running xTaskCreate(), probably memory issue or thread stack size causing other function to fail 

most of these are based from example and/or I just copy paste from example to another example.

so I am guessing theres no mistake on code. I may have run it wrong or something.

hope someone can help this unexpected behavior

Regards

Hi Kermith:

I tried the frdm64f_lwip_dhcp_freertos demo, it can work on my side. Then I ping the board from my PC, it seems stable. Please see below picture.
