Hello @MGOEL.1 ,
just trying to reformulate your issue to make sure I get you right.
you have a software implementation of Lwip stack running on STM32F4 MCU and you are trying to receive 14000bytes (14kb) TCP packet but with your current configuration it is working inconsistently (sometimes working well meaning receiving all data and sometimes not). please confirm these statements if it is the case and elaborate more if not.
just have few other points to ask regarding your environment setup. how are you generating the 14000byte of data, which tool or script on your computer, on which OS, and how are you connecting your board and computer via Ethernet is it directly or over a switch or via a router ...
Regards
