I use LwIP 1.4.1 and netconn API, allowing for example to remotely dump flash image of STM32F4 (1MB) over EDGE router so slow connection is not problem for LwIP itself - i was actually impressed that it works so well. Maybe something is not well tuned in lwipopts - have you tried to enable debug messages in lwip to see if there is no memory issue? AFAIK lwip 1.4.0 compatible driver is also compatible with 1.4.1, so consider upgrading - it is usually less to look for with more bugs fixed :) I had some issues due to watchdog (as downloading 1MB can take a few minutes), and i used switch with port speed limited to few Kbps to test it locally.
