i will try if this works, thank you. after initializing the lwip stack and sending the first couple of bytes everything goes quite fast. i am sending files of ~300kb. i am downloading this file multiple times from the board with wget (windows binary) and with every single transfer the download speed constantly decreases (right tense?). from beginning 1,1mb/sec to 150kb/sec in something about ~30kb to ~100kbyte steps. after a while it completely collapses. nothing is working. netconn_accepts() blocks the whole time. i also figured out that this has something to do with MEM_SIZE and others. but i couldn't get this fixed. for instance at a size of ~500kb the above mentioned behavior appears after ~7 file transfers. with 1000kb MEM_SIZE i couldn't bring it to collapse but its getting really sloooow.
