Hello,

I'm new in this forum and in this area. Please help me some advice if it is possible. So I'm working on a webserver application, and I use the lwip 1.4 tcp/ip stack. I implemented the file upload, but sometimes when I try to upload the files, get TCP retransmission and TCP Dup Ack error on network capture. Sometimes the file upload was succesfully and somtimes wasn't. I didn't find the right solution up to now.

The two captures(one when the upload was succesfully, one when wasn't) is available at this link.

Please use the following filter to see the captures between my PC and my device: ip.addr == 192.168.0.23

Please help me. Kind regards, Szabolcs
