Martin,
you have an ethernet network, an ethernet controller, a driver, a port
of lwIP, and your application.
Please post the actual wireshark capture file, not a snapshot.
Your snapshot shows retransmissions and duplicated ACKs, that is usually
a sign that frames are being lost somewhere. I would actually check the
port and driver are working OK. Did you check that with a known-good
application ?
What version of lwIP are you using ?
Where did you get it from ?
Do you use an OS ? NO_SYS=?
What API are you using ?
Do you honor the threading rules ?
Do you know there are web servers in the contrib tree ?
