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 ? _______________________________________________ lwip-users mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/lwip-users
