I don't have the slightest idea on Windoze, but I happen to know that networking is networking, frames are frames, and hardware is hardware. You are likely to have: * a hardware problem, triggered by the difference in full-duplex/half-duplex and/or 10/100 due to different wiring and PC hardware * an Ethernet driver problem, triggered by the difference in the arrival speed of frames * a broken TCP application You should: * check your hardware with proper instrumentation, or have a known to work hardware. * check your Ethernet driver, or have a known to work driver * check your port, or have a known to work port. * use a known to work TCP example, as the echo server
Once you have checked that (not necessarily in that order), if you still get "lots of retransmissions and dropped packets", please post a capture file and give details on who is who and I will try to help. _______________________________________________ lwip-users mailing list lwip-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/lwip-users
