Where did you get the triple_speed_ethernet_design from? Try to use the cycloneIII_3c120_dev_niosII_standard design from the files that Altera provides for the kit (here (ftp://ftp.altera.com/outgoing/devkit/cycloneiii_3c120_dev_kit-v9.0.2.exe)).

Hi, 

I am having EXACTLY this problem. I have used the standard design from the kit. I have had a field rep try the same thing, and get the same effect.    It has been a very frustrating couple of weeks, and I am starting to doubt my sanity.   I have tried the standalone lwip and I get a similar effect. Signal Tap shows packets correct on rgmii TSER_MAC statistics show correct broadcast ping statistics.   Breakpoints in low level input show no packets received as always returning a null.   Has anyone found a solution to this problem?   Any advice appreciated!
