You need to set the parameter of certain modules to actually calculate the checksum. Calculating the checksum takes time, so this isn't done by default. Search for crcMode, fcsMode, checksumMode parameters, depending on the INET version and protocols you are using. |

Thanks, but I already tried setting all checksum/FCS modes to 'computed' in the INI file—no luck |

You should track down where the packet comes from and find out which module is responsible for not computing the checksum. Then you will see if that module has the capability to compute the checksum or not, and whether the corresponding parameter is set or not. You can do all of this in Qtenv while the simulation is stopped after the error. |

Thanks for your assistance. The root cause was a faulty OMNeT++ installation. Reinstalling resolved the issue. |
