EtherPeek provides the ability to capture error packets only by installing one of the special drivers located in the “Driver” directory where you installed the program. To use these special drivers, you must have a compatible network adapter and a supported operating system configuration. Please refer to the “Readme.txt” file located in that directory. If you do not have a special driver installed, EtherPeek does not capture error packets but does provide the ability to report errors on your network if your NIC driver returns error statistics to EtherPeek. EtherPeek can provide statistics on these two error types: CRC error and Frame Alignment error (Runt and Oversize error packets are only available using the special driver). If your network adapter driver does not report error statistics, you may notice that error counts don’t change in the Network Statistics window.
