Some of our services appear not to be working at the moment.

Our team has been notified, and is working on sorting out the issue.

Below you will find ways to diagnose and/or fix all network interface errors.

This Interface has no IP?
If you get "this interface has no ip...etc" simply change adapters to the correct one, For example the correct adapter for me to sniff on would be the one highlighted in blue.
If all adapters show no ip, Close the tool an uninstall winpcap 4.1.3 and re-install it properly you can find the download link at the bottom of this page.
TO BE NOTED: If you use the tool via wired setup or pc hotspot method. your adapter doesn't need a ip simply choose the adapter an hit sniff.

Adapters


All adapters are missing and only Loopback is showing?
If your sniffer is only showing "adapter for loopback traffic" simply close the tool and install npcap in "WINPCAP API-Compatible MODE" The npcap version 0.9986. at the bottom of this page is recommended... or uninstall npcap all together an install winpcap 4.1.3

WINPCAP API-Compatible MODE


No Network interfaces found/you have win10pcap/winpcap 10 installed
Please uninstall any pcap (ie npcap,winpcap10, win10pcap) versions you have under control panel>add /remove programs and reboot your pc, and install winpcap 4.1.3 at the bottom of this page.
TO BE NOTED: If you don't see win10pcap/winpcap10 in your programs you can try installing winpcap4.1.3 in safe mode, or Install win10pcap an then uninstall it an reboot pc


Common erros when a invalid version of pcap is installed or pcap is not installed properly
Software is stuck in a scanning loop (ie scanning forever).
Software closes when trying to select a network adapter/interface.
software warns it was unable to load DLL "WPCAP".
Simply uninstall any pcap (ie npcap,winpcap10, win10pcap) versions you have under control panel>add /remove programs and reboot your pc. This issue is caused by not having winpcap 4.1.3 installed properly or using a npcap version higher than 9986. Please download either or below.

Downloads

Click Here To Download NPCAP 0.9986.

TO BE NOTED: if you need /want to use NPCAP be sure to install it after installing winpcap then install npcap via "WINPCAP API-Compatible MODE".
it will then uninstall winpcap and ask to reboot , Its very important that you choose not to reboot!!!
