![]() ![]() ![]() If there isn't a switch, then use a hub or TAP. If there is a switch between them, you can create a mirror port and direct mirror traffic to the laptop. The simplest way to capture packets is between the stand-alone box and the router. Confirm settings have been configured as expected. Capturing Wi-Fi can be challenging because it is not plug-n-play.Optionally configure a username & password for the remote sniffer.Define the IP address of the remote sniffer (host where you are running Wireshark).Youll want to capture traffic that goes through your ethernet driver. It is possible to enable packet capture via the cloud interface if you have upgraded to ExtremeCloudIQ Pilot (Manage > Tools > Packet Capture). Open Wireshark Click on ' Capture > Interfaces '. Second, some commands need to be entered on the AP via CLI. The steps described below were configured and validated on an Extreme AP650 running v10.0r8.įirst, the remote packet capture feature is supported in Wireshark for Windows and NOT in Wireshark for macOS (as of v3.2.3), therefore use Wireshark on Windows to perform the steps below. The AP650 is an enterprise-grade 4×4:4, 802.11ax access point. We move onto the steps necessary to setup a remote packet capture using an Extreme AP650. In addition, be mindful that frames can be injected into the airwaves by rogue devices, adding frames to your capture that were not actually transmitted by the devices you care about.Ĭapturing from an interface on the AP, may allow you to capture OFDMA or MU-MIMO frames they might otherwise be missed due to WiFi6 client behavior that could disregard resource unit’s (RU) not intended for the receiver. For example, if the capturing device is located closer to the AP, you are capturing from a different RF environment the frames captured as successful vs failed may be significantly different from what the client, far from the AP, experiences. Sometimes any packet capture is better than no packet capture, as long as you understand what is being collected and more importantly, what is missing. Whether it's possible to do so using the WiFi card on your laptop is unknown, because not all cards support. In a nutshell, you need to be able to capture packets in monitor mode, and you're not doing that. It’s often thought that it’s best to position the packet capturing devices as close to the client as possible. Is it possible to capture these packets using a laptop using Wireshark Yes, but your capture setup is almost certainly incorrect. ![]()
