Hello all, I'm a relative novice when it comes to networking (CCNA Routing and Switching) so I figured I'd reach out and see if anyone has some advice for me. I apologize if the formatting is bad, I'm usually a lurker not a poster!
I'm working on building a lab environment to perform packet capture on wireless IoT devices. I have a Netgear Nighthawk X10 R9000 which is capable of both logging to a .pcap file as well as mirroring the WLAN port for monitoring through its debug functionality. I am slightly concerned though that we do not have any kind of granular control over the captures and no way of knowing if the router might lower the priority of the monitoring processes during periods of heavy congestion or high CPU usage.
I have also set up a second system using an Alfa AWUS036NH broadcasting as an AP connected to an Ubuntu 18.04 machine running Wireshark to perform packet capture. I figured this would give me much better control over the capture process and environment, especially since Linux allows a lot of control over its networking stack.
Is there a better way for me to sniff these packets as they move from the wireless interface into the network? We have some budget to purchase product with so paid solutions are an option, but I just want to make sure I've done my due diligence before we move forward with experimental data capture. Any help or advice would be greatly appreciated!
