Hey everyone! I have a question that might sound a bit silly, but I'm trying to capture packets from my WiFi IoT air conditioner for a Zabbix project. The problem is that my PC only has a wired connection to the router and doesn't have a wireless NIC, so I can't run it in promiscuous mode. I'm kind of assuming it's impossible to sniff WiFi packets this way, but I'm curious if anyone knows for sure if there's a way around this?

If the goal is just to capture some packet data, you might have a chance using ARP poisoning. This approach could let you see some packets, but keep in mind that you might only capture data sent to the air conditioner, not what it's sending out. So it has its limits!
Yeah, I think you're correct! Just keep your expectations in check with ARP.
Why not just grab a cheap wireless adapter that can run in promiscuous mode? That way, you could sniff packets while still using your Ethernet for internet access. It could be a good solution without breaking the bank!
I did think about that, but I’m a bit strapped for cash at the moment.
Another option is checking if your router can do a packet capture. Depending on its model, you might find a feature in the router settings that allows you to capture packets from the wireless network directly. This could save you a lot of trouble!
My router is a MitraStar GPT-2741GNAC-N2. Do you think it has that feature?
You’ll need to check, but I won’t hold my breath for it being a cheap model.
Are you sure this method would work? It sounds like you’d only get one direction of data.
