I’ve been noticing some interference with Wifi devices around my house, so I started looking for a way to troubleshoot them. I’ve tried to use a signal scanner on my phone to see if i can pick anything up but it goes away the devices come back online before i can get out to check. After some, admittedly, brief researching, i figured i could make my own signal/frequency scanner with an SDR and leaving it out in the area i believe the interference is effecting, and recording activity. After searching around a bit more, the devices are fairly expensive for the signal range i would need, for what would amount to some troubleshooting.

Which brings me to this post. I’m hoping to not spend a decent chunk of change and this not work so I’m asking to see if anyone here has experience using an SDR (in general) to troubleshoot signals in the 2.4GHz and 5GHz range. If so, would i be able to use the ADALM-PLUTO with the 6GHZ firmware download.

The setup would consist of a Raspbery Pi with PiSDR, and the ADALM on it. Ideally it could record over 48+ hours, at which i could review for interference. To then get the most bang for my buck, I would also like to troubleshoot some Android Auto disconnects that happen at very specific spots on the road, too, which Bluetooth is also in the 2.4GHz range, so this should work for this.

Would this setup work for me?
