Which channels are clearer, etc. It’s not my app so I’m not an expert with it, sorry. I just know you can get lots of data with it… maybe too much. It might help to identify if there’s a device that’s transmitting with way too much power and messing up other things, especially if those other things (your little computer) aren’t able to work around it for some reason.
Microwaves make 2.4ghz interference if they leak also, but you probably don’t have one running all the time.
