You can use iperf to see how bad wireless thruput is. LinSSID https://packages.debian.org/buster/linssid is an easy way to find a relatively open wireless channel. Then there's spectrum analyzers that show how much noise/interference there is on wireless.. but they cost money and other than moving your laptop or AP somewhere else there isn't a whole lot you can do about interference :( I suspect you'd be better off spending your money on a better wireless card or a better AP.
