Fair enough, but in this case there are several massive red flags that OP was experiencing a variant of "targeted individual" delusion. (The confidence without evidence that their neighbor was a determined hacker group, using a complex zero-day to attack them at home personally, tie-ins to fear/belief of this being a widespread phenomenon).

I had a stretch of a year or so a decade ago where I was going through something very similar, down to the belief a hacker group was targeting my WiFi network despite the great lengths I was going to secure it during the setup process inside an RF shielded area, yet they still kept "getting in" somehow... so I recognize the signs.

If OP can re-read their comment later on in a different mindset, they may start to notice things that felt so certain at the time don't actually add up logically in retrospect, that's how I ended up breaking out of it eventually.

Modern 802.11 implementations are wildly complex. The output from `iw list` on a Linux system with a modern WiFi radio, a trip through the example configuration that ships with `hostapd`, or perusing the lengthy list of standards, amendments, and extensions on Wikipedia will reveal it, too.

Given the complexity of modern 802.11 protocols and the prevalence of WiFi radios in devices of all kinds, I find it well within the realm of possibilities for anyone to observe 802.11 traffic that is sufficiently ambiguous to create the confidence necessary to be a mentally workable substitute for evidence of a targeted attack. There may be a lot of evidence that could be found to refute that very same premise, though, if one knows what to look for.
