SJ: Is it screwing with the 802.11bgn (2.4GHz) or 802.11a/ac (5GHz) WiFi ?Or both?

I don't think my (antique) WRT54G has 5GHz so I'm guessing it's in the 2,4GHz range. However I've not a clue what range the garage door and ignition/alarm fob on the bike run at. Come to think of it the house alarm system is cellular and appears to be unaffected ... Or - since some of the sensors are reporting low battery - it may be causal if it (can...) turn itself up a bit in an attempt to reach them. Alarm control, garage door and spot where bike alarm flaked are all within 30' of each other. Wireless router is quite slow, but stable-ish, and at the other end of the house.
@Curt - I do not believe that the situation is intentional. I suspect that something in the (strictly residential) vicinity is either saturating a channel, gone a tad out of spec, or both. e.g. there's no need to get the - instant over complication - Fuzz involved ... Even if I could get them to stop laughing long enough (small southern town...) to take a report.
Radio/Ham armatures never really came to mind as that type of interference always manifests differently. You can/will hear them talking over various audio devices like clock radios or TVs. Case in point, where I work there is a tow yard next door, and any time one of the drivers transmits (high-end CBs) from the yard I can hear them over the computer speakers in my office. Kinda freaked me out at first because I didn't know where "The Voices" were coming from...but I hardly notice it anymore.
