I could use some networking help/advice: despite being out of town for over a week this month, comcast is telling me we've gone over our data allotment and used 1.5TB this month. According to them, our typical month uses about 600GB I've changed our wifi passwords, but I suspect that one of our internet-connected devices (air conditioner, robot vacuum & litter box, that sort of thing) has been compromised, and I’d like to try and figure out what's using bandwidth without having to disconnect things in a trial & error manner, but I'm unsure how to go about this I've got a 7-year old wifi router I've been meaning to replace, and I've been thinking about replacing it; I'd like to be able to see about how much bandwidth each device is using over a time period. How would I go about this?

@mattly@hachyderm.io Do you have root access on the router?

I found a device/bandwidth breakdown in some obscure page of the router's admin interface the dishwasher's used 700+GB in the last howeverlong, my laptop using 43GB in the same time period my partner got this dishwasher a few years ago after reading many reviews; I've never liked it much but I liked it even less after discovering you had to use the app – via the internet – to do a rinse cycle or a self-clean I'm not sure how it could have become compromised; we keep all our stuff up-to-date, I don't let untrusted stuff on the network, and the only android device we have is an MP3 player / e-reader for the kid for which you can only install apps via sideloading APKs via miniSD Then again, it's a dishwasher company writing software in the age of vibecoding, so who knows, maybe it self-compromised
