Spent 8 hours hunting a rogue DHCP server that turned out to be my own router

I finally found it after manually checking every device on the network and realizing the guest network was handing out IPs in the same range as the main one, has anyone else dealt with a stupid self-inflicted network conflict like that?

8 hours" is rough, I once spent three days blaming a bad cable that was fine.

Friend of mine spent a whole weekend trying to fix a weird hum coming from his speakers. Took everything apart, swapped cables like three times, even bought a new power strip. Turns out his neighbor in the apartment next door had a cheap phone charger that was causing interference through the wall. @knight.mason, those three day cable hunts are brutal, but at least you didn't end up accusing your neighbor of running a secret radio station. Made him feel pretty dumb, but also kind of genius for finally figuring it out.
