Are these units plugged into the same circuit? I'm guessing the wireless internet gear installed has a dirty power supply or a large amount of vhf-band noise being pushed back down.
A lot of cheap wall-wart power supplies (or cheap Chinese 'project' supplies) are crap. This is getting surprisingly common - even the cigarette lighter charger for my cellphone spews crap all over the VHF and FM broadcast band. I do wireless internet installs for a living, and you'd be surprised the general lack of quality control is used on most gear. I'm curious - what gear was installed?
