Are you using the "HomePlug" type networking? The ones two doors from me are preventing me from using any band on my ham radio from 7Mhz downwards, and also MW radio. they generate an incredibly strong broadband "hash" over a very very large part of the spectrum
As a reseller of those devices this is news to me and merits some investigation.
If they're 2 doors down from you there's a good chance they're on the same phase as you which would in principle make it more likely they'd cause you problems than if they were next door, but all the same I've not heard of this happening before.
Do you know the brand of homeplug, or their speed (14, 85 or 200Mbps)? Any idea what the distance is between you and them? Have you done any tests that confirm the homeplugs to be the problem?[*]
I know practically nothing about ham radio, but can I assume that the interference is via mains and not radio? (Ie that your radio equipment isn't battery powered and therefore isolated from mains?)
[*] Please don't mistake any of this for "I'm sure the products aren't at fault and you've misdiagnosed it". You sound like you know what you're talking about and I've got no reason to believe that you're wrong. I just like to know about the products I sell, good or bad. If this is a brand of homeplug we have dealings with I'll talk to the manufacturer/distributor and find out if this is a known issue, or perhaps indicates a fault. In fact I'll probably ask the people we deal with anyway, but a little more info would be useful first.
If this is of no interest to the list I'm happy to take it off-list.
