I have not heard of any that do that. Some have adjustable power output, but they still follow protocol. The FCC rules governing use of the frequency ranges stipulate that you cannot intentionally create interference for others, and you must accept any interference that exists for you. Your only legal options are to switch frequency bands or go wired. You could also look into other options, like signal-blocking paint or metal siding.
