Related question: I used to be able to use wifi when my microwave was running. Then one day with no apparent change it started interfering, so that I can no longer use wifi if the microwave is roughly between the two devices connecting over wifi. Of other microwaves I’ve encountered, most haven’t interfered with wifi, but one or two have. Is this a problem?
