I have discovered that a source of RFI interferance in my home is due to my Verizon Westell 9100EM router. When I turn the device off, all the RFI silences. My question, however, is this: is it the power supply causing the interferance or the router? How can I tell? Will the alternative Actiontec MI424WR Rev E router alleviate the issue? Thanks in advance for any insight on this issue.
