[RFI] Optical Network Terminal?

[Charles Plunk]

Thanks Jim. I could ditch the external SMPS for a linear solution after 
they are gone. Yep I have a cable modem to WIFI router now per your 
advice, converted all to WIFI and no RFI. So I would just be replacing 
the cable modem with the optical modem. If it does not work out or 
optical was noisy then I could switch back to cable and maybe get the 
first 12 month discount maybe, lol.
