As soon as I Switched to Verizon Fios more than 5 years ago , My Home Wireless Intercoms STOPPED WORKING.
The Individual Intercoms purchased from Radio Shack worked very well , One in each room and they plugged in into the household electrical wall outlets , voice was carried via the house electrical system.
The only FIOS items Plugged in into the Household Electrical are The FIOS Panel , One Moden and One WI-FI Extender which I added 2 years ago.
Has this happened to you and how did you fixed it ?
