•  If you are having problems synchronising one or more extenders, try resetting them 
to their default factory settings. Most extenders have a Reset (Link) button that 
does this. Refer to the extender user guide for more detailed information on how 
to add more powerline devices.
•  Swap devices to help check and isolate a problem with a particular broadband 
extender unit.
•  To check if your home’s electrical wiring is affecting your broadband extenders, 
try plugging in extenders in the same room. Some old wiring or fuse boxes might 
affect your network performance. 
•  House appliances that draw large amounts of power, like refrigerators, freezers, 
microwaves and air conditioning systems, might cause interference with  
your network.
•  For best network performance, use broadband extenders from BT.
•  If there are no spare ports on your router/hub, you can unplug one of your existing 
devices and use an alternative like wi-fi or purchase a switch.
