extenders flashing all the time

[tony212]

the extenders we have (3) all flash and don't really add anything to the wifi coverage.  What can we do?  We have rebooted the router etc and all the devices

@tony212 any extenders or boosters have to be close enough to the Sky hub to get a strong signal. They are normally best placed no more than halfway between the hub and where you need the boost. If absolutely necessary you may need to daisy chain extenders but this should becavoided as each jump reduces tge speed an extenders can provide. There are homes with solid internal walls which are so wifi unfriendly that they ate almost impossible to network just using wifi. 

Placing boosters in halls and on landings can help.
