BT Extenders Connect Fine - then Data light drops after a couple of minutes
I use 4 x BT Powerline Extenders (3 x Flex 1000 - 1 of which is connected to Home Hub 6 and 1 x Mini-Connector) with my Home Hub 6.
All extenders connect connect/link fine with the 1 Extender connected by Ethernet to the Home Hub 6. 1 Extender Flex is plugged in upstairs and connects via Ethernet to a Laptop. The data light is constant and there are no issues with this.
The other two extenders are in other rooms of the house to provide wireless wifi extension. The problem I have with these is once connected to the Home Hub Extender and moved to the relevant room, the data light comes on and everything is fine for a couple of minutes. Then the data light drops out and the power light begins to flash slowly as if in power-saving mode. The data light will not then come back on unless I power off and on again.. I have tried different rooms, swapping the extenders, resetting to factory default, but always the same - the wireless extenders connect fine and then the data light goes out.
Am I doing something basic wrong here - or are there any solutions?
