Middle LED on adapters keeps on going out
The middle light keeps going out and I have paired my two adapters four times this morning and after they have paired I have put them back in the place they need to be and all three lights stay on for about ten minutes and then the middle one goes out can someone advise please.I pair them by doing the following.Plug them in next to each other then press the pair button on the first adapter wait for 120 seconds then press the pair button on the other adapter and then put them back where they should be.Does that sound correct.Do I have to press the pair button on thr third adapter which is connected to the router..How do I know what the Hardware and firmware versions are
