I've got the hub-3 unit and I have found that every six months I will have to switch the mains off/on just to re-set it. Is this the normal function of my interface equipment. It just that various computer equipments do not "lock-on" to the WI-Fi, so a "quick 10-second click" of the mains supply seems to help.
Further, is there a time of the day when BT are on-line "talking" to my Hub etc checking engineering "things".
Well I blame the "switch mode power supply"! OK they are nice, neat and small but all equipment uses them these days and you can not beat the old style of a big transformer to isolate everything and a big capacitor to smooth it all out. All the glitches on the grid are stopped from getting to your equipment, goodness knows what stuff is coming though the transmission lines.
