Polarity doesn't matter
I recently 'upgraded' to Halo 3 as I knew I'd need a disc and a re-install of my Home Hub. I duly booked a 2 hour slot and a smart, polite person arrived from 'Cube'. I explained that my problem was that the Digital Voice range of my hub was less than my old BT cordless phones. No Problem! Digital Voice is carried over BT WiFi discs!
I don't know why I believed this. So I now have wonderful WiFi coverage but poor DV. I know you'll tell me to use my old cordless phones, but I actually like DV - 2 lines and useful facilities.
I can't go back to the original configuration so now I am stringing my Home Hub from the ceiling to get the extra coverage that I need.
How do I stop being given incorrect advice about BT products? - I feel that perhaps if I could stop someone else being misled it would be worthwhile. How do I do that?
PS I'm new to this forum - sorry if I've done it wrong!
if new members to forum want information on DV then should read the FAQ

Digital voice is absolutely not transmitted via your WiFi discs. Because of the layout of my house, I have four WiFi discs and my internet is great. My new digital phones however would only work in the lounge next to the hub and in the kitchen close by. Anywhere else and they would drop out, cut off calls or just not connect at all. Talk about a backwards step BT! If you look further back in this thread you will find there is a way to get your old cordless phones working again. Good luck.
