John - yes I did think of the Pringles option, but as I understand it, the can antennas are directional ones, ie. they only deal in the direction that they're pointing. This would be useless since the wireless is used all over the office and hopefully soon in church house.

Abs - I'm really not keen on replacing the DG834G we shelled out £80 for, my hope is to maybe spend £20 on a fancy antenna or maybe £40 on a repeater (or similar)

Thanks for the input so far
