It wasn't the wireless connection it was dropping Medicate.
I've returned the reuter to ebuyer and better late than never I got an email from Netgear today suggesting I update using BETA firmware as there is a fault. I don't like using beta firmware so I think I did the right thing by returning it.
It's a pity, as when It worked it was good. I'll have to think again if I ever buy another reuter.
