Hi, Thanks for the reply.
I am using static ip for both the router, the nas and all wireless devices on the network. The only thing going through the switch at the moment is the nas, I use the router mainly for wireless connections for laptops and a wired connection for my desktop. Just wanted to remove the switch as i wanted the gigabit ethernet to function and the switch is not gigabit capable. Tried a crossover cable too and this did not solve the problem.
I can get a good throuput on the dir-855 wirelessly with the nas connected directly and the internet disconnected.
Regards
Brian
