Want the Ports to be Gigabit (need 2 min), to support 802.11n and older standards, decent security, reasonably easy to set up and above all to be reliable. Price is not an issue, but I'd rather spend £100 than £200.
Current beastie is beginning to get a little tetchy after serving faithfully 24/7 for the last 4 years and I want to buy a replacement pdq before it gives up the ghost.
