So having been on holiday for the past 2 weeks I got bored....Floors up , holes drilled, mess made = Cat6 laid into all vital area's of the house.
I purchased 2 x Cisco 3560C-12's and these handle all my servers/pc's and camera's with relevant vlans.
Initially I had the Cat6 runs connected to the router (back on the Zyxel for now) and then into the switches but file copy speeds were not what I expected (around 150- 200 Mbps) but when I connected everything to a switch and just vlan'd off the router speeds went up to around 600 Mbps - so well happy with that !!.
