Hardware/config advice - setting up small office WiFi/GbLAN network

bs217

Hi,

Just posted a wanted ad over on Adverts relating to this but I would appreciate it if anyone had advice on the following.

I'm setting up a network in a building that houses a shared office space (10+ users, 2 floors, 3000 sq.ft.) and also a public meeting area in which we want to provide open wireless internet access.

The office users will need (in addition to internet) access to printing, a fileserver and possibly NAS drives at some point. Some of the users will be doing video editing so a Gigabit LAN would be important.

Internet access will be through a DSL cable modem.

I have been looking at options and I was thinking of a 24-port Gigabit switch (plenty of ports for expansion) to which I could connect the fileserver, desktop machines, small print server and wireless access point(s). A PoE capable switch would make it easier to install the access point in any location without needing a power socket.

I'm thinking of something along the lines of these:

http://www.netgear.co.uk/wireless_accesspoint_wg302.php

since they seem to work well together (PoE, management etc.).

I'm also thinking I should probably install a hardware firewall between the DSL modem and the switch, would this be necessary/advisable?

What sort of security should I implement on the access point, given that standard WEP is not very secure?
I notice that some access points have a feature whereby public and private traffic can be segregated, should I take any other precautions to secure the office users' private traffic from public users?

I would be grateful for any advice, particularly regarding choice of hardware, management options (SNMP?) etc. from any experienced network heads.

thanks
