I have met a number of wireless vendors. All of them praise their Wireless LAN products and criticise the rivals.

My quesiton is this: How do you secure a wireless LAN which is connected through the WAN to a Data Centre?

VPN will be a solution to look at if the built in WEP is not sufficent for your requirement.

Well for one, put a firewall between the Data Center and the Wireless AP. Only allow needed ports for traffic.
Two, make sure to buy Enterprise class products IF you are serious about security. Most consumer grade equipment won't cut it as it doesn't offer the features of which i am going to address in the next line.
Three, Change default SSID. Change Default channel. Enable 128 bit WEP. Disable broadcasting of SSID. When generating the wep key, use random number, letter, symbols. <- this will help when people are using dictionary and brute wep key generators.
Four, Enable Mac filtering. DONOT enable DHCP on this segment.
Five, most should allow secondary authentication (cisco uses EAP). Make sure to use that.
Six, if you are connecting from a pc on the wireless end, make sure to use VPN or IPSEC on top of the regular encrypted lan.

Hope this is of assistance. Good Luck
