Lan security with wi-fi open connection

I have a store which we have 2 computers for administration on the Lan and we want to give access to the internet to our customers from the same router but we are worried about security issue with a open wi-fi connection , Would you guys have a suggestion to this ? We are using a Netgear FVG318 router .

If you're worried about others getting into other than the intended then create an SSID and do not broadcast it, suppliment it with wep using a strong password.

Then make sure you're putting the wi-fi users in a different network subnet. Disable routing between your LAN and wi-fi, giving them access only to go out to internet.

Say if you're having a network for lan as 192.168.1.0 with mask of 255.255.255.0 then have the subnet for wi-fi as 192.168.2.0 with mask of 255.255.255.0.

Then make an access-list/policy to prevent communication between 192.168.1.0/24 and 192.168.2.0/24
