Routers with "guest wireless access" do they hide the rest of the network clients from "non guest" permanent trusted clients?

Office has 3 clients on a workgroup.

Some times visitors need wireless access.

If I get a router with "guest access" different SSID - doenst this isolate these guests and protect the main group in the office ?

If your wireless router has a "guest" setting, then it may do some isolation inside via the firewall. However if the IP address is in the same subnet (likely), knowledgeable people  might be able to bypass it.

If your visitors are normal, civilized business people, the risks are very low.

If you perceive a big risk, you need to implement a switch that has VLAN's and isolate guests onto a separate VLAN.

I have a Netgear N600 dual-band wireless router with a guest network.  It has a setting where I can decide whether or not guests can have access to my local network.  Here is a description of the setting, right from the router's web portal:

Allow Guest to access MY Local Network

If Unchecked, any user who connects to this SSID can only access internet directly and other clients in the same SSID network. All clients in this SSID are not allowed to access router web GUI, clients of other SSIDs, Ethernet network and any other service of this Wireless Router.

If Checked, any user who connects to this SSID can access not only internet but also local networks of this wireless router like users in primary SSID.

Your mileage may vary on other routers, but this is how mine works.

As I noted, if your visitors are normal business types, using the guest access is very low risk, so try it out.

Hardened security generally requires VLAN's or better but not worth it in your case.
