Hello Nerius,

I simply bought a standard wireless router, turned off all services in 
it except the access list and plugged it in the LAN. The access list 
filters on mac addresses and that level of security is fine where I live.

The wireless router does have firewall, dhcp, port triggering and such 
but I disabled all of those since my FreeBSDs do all of that already.

The wireless router has one port for internet and four ports as a normal 
switch, I don't use the internet port. I just plug in the ethernet cable 
in the switch part as uplink.

I considered having a wifi nic as accesspoint in the FreeBSD main 
router, however, it was better for me to be able to place the wifi 
router for optimal range of the wifi. Turned out that the centre point 
for wifi is not the same as where the main router is....
