Hi, what is the best practices in this case. Use wired data and wireless data in the same vlan? or use differents vlans for wired and wireless data connections?

I have this doubt but a think that the correct is use on vlan for each, wired and wireless cause the wired broadcast can to disturb wireless performance.

am I right?

That is correct however if its a very small wlan implementation and its generally a layer 2 network you would be ok with just a single VLAN.

Rez,

If you look under the controller tab you will see "broadcast forwarding". If this is disabled wired broadcast will stop at the controller...

So make sure this is disabled and you should be ok ...

good luck

I think this is more of a security issue. I like to restrict my wireless users with a firewall just incase there are issues. I would not want somebody to hack into my wireless network and have local access to my wired data network/users. If there is not a firewall at least there is another hop between the wireless and wired users.

I am not sure about the broadcast issues but I still will not recommend the 'one vlan' solution.
