HELP: Which Router supports VLAN ? - I wish two groups cannot communicate with each other.

Hi All,

I have 5 wireless devices need to connect to the router,

I wish to separate them into 2 groups,

ie, group 1, Device A,B,C, group 2, Device D,E.

I wish two groups cannot communicate with each other.

I heard it can be done by VLAN, is e2500 can fit what I need?

how about EA3500 and EA4500?

I am using wireless G, is that mean EA4500 is out of choice even if it support VLAN?

Thanks all!
