I have a couple questions. You say put a router at the location.(I have not done this yet but I am seeing the broadcast packets increasing) Would this cause me to have to change ip's on anything? Would the ping tool I run still be able to ping all machines on the other side of the router? What is a small cheap router that would work in this case? Say you have 2 appo at one location. One in client bridge and one in ap mode. I should put the router in between those right?
