I would also add that if you end up going omnidirectional, or otherwise have more than a handful of APs, I strongly recommend manually coming up with your channel plan. The AutoTx component of AutoRF is fairly reliable if you set reasonable limits but I've observed that auto channel selection in a congested environment has the tendency to refuse to budge. It's simply not smart enough yet to not create auto channel plans that paint itself into a corner....     I do like Auto Tx though for resiliency. In case one of your APs goes down you almost certainly want the automatic power bump to neighboring APs to reduce the coverage hole. Most wireless problems crop up after you stop paying attention to the network and it's great when the cloud can do a bit of self healing.      Oh and finally regarding RX-SOP: I have found RX-SOP to be nearly magical if you have no choice but to talk over neighboring APs that are not your own. However, if instead you are trying to get some of your own APs to talk over each other, aggressive RX-SOP settings can create more roaming problems because some clients get confused when an AP they hear loud and clear is pretending to be deaf to them. Use RX-SOP against your own APs as a last resort.  ... View more
