I have a simple autonomous 1140 and would like to prevent 11a clients from associating to the 5GHz radio. How do I do this? Configuring the clients for this is not an option.
There is little to no official documentation/guidance for this and extensive searching of the threads in this community are of little help/displayed similar frustration in this regard as well. (Why is this? Perhaps it’s my nativity with 11a/n, but the official documentation covers preventing 11b—and I think even “cheapie” Linksys APs can do this.)
