We are about to pull these things out. TAC cannot find the problem. Customer had ap350s and runs fine over their wan. Tried to put h-reap with local switching and it has been nothing but a nightmare. clients disconnect from ap yet controller shows them associated and authenticated, remove from controller and client returns. Upgraded controller to 4.1 same result, changed aps, wireless cards and nothing solves the problem. it can be one client or 10 clients,it doesn't matter. All we are doing is running continuous ping. Have tried wpa, wpa2, and wep with the same result.
