Hey Ryan, this sounds like a very different problem and it would be good to create another thread. If the AP is dropping the 5GHZ channel altogether, that is either a "target fail" event (sort of like a firmware crash), channel change, DFS event, or something along those lines. That's quite different from the discussion in this thread, where on both bands, the radio is up and stable but the observed throughput is much worse in the AP->client direction than the client->AP direction.
