Christian - The 450i has only been around a couple of years... surprised to hear you say it was working for 5 years on that channel.
In any case, it's really hard to tell what might be going on there. If it's under warranty, I would suggest you open a support case. That will get you the quickest action on something like this.

We have an access point that is all the sudden having trouble on channel 5840, it has been running there for about 5 years. It seems to work find down in a 5.4ghz channel for the time being, but I am looking for a possible source of interference. I have run the analyzer on the access point as well as a good number of the SM's and there isn't any out of the ordinary on that channel at all, I am about to go out looking for something but I'm starting to wonder if this is somehow a hardware issue. When running the access point in 5840 the subscribers will just connect for a second then drop off. We don't get a reading on the rates or signal, it seems very odd, especially in comparison to dealing with interference in the past, seems like some, especially the close ones, would atleast stay connected for a short time.
