WAP4410N WAP - Dropping connectivity

Hi,

I'm currently having a bit of trouble with a couple of WAP410N WAPs.

The problem I have is that the WAPs drop out and can't be connected to. They become completely unresponsive and I have to reset them.

I have a couple more of these WAPs, that are working fine. They're set up identically, the port settings on my switches are identical too. Channels overlapping aren't an issue.

I managed to pull out some text from the Event Logs (see below). If anybody can shed any light on this issue, it would be much appreciated.

We moved locations and I

We moved locations and I started seeing the "stuck beacon" and dropped connectivity issues, too.  This did not happen at our old location though.

I tried all of the suggestions in the other threads, but nothing made any difference.

Then, someone suggested that it is interference with other WiFi networks in our area.

So, instead of leaving the wireless channel to "auto", I chose the value "3".  Things got much worse quickly.  I then tried other channels at random, and eventually hit upon a channel that has not had this problem for over a week, so I consider that solved for now, at least for me.

Since then, someone pointed me to the free "Wifi Analyzer" app for my Android.  That app (and I'm sure many others) very nicely shows me all of the WiFi networks in my area and what channels they are on.  Using that app will speed up your choice for a "quiet" channel.

Hope that works for you, too,

Steve
