I changed the broadcast filter, and it continued.
Now, I have to admit to being learning impaired. The last time I had a problem, what did it turn out to be? The switch I hooked the wireless AP to. What did it turn out to be today? A different switch that I had the AP hooked up to!
I am so sorry to have taken up your time, and am very appreciative of your advice! I promise to check the switch first next time I have a problem, before I post here!
I have to believe, however, that your advice has saved me from some other problem down the road!
Again, my sincere thanks!
