On Monday I called Cisco SB support to ask for advanced replacements on my four WAP4410Ns. They indicated there would be a $75 charge for overnight shipping and prepaid return shipping on the four old units. I was pretty hesitant about having to pay more money to rectify Cisco's mistake, but I bit the bullet and agreed to the charge. Anything to get this fiasco over with!
This morning I received four new Rev 2 APs. So far three of them are installed and operating, with the fourth going to a remote office branch later this week. I have not noticed the original connectivity issue at all, nor any other performance issues either. I will be closely monitoring their performance and will report back with what I find. I have hope that these Rev 2s will finally make this a stable and reliable product.
The web interface states these are, "Hardware Version: Rev. 13" and are preloaded with the original Software 22.214.171.124.
On the unit itself, the PID VID label states, "WAP4410N-A V02". This was really my only indication that I had received the proper unit.
