@Hank21 Yes I was having the exact same issues with my 655 walls (I have 2 ove them) All Cients on the 2.4 Ghz would start getting 100% packer loss and the whole 2.4 Ghz became unusable.

@BoboXX @Hank21 Can I get this firmware to test on my 655-Wall?

@Fae I have 4 EAP 615 walls, and wanted to upgrade 2 of them to EAP 655 walls to take advantage of the DFS channels and the 160 MHz spread since no one in my area is using DFS. I only had 2 of the 4...

@Hank21 I appreciate this firmware beta drop fro the EAP 655 Wall. I installed it and indeed, the PPSK withouth radius is working. Great throughput on the 5Ghz band, but 2.4Ghz is not usable....

@Hank21, I am also in need of PPSK support. I have two 655s that are useless to me until this is working. If I could get this firmware, it would help me greatly...thanks!
