Motorola Droid 4 :: Staying Connected To Watch-guard Firewalls?

I am wondering if anyone else has problems keeping wireless connected to WatchGuard firewalls since the ICS update. I have an XTM 23-W and an XTM 26-W both running the latest WatchGuard firmware, version 11.6.1. I have a DROID 4 that was recently updated to ICS.Ever since then, I cannot get it to stay connected to either XTM firewall on any access point (each device has 3 available APs). It will connect, authenticate, get an IP address, and work fine for 30-45 seconds, then disconnect, reconnect, and go through the whole process over and over again.The phone works fine at Starbucks (open networks), and it works at two different locations with two different Netgear wireless routers both using WPA2-PSK with AES, the same as the WatchGuard units.I have tried using 802.11 ngb, just gb, and b by itself. When using ngb, it does it about every 30-45 seconds, with gb it makes it as much as 90 seconds, and b only does it even more frequently. With an open network, it does it every 30 seconds or so.Changing channels from Auto (it was on 11) to 2 or 9 made no difference.Changing from WPA2-PSK and AES to an open network made no difference.Having only one AP active (they have 3), regardless of which one, made no difference.On my Netgear WNR3500L at home using WPA2-PSK with AES (the same as the WatchGuard units), it works fine.I cannot figure out why this phone will not stay connected.
