I know I need to supply more detail - still gathering all that. Just hoping someone else has seen something similar and may be be able to shortcut the problem siolving. Customer has MC3090s (CE5) running fine on the Cisco network. Now, using the same wireless configuration the MC3190 (Wm6.5) is behaving very different in the same Cisco network. The MC3190 seems to want want to roam more frequently than the Mc3090, and when it does it has trouble - it flitters between two APs and won't stay stable. The MC3090 in the same position stays stable and connected to the same AP. The wireless security being used is LEAP - TKIP.
