I got my 868L and 865L in bridged bode to the 5500. Will see how it does with xbox and gaming. Initial configuration was a bit quirky however after figuring out that the bridges IP address changes from .50 to what ever it gets from the main host router. I think I have it figured out. Both xboxes are OPEN NAT. Mixed modes on 5Ghz using WPA2/AES only.
