Query: Incompatible with certain networks

I purchased this router to serve a home network that contains both Macs and PCs. It replaced an Apple Time Capsule because I wanted QoS functions.However, when I installed the 655, the Windows 7 machine could no longer connect to my iMac via SMB sharing. It would just return vague errors. When I swapped back to the Time Capsule, the errors went away and everything functioned normally. I spent over two hours with a Level 3 technician from D-Link trying to resolve the problem, and eventually, after trying everything in his arsenal, we give up.Additionally, I would experience random connectivity problems with my MacBook Air, though the ipad and iphones seem to never experience issues.At any rate, I returned the unit to Amazon and will be trying something else.
