we have wireless clients showing over 300mb wireless connection. yet they are extremely slow. packets trasmitted received are low. also, we connected an AP to a 7100's point and spanning tree blocked the port. how do check if the access points are tunneling:
How many clients on the AP? What upstream bottlenecks? Just because you connect at 300Mbps doesn't mean you have that available to you. Remember, an AP acts like a hub, not a switch, so if other clients are active it impacts you.
