I have one hallway that has 250 hp laptops connected at n speeds. I also have 8 wireless projectors connecting at g speeds. I have 4 Cisco 1141 AP's with more in other parts of the building. We have a 2 WISM controllers set up. We have over 1500 machines total on our network with a 10MBPS optiman connection. At most times I have an average of 50 clients on one AP. How much if at all does the on-board bluetooth hurt the wireless network. I am thinking of disabling it to see if that helps with my wireless issues.
