Guys I need some help debugging my network, my home LAN. I am using an airport extreme and airport extreme as a repeater/extender. Clients connected to my lan: iphone 4s, ipad mini, occasional laptops (mac, windows, linux) all connected wireless and a linux home server connected by rj45 running file server, time capsule, nothing extreme. My network speed inside my lan is really slow, REALLY slow. File transfers are slow, connecting between computer are really slow. Distance between airports are 5meters distance, what info can I gather to find where is the bottleneck??
