I have the saucer-shaped Airport Extreme, and have hooked up my DSL cable model and NAS (network attached storage) box to it. Whenever I download large amounts of stuff (e.g. >1Gb of video footage from the NAS, or try an online network speed test), the connection to my mouse gets bad. The cursor won't track well and will jump around the screen with huge latency. It seems that the worse the traffic, the worse the choppiness. I have tried this with 2 types of mice - the Apple Wireless Mighty Mouse (which was so bad I switched to a Logitech G7, using USB Overdrive X). The bug shows up on both. Note that the MM works over Bluetooth, while Logitech runs using its own USB dongle. The touchpad on the laptop is not affected. Occasionally I've also encountered situations where, while typing with my Apple Wireless Keyboard, letters will stickkkkkkkkkkkkkk for no apparent reason. Any similar experiences? (One theory I have is that the Bluetooth MM uses the USB protocol as part of its comms stack (don't know why... just a wild guess) and somehow USB Overdrive X could be interfering with it.) //markus PS. Oh yeah - I have an Intel Macbook that's 3 months old.
