Hi all,

When I'm transferring a large file from my powerbook to my pc through the powerbook's airport card, I'm occasionally seeing a huge slowdown in the mouse pointer response when I move my bluetooth mouse around. If I use the laptop trackpad everything is fine...

As soon as the file finishes transferring, the bluetooth mouse is back to normal, ie. normal response when I move the mouse.

Any ideas?

Ideas? Yes.

Bluetooth operates on 2.4Ghz.
Wireless operates on 2.4Ghz.

Thus lies the problem. My machine does the same thing and seriously its most annoying.

You only notice the bluetooth lag on HUGE file transfers (where you are maxing out the wireless throughput).

Random? I use my bluetooth mouse and 2.4ghz wireless all day, transfer heaps of files. Never had a problem!

Transfer a huge file (couple hundred mb or more). The bigger the better. Whiles its transfering via wireless, move the bluetooth mouse. It will be very lazy.

Ahhh, there's the missing link - I hadn't expected/realised that bluetooth operates in the same frequency as the RF.

Most interesting...

Thanks,

Just moved 800MB's of files from my powerbook to iMac, Kept using my bluetooth mouse, if it was slower, I did not notice!

Perhaps Hawker is running his wireless on a different channel to gmask1 and iodine, and that channel doesn't have as much interference with bluetooth.
