Bluetooth wireless mouse very sluggish when there is moderated network activity

[Ismail Dönmez]

Hi all,

I got a Bluetooth wireless mouse identifed as,

input: Microsoft Microsoft� Wireless Notebook Presenter Mouse 8000 
as /devices/pci0000:00/0000:00:1d.1/usb3/3-1/3-1.3/3-1.3:1.0/input/input12
input: USB HID v1.11 Mouse [Microsoft Microsoft� Wireless Notebook Presenter 
Mouse 8000] on usb-0000:00:1d.1-1.3

Problem is when there is a moderate traffic on wireless interface (300-400k/s 
down 50-60k/up on 4Mbit) mouse is really sluggish. This is when I am running 
ktorrent. If I stop the torrent download/upload its fine again.

Any idea how to debug this, or why it might be happening. Btw I confirmed this 
behaviour on

kernel 2.8.18.8, 2.6.22, 2.6.23 and latest GIT tree.

P.S: If it matters I am using ipw3945 driver with 2.6.18 kernel and iwl3945 
with the newer ones.

Regards,
ismail

Hi Ismail,

it would be great if you'd be able to isolate what is the cause in a 
little more detailed way - i.e. try a different network card in the same 
machine, try a different bluetooth mouse in the same machine, try the very 
same mouse and network card in a different machine, etc.

Otherwise I am afraid this is going to be just a totally wild guessing.

Thanks,
