Which frequency is the mouse working on? something in the 2.4GHz region?

I remember having lots of fun at $office with the mouse of colleague.
It used channel 6 and the amount of traffic generating over wireless
LAN had direct influence on the accuracy of his mouse activity ;)

Anyways, if you have the chance to switch to another channel, give it a shot.
