Rodent woes

The other day I was worried because my mouse (a VX Revolution) was acting up.  It was jumpy, laggy, and generally unresponsive.  Nothing I did to the mouse would make it work better.  I changed the battery - no change.  I Unplugged and re-plugged the receiver - no change.  I changed to a different mousepad, to the table surface - no change.  I was despairing, because the mouse is no older than a month, and other than that episode of unresponsiveness, it was working great.  And then it hit me.  The mouse works on the 2.4GHz band.  My router works on the 2.4GHz band.  I was, at the moment, doing a CVS checkout of considerable size.  Putting 2 and 2 together, I stopped the download, and BAM! - The mouse was working again.  Lesson learned?  Not everything wireless is wonderful.  I am still keeping my mouse - but I am considering switching my home network to 802.11n gear and let it work on the 5GHz band.
