I think you must have something else going on. I never turn my router 
off--it stays on for weeks and months, whether I turn one or all of the 
computers on or off during that time.
Now once in a very great while I may see something weird, but that can 
usually be attributed to a local lightning storm, even tho the router 
and computers run off  UPSs.
