I was trying to send Facebook mssgs to friends; they were never received, and 1 was replied to by a woman who's been stalking me for a long time & has me under surveillance, rather than the person I sent it to. (It's possible she set up a phony Facebook profile.) I was told to reconfigure my router (Cisco wireless) or to check the router log for in/out info, but which would be better & how do I do it? Thanks.
