If I can figure it out, I will use WEP. But I live in a rural area, and don't suspect any "drive by" users. Maybe once I figure it out, I'll use it.
I do have a modem connected to the router, and it flashes when there is activity. If it starts flashing and my computers are off, then I'll be concerned.
(Signals have to go through my modem to my DSL line)
Although maybe they could see my files, they could not uses my internet without me knowing about it, if I am watching my modem.
If I'm away, I'll just turn off the router if suspect stealing.
I tried using WEP, and I could not get a connection.[V][V]
