Hi, I'm new here . Got a tablet and knew I had WiFi. I was hoping that I wouldn't have to download an update, and happily read here, and figured how to have router 'see' it, simply by restarting the computer ;-) As I was reading back posts, I came upon the term "encryption". It seemed to relate to neighbors being seen on routers? Mine is a Linksys Wireless-C Broadband with 4 point switch: Model #WRT54GS Y7 I see several others, probably neighbors , wit identifying account names but mine has a stronger signal. Is there something I can do to block them from being on my router? Is that what 'encrypt' means? I can't recall that being offered as an option, please advise how to do it. (I have had my password for a long time, it's 'tricky' and I'd rather not change it.) T.I.A. Sylvia
