Missing SSID Recently (after making no known changes) my network SSID stopped appearing in my list of available networks. Coincidently a "linksys" unprotected network with a full signal strenght has appeared. I'm guessing this is my network but how do I get it so appear as such and get it back to a protected network? Thanks Justin

Well more then likely someone reset your router. now securing it again will depend on the model but typically from the internet explorer window type in the address bar 192.168.1.1 it will prompt you for a username and password username by default is "admin" and leave password field blank and click ok. this is for most models.(if you are not able to access this you are going to need to find the manual or get then model # and goto linksys.com to find the default password for that model"
from here click on "wireless" at the top then click on "wireless security" here you can choose the security mode either wep or wpa enter your encryption key click save settings and now your router is protected again.
If you still are having problems write back the the model # and I or someone else will be glad to help you.
