I'm not too familiar with networking and routers but I just got Cable internet hooked up today and I have 2 computers. I have a linksys router and a Linksys wireless USB network adapter. I hooked the router up to the computer with the cable modem but could not get it configured using the setup cd. I kept getting an error and just hit cancel. Then just to see what happened, I hooked the network adapter to the other computer also without configuring and to my surprise, the internet works great on both computers. My question is: do I need to go configure anything for security reasons etc? It seems to me that all the steps the setup CD had me go through was supposed to do something and I read somewhere in the instructions about my information being available to others if I did not setup something in the program but I do not remember what it said. Can anyone tell me if I'm okay the way it is now or do I need to go back and change something? Thank you.
