Please excuse my lack of knowledge with regards to routers and wireless security. I have a very simple network setup:1 laptop Linksys DSL modem BEFW11S4
The connection between my laptop and the router is wireless. I have been using this for a year or so with no problems. I recently updated the firmware for my router. I noticed that the default for Wireless Security is Disabled. Should I enable Wireless Security? If so, should I go with WPA?
If I go with WPA, it allows me to enter a "key" and also a "Group renewal period". My questions are: How important is the key? Is it important to use a large key and remember it? Do I need to enter a Group renewal period? If so, what is a reasonable time period to enter? And finally, will I need to do anything to my laptop to allow it to connect to the router and hence the internet after I enable WPA?
TIA for any help, Bill
