On mine, I use WPA. If your NIC supports it, thats the way to go. I also do not broadcast the SSID. I am the only one that uses my wireless network though. You could also set up MAC filtering. You can make it so only the MAC address's that are on your allowed list can access your network. MAC address's can be spoofed, so this is not 100% secure, but with all three of these things in place you should be in pretty good shape.
Rod:Sorry I did not see you post.I picked something that I would remember,even at my advanced age.Whatever it is,copy down the encrypted code for future reference,in case you have to enter the encryted code on your wireless device to gain access to your router.
In my case,I just entered the passcode and it was encrypted by Linksys and the encrypted code was displayed for me.
First off, where do you see this message? I'm assuming on one of the attached computers. How about telling us about ALL the attached devices on the router, both wired and wireless. Somewhere, a device has an IP address assigned that conflicts with one being assigned by the DHCP server. This is usually because one or more devices have fixed IP addresses.
