I'm not sure I'm in the correct forum, but I saw the word "networking" on this forum and think it's the appropriate one for my issue. I have two Macs networked together with a Linksys router. I set up the network myself, a long time ago, and don't remember much about the process. Yesterday, I had a technician come in and switch my internet connection from dsl to cable. My primary Mac accesses the internet fine, but the technician told me I would have to change a setting in my router from dsl to cable in order for my second computer to access the internet. Right now, my second computer says, "server not found." I know this has a simple solution, but I don't know how to make the change in the setting. Can someone please help? Thank you for any assistance.
