Some how I was viewing my wireless connections and accidently removed one of my channels. I have a regular channel and a guest channel. I accidently removed my guest channel and I want to know how to get the computer to recognize that it exists. The guest channel registers on my phone and it registers on my neighbors computer but it does not show up on this computer. How do I correct this? Every other mistake I've made has been able to be undone, How do I undo this?
