How do you find the wireless network name
Do you create a new password or how do you find the password
I worked at Cox in Arizona for more than 4 years in technical support. I assisted customers with internet, cable and home phone issues. I can cover just about any questions you may have.
Depending on the router you have, both the wireless network name and the password (pre-shared key) may be listed on the router itself. The other option is something that someone had to set up. If you provide your router make and model I can advise how to get. Model is usually listed on the bottom on the router. -Andrew
