A few week ago I was having issues with my internet. Reset both my Extreme and Express (both PW locked), have my network name and locked it with password. Something I've done 100x if not more. All good I think. Thing is when I click on the wifi icon, I'll see my network and I also keep seeing a network that is not password protected. Sometimes this network will show up, sometimes it doesn't. The name is the default service provider, xfinitywifi. Thats my provider. How do I know if that is my network where maybe I did something wrong when setup my network or if this network belongs to someone else who did not password protect it? When I try to join, it says I'm unable to join and wants to run a diagnostic test. Help?
