I have an interesting issue with my wireless network. I have two wireless networks running through my building. The first is the Private Wifi and the second is the Public Wifi. Currently, I am not having any issues with my Private Wifi. Everyone in my building can connect to it and access both internet and intranet with no issues. However, the Public Wifi has started becoming an issue. When you try to connect to the Public Wifi, it comes up with the "Do you want to set up your network?" message window. Please note that it has been working just fine for the last 3 years and it is not a new network or new router. The message does give the option of connecting to the network without setting it up with allows you to connect. However, once you do connect, it cannot reach websites like Outlook Web App which has a public facing IP address with the appropriate NAT rules in the firewall to allow it to reach the server. Again, this connection works just fine on the Private Wifi. Looking at our Access Points, there is nothing that I can tell to be the issue. The other building that has the exact same equipment as this building has no issues with their Public Wifi. I compared the two sets of Access Points to see if there was a setting that was enabled/disabled on the building's APs that worked that were not enabled/disabled on this buildings APs that would keep it from working. I have everything set to identical settings minus the appropriate IP and DNS addresses for both. Also, I have the 6 APs in this building (the one where the Public Wifi is not working) set to channels 1, 6, and 11 in such a configuration that the APs with the same channels were not side by side. (ie: going from left to right on a building schematic: 1, 6, 11, 1, 6, 11). I have checked the DNS and DHCP settings and cannot see anything that would explain this. This is also happening across the board with all Windows 7 computers. However, Mac OS Sierra and Android Tablet operating systems are also having issues with connectivity to the Public Wifi, they just don't give the "Do you want to set up your network?" message. If anyone has experienced this and knows how to fix it, please impart your wisdom as I have run the gamut of my knowledge and have yet to have any success. Thank you.
