Connection Issues


Authentication for CNM_SECURE has been restored to use WPA2 protocols. You may need to accept a new certificate and/or re-enter your username and password to authenticate with the CNM_SECURE wireless network on your device.

I’ve connected before, why can’t I connect now?

If you have established a connection before but now find you have lost communication and you are following all the login procedures correctly, you may want to consider one of these limitations of wireless network technology as the source of the connection failure. 

  • Microwaves within close proximity will disrupt a once-solid connection.
  • Cordless phones operate in the 900 MHz, 2.4 GHz, and 5.8 GHz frequency range. The 2.4 GHz range would be the biggest culprit for interference with the CNM wireless network, although 900 MHz and 5.8 GHz can also interfere.
  • Wireless networks might not be installed in that area – But if you have found CNM wireless working there in the past, please report it to the ITS Service Desk (224-4357).
  • Wireless networking may be turned off on your device – Many new wireless devices have a simple button or an “Airplane Mode” setting that disables wireless networking.  Be sure this setting is not in use on your device.
  • There may be too many devices connecting to the wireless networks in the area/room where you are located.  If you are unable to connect while others around you are connected, we may need to add another access point nearby.  Please, let us know by reporting this issue to the ITS Service Desk (224-4357).  Please NOTE – Each access point requires a wired network connection with power-over-ethernet configured.  It may take several months for CNM’s ITS organization to provide funding and schedule a contractor to prepare for the installation of the access point.  But please report the need so that we can begin the process.
