Wi-Fi Not Working After Selecting a 5 GHz Operating Channel

Symptom:

After configuring the system to use a 5 GHz wireless operating channel, the system’s Wi-Fi features aren’t functional.

Problem:

If you leave the system’s default country setting as Not set, the system turns off the 5 GHz radio.

Note: Some countries don’t allow using the 5 GHz band (or allow only certain 5 GHz channels).

Workaround:

If your country allows the 5 GHz band, change the system’s country setting.

Procedure

  1. In the system web interface, go to General Settings > My Information.
  2. Select the Country where the system is located.
