After a controller restore, every radio stays down. The restored configuration was taken before a country was set. What has to be set again before the radios can transmit?
Select an answer to reveal the explanation.
Short Explanation
The backup remembers a controller that was never told what country it is in. Your radios will not transmit until you set the country again. A guest password is not a country.
Full Explanation
Radios are not allowed to transmit until the controller has a country, because that country selects the legal channels and power. This restore came from a configuration taken before a country was set, so every radio stays down until the country is set again. A guest passphrase is not a country code and a restore does not treat it as one. The beacon interval does not enable radios and is not compared with the age of a backup. Client exclusion does not set a country when a client is removed. A restore brought back a configuration from before the country was set. Radios stay down until the country is set again. Do not troubleshoot RF first. Check one live client after the change and do not retune the rest of the floor until that client matches the result you expected. Exam caveat: set the country you are actually in. A country chosen because it unlocks a favorite channel is a regulatory problem, not a maintenance shortcut. Operational check: set the country, confirm the radios leave the down state, and confirm they use channels that country allows.
