Ensure the channel selected is supported by the hardware and local regulations.

When you open a ticket with Ruckus, Aruba, or Cisco, the first thing Tier 2 support will ask for is a "support dump." They specifically look for ecwifi.txt to rule out EC-level problems before blaming the main OS or controller.

After resetting an AP to factory defaults, the device will generate a fresh ecwifi.txt . If the file is missing or contains garbled data (e.g., SSID1=������ ), it indicates a corrupted flash memory—meaning the AP needs hardware replacement.

If you could provide more context or details about the "ecwifi.txt" write-up you're referring to, such as its content or the specific issues or topics it covers, I'd be more than happy to provide targeted information or assistance!
