| AP reboots into controller mode | You loaded a .bin file, not the .tar. The .tar is required to convert from LAP to AP mode. |
| TFTP fails with "File not found" | Check your TFTP server’s root directory. The filename must be exact, including capital/lowercase letters. |
| AP won’t get an IP address | The default BVI interface may be down. Console in and run debug dhcp detail. |
| Radio not coming up | You may have a regulatory domain mismatch. Use ap-type autonomous in console during first boot. |
Yes – for legacy deployments. This version is stable, supports WPA2, and fixes the critical “KRACK” vulnerabilities (backported). However, it does not support WPA3 or modern TLS versions for the GUI.
No – if you have a newer AP (1800/2800/3800 series) or need modern security. Upgrade to a 9800 WLC with 802.11ax instead.
