- The static IP address of the PC on which your TFTP server software runs should be between 10.0.0.2 and 10.0.0.30.
- Make sure that the PC contains the access point image file (such as c1200-k9w7-tar.122-15.JA.tar for a 1200 series access point) in the TFTP server folder and that the TFTP server is activated.
- Set the timeout value on the TFTP server to 30 seconds.
On the PC where the TFTP server is located, perform these steps:
- Disable any software firewall products, such as Windows firewall, ZoneAlarm firewall, McAffee firewall, or others.
- Ensure all Windows files are visible. From Windows Explorer, click Tools > Folder Options > View; then uncheck the Hide extensions for known file types check box.
- Rename the access point image file in the TFTP server folder to c1200-k9w7-tar.default for a 1200 series access point, c1130-k9w7-tar.default for an 1130 series access point, c1240-k9w7-tar.default for a 1240 series access point, and c1250-k9w7-tar.default for a 1250 series access point.
- Connect the PC to the access point using a Category 5 (CAT5) Ethernet cable.
- Disconnect power from the access point.
- Press and hold MODE while you reconnect power to the access point.
- Hold the MODE button until the status LED turns red (approximately 20 to 30 seconds) and then release.
- Wait until the access point reboots, as indicated by all LEDs turning green followed by the Status LED blinking green.
- After the access point reboots, reconfigure it using the GUI or the CLI.
- CLI access to the unit
- Ethernet cable
- dhcp (not really needed)
- debug lwapp console cli
- debug lwapp client no-reload
- archive download-sw /overwrite tftp://10.0.0.1/c1130-k9w7-tar.124-10b.JDA3.tar
Option 3 – Controller Based
- Log into the CLI on the controller to which the access point is associated.
- Enter this command: config ap tftp-downgrade tftp-server-ip-address filename access-point-name
