Recovering WAC720/WAC730 access point via the console port:
The console port provides an RJ-45 connector and supports the following settings: 115200 K default baud rate 8 data bits no (N) parity bit one (1) stop bit 1. Download the image you want to flash on to your local computer. You can get it from WAC720 product support page. 2. Download tft32d or tftp64d. You can get it from http://tftpd32.jounin.net/tftpd32_download.html 3. Unzip both the .zip and the .tar file the image let’s say in /Downloads/WAC 4. Point the TFTP server to the correct folder by clicking "Browse" next to the "Current Directory" 5. Download Putty from https://the.earth.li/~sgtatham/putty/latest/x86/putty.exe 6. Connect the serial to the Recovering AP. 7. Open Putty a. Set to correct com port (may need to check under Device Manager by clicking Start, Run, and run devmgmt.msc) b. Set speed to 115200 for WAC700 series c. Open connection 8. Reboot the AP and stop the AP in boot loader, when it shows the message “Hit any key to stop autoboot: 5.” 9. Press "Enter" 10. u-boot> nvram erase 11. u-boot> setenv serverip 192.168.0.250 Assuming 192.168.0.250 as your Tftpd server 12. u-boot> setenv ipaddr 192.168.0.120 Assuming local AP 192.168.0.120. 13. u-boot> run flash_uap_trx This Will replace image1 14. u-boot> run flash_uap_trx2 This will replace image2 15. u-boot> saveenv 16. u-boot> reset 17. AP will be flashed and boot in flashed image. After performing the steps the access point(s) will be like a factory defaulted unit with a default IP address of 192.168.0.100.
We recommend upgrading the firmware from the GUI one more time using the full AP firmware, to make sure it fully upgraded. Then add it back to the controller.
