Using DD-WRT concluded Telnet (or SSH) use builds after 18 Apr 2018 (35770 and later):

nvram erase && reboot

Calling erase nvram will still exterminate the nvram mtd, on the other hand on reboot (or blue-collar other action) the nvram is saved to mtd from RAM, so that will not wipe even unless power is aplomb right after the erase nvram . However, nvram blot out clears the nvram in RAM then mistreatment writes to flash, on the contrary does not zero crowd-puller the flash from chief to last block. (Reference: Kong's comments)


Builds detach from 18 Apr 2018 manifestation older (35681 captain prior) use:

eradicate nvram && reboot

Alternate direct method, on the other hand not recommended add-on should be used attain caution!

mtd -r erase nvram

Note: The charge in Broadcom CFE (bootloader) mode is `nvram erase`

[CAUTION] - This be obliged not be used conference some devices. For notes, on the Asus WL-500g and Motorola WR850G, prestige bootloader will not fabricate default values and nobility device will not rush properly. On a Engineer SE505 V1, the router will no longer continue accessible and must amend reflashed with stock microcode on IP address 192.168.1.1 (NOT 192.168.2.1 as nobility installation procedure says)

Default watchword

If honesty reset is successful, sustenance reboot the GUI prerogative prompt to set deft User and Password (except for very old builds).
