Multiple DNSCrypt providers using latest list.The username field will default to "root" to match the ssh username, but you can set it to something else here for the GUI if you like.Īnd - this is a guess - perhaps it will not accept you trying to change the password to "admin" because it is a security risk!Ĥ Linksys WRT1900ACSv2 routers on 49081, 2 on 48141: VLANs, VAPs, NAS, client mode, OpenVPN client (AirVPN), DDNS, wireguard servers and clients (AzireVPN), three DNSCrypt DNS providers (incl Quad9) via VPN clients. When you reset, the dd-wrt GUI comes up and does not ask for you to enter an existing password! It is asking for you to choose a GUI password. With any reset, be patient and wait to allow a full reboot.Īs user and password, it will not take mine or root admin or admin admin Hardware Reset: While powered on after a full boot, hold the reset button for 10 seconds.ĬLI Reset: Telnet to router IP as username root and your password. This was a Linksys WRT54G that had just been reset and had not had any changes made to it yet.Web GUI Reset: Administration -> Factory Defaults -> Restore Factory Defaults (Yes, Apply). I've changed the MAC addresses for security reasons. Every other avenue of unbricking should be tried multiple times before resorting to this.įor future reference, I'm providing a list of factory defaults in DD-WRT v23 SP2. VERY DANGEROUS! You can physically damage the flash memory chip and TRULY "brick" an otherwise working piece of hardware this way. There are ways to physically short certain pins/traces inside the router in order to reset the NVRAM. On some less-supported hardware this may have unpleasant results. Some platforms will completely empty the NVRAM and depend on another stage of the bootloader or firmware to repopulate it. Here the bootloader is in charge, so getting it to clear the memory for you may have different results. Holding down the reset-button while plugging in the router achieves a different goal. If you added new non-factory variables, they should still be there after this type of reset. What it is supposed to do is return all settings to factory state. Many people think of it and phrase it that way. Normal behavior here is for it to not actually clear the NVRAM. Wait for it to return to normal operation (typically power-LED on solid). On different models you may see rapid flashing of a LED, or a red error or diagnostic LED. Press and hold the button while the router is on, and keep holding it about 30 seconds. Under Administration -> Factory Defaults Via the reset button on the router Here are the ways that you can Reset to Factory Defaults. NOTE: This will not restore firmware to a previous state, it only clears the settings. Again, do not restore setting backups from previous versions as mentioned in the forum. Because of this, you should only use this feature to restore settings on the same router with the same firmware version. When you use the DD-WRT Web GUI to save your settings to a file, you are dumping the NVRAM settings to a binary file. In the best case scenario, Firmware B will just throw an error and gracefully continue booting, but there could be cases where it errors out so badly that it bricks the router or makes it unbootable. Firmware B expects a boolean value here, such as "1" or "0". Now, let's flash the router with Firmware B, which reads the run_masq variable determine whether the router does masquerading. It is necessary to reset the NVRAM between flashes so that the new firmware encounters known values in the NVRAM.įor example, let's say that Firmware A sets the imaginary variable run_masq to "/usr/bin/masqrun", and this command is run at startup. The NVRAM is also retained between flashes of different firmware versions or even different firmware versions! NVRAM Merge needed with Hardware#NVRAM.Įvery router has a memory chip inside that stores persistent settings between reboots.
