Flashing DD-WRT
On the DD-WRT Wiki

Supported by dd-wrt as of = v24 06/16

First, before you do anything else, check which version of the WRT350N you have. If you have V1, you're in business. If you have V2, you're outta luck.

Flashing a virgin WRT350N with the default Linksys firmware will require a special "trailed" mini-build to be flashed first. You should use a build from the BS Broadcom folder 12874 for the initial flash. The name of this file specifically is "dd-wrt.v24_mini_wrt350n.bin". You may proceed to flash it with a generic build next, such as Mega.bin. Remember to do the 30/30/30 Hard Reset after every successful flash. It is absolutely essential.

The proper process for flashing is:


 * 1)  Read Note 1 of the peacock announcement http://www.dd-wrt.com/phpBB2/viewtopic.php?t=51486
 * 2)  Read Note 3 of the peacock announcement
 * 3)  Download dd-wrt.v24_mini_wrt350n.bin
 * 4)  Do a Hard reset or 30/30/30 on your router. You will not get a password renewal page as you have stock linksys firmware on the router still.
 * 5)  Plug a cable into the lan port of the router and your computer, and disable any wireless to the computer. Disable all firewalls and virus protection. (Setting your computer to a static IP should not be required)
 * 6)  Set your browser to 192.168.1.1. This will open up the linksys webgui
 * 7)  Enter the username admin and password admin
 * 8)  Go to the administration tab. Click on firmware upgrade.
 * 9)  BROWSE to the dd-wrt.v24_mini_wrt350n.bin file you downloaded.
 * 10)  Click on the upgrade button and WAIT for the upgrade successful message. Wait at LEAST 5 minutes
 * 11)  Power cycle your router. (very important) WAIT until you can relogin at 192.168.1.1
 * 12)  Do another PROPER Hard reset or 30/30/30 on your router (very important) WAIT until you can login at 192.168.1.1
 * 13)  Click on any tab. Reset your username/password by TYPING in a new username/password
 * 14)  Configure your router

You can now upgrade to any generic dd-wrt build except Micro. Be sure to always do a hard reset prior to flashing another build, do a power cycle followed by another hard reset after flashing, and NEVER re-use a configuration file from a previous build or another router. Reconfigure from scratch.

Initial Flash

From DD-WRT

gargoyle_1.3.13-wrt350n_v1-squashfs.bin

Grab that image from the download section

Linksys WRT350N Chipset Broadcom 4785 RAM 32 MB FLASH 8 MB

Broadcom chipsets are fairly easy to back-forth between Gargoyle and DD-WRT

Best recommendation for steps:


 * 1) download a backup current DD-WRT build you are using
 * 2) backup your current DD-WRT config
 * 3) reset dd-wrt to defaults
 * 4) from dd-wrt GUI - flash the gargoyle.bin image
 * 5) once you start the flash - wait about 5 minutes
 * 6) try to login to 192.168.1.1 - defaull password = password

If you want to go back to dd-wrt


 * 1) backup your current Gargoyle config
 * 2) reset Gargoyle to defaults
 * 3) flash the dd-wrt .bin file that you originally saved above
 * 4) once again - wait about 5 minutes for flash
 * 5) reload your backup config file for dd-wrt

DD-WRT Serial Recovery
Modified redhawk0 instructions
 * 1) Print out these instructions for Off-Line use
 * 2) Connect PC to router with a network cable
 * 3) Configure PC with a static IP of 192.168.1.10
 * 4) Connect Serial cable
 * 5) Start one of the programs from above
 * 6) Get TFTP ready with file selected
 * 7) Use dd-wrt.v24 mini wrt350n.bin
 * 8) Connect power to the router
 * 9) start a rapid fire Cntl-C as you plug the router to power
 * 10) type "nvram erase" w/o quotes, hit enter
 * 11) type "flash -noheader : flash1.trx" w/o quotes, this starts the tftp daemon, hit enter
 * 12) but have TFTP ready
 * 13) Click go or start on TFTP
 * 14) give it 5 minutes after it finishes
 * 15) then power cycle....Hard reset or 30/30/30...then config
 * 16) when it stops spitting out txt....hit the enter key...you should get a login prompt...at that point, power cycle it, hard reset...then config
 * 17) you'll see it boot up

DD-WRT vlan Info

 * Project:DD-WRT/VLAN Support

I can confirm the WRT350N v1.0 does support port-based vlan's via nvram only, the gui doesn't work. "proc/switch" is not present.
