Flashing DD-WRT

 * 1) Read the peacock announcement found here: http://www.dd-wrt.com/phpBB2/viewtopic.php?t=51486
 * 2) Reset to defaults in the GUI (It has been reported that Hard reset or 30/30/30 does not work on this router).
 * 3) Set a static IP on your computer to 192.168.1.7. Subnet mask should be 255.255.255.0.
 * 4) Connect the lan cable from your computer to a LAN port of your router. Make sure your router is plugged in. Nothing should be connected to your computer or the router except the lan cable between them. Turn your firewall and any wireless computer connections OFF.
 * 5) Power cycle the router (uplug the power from the router for 30 seconds and then plug it back in)
 * 6) Open your browser to 192.168.1.1 by putting that in the browser address window of your browser. You should open the linksys webgui and NOT a page that says Management Mode. If you see management mode, power cycle the router again.
 * 7) Leave the username blank and enter "admin" as the password
 * 8) Go to administration and firmware upgrade
 * 9) Navigate to the folder that you are using, and select dd-wrt.v24_mini_wrt600n.bin
 * 10) Hit upgrade
 * 11) When you get a success, wait FIVE FULL minutes.
 * 12) If you don't get success, repeat from steps 6 up to this one. If you still don't get success, clear your browser cache. Try using a different browser as well, to navigate to 192.168.1.1.
 * 13) When you can access the dd-wrt webgui using a browser at 192.168.1.1, power cycle the router.
 * 14) When you can again access the dd-wrt webgui using a browser at 192.168.1.1, Reset to defaults in the GUI (It has been reported that Hard reset or 30/30/30 does not work on this router) on the router.
 * 15) At this point you can choose to put a different build on, depending on what you needs are.
 * 16) Reset your computer ethernet connection to auto IP and auto DNS

Reverting to OEM Firmware from DD-WRT

 * 8) Go to administration and firmware upgrade
 * 9) Navigate to the folder that you are using, and select WRT600N_1.01.36_build_4_20080514_US.bin once you've unzipped it.
 * 10) Hit upgrade
 * 11) When you get a success, wait FIVE FULL minutes.
 * 12) When you can again access the Linksys webgui using a browser at 192.168.1.1, Reset to defaults in the GUI (It has been reported that Hard reset or 30/30/30 does not work on this router) on the router.

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 wrt600n.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

The WRT600N and the WRT350N are very special in many aspects, they are made by Gemtek instead of Cybertan and they don't follow Linksys common standards and conventions. Both uses 539x switches and the WRT600N cfe doesn't have the vlan setup routine which all other cfe ( the 350N included) has.

 (the vlan config routine in 600N:

unsigned char bcm_robo_config_vlan (void) { return (0); }

that's all )

They are both known for "leaking" from WAN to LAN during boot because with no config the switch defaults to all ports bridged. The WRT350N has for this reason a nvram variable, read by the cfe, to disable the switch during boot but the 600N doesn't have that variable.

So how come the vlanports nvram variables gets overwritten in the 600N? First thing to know is that a cfe never writes those variables, only reads them in order to configure the switch, and in the case of WRT600N not even reads them. Therefore there must be a program module between the dd-wrt vlan gui which configures the switch and also writes the nvram variables so you get the same vlan config after a reboot. Changing the variables manually via Telnet and then issuing a reboot will cause that program to update the variables before it shuts down. You can change them via Telnet as much as you want but they will always be updated to reflect the gui settings.

do an lsmod and look for something like robocfg or switchcfg, that will be the module configuring the vlans via the gui.

working with LOM today.. this is the latest:

[3:43 PM] barryware:

<<< Breaking news....

The factory partition does nothing.. It gets the macs from the radios..

The macs match the origional sticker.. Not the cfe or factory part from the old 600.

Sticker = 00:1d:7E:0d:13:75.... 2.4 ghs radio is the sticker mac wan = 00:1d:7e:0D:13:77 Lan = 00:~:13:76 5 GHz = 00:1D:7E:0d:22:b9 which matched the lable on the radio card!

This is with stock firmware.. have not flashed anything..

There you have it!>>>>

Initial Flash May Not Work / TFTP problems
Some users may experience "Failed to Upgrade Firmware" messages when upgrading via Linksys web interface, even when using special 600N-specific builds. Also, TFTP may not work after the router has booted (Linksys fw only). The solution to both is to initiate TFTP within 3–5 seconds of power-on.
