Flashing

Flashing DD-WRT

Linksys WRT400N

DD-WRT nvram=64

Files needed:

• (14289) linksys-to-ddwrt-firmware.bin - For first time flashing only
• (14289) wrt400n-firmware.bin

1. Do a Hard reset or 30/30/30 on the router
2. Set a static IP on your computer to 192.168.1.7. Subnet mask should be 255.255.255.0.
3. 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.
4. Power cycle the router (uplug the power from the router for 30 seconds and then plug it back in)
5. 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.
6. Leave the username blank and enter "admin" as the password
7. Go to administration and firmware upgrade
8. Navigate to the folder that you are using, and select linksys-to-ddwrt-firmware.bin
9. Hit upgrade
10. When you get a success, wait FIVE FULL minutes.
11. 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.
12. When you can access the dd-wrt webgui using a browser at 192.168.1.1, power cycle the router.
13. When you can again access the dd-wrt webgui using a browser at 192.168.1.1, do another Hard reset or 30/30/30 on the router.
14. Go to administration and firmware upgrade
15. Navigate to the folder that you are using, and select wrt400n-firmware.bin
16. Hit upgrade
17. When you get a success, wait FIVE FULL minutes.
18. At this point you can choose to put a different build on, depending on what you needs are.
19. Reset your computer ethernet connection to auto IP and auto DNS

Upgrading

Updating DD-WRT

If dd-wrt is already on the router follow these instructions. If stock firmware is on the router follow the flashing instructions.

1. Check for recommended builds here first.
2. Set your computer to a static IP of 192.168.1.7. (or to whatever subnet the router is on) Disable all firewalls and security. Disable wireless on your computer and only have the router connected to the flashing computer by the ethernet cable between the two.
3. Hard reset or 30/30/30 (If the router supports it, if not, reset to defults in the GUI) prior to flashing. Wait. Check for password page on re-login and change password.
4. Flash firmware. You can use the webgui except if you have a belkin router. (For belkin use tftp.exe to flash)
5. Wait...at least three minutes. Lights should return to normal. See important2, below. Failing to wait is how most people brick their routers.
6. Do a power cycle of the router. (Unplug the cord, count to 30 and plug it back in.)
7. Wait for the lights to return to normal usually about 2 minutes.
8. Hard reset or 30/30/30 again (If the router supports it, if not, reset to defults in the GUI). Wait. Check for the password page and re-login to change the password. Then you can reconfigure your settings manually.
9. Once configured set your computer back to autoIP and autoDNS.
   

Important1: This Hard reset or 30/30/30 works fine for Asus router, but you do have to power cycle after the reset.

Important2: After you flash the firmware, and before you do the hard reset, the router will be building some nvram settings. YOU MUST WAIT FOR THIS TO FINISH PRIOR TO DOING ANYTHING WITH THE ROUTER INCLUDING A HARD RESET. Usually, you can tell when this process is completed by the WAN light coming on, but it does take several minutes. Go have a beer. There are starting to be more and more people who BRICK their routers by not waiting until the nvram is rebuilt, PRIOR to doing a hard reset. YOU NEED TO WAIT!

DD-WRT Serial Recovery

To recover from a bad flash and get back to DD-WRT.....

Download openwrt-to-dd-wrt.bin, Don't worry about the name, it will get you back to DD-WRT.

Download TFTP32

Configure PC to 192.168.1.88

Install TFTP32

Set it up as server, browse to where the recovery file is.

Then in telnet(putty or hyper terminal) enter

 tftpboot 0x80010000 openwrt-to-dd-wrt.bin

and if you get a successful tftp transfer then:

 erase 0xbf040000 +0x600000
 cp.b 0x80010000 0xbf040000 0x600000

Then enter

 boot

2. Still has LAN MAC sudo matching ath1's MAC Ticket #1435
3. Security LED still doesn't come on when security is set Ticket #1434
4. Site Survey for ath0 shows double and triple the SSID's for the same MAC address Ticket #1431
5. TX Power setting have no affect Ticket #1433
6. 5 GHz rate always says auto rather then actually speed Ticket #1436

Problems Seen thus far on dd-wrt...

1. MAC address on mine are screwed up like my wrt600n. wl1 and LAN MAC are the same. They weren't in the Linksys firmware.
2. The wireless led on solid
3. Posting across 2.4 GHz Client Bridge right now. Bridged to wrt600n.
4. 5 GHz Client Bridge very unstable, won't maintain connection with wrt600n. Keeps changing the channel when reconnecting. Maybe result of reconnection.
5. Upgrade went smooth. Haven't tested client connections to the wrt400n.
6. Wireless Security LED doesn't come on when security is set.
7. 5 GHz is lacking channels when set as AP
