Overview
WRT300N v1.0 serial numbers appear to start with CNP0.
Probable 00:18:39 OUI for both interfaces, but this could potentially be incorrect (00:18:39 is an OUI on some labels anyway)

Flashing
NOTE: During configuration or flashing a device, the only things that should be hooked to the device is the computer and power. |
Flashing dd-wrt
WARNING: Do not flash micro this unit! |
WARNING: Requires K2.6 for DD-WRT, Do not flash anything else! |
Supported by dd-wrt as of = v24 - 06/08
- Download DD-WRT v24 Mini from this link: ftp://dd-wrt.com/others/eko/BrainSlayer-V24-preSP2/older/09-08-09-r12874/broadcom/dd-wrt.v24_mini_wrt300n.bin
- Read the peacock announcement found here: http://www.dd-wrt.com/phpBB2/viewtopic.php?t=51486
- Do a proper HARD reset on your router.
- Set your computer to a static IP address of 192.168.1.7 Subnet mask to 255.255.255.0
- Plug a lan cable from your computer to a LAN port on the router. Disable any wireless on your computer
- Open your web browser to 192.168.1.1
- Find any settings you might want to keep and copy them down or cut and paste them(e.g. MAC addresses for MAC filtering)
- Go to Administration, Firmware upgrade, in the linksys webgui.
- Browse to the dd-wrt.v24_mini_wrt300n.bin you downloaded, and hit upgrade.
- Wait until you can access the dd-wrt webgui at 192.168.1.1
- Power cycle the router
- Wait until you can access the dd-wrt webgui at 192.168.1.1
- Do ANOTHER hard reset on the router.
- Go in and set your user name and password by carefully typing each of them in.
- Set your computer to auto IP and auto DNS.
Flashing OpenWrt
This device is NOT RECOMMENDED for future use with OpenWrt due to low flash/ram. DO NOT BUY DEVICES WITH 4MB FLASH / 32MB RAM if you intend to flash an up-to-date and secure OpenWrt version onto it! See 4/32 warning for details. |
This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation. This means that even setting a password or changing simple network settings might not be possible any more, rendering the device effectively useless. See OpenWrt on 4/32 devices what you can do now. |
OpenWrt support for this device has ended in 2022. 19.07.10 was the last official build for 4/32 devices. |
Devices with Broadcom WiFi chipsets have limited OpenWrt supportability (due to limited FLOSS driver availability for Broadcom chips). Consider this when choosing a device to buy, or when deciding to flash OpenWrt on your device because it is listed as supported. See Broadcom WiFi for details. |
On the OpenWrt Wiki
Support started version: 7.06
Current supported version: 19.07.7

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.
- Check for recommended builds here first.
- 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.
- 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.
- Flash firmware. You can use the webgui except if you have a belkin router. (For belkin use tftp.exe to flash)
- Wait...at least three minutes. Lights should return to normal. See important2, below. Failing to wait is how most people brick their routers.
- Do a power cycle of the router. (Unplug the cord, count to 30 and plug it back in.)
- Wait for the lights to return to normal usually about 2 minutes.
- 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.
- 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!

Notes
Debricking information
Here is a thread which contains a JTAG method for debricking your WRT300N v1 and v1.1 model.
For further information about JTAG please see the wiki entry entitled TJTAG.
Post-Installation
Once you have completed all of the steps above, your router is already set and ready to be used, configured, etc.
Known Issues
- Versions 1.0 and 2.0 of this router have 4MB flash, so JFFS will not work with the standard distros. Version 1.1 has 8MB of flash so may (untested) work with JFFS
- I use static DHCP for my network and found that this page had strange errors (incorrect labels, missing radio buttons). To fix this, navigate to Administration -> Factory Defaults and then restore the factory defaults to the router.
- Relatively same issue with MAC filtering where the word "error" replaced labels.
- When editing settings on the Administration page for the first time (after flash or hard reset), make sure that you change the interface language dropdown to Simplified Chinese, then back to English. Otherwise the router will end up in Simplified Chinese until you either change it, or hard reset the router.
- If you did not hard reset the router before you installed DD-WRT, then the login information is as follows:
- Username: root
- Password: Whatever your password was
- Hard reset the router if you cannot figure out the login information. Refer here for the default login information.
- Occasionally after changing a setting, the router will lose its connection to the internet. All you need to do to restore the connection is navigate to the Administration page and scroll to the bottom and hit the Reboot Router button.
- I recommend that you change all the settings you want to change then reboot the router regardless.
Security LED
- The security LED will not light up after flashing on version 1.1. To fix this, go to Administration > Commands, type in the following and then click Save Startup:
while sleep 1; do if [ `nvram get wl0_security_mode` = "disabled" ]; then gpio enable 3; else gpio disable 3; fi; done &
As posted by osmosis
On the wiki for 150N is posted
root@DD-WRT:~# gpio enable 5 #(SECURITY LED - off - green) root@DD-WRT:~# gpio disable 5 #(SECURITY LED - on - green) root@DD-WRT:~# gpio disable 3 #(SECURITY LED - on - amber) root@DD-WRT:~# gpio enable 3 #(SECURITY LED - off - amber)
this applies for the WRT300Nv1.0 as well so to incorporate the amber into the mix as not secure: Also confirmed working on the WRT300N v1.1 WifiShadow 02:40, October 1, 2010 (UTC)
