[edit] WARNING


This page is for the EA6500 V1. Currently, there are two versions of the EA6500 router available, the V1 and V2. The contents of this page cannot be used as a guide for the V2. If you have a EA6500 V2, check the hardware specific page or the forum for support


You should not be installing DD-WRT unless you have done sufficient reading on the process, drawbacks and recovery process listed throughout this page and elsewhere

30-30-30/HARD RESET

According to the peacock thread, EA series routers should never be hard reset (the infamous 30-30-30). Doing so can erase the CFE (bootloader) and brick your router.



The DD-WRT firmware for this router, at the time of writing this page was still in beta, so expect things to broken


It should be common practice to check the integrity of the files you are using whenever and wherever possible #

[edit] Install/Upgrade DD-WRT

[edit] Prerequisites

[edit] Find your hardware version

Before installing, check whether or not your EA6500 is indeed a V1 and not a V2. There are two ways to do this:

[edit] Check your stock/OEM firmware version

EA6500 V1 V2
Firmware version ≤1.1.29 ≥1.1.34

[edit] Check the sticker at the bottom of your router

These are what the stickers should say for the two versions:

EA6500 V1 V2 Notes
Model No. EA6500 V1 EA6500 V2
FCC ID Q87-EA6500 Q87-EA6500V2
IC ID 3839A-EA6500 3839A-EA6500V2
Rating* 12V ⎓ 3A 12V ⎓ 3.5A not definitive
Top right logo* CISCO LINKSYS not definitive

[edit] Installing from stock firmware

I've had better success with OEM FW 1.1.27 duing the handful of times I had to flash DD-WRT from stock. --EA6500v1 00:08, 23 July 2017 (CEST)

  1. Go to your router's web interface (usually @ and log in through the Linksys web page (default password is admin)
  2. Head over to Connectivity under Router Settings on the left panel and choose one of the recommended DD-WRT files under firmware upgrade (bigger DD-WRT files may work too)
  3. Click Start and Yes on the consequent dialog to begin the install process. Once done, your router will restart and the total process should take less than 5-10 minutes
  4. Head over to and you will be greeted with the Username and Password change page on the DD-WRT firmware (the password you choose here will be the password for telnet too)
  5. Done! Check the post-installation section for some useful tips

[edit] Post-install to-do (highly recommended)

  • Backup your CFE (bootloader) in case you brick your router. You can do this via the web interface, telnet/SSH or JTAG
  • Upgrade to a newer version of DD-WRT after your initial install. Be sure to Reset to Default settings before doing so. Upgrade instructions are mentioned below
  • At the time of writing this page, r32170 was the latest firmware that was stable --EA6500v1 20:16, 21 July 2017 (CEST)

[edit] Upgrade from the web interface

  1. Go to Administration > Firmware Upgrade
  2. Select Reset to Default settings from the drop down menu and select the firmware you wish to upgrade (or downgrade) and click Upgrade
  3. Wait a few minutes, do not turn off or reboot/reset the router until done
  4. You should be greeted with a Username and password change page that appears after your first-install

[edit] Upgrade from the CLI


30-30-30/HARD RESET
According to the peacock thread, EA series routers should never be hard reset (the infamous 30-30-30). Doing so can erase the CFE (bootloader) and brick your router.



30-30-30/erase nvram on the EA6500 V1
I personally have not had issues with either doing a 30-30-30 or erasing the NVRAM via the CLI which conflicts with the peacock thread. Your mileage will vary and doing so is a risk you have to consider. I suggest keeping hard resort/erasing NVRAM as a last resort and if possible try a TFTP instead
--EA6500v1 23:28, 21 July 2017 (CEST)

  1. SSH/Telnet into your router
  2. Change directory from ~ to /tmp by either of these two:
         cd ..
         cd /tmp
  3. Download firmware by:
    wget <ftp/http/https link to your desired firmware file>
  4. Wait for download to complete (no progress bar) and check the MD5 hash of the file by:
    md5sum <filename>
  5. Upgrade firmware by:
    write <filename> linux
    Do not turn off or reboot/reset the router until done
    erase nvram
  7. Reboot:

[edit] Restoring to OEM firmware

Follow the instructions to upgrade either via the DD-WRT web interface or the CLI, and use one of the OEM firmware files (select Reset to Default settings before clicking Upgrade)

[edit] Troubleshooting

[edit] Downgrading to an older firmware

Follow the same steps for an upgrade via the web interface or CLI

[edit] Bootloops/Bricks/Recovery

This is the section of this page that may be outdated or may not have the best solution. With that being said, reading more on this topic is always safer and you should be checking the following before proceeding with the instructions mentioned in this section to make sure these instructions still apply to the EA6500 V1:

[edit] Recovering via SSH/telnet (soft brick)

A soft brick is when DD-WRT is functioning and when LAN/WAN connection may be fully functional, but you cannot access the web interface and cannot fix whatever you broke or revert back to a non-buggy firmware.

In this case you can either telnet/SSH into your router over a wired connection preferably after setting up a static IP, appropriate gateway IP and subnet mask.

telnet is enabled by default, and SSH may need to enabled separately. Follow the instructions to upgrade from CLI and use a stable firmware that has worked for you or is known to be functional

If telnet is broken/disabled and SSH isn't an option either, then do a 30-30-30/hard reset to clear the NVRAM variable that might have broken your setup. This may not work if the firmware is buggy and broken to begin with. And do keep in mind that EA series routers should not be hard reset as mentioned here.

If a hard reset does nothing or seems to risky, try to TFTP the smallest OEM firmware (1.1.27)

[edit] Recovering via TFTP (hard brick; bootloops)

This should never be used as a first step if you've bricked your router.

Follow note 6 to find out if your router is even TFTP'able, and note 11 to TFTP.

I personally have TFTP'ed twice when I was stuck in bootloops and it was possible for me with the OEM FW 1.1.27. Everything else seems too large to be TFTP'ed in that short window you get before the next boot starts. You mileage may vary. --EA6500v1 02:01, 22 July 2017 (CEST)

If you cannot TFTP, then head over to the JTAG section

[edit] Recovering via JTAG/serial (hard brick; corrupt CFE)

This section is currently device non-specific and I haven't found anything of much use yet. --EA6500v1 02:01, 22 July 2017 (CEST)

[edit] Useful commands, links and scripts

[edit] Enable Cisco/Linksys LED

  1. Go to Administration > Commands and type the following in the text area:
    gpio disable 2
  2. Press Run Commands and then press Save Startup and the light will turn and stay on on every time it boots up!

[edit] Decrease NVRAM size

Text area within the web interface that is no longer being used can sometimes retain code and occupy space on the NVRAM. Doing the following will allow you to safely decrease the size of your NVRAM:

  1. Go to Administration > Commands and type the following in the text area:
    nvram show | grep =$ | wc -l
    for line in `nvram show | grep =$ `; do var=${line%*=}; nvram unset $var; done
  2. Press Run Commands and then press Save Startup and this will run the command at boot up
