In order to use one of these experimental builds, you must ALREADY HAVE dd-wrt installed on your router using the instructions above.

-These builds should not be used for generic users. Newer is not always better. If you don't know where to find these newer builds, search in the forum. If you don't know how to do that, you likely should stick with the basic install process.+==Notes==
 +* The E-series Linksys units have poor ventilation, so cooling can be very important to its performance. [http://www.dd-wrt.com/phpBB2/viewtopic.php?p=475684#475684 'buddee' has a nice and easy mod] that will improve air flow for under the unit.
-= DD-WRT E2000 Build information =+* After further study, the E2000 was found to have an EIRP rating of 17dBm, so it is best to run these units at a TxPower of 50mW (50mW = 17dBm) instead of the dd-wrt default 71mW. This can be adjusted in the webgui (Wireless > Advanced Settings), which should help the unit run cooler and have less Tx/Rx errors.

-Also it has been asked about the builds with e2k-e3k name in them, these builds are for if you already have those units flashed with dd-wrt AND ARE THE ONLY ONES YOU CAN USE TO FLASH THIS ROUTER IF YOU HAVE DD-WRT ON IT. You MUST use one of those e2k-e3k named builds to upgrade, but the initial flash should always be done with the trailed build (build with the unit only name in it) linked above.

- +
-===Some useful tips===+
- +
-* I have noticed with these style of linksys units, cooling can be very important to its performance, thus I have done a nice easy mod that will allow air flow for under the unit. Check this post for details. http://www.dd-wrt.com/phpBB2/viewtopic.php?p=475684&highlight=#475684 -buddee+
- +
-* After further study, I have also found that since the E2000 has an EIRP rating of 17dBm it is best to run these units at a TxPower setting 50mW instead of the dd-wrt default 71mW. 50mW = 17dBm Which can be adjusted in the webgui under the tabs Wireless > Advanced Settings enter 50 in the Tx Power entry. This should make for less Tx/Rx Errors and help the unit run cooler.+
- +
-* If you experience disconnects from the Internet/Network with this router feel free to try the following settings:+
 +* If you experience wireless disconnects, try the following settings:
Wireless > Channel > Ch 161 (5GhZ) Wireless > Channel > Ch 161 (5GhZ)
Wireless > Channel > Ch 9 (2.4GhZ) Wireless > Channel > Ch 9 (2.4GhZ)

 +* If you are having trouble doing a hard reset using the 30/30/30 method, you can try using the wrt320n hard reset method instead. It has been confirmed to work on the E2000 as well. [https://www.dd-wrt.com/phpBB2/viewtopic.php?p=525357#525357 [buddee]]

-* buddee suggested if you are having trouble doing a hard reset using the 30/30/30 method, you can try using the wrt320n hard reset method instead. It has been confirmed to work on the E2000 as well. Check this post for details. http://www.dd-wrt.com/phpBB2/viewtopic.php?p=525357#525357+*The Broadcom 4717 SoC uses a default clock of 300MHz, but the Linksys E2000 runs at 354MHz. The increased heat can reduce routing performance, and may be responsible for many of the wireless errors reported in the forum. It is suggested to add a heat sink and/or improve ventilation. Alternatively, set the CPU clock to 300MHz, but this will reduce max throughput and slightly increase latency. From telnet/SSH or GUI ''Commands'':

- Unplug power cable+
- Hold down WPS button+
- Plug power back in+
- Continue holding WPS button for 12 seconds and release+
- +
-'''NOTE'''+
- +
-This router uses the Broadcom 4717 CPU. Broadcom uses a default clock of 300MHz for the CPU, while Linksys has overclocked the CPU to 354MHz. This not only causes excessive heat which reduces routing performance, but is also responsible for many of the Wireless errors reported in the forum. It is suggested that you set the CPU clock to 300MHz until the developers have acknowledge the problem, and newer builds are released to fix it.+
- +
-Open up a telnet or SSH prompt and login to your router. Type the following:+
- +
nvram set clkfreq=300,150,75 nvram set clkfreq=300,150,75
- nvram commit+ nvram commit && reboot
- reboot+
- +
-===VLANs Support===+
- +
-It is also known for the E2000 to support VLANs. Also note that in order to adjust VLANs from the webgui with the E2000 then you will need build 15508 or better, which should be available through the above posted FTP links. Please refer to these wiki links for further info regarding configs.+

- +
-http://www.dd-wrt.com/wiki/index.php/VLAN_Support+
- +
-===Reverting back to stock firmware===+
-It has been asked about how to revert back to stock firmware, why would you ever want to do that?!? You can always flash back to dd-wrt anyhow, to revert back to stock firmware simply download the latest E2000 firmware from linksys site, reset you router to defaults from within dd-wrt's webgui, wait, then login and select the stock firmware file and flash, make sure to select "reset to defaults" on the drop down menu when flashing.+==VLAN Support==

Only flash builds under 7936 KB (7.75MB) (8126464 bytes) or you will brick your router.

[edit] E2000 Flashing Instructions

WARNING: Only use the trailed builds (with 'e2000' in the file name) for initial flashing or it may result in a bricked unit!

[edit] Initial Flash from Linksys firmware:

  1. READ the Peacock Announcement carefully!
  2. Disconnect all cables and wireless clients.
  3. Do a hard reset.
  4. Connect a LAN cable to the PC doing the flash, then access Linksys GUI at 192.168.1.1 via web browser.
  5. Go to the Firmware Upgrade page to flash the 21061 E2000 trailed build
  6. Wait 10 minutes until WLAN (wireless) light turns on.
  7. Power cycle by unplugging E2000 for 30 secs.
  8. Plug back in and wait about 5 minutes until it finishes booting.
  9. Do a hard reset.
  10. Wait 3 minutes and log into web interface.
  11. You are done. There is no requirement to flash any other build.

[edit] Upgrading DD-WRT firmware:

  • NOTE: Use K2.6_mini-nv60k.bin, K2.6_big-nv60k.bin, or K2.6_mega-nv60k.bin files.
    • DO NOT use any other files or you WILL BRICK YOUR ROUTER!
    • Newer is not always better! Research new build and E2000 threads before flashing!
  • See Where do I download firmware? for more info.
  • K3X builds (kernel 3.x) are available; use the K3.x_mega-e2000.bin or K3.x_mega.bin from the broadcom_K3X.
  1. Navigate to 192.168.1.1 (or whatever you changed your router IP to) and log into the webUI
  2. Go to Administration -> Firmware Upgrade click "Browse" and select file you downloaded and click "Upgrade"
  3. Wait a minimum of 5 minutes for router to reboot.
    Note: selecting "reset to defaults" on the drop down menu when flashing may soft brick your router which will require a power cycle.
  4. (Optional, but sometimes necessary) Perform a hard reset
  5. Navigate back to 192.168.1.1 and you should be greeted by the DD-WRT webUI
    Note: If you performed a reset, you will have to create a new password to login

[edit] Reverting back to stock firmware

  1. Download the latest E2000 firmware from Linksys site
  2. Navigate to 192.168.1.1 (or whatever you changed your router IP to) and log into the webUI
  3. Go to Administration -> Factory Defaults and select "Yes" and click "Apply Settings" and wait for router to reboot and return to the webUI (you will be prompted to set a new pasword; you can use "admin" temporarily for this.
  4. Login and go to Administration -> Firmware Upgrade click "Browse" and select the stock firmware file and click "Upgrade" and wait for router to reboot.
    Note: selecting "reset to defaults" on the drop down menu when flashing may soft brick your router which will require a power cycle.
  5. Perform a hard reset
  6. Navigate back to 192.168.1.1 and you should be greeted by the stock firmware webUI.
