Flashing instructions for the E2000

DON'T BRICK YOUR ROUTER! AFTER FLASHING WITH THE TRAILED BUILD, IF YOU THEN FLASH A BUILD THAT DOESN'T HAVE e2k-e3k in the NAME OF THE BUILD YOU ARE FLASHING YOU *WILL* BRICK YOUR e2000 ROUTER. ALSO reference this post regarding the newer NV60K.BINS FOR ALL E~ Series linksys http://www.dd-wrt.com/phpBB2/viewtopic.php?p=569485&highlight=#569485

  1. READ the Peacock Announcement Carefully! http://www.dd-wrt.com/phpBB2/viewtopic.php?t=51486
  2. Disconnect all cables and wireless clients.
  3. Do a 30/30/30 reset on router
  4. Connect 1 Lan cable to pc doing the flash.
  5. Log into Web Interface and flash the firmware 14929 E2000 Trailed Initial Flash Build
  6. Wait 10 minutes until WAN light turns on.
  7. Power cycle by unplugging E2000 for 30 secs.
  8. Plug E2000 back in and wait about 5 minutes until it finishes booting.
  9. Do a 30/30/30 reset on router.
  10. Wait 3 minutes and log into web interface.

As of July 2010 you can only use the trailed builds with the e2000 name in it for initial flashing and nothing else, using other bin's without the e2000 name in it for initial flashing may result in a bricked unit! After you have dd-wrt installed to your unit, you can then ONLY use the e2k-e3k.bin's for upgrading to newer builds. ALSO reference this post regarding the newer NV60K.BINS FOR ALL E~ Series linksys http://www.dd-wrt.com/phpBB2/viewtopic.php?p=569485&highlight=#569485

DD-WRT E2000 Build information

Recommended Build

The recommended version is 14929 as of 1/3/2011. (Reference Thread)


The latest builds for this unit can be currently found in the FTP. Support was added in 14826 and on.

Eko K2.6 NEWD-2 Builds

ftp://ftp.dd-wrt.com/others/eko/V24-K26/

Brainslayer added E2000 Support from 14929 and on and builds are to be found in the broadcom_K26 folder of his build branch.

ftp://ftp.dd-wrt.com/others/eko/BrainSlayer-V24-preSP2/

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. ALSO reference this post regarding the newer NV60K.BINS FOR ALL E~ Series linksys http://www.dd-wrt.com/phpBB2/viewtopic.php?p=569485&highlight=#569485

Some useful tips

  • 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:
Wireless > Channel > Ch 161 (5GhZ)
Wireless > Channel > Ch 9     (2.4GhZ)
Wireless > Security > WPA2 Personal - AES
Wireless > Advanced Wireless Settings > Beacon Interval: 75
Wireless > Advanced Wireless Settings > Fragmentation Threshold: 2306
Wireless > Advanced Wireless Settings > RTS Threshold: 2307
Security > Firewall > Block Anonymous WAN Access <--- Uncheck


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 commit
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.

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.
