E2000 Hardware Specs


CPU Broadcom BCM4717A
CPU Speed 354 MHz
Flash ROM 8 MB
Radio 1x 2.4 GHz or 5 GHz selectable
WLAN Support a/b/g/n
WLAN Max Speed 300 mbps
Antenna Location Internal
Switch 4x GigE + 1 Gbit WAN

Flashing instructions for the E2000

1) Disconnect all cables and wireless clients.

2) Do a 30/30/30 reset on router

3) Connect 1 Lan cable to pc doing the flash.

4) Log into Web Interface and flash the firmware 14929 E2000 Trailed Initial Flash Build

5) Wait 5 minutes until WAN light turns on.

6) Power cycle by unplugging E2000 for 30 secs.

7) Plug E2000 back in and wait about 5 minutes until it finishes booting.

8 ) Do a 30/30/30 reset on router.

9) 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 use the e2k-e3k.bin's for upgrading to newer builds.

DD-WRT E2000 Build information

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

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

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, you can simply use one of those 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

  • 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


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

VLANs Support

It is also known for the E2000 to support VLANs. Please refer to these links for further info.

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.
