Linksys E2000

The router has a single radio (i.e. not simultaneous dual-band).

E2000 serial numbers appear to start with CVR0.

"3763-20300103R" is silkscreened on the board in the FCC photos. The device is presumably identical to the Linksys WRT320N v1.

Flashing DD-WRT
'''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.'''

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.

Reverting to OEM Firmware from DD-WRT

 * 1) Go to Linksys support site and download the latest stock E2000 firmware image.
 * 2) From within the dd-wrt webgui go to Administration > Factory Defaults, and reset to factory defaults.
 * 3) Once you router has reset to factory defaults, set a static ip on your machine to 192.168.1.6 and access the webgui @ http://192.168.1.1
 * 4) It should prompt you to set a user/password, do so, then from the webgui, go to Administration > Firmware Upgrade
 * 5) Select to reset to defaults on the drop down menu and then browse to the stock firmware image for the E2000, select the file and flash.
 * 6) Wait 5 mins from flashing, then do a 30-30-30 reset and login again @ http://192.168.1.1 and begin your config on stock firmware.


 * Should you want to use DHCP you will need to then unset your static ip on your machine.
