Flashing DD-WRT
You will first need to download this file for the flashing.

ftp://ftp.dd-wrt.com/others/eko/BrainSlayer-V24-preSP2/2011/02-17-11-r16214/linksys_E2100L/e2100l-firmware.bin


 * 1) Go into the linksys stock firmware and choose to reset to defaults.
 * 2) Once that is finished, set a static ip on your machine to 192.168.1.7 with subnet 255.255.255.0 and gateway 192.168.1.1
 * 3) Log back into the linksys firmware and find where to update the firmware.
 * 4) Select the file linked above and then begin the flash procedure, this usually takes 6–7 minutes for it to finish properly, so be patient!
 * 5) Once it is finished, close your browser, then reopen and browse to http://192.168.1.1 it should want you to set a user/password, do so.
 * 6) When you are in dd-wrt's webgui, go to Administration > Factory Defaults
 * 7) Select to "Restore Factory Defaults" This will effectively hard reset the router and ensure integrity of the flash.
 * 8) Log back into the webgui @ http://192.168.1.1 and set a user/pass and enjoy dd-wrt!


 * Should you want to use DHCP you then may want to unset the static ip from your machine.

Reverting to OEM Firmware from DD-WRT
Should you want to revert back to stock firmware then you should be able to download the stock firmware from Linksys' site and flash back using the webgui.
