Do NOT flash larger builds!


[edit] Flashing Instructions

WARNING: only use nv64k builds. Don't confuse this with other Linksys E-Series units use nv60k builds!

  • These instructions were performed with an e1200v2 running FW_E1200_v2.0.07.002_US_20150108.bin
  1. With a wired connection, log into the Linksys Web Interface Firmware Upgrade page.
  2. Do a reset using the stock web interface. Wait a minute.
  3. Flash the initial flash firmware: dd-wrt.v24-19519_NEWD-2_K2.6_mini-e1200v2.bin
  4. Wait 2 minutes for the router to flash and reboot itself.
  5. Wait about another 2 minutes until it finishes booting.
  6. Log into the dd-wrt web interface and set a password
  7. Flash the Upgrade build and then reset using the GUI
    • Wait 3-4 minutes for the flash to complete, then if isn't accessible, manually power cycle the router

For download links, build information, and more: Where do I download firmware?

Minimum build with the Broadcom krack fixes is 33772. See here for more info.

[edit] No LAN ports After Reset

There is a persistent bug with some E-series routers in DD-WRT after a reset, where the LAN-ethernet ports are not bound to anything, and only wireless (WLAN) is working initially.

Fix: access the web interface using wireless and add vlan1 (ethernet ports) back to the bridge.

  • For a step-by-step and more details see here.


[edit] Recovering from Management Recovery Mode

Follow the E1500 directions, substituting e1500 for e1200v2 and using the appropriate firmware.


[edit] Reverting to Stock Firmware

Download the stock firmware image from the manufacturer's website (link), reset the router back to defaults using a 30-30-30 hard reset, then flash the stock image from within the dd-wrt webgui. After 5 minutes it should finish, you will then need to do another 30-30-30 reset and then access the stock webgui @ 192.168.1.1
