[edit] Installation

 **NOTE**: For firmware download locations Where do I download firmware?
 **NOTE**: Firmware images will be located in the broadcom_K26 or broadcom_K3X folder.

  • Trailed builds have e3200 in the filename.
  • SEE this post regarding the newer NV60K.bin files for some Linksys E-series routers
  • Do not confuse this with other E-series routers that must use only the NV64K builds
  • Support for this unit was added in build 17041, so do not use an older build or you will brick your unit!
  • READ the Peacock Announcement Carefully!

[edit] Procedure

  1. Disconnect all cables and wireless clients.
  2. Perform a 30/30/30 reset to the E3200.
  3. Download E3200 Trailed Initial Flash Build.
  4. Connect PC via ethernet cable to a LAN port
  5. Open a web browser and navigate to http://192.168.1.1
  6. Login with the default credentials (admin/admin)
  7. Click on Administration.
  8. Click on Firmware Upgrade.
  9. Click on the Choose File button and select the previously downloaded dd-wrt.v24-19342_NEWD-2_K2.6_mini-e3200.bin file.
    • Click Open.
  10. Click on the Start Upgrade button

    11.  **CAUTION**: After you start the firmware update, do not try to go online, turn off the router, close your browser, interrupt the process, or do anything else to the router until it finishes restarting.

  11. Wait 10 minutes until the WLAN (wireless) light turns on.
  12. Power cycle the E3200 by unplugging it for 10 seconds.
  13. Plug the E3200 back in and wait about 5 minutes until it finishes booting.
  14. Perform a 30/30/30 reset to the E3200.
  15. Wait 3 minutes then browse to http://192.168.1.1
    • You should be greeted by the DD-WRT WebUI
  16. Enter new password (the second and third box) and click Change Password.
    • You will be taken to the Info Page.
  17. Click on Setup and begin configuring as desired, clicking Save on each page as you go
  18. When you are finished, click on Reboot Router on the Services or Administration tab.

[edit] Upgrading or Downgrading DD-WRT

  • To flash other builds when running DD-WRT, only use the nv60k.bin (or trailed e3200.bin) files.
    • K3X builds do not have a nv60k.bin file, use the generic mega.bin file.
  • Only use nv60k builds 17041 or greater.
  • This router works with the Mega build 33555, but KRACK fixes for Broadcom were completed in 33678, including k26 (33655) & k24 (33656), but build 33679 is missing many files. Thus, use 33772 (or newer).
  • If a K3X reset breaks wireless, flash the same build number K26, reset, then flash back to K3X without reset.

[edit] Procedure

  1. Download the most recent K2.6_big-nv60k.bin, K2.6_mega-nv60k.bin, K2.6_mini-nv60k.bin, K2.6_mini-e3000.bin, K3.x_mega.bin, or K3.x_mega-e3200.bin from the broadcom_K26 or broadcom_K3X folder as applicable.
  2. Open a browser and go to http://192.168.1.1 (or whatever IP address you changed your router configuration to)
    • Login using proper credentials; Default username is root.
  3. Navigate to Administration -> Firmware Upgrade
    • Leave "Do Not Reset" selected for After Flashing.
  4. Click on Choose File and select previously downloaded K2.6_big-nv60k.bin, K2.6_mega-nv60k.bin, K2.6_mini-nv60k.bin, K2.6_mini-e3000.bin, K3.x_mega.bin, or K3.x_mega-e3200.bin as applicable.
  5. Click Upgrade
    • Your router will start updating the firmware.

     **CAUTION**:  After you start the firmware update, do not try to go online, turn off or do anything else to the router, or close the browser window until it finishes restarting.

  6. You should be able to click Continue button and be greeted by the Setup page; if you get a Cannot Connect warning page in your browser, just browse to http://192.168.1.1 or whatever the router IP address is.

[edit] Reverting to stock firmware

  1. Download FW_E3200_1.0.05.002_US_20140516_code.bin
  2. Reset the router back to defaults using a 30-30-30 hard reset
  3. Flash the stock image from the DD-WRT GUI using the upgrade procedure above.
    • Wait at least 5 minutes for it to finish
  4. Reset again
  5. Access the Linksys GUI @192.168.1.1.

[edit] Recovery

Recovery can usually be accomplished by TFTP flash. Worst Case scenario requires Serial Recovery

[edit] Tx power rating

The E3200 has an internal amplifier for each radio. You can use some of these figures to come up with what Tx power rating would be best for you. As factory lists it a max of 20dBm then a setting of 100mW could be used as 20dBm = 100mW 17dBm = 50mW and so on.

[edit] 2.4GHz Tx power per chain

  • 802.11b: Max. 20.5dBm @ All rates
  • 802.11g: Max. 19.5dBm @ High rates
    • Max. 20.5dBm @ Low rates
  • Wireless-N 20MHz: Max. 18.5dBm @ High rates
    • Max. 20.5dBm @ Low rates
    • Wireless-N 40MHz: Max. 17.0dBm @ All rates

[edit] 5GHz Tx power per chain

  • UNII-1 (5150-5250GHz)
    • 802.11a: Max. 14.0dBm @ All rates
    • Wireless-N 20MHz: Max. 11.5dBm @ All rates
    • Wireless-N 40MHz: Max. 12.0dBm @ All rates
  • UNII-3 (5725-5850GHz)
    • 802.11a: Max. 17.5dBm @ High rates
      • 802.11a: Max. 20.0dBm @ Low rates
    • Wireless-N 20MHz: Max. 17.5dBm @ High rates
      • Wireless-N 20MHz: Max. 20.0dBm @ Low rates
    • Wireless-N 40MHz: Max. 17.5dBm @ High rates
      • Wireless-N 40MHz: Max. 21.0dBm @ Low rates

Internal PIFA antennas are rated at 3dBi
