For the rt-n66 just use the k3.x-big-rtn66 file. That's all you need.

Hi!

I buy the N66U with the HW Version B1.
I tried to flash the dd-wrt Firmware from the database " dd-wrt.v24-24461_NEWD-2_K2.6_mini_RT-N66U.trx"

I only can see the "Settings have been updated. Web page will now refresh. Changes have been made to the IP address or port number. you will now be disconnected from RT-N66u. To access the settings of RT-N66U, reconnect to the wireless network and use the updated IP address and port number."
ping works during the message

Only the power LED flash every 4 seconds for 4 seconds.

I tried the Merlin 380.62 Version to flash. Its the same. I wait 30 minutes to restart the router, but it still dont works.
I tried this tutorial http://mikebaas.org/writings/Technology/Computers/asus_nt-n66u but its the same
any ideas? Sad

Did you read any of this thread before you flashed that build?

With the latest versions of DD-WRT, is there any degradation of WiFi or LAN performance (particularly 5Ghz band) when compared to Asus' firmware? If so, does Merlin firmware have the same performance as Asus'?

S'OK, doing the rescue mode thing seems to have done the trick, though it was a fight to get into rescue mode. For the record, my successful procedure was:

1. With the router not connected to anything other than power, hold the reset button and switch the router on.
2. Wait for the power LED to flash (really slowly) and then release the reset button.
3. Connect a LAN Ethernet port to a PC where the PC's Ethernet port's TCP/IPV4 network properties have been assigned a manual IP address of 192.168.1.12 and a gateway of 192.168.1.1.
4. Start Chrome.
5. Go to chrome://appcache-internals/ and remove any entries for 192.168.1.1 or asus.
6. Browse to 192.168.1.1. You may have to wait some time for Windows to sort out what kind of network connection this is.
7. Eventually you should get an Asus mini-CFE web page which allows you to reset NVRAM and upload a new image.
8. Reset NVRAM.
9. Upload a "big" DD-WRT image, e.g. dd-wrt.v24-30949_NEWD-2_K3.x-big-RT-N66U.trx
10. Wait for it to upload and then for the wireless networking lights on the router to come on. This may take many minutes.
11. Press "continue" on the browser screen and you should see a DD-WRT screen.



I am having troubles with my router and this procedure. I get as far as uploading the DD-wrt image cited above. As it uploads eventually the web page goes dead and safari says it can't open the page. I then wait for an hour. I switch back to DHCP for my plugged in connection and it says it is a self assigned IP. The wireless lights never come on. What should I do at this point? Do I have to try resetting using the WDS for 10 seconds when I turn it on, do a 30-30-30 with the WDS or something else? I've tried version 26138-big, 26138-mega, 29134-big, 29134-mega as well without success, although my exact procedure may have varied slightly after i uploaded the image.

Thanks!

Don't use any other firmware than the one with the router name in it like this ftp://ftp.dd-wrt.com/betas/2017/02-07-2017-r31277/broadcom_K3X/dd-wrt.v24-31277_NEWD-2_K3.x-big-RT-N66U.trx

Of course, if you've flashed newer asus firmware you are locked out due to the FCC. You'll have to use the firmware restoration utility to flash an older version of asus firmware then dd-wrt.

Hi, i'm have n66u (i'm think is rev. B1) on last version stock firmware, what i'm need to doo to flash dd-wrt!?

What version of old stock firmware need to flash before flash dd-wrt?
What version ASUS Restoration utility i need ver. 2.0.0.0?

Can i'm use this version of dd-wrt ftp://ftp.dd-wrt.com/betas/2017/03-04-2017-r31571/broadcom_K3X/dd-wrt.v24-31571_NEWD-2_K3.x-big-RT-N66U.trx after downgrade asus firmware?

Use this instruction?
1. With the router not connected to anything other than power, hold the reset button and switch the router on.
2. Wait for the power LED to flash (really slowly) and then release the reset button.
3. Connect a LAN Ethernet port to a PC where the PC's Ethernet port's TCP/IPV4 network properties have been assigned a manual IP address of 192.168.1.12 and a gateway of 192.168.1.1.
4. Start Chrome.
5. Go to chrome://appcache-internals/ and remove any entries for 192.168.1.1 or asus.
6. Browse to 192.168.1.1. You may have to wait some time for Windows to sort out what kind of network connection this is.
7. Eventually you should get an Asus mini-CFE web page which allows you to reset NVRAM and upload a new image.
8. Reset NVRAM.
9. Upload a "big" DD-WRT image, e.g. dd-wrt.v24-30949_NEWD-2_K3.x-big-RT-N66U.trx
10. Wait for it to upload and then for the wireless networking lights on the router to come on. This may take many minutes.
11. Press "continue" on the browser screen and you should see a DD-WRT screen.

Or use ASUS Recovery utility to flash dd-wrt after downgrade asus firmware?

Or downgrade asuswrt to old version via ASUS Recofery utility and flash via stock ASUS Firmware GUI dd-wrt firmware?

Help, i'm confused Very Happy

Flash an older version of stock or rmerlin firmware released before the FCC rules, it will tell you on the asus download page which that is, using the asus firmware restoration tool, then you whichever k3.x firmware for the rt-n66u that you want to use.

I want to flash dd-wrt k3 build on RT-N66U. But I need firmware with support for SWAP in the kernel. Is there such firmware for this router?

Hi, i'm do what you say, downgrade asuswrt to http://dlcdnet.asus.com/pub/ASUS/wireless/RT-N66U_B1/FW_RT_N66U_30043762524.zip, then via asus recovery utility flash last betta dd-wrt to my RT-N66U, flash is ok, but when i'm change wan and wifi setting, pppoe wan is not connect, and some problem whith wifi, 5G wifi led is not work, then i'm again back to last stock asuswrt.

What i'm need to do, check the CFE version? Problem in my CFE?

The problem is probably not the cfe but your setup.
You don't need to use the recovery utility to flash dd-wrt. You can just flash it from the asus firmware.

When i'm flash dd-wrt on AC88U bl_version 3.0.0.0 via asus recovery utility have the same problem, i'm need flash dd-wrt from the asus firmware gui too?

Yes, just flash from the GUI but if you install the latest asus firmware on the rt-n66u then you have to use the utility because of checks put into the firmware to prevent third party firmware flashing.
As to the rt-ac88u, you may not be able to put dd-wet on it at all.
A lot of people on the forum are finding it won't accept any third part firmware.

Today upgrade RT-N66U from RT-N66U_3.0.0.4_376_2524-g0013f52 asuswrt gui and have the same problems, wps button 30/30/30 not work, wan not up, wifi not tested today, reset button work.

strings /dev/mtd0ro | grep bl_ver
bl_version 1.0.1.2

Update CFE via instruction and then again try to flash dd-wrt last beta?

Have idea, what's wrong?
