Posted: Wed May 20, 2015 6:31 Post subject: ASUS RT-N12+ Hi I hope I am in the Right forum. I asume that the RT-N12+ have a broadcom chipset, but I am not sure. I have not been able to find anything on this model. There is not any FCC-ID printed on the device. Could you suggest a dd-wrt build that I could try to install on the device. Press Reset button for at least 6 seconds; Restart of the device is automatically executed; Default settings have been restored; Execute software reset. With the ASUS RT-N12 D1, you can restore the factory settings with the installed software. Reset your RP-N12, double check your router SSID/password, and set up RP-N12 again. Q4: How do I reset RP-N12? A4: Using a pin, press the RESET button for about two (2) seconds. Wait for about five (5) seconds until the Wi-Fi LED flashs red. Method One Reset Your RP-N12’s wireless network name (SSID) changes.

I've compiled your magical procedure into the wiki, take a look:
https://dd-wrt.com/wiki/index.php/Asus_RT-N12#RT-N12D1_Installation

Looks good to me.
Glad you specified the builds to use for the D1. So many people will grab the C1 or B1 firmware cause it seems a close fit --- that is not the way.
In all the different builds I have used on the RT-N12D1 I have never used a build made for C1 or B1.
When time permits I'll drag mine out and try some newer builds ... see what happens.
As for my opinion with newest builds as of this time on the Rt-N12D1, I'd say 50/50 chance you may lose your router or put it in a bricklike-doorstop-state.

FWIW, the 33215 mega wouldn't play for my D1 (using 'updated' D1 install instructions) - but v30-29409 mini did, just my $0.02.

Interesting; you went from stock to dd-wrt.v24-25974_NEWD-2_K2.6_mini.bin to dd-wrt.v24-33215_NEWD-2_K3.x_mega.bin but the latter failed? And you followed the wiki's (meaning mrjcd's...) exact steps (such as, no resets except in OEM f/w, and flashing 25974 twice)?

yes, I suspect it's because some D1's may only have 4MB of NVRAM like the C1 so the megas will fail

You mean flash (ROM); the C1 has 8MB. OEM firmware is bigger than 4MB:
    Version 3.0.0.4.376.3754
    2015/01/12
    5.76 MB
OEM D1 firmware is even bigger:
    Version 3.0.0.4.380.8120
    2017/11/01
    6.91 MBytes
What does dmesg show for flash size?

I also tried the upgrade in the wiki to the 'dd-wrt.v24-33215_NEWD-2_K3.x_mega.bin' build. But after flash the wireless light wasn't lit. Then after a while refreshing pages started missing packets. Then eventually the whole GUI was unresponsive even though pings went through.
I downgraded back to 'dd-wrt.v24-25974_NEWD-2_K2.6_mini.bin' and it seems to be okay.
UPDATE: Maybe some of the packet loss was due to my browser/ad blockers. I've upgraded to 'dd-wrt.v24-35244_NEWD-2_K2.6_mega.bin' and was still getting a bit of packet loss (pages don't display properly) sometimes even though I'm hard wired. But I've successfully setup my wireless Client Bridge and I'm getting about 88Mbps from the living room.

I'm not really sure why the instructions are so convoluted. I started following them, I installed the .trx linked, but after it went to the endless reboot cycle I just went into rescue mode. You turn the router off, hold the reset button and keep it held down until your ping to 192.168.1.1 works. You'll notice the ttl=100. That means it's in rescue mode. I went to the web CFE page at http://192.168.1.1, picked the mini.bin in the zip file. After that uploaded and rebooted, I grabbed a firmware from the ftp site. I picked dd-wrt.v24-34311_NEWD-2_K3.x_mega.bin at random, uploaded it and picked the option to reset nvram as well. Booted and seems to work just fine.
I'm going to bet going into rescue mode and uploading the mini firmware would work just fine, then upgrade to a newer mega one. Just make sure to reset nvram. This build has 256k of nvram it seems.

What do you mean ports are unresponsive and wireless security doesn't clear? Make sure you clear nvram when you update…

So, I think the Wiki (this page: https://www.dd-wrt.com/wiki/index.php/Asus_RT-N12) needs to be updated.
I had two RT-N12 ver D1's and I successfully updated them to dd-wrt using the 'old' instructions (prior to the update that I think occurred around March 22 2018.)
The 'old' instructions mentioned using ports 2 or 3 only, and using tftp to do the upload, and did not reference the ASUS recovery utility at all. Like I said, I had no trouble with these instructions.
Recently, I purchased a third RT-N12D1, and discovered the instructions had changed. I tried following the instructions as they appeared on April 11, 2018, and found they did not work.
When I attempted to upload the .trx file (step 4) I got an error saying that the firmware was not certified or something (sorry, I didn't capture the full error message.) The progress bar went to 100%, but at the end, nothing happened. The router did not reboot, and even when I rebooted it manually, it came back up on the original firmware. I also tried finding the original firmware version mentioned in the instructions (3.0.0.4.374.813) and tried uploading that through the web UI, but I got the same error message, and the firmware did not update.
I can't remember the exact firmware version the router came with, but I think it started with 3.0.0.4.380.xxx
What I wound up doing is putting the router into recovery mode (holding the reset button for 15-20 seconds while powering on the router) and then using the ASUS recovery program to downgrade the firmware to version 3.0.0.4.374.813. Once this was complete and the router rebooted, I was able to follow the instructions in the wiki and everything worked.
So, it seems ASUS has added some sort of firmware signing feature to newer firmware versions that will not let you either downgrade the firmware past a certain version, or load 3rd party firmware via the web UI.
Downgrading the firmware using the recovery utility seems to work around the issue.
Hope this helps.

This is the case with many (most? all?) manufacturers for (at least) US models, due to FCC mandates.
Did you try the 'old' method when it still had the original (newer) OEM f/w?

Not on the latest router, because those instructions are no longer on wiki, and I could not remember the sequence in sufficient detail to want to risk it. I suspect it would have worked fine, since the initial load of dd-wrt was uploaded via tftp, likely by-passing any sort of firmware signature check. I didn't bother to check what version of the firmware was running on the first two routers I updated with the tftp method, though it wasn't that long ago -- maybe February 2018?
If anyone has an older copy of the update instructions for the RT-12ND1, or if the wiki saves revisions and that's something that could be retrieved, it might be a good idea to list the previous method as an alternate way to install dd-wrt on these routers with the newest firmware.

Yesterday I forgot my router’s password. So I thought to reset the device. I tried to follow the instructions present in the manual as well as on the web but the reset button seemed to be not responding.

The instructions given in the web are mostly wrong and totally misguiding. I followed those and repeatedly failed.

Here are the steps to follow:

1.Unplug all the Ethernet cables.

2.Make sure the router’s power is on.

3.Locate the small reset button present at the back.

4.Press the reset button till all the green lights start blinking.

5.Now connect all the Ethernet cables.

6.Visit 192.168.1.1 to put all the necessary IP address values and configure the router accordingly.
