yes, Mega is 8 mb and Big is 21 mb and your router has 32 megabytes of flash space to contain it. Once you have DD-WRT on the router, you can flash up and down build numbers. if you brink the router, you can easily recover back to stock using the ASUS recovery utility(it;s just a tftp utility)

and the answer to your next next next question is yes you can revert from 3.x back to down 2.6 kernel firmware without issue as well. just going from 2.6 to 3.x requires an additional step on this router.

Thanks to madman999 and others in the thread, I was able to get the latest build (r24461, 3.x kernel) onto my Asus RT-N16.

Background: I had originally used r19342 years ago but have been using r22118 for at least a year (both 2.6 kernel). It was mostly stable but I suspected it was the cause of some oddities (and I never trusted the WiFi). Regardless, I wanted 64K NVRAM so I can give OpenVPN a try again.

I tried going directly from r22118 to r24461 but that didn't seem to work, so I unbricked using Asus's recovery utility (TFTP app) to flash r21530 (3.x kernel) - worked great (requires holding the 'Restore' button on the router for a few seconds first). I was then able to update to r24461 and it's running stable now (64K NVRAM - yeah!).

I will try to remember to post a follow up if I end up trying to get OpenVPN running again.

Thanks to this thread, it was surprisingly painless getting r24461 installed on my Asus RT-N16

I flashed my Asus RT-N16 by using the download from the router database (yeah, oops) and then followed the wiki page. I didn't realize anything was out of date until I saw that I was running build 14896 from August 2010.

I saw that I was on a 2.6 kernel, so I decided to try a factory reset followed by upgrading to r21530. It worked perfectly. Then, just as thracx did, I flashed to r24461 without any issues.

I ended up with a couple of questions/concerns:

1. I was confused by the link to http://members.ziggo.nl/slobodan/. Is one of those binaries a more recent version than r24461. I apologize, because I am sure this is very obvious to you guys. I am just not understanding for some reason. :/

2. Has anyone had any luck figuring out how to upgrade the web server's ciphers to stop using ssl v3? Especially since the Chrome 39 update, the one that now blocks sslv3 post-poodle, went out recently. For anyone trying to search for this, the ssl error that Chrome surfaces is "ERR_SSL_FALLBACK_BEYOND_MINIMUM_VERSION". I happened to close chrome to let it update right in the middle of reflashing my router. doh. I was able to regain access to my dashboard by resetting my router and re-enabling http protocol under web access. But, ultimately, I would prefer to get the cipher suite updated and continue to serve over ssl. I found one post[1] about this, but I think their take away solution was to postpone upgrading their browser.

Anyways, thanks for all of the help!

That Ziggo website is a backup URL for Kong's build 22000++.

Thanks to this thread I have had v24-22118_NEWD-2_K3.x-big-RT-N16 running on my Asus RT-N16 since Nov. 2013, just over a year now. I also have a WD 3TB USB2 drive formatted to Ext4 for about the same time period. Everything works great, life is grand.

But I did notice a problem, no not really a problem, just an oddity that others here have also mentioned. My LAN and Wireless MACs are the same after the K3 22118 upgrade. Its been this way for a year now with no problems. However I'd like to fix this before I update to K3 24461, so I have some questions regarding MAC address.

1.) Is the MAC address printed on the label on the bottom of the router a WAN or LAM MAC address? I'm thinking WAN?
2.) My understanding is the MAC address for LAN, WAN and Wireless are sequential. But what order?
3.) The command to set the WAN address is "nvram set wl0_hwaddr=xx:xx:xx:xx:xx:xx && nvram commit". What are the variable names for LAN and Wireless address?

label on bottom of router shows xx:xx:xx:xx:xx:48

DD_WRT tab Status, subtab Router shows, MAC address xx:xx:xx:xx:xx:49

DD_WRT tab Status, subtab Sys-Info shows, LAN MAC address xx:xx:xx:xx:xx:4A
DD_WRT tab Status, subtab Sys-Info shows, WAN MAC address xx:xx:xx:xx:xx:49
DD_WRT tab Status, subtab Sys-Info shows, Wireless MAC address xx:xx:xx:xx:xx:4A

New topic:
After I get the MAC address fixed I plan on updating to K3 24461. I'm trying to decide between Big that uses 21 MB of NVRAM and Mega that uses 8 MB. Big has NTFS support and Mega doesn't. Mega has VPNC and Big doesn't. I'll never use VPNC and will "probably" never use NTFS. So my thinking is to install Mega so to have more unused NVRAM remaining in case I want to try to use OpenVPN. Anyone want to chime in with recommendations or insights?

Thanks for all the support.

thought this would be useful to be contained in this thread for those interested in going to the 3.x kernel version on this model.

We seem to have an issue where going directly to the latest version from a 2.6 version causes a brick. so the prerequisite step is to flash 3.x 21530 even though it;s not usable.

This guy seemed to have wrote it the best. Thanks again.

Based on previous notes from Mazout360 and madman999 this is how I got the latest K3.x image installed and working on my ASUS RT-N16

1/ Install and configure the latest version of K2.x
For example,
ftp://ftp.dd-wrt.com/others/eko/BrainSlayer-V24-preSP2/2013/07-24-2013-r22118/broadcom_K26/dd-wrt.v24-22118_NEWD-2_K2.6_big.bin

2/ Install dd-wrt.v24-21530_NEWD-2_K3.x_big.bin
This image can be downloaded from the first note in http://www.dd-wrt.com/phpBB2/viewtopic.php?t=86437&postdays=0&postorder=asc&start=1487.

3/ Upgrade to the latest version of dd-wrt K3 using the .trx file. I did NOT select reset to factory defaults. Currently the latest version is dd-wrt.v24-22118_NEWD-2_K3.x-big-RT-N16.trx
This image can be downloaded from
ftp://ftp.dd-wrt.com/others/eko/BrainSlayer-V24-preSP2/2013/07-24-2013-r22118/broadcom_K3X/dd-wrt.v24-22118_NEWD-2_K3.x-big-RT-N16.trx

Everything seems to working fine except that the LAN and Wireless MAC address were the same. I was not able to fix this from the Setup, MAC Address Clone GUI. To fix this I added the following line to Administration, Commands, Save Startup.
nvram set wl0_hwaddr=xx:xx:xx:xx:xx:xx && nvram commit
Substitute xx:xx:xx:xx:xx:xx with the LAN MAC address + 2. The LAN MAC address can be seen from the Status, Sys-Info page.

Everything seems to work fine. Note that I have not tested PPPoE.

Hello Everyone

I am currently using easy tomato firmware for my Asus RT-N16 router. I wanted to come back and try out dd-wrt as I haven't used it in years and even then it was a 2010 version that didnt work out for me on the router i was using back then.

Anyway, I was going to follow these directions to to install the latest version of the firmware but the last link (below) does not work, is it already outdated? Also, the original build list on the website says to pre install "dd-wrt.v24-14896_NEWD-2_K2.6_mini_RT-N16" is this really needed or can i go right to what is quoted above? I just want to get the latest working version installed.

After going through this summary topic, here is what I did to install DD-WRT on a stock RT-N16:

1. Flashed dd-wrt.v24-14929_NEWD-2_K2.6_mini_RT-N16.trx as suggested in the DD-WRT Wiki via Asus GUI.
2. Restarted while holding down WPS button for 30 secs.
3. Flashed dd-wrt.v24-21530_NEWD-2_K3.x_big.bin (5/10/13 build)
4. Restarted while holding down WPS button for 30 secs.
5. Flashed 24461_NEWD-2_K3.x_mega-RT-N16.trx (6/25/14 build)
6. Restarted while holding down WPS button for 30 secs.
7. Done!

So far so good. Everything seems to work, including Open VPN client, which is what I was after.

Been running tomato very happily for over a year. Rock solid. I have a 100Mbps service from my provider and have no trouble streaming full speed to the wired ethernet ports (usually over 90Mbps).

Needed VPN and thought I'd try dd-wrt.

First I tried the wiki's suggestion: dd-wrt.v24-18024_NEWD-2_K2.6_mega.bin
It all looked great... but then I did a speed test and it was horrible. About 50Mbps.

So then I figured I'd try a more recent build as suggested above: 24461_NEWD-2_K3.x_mega-RT-N16.trx
Again, all looked great. Performance was somewhat improved, but still stuck: about 65 Mbps.

So I went back to tomato and found their old VPN build:
tomato-K26USB-1.28.9054MIPSR2-beta-vpn3.6.trx

And lo and behold I was back to 90+ Mbps on the wired ports. And over 70Mbps over the wifi!

So heads up, the function may be good on dd-wrt, but be sure to test your throughput.

Am I the only one whose speed is only 54Mbps with both kingkong and brainslayer firmwares?

update: flashed K3 25697. Problem solved

So a little testing, 19342 was what I had originally installed earlier this afternoon after receiving the router, opted to try 15943 per this recommendation, difference between the two via speedtest.net testing over wifi @ two distances...

15943 = 10.93mbps download 10.13mbps upload

19342 (same settings) = 48.53mbps download 10.84mbps upload

Needless to say i'm sticking with 19342. File transmission rates via the LAN still suck however, getting about 7.5megs per second trying to transfer movies and such from my wired desktop to my laptop.

Could anyone tell me where I can download K3 r21530 for RT-N16? I'm cross eyed looking for it.
