    Hello all...

    Could someone please point me in the right direction. I have just bought a N66 and looking to flash shibby firmware. (Or what would you say is the best firmware out there).

    What steps and process do I need to take?
    Link to the latest firmware? I noticed from this page that latest firmware should be few days ago:

    Just that you know, this is my first time of looking to flash a custom firmware on a router..

    Hello mate.

    Dead easy, I flashed Tomato Firmware v1.28.0500 MIPSR2Toastman-RT-N K26 USB VLAN-VPN I do like "Toastman" builds but each to there own.

    this is the version I used. tomato-K26USB-NVRAM64K-1.28.0500.5MIPSR2Toastman-RT-N-VLAN-VPN as that is for the 64 k ram versions which if you have a read back then you'll see it tells you how to check.

    Flashing is dead easy, you hold the WPS button down and then plug it in and keep it pressed down then the power light will start flashing, this has then put the router into recovery menu, change your network adaptor to have a static ip address of say and then plug it into your laptop/pc.

    Then run the recovery option and then loads the CFW (Follow the tut for the exact procedure) and then when it finishes, re-boot, it does tell you that it didn't flash but that's because the recovery utility isn't built for CFW builds. then when it's rebooting clear the nvram, as described in the tut.

    Other than that, then once you have a build on then it opens the router right up, just make sure you want to as you will loose some of the rl= but gain a lot.

    Thanks a million mate. Do I need a putty session or an ssh, telnet or remote login to connect to the router? Or I do I connect to the router to check the version if it 64k ram or not.

    I used the reset button at boot up.

    Because the 60K build seems to flash OK, I think if someone encounters a problem its safe to go to the 60K build, long erase the NVRAM, then upgrade to the 64K build through the Tomato upgrade function, followed by long erasing the NVRAM. Treat the 60K as an interim step for problem routers.

    I actually chickened out on that first router and left the 60K firmware on it, but need to swap it out for a unit with the 64K build on it at some point. For now its working, and has over 50% of NVRAM free, so... its not my highest priority. The ones I've done since are 64K and are working fine.

    So I still don't know if it's safe to flash 60K toastman firmware (tomato-K26USB-NVRAM60K-1.28.0501.2MIPSR2Toastman-RT-N-Ext.trx) on my RT-N66U? I've been told that if this is done incorrectly, it will completely destroy the router. Right now, my router shows that it only has 32k of NVRAM. Does the code in the new version have the necessary hack to address more than 32k. Should I try to flash 60K and then flash 64k?

    My CFE is: bl_version=

    this image is INCORRECT to use with RT-N66u. It will works as 32k build. When you will try save more than 32KB datas in NVRAM then router will BRICK!

    Just received a new RT-N66U from Amazon. I installed tomato-K26USB-NVRAM64K-1.28.0501.2MIPSR2Toastman-RT-N-VPN on it out of the box using the Asus firmware upgrade utility. It works fine. The CFE version is It shows I have exactly 65536 kb of NVRAM. Everything seems to be working fine.

    Then how do I access the full 64k of NVRAM like the new ASUS firmware (that I've never installed, it was released after I flashed a 32k build of Toastman's?)

    Hi, I'm also currently running an E3000 and thinking to upgrade, the RT-N66U being a possibility. Could you clarify (and quantify?) in what aspects it is better than E3000? My internet isn't crazy-fast - 10MB - so WAN isn't so much of an issue. But I use 5GHz wifi a lot for LAN transfers and backup, so 5Ghz wifi range and speed is important to me. The other reason to upgrade is I want to run Shibby AIO builds and the 8MB flash of the E3000 is proving limiting. Thanks.

    From E3000 to N66U yes it's amazing but E4200v1 is a good machine as well.

    I switched to an RT-N66u when my E3000 died. I honestly don't notice much, if any, difference. For a small home connection, I don't think there is a difference.

    Simple. Use a 64K RT-N USB build.

    If you encounter problems I would put it in recovery mode, and then from the recovery website (assign a fixed IP - e.g. - to your NIC, then visit perform an NVRAM erase, then issue a reboot from that website. It should allow the system to boot (though the first boot may take a long time, it may even seem to boot and reset once), after which you should perform a long NVRAM erase from within Tomato.

    The N66U can handle a 50Mb line with numerous L7 filter rules in QoS. If you aren't pushing that kind of speed or using L7 filtering, I don't think it'd be all that different (aside from 5Ghz support) from a RT-N16 - which (I think) is substantially slower than an E3000.

    In my experience the N16 can get into the high 40Mb range without L7 rules and 50Mb or damn close to it without any QoS at all, but L7 filters are too CPU intensive for it to both push that much data and filter. You can push >50Mb through an N16 but you have to strip its config down to nothing (and be running over Ethernet) - no iptables rules beyond blanket "ALLOW", no NAT translation, nothing but routing between two networks.

    The N66 allows you to just set it up, turn everything on, and voila... it works at full speed.

    That's what I asked about, tomato-K26USB-NVRAM64K-1.28.0501.2MIPSR2Toastman-RT-N-Ext.trx

    Then I was told by shibby20 that this was incorrect and would brick my router. I'm asking this question because NO one can seem to agree on if this is okay or not.

    You need to have a '64k aware' CFE to use that. If you are interested in updating your CFE then go here http://forums.smallnetbuilder.com/showthread.php?t=8259 and follow the instructions to upgrade. After you do, you can't use 32K firmwares anymore. Actually some firmwares can handle both situations but I would just stick to 64K firmware after the upgrade.

    From the context of what shibby just said in this thread, it isn't clear whether he's referring to the 60K firmware, the 64K firmware, or both.

    I assumed he was talking about a 60K build only working as a 32K flash until it bricks but it could very well be the reverse.

    We lost a couple weeks worth of conversation from when I was off on vacation/winter break so I have no idea if some lost conversation covered this topic more thoroughly.
