I have installed DD-WRT on a number of devices without issue. I needed a new router and wanted something reasonably powerful and cheap.
Well I bought an RT-12N.B1. I have followed the flashing instructions. I tried recovery method and 30/30/30. After I flash, the router just boot loops constantly rebooting. I can flash back to stock and it works fine.
I tried clearing settings etc but I did notice, after I reflashed back to stock and all of my prior settings were there and no restore was required.
This tells me that maybe the fact that the NVRAM was not cleared was causing it to boot loop.
I have tried everything I can think of to reset the NVRAM and it is always still there persistently bugging the crap out of me.
So two questions:
1) Am I correct in assuming the uncleared NVRAM is most likely causing the boot loop?
2) Anyone know the magical secret to clearing the NVRAM on this thing for flashing?
Reset to default won't work because it is technically not clearing the NVRAM just changing the settings.
I am trying to do this because I bought a VPN tunnel and want to VPN my residence at the router level. Unfortunately, the ASUS stock firmware does not seem to support this.
Any help would be appreciated. I tried searching for the answers and there just were too many results to be useful. I read through two pages of threads and gave up.
Today I had 2 RT-N12 B1s brick in the exact same way, using the same dd-wrt files I've flashed dozens of these up with.
Something has to have changed with these RT-N12 routers that is causing it, the only difference I can think of is a newer version of the ASUS firmware that comes preinstalled on it (2.1.1.1.38).
I can get to the broadcom CFE mini webserver page, but because the router will constantly reboot itself every 10 seconds I cannot recover the firmware in any way.
Here the procedure for brik router who is rebooting :
1. In order to prevent DHCP from interupting the connection, you will need to manually set the address of your PC's Network LAN card to a STATIC IP in the same subnet of the router, such as 192.168.1.10 with subnet mask 255.255.255.0 . Also make sure all other adapters,such as wireless, which might be seen as "clients" by the router are disabled. Only the main LAN connection [IP: 192.168.1.10] should be able to communicate with the router.
2. Unplug the power connector from the back of the router.
3. While pushing & holding the recessed Restore button on the back of the router, plug the power connector back in. The Restore button is NOT the raised red WPS button.
4. When the power LED slowly blinks on and off, release the Restore button. The router is now in "RESCUE MODE".
5. Open the router IP of 192.168.1.1. The page will open to a built in browser (HTTP) recovery console.
6. Click on the link below Reboot to reset/flash the Vram.
7. Click the Browse button to browse to your DD-WRT firmware file location.
8. Click the Upload button.
The router will upload the file and show this message.
"Receive file size=3440689
Upload completed. System is going to reboot.
Please wait a few moments."
You will see the LAN1 light turn off and notice the "Network Cable Unplugged" windows popup message in task bar. Wait for the light to turn back on and the PC to reconnect to router.
9. Click the "Continue" link shown on the page.
Clicking "Continue" forces the router to perform another reboot. When it comes back up you will be at the DD-WRT admin login screen.
I am trying to get rflow on this RT-N12 and on the mini build we used for the initial flash, there's no rflow on it so I need to use at least the standard version.
So, if I've done my research correctly, we started by the mini build for the initial flash, but it is possible to flash a standard version since there's at least 4mb on this router. Am I right?
If so, can someone lead me to the correct generic standard build, I am not sure which one to choose and if it is the correct one (v24, sp1, pre-sp2, stable, generic, etc..) and then, this one (which must be a .bin since it is already flashed) can be simply uploaded via the dd-wrt web interface.
I know you guys must deal with a lot of newbies, but I tried my best to research until I reached this point where I have to choose a build and I can't figure out which one is the good one.

I've setup two of these routers using this firmware in the last month and both of them have had very poor wireless throughput (<1mbps) with N wireless enabled. As soon as I disable N I get perfect throughput with G.
Looking for some help here. I love this router but I'll have to switch to something else if this keeps happening. Is anyone else having this problem? Is seems like it must be a dd-wrt bug since it's happened to me twice in a row.
