Asus RT-N66U Router

[Apokalipse]

Ok. I just got down loading the latest official asus firmware on it and then did a telnet session and checked the CFE version and its 1.0.1.2.. I tried loading the dd-wrt.v24-18702_NEWD-2_K2.6_big_RT-N66U.trx on it and it worked, but when I tried saving settings on the routers homepage.. it would never save them on any page so I figured something got screwed up somewhere along the line... :/ Am I using the correct DD WRT version or should I be using something else?

1.0.1.2 means it has 32K NVRAM. In that case, I would upgrade the CFE.

This is probably a better DD-WRT build to use. Though I use TomatoUSB.
I think this build of DD-WRT works with either 32K or 64K NVRAM (older versions didn't).

This is the guide that I am trying to follow: DD-WRT on the Asus RT-N66U – with 64K CFE | Charles Wilkinson So I got the original asus firmware loaded and then loaded the Merlin firmware which worked just fine.. It said in the guide that you need to upgrade your CFE, which is explained here CFE bootloader update - SmallNetBuilder Forums . So currently, I have a SSH session open to the router and am trying to get the file on a remote server, but getting a 'wget bad address' and it doesn't connect to the site (see screenshot). Do you know how I would do a local copy into the router?? Someone said they had to use a SCP command. Thank you!

You can use winscp to transfer files to the router.
Or possibly enable Samba file sharing (which means you can just use windows explorer).

If you want to use wget to download anything, it needs to be connected to the internet (using the WAN port) and be able to resolve DNS.

Ok so I uploaded that DDWRT file and then rebooted and did the 30/30/30 and now when the router comes in, the power light blinks on and off like its auto booting in recovery mode or something?

If the firmware isn't working:

* Download a TFTP server program. The Asus Firmware Restoration Utility is essentially just that, and is easy to use.
* Download new firmware, and make sure it's designed for 64K NVRAM. I used TomatoUSB firmware (this is currently the latest version for the RT-N66U).
* Set a static IP address of 192.168.1.2
* With the router powered off, hold down the WPS button, and then turn it on. This will make it reset the NVRAM.
* After resetting the NVRAM, without releasing the WPS button, turn it off, so it doesn't try to boot from the main firmware.
* Make sure your LAN cable is plugged in, and get your TFTP server ready. With the Asus Firmware Restoration Utility, make sure it's it's one click away from uploading the new firmware (it times out if it doesn't begin uploading after a short while).
* Then, press the reset button and turn it on, and immediately start your TFTP server. Your router should then download and flash the new firmware.
* Wait until it's done flashing. It's probably best if you give it a good few minutes at least. Then reboot it.

But IMO, you should have no problems with TomatoUSB.
