Hi,
I'm having a trouble with my ASUS RT-AC3100, currently the router stop to broadcasting the 5ghz signal. I'been reading a couple in a couple of forums including this one, that this problem it's related to a Hardware failure. But i want to test something, i just want to dump the CFE (i tried to do that with the command cat /dev/mtd0 > original_cfe.bin, but when i open this file with a Hex editor does not show nothing about the mac) from this Router and edit the WIFI Mac Address field. On the configurations and logs through serial console, i saw that the 5ghz interface has a unknown mac address.

Did the rest of the CFE look normal? What does `cat /proc/mtd` show? Also, have you tried running `strings` (with `grep` if desired) on the various mtd's to see if it might be stored in another partition? _________________ #NAT/SFE/CTF: limited speed w/ DD#Repeater issues#DD-WRT info: FAQ, Builds, Types, Modes, Changes, Demo#

No all the file is not legible on hex.
Also, have you tried running `strings` (with `grep` if desired) on the various mtd's to see if it might be stored in another partition?
How can i do that, i've did this command
cp /dev/mtd1 cfe1.bin
The files looks like the configuration, this file is legible.

Something like: `strings /dev/mtd0|grep -ie mac -e addr`
And check the nvram and brcmnand partitions too.
Just found visible info on mtd1, there's a mac-address different for the 5Ghz interface that the RT has

It would only be https if you have https webUI access enabled; and "ro.ut.er.ip" should be your router's IP address... you didn't click on the link and expect it to work, did you? <lol> _________________ "The woods are lovely, dark and deep,
