Purchased a cheap R9000 that has no 2.4ghz wireless, running stock Netgear firmware. i use mesh wi-fi discs so the wi-fi was not a problem to me.
But for some reason it will not connect after DD-WRT is flashed, can't even ping it.
it will TFTP back to any stock version no problem and run fine (without 2.4ghz obviously) but connects and runs fine, tried TFTP'ing 2 different stock-to-dd-wrt.img files same result not able to connect or ping router after flash.
i thought about opening it and trying ttl serial cable breaking the CFE and erase nvram and then tftp but unable to find tutorial regarding strip down.
question can i connect serial ttl cable to r9000? if so anybody know how they come apart lol?
i know nothing about the history, assume something corrupted the nvram or something, your thoughts?
cheers in advance

well i ve no idea about your issue, what could be the cause of it... i also had a faulty R9000 with no radios and flashed it with an old Kong factory to DDWRT...it was ok...just reset the stock firmware..and flash it via GUI, here is the old Kong flash file...

After flashing upgrade i can no longer reach or ping the router, same as flashing from stock, if this was bad blocks would it show here?
Kong file 25mb
BS r45632 37.5mb

Sorry I'm useless, do not have R9000 yet, but this reminds me of another thread. R9000 can't enable Wifi

Mine has all radios dead, and I just flashed the most recent BS build from Voxel's latest with no dice. There is a hardware issue with this SoC for some reason, perhaps a bad batch of routers shipped out or whatever. All the lights on mine are on nowadays, but nothing is broadcasting. I may roll back to an older stock firmware and flash the Kong image from this thread and see if it decides to act nice or not, but I'm highly doubtful. I think it's going to wind up being electronics recycling fodder. I do want to try connecting serial to see what is going on, though. I haven't messed with checking things out via ssh yet.

I am able to flash voxels R9000-V1.0.4.47HF.i which seems to be 35.4mb, i can reach router and it works, minus the 2.4ghz radio, the 5.0 broadcasts but when i try to connect it seems to attempt to connect but then fails same it without wireless security.
All i want on this is a 2021 DD-WRT build i would like the 2.0ghz cpu for running a vpn, seems odd it flashes BS latest DD-WRT builds but it does not boot correctly, its looking like i need to connect the serial and see where its stopping booting after DD-WRT flash.
I was hoping to find a guide on taking it apart but i can't seem to find anything on net about it so it may be trial and error.

If the radios do not work properly, it may hang during the auto-channel scan.

it does this before the network is started so that you then have no access to the box

(but this is only a guess)

try 44715 (a slightly older image with 1.7Ghz clock speed)
maybe it doesn't like the 2Ghz so much

Did you ever try this? My understanding is that these routers will not behave when being flashed EVEN to a later factory firmware without having their nvram cleared. This was the explanation for why so many users tried to update to the at-the-time latest Netgear firmware and lost their radios. Ultimately I have read you must use the serial cable to clear the nvram and then flash to whatever, and then clear the nvram again. But I've never found a tutorial on how to do this with the R9000 that makes me comfortable enough to try.

I also recently tried reverting to the factory original netgear firmware and then tried flashing dd-wrt, but now I can't access it at all, but that could be my n00b attempts to telnet and ssh through PuTTy failing me.

I wrote a document on setting up VLANs on Netgear R9000.
While not exactly what you're trying to do, i think being aware of certain aspects of R9000 may be helpful.The link is in my signature.

Yes i got the R9000 running on current builds (sadley no radios still) and with help from DWCruiser PDF got the Vlan's working.
https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=333216&highlight=

From memory, the r9000 would except the last R9000 Kong build (linked at the beginning of this thread), but no further, but it would allow me to flash back to stock. As you'll see from the link above the r9000 is now running the latest dd-wrt version.
FYI: I tried clearing nvram via serial didn't help me restore the radios. As I don't require the radios this was never an issue for me if they worked or not.

Thank you very much for taking the time to reply. This is still relevant to me as I can set my R7000 behind the R9000 as an AP. Daddy gets the Ethernet connection. XD

Here is a shot in the dark.

Netgear R9000 has a button (second from right) to turn off/on Wifi.

A possibility. Could it be that flashing to another firmware source (i.e. from stock to DDWRT; or vice versa) this function was somehow engaged, rendering its wifi partially disabled.

A definite verification would be: First restoring the R9000 back to Stock f/ware, then verify if wifi works. Pressing down the button and hold for a few seconds.

If Wifi indicator lights are on, and you can connect to it, you know there is nothing wrong with its wifi. It should work in DDWRT, surely.
If not, you have nothing to lose, but flashing back to DDWRT.

P.S. I have came across two used R9000 units, the wifi works fine with no issue. BTW, the wifi on/off button also works on DD-WRT v3.0-r51043 std (12/19/22).

This could be. I have to figure out how to unbrick mine. After I reset, flashed original stock then dd-wrt I lost access to it. I can't seem TO SCHOOL or Telnet to it on default ports.
