I have a Netgear AC2600 (yes that's the actual model number), it may or may not be a 7450 equivalent, but its close enough because that's the version of dd-wrt I managed to load on it. r47256. It is however, self-reporting as an r6800 on the status page. I'm trying to revert it to stock so I can return it, and so far nothing I've tried has worked.
DD-WRT GUI firmware update doesn't error, says uploaded successfully, but reboots to the same firmware. TFTP connection request fails every time, with every timing I can manage re: recovery mode. nmrpflash fails with "Failed to add IP address (state=3)." which I can't seem to find *anything* about anywhere online.
I've tried the stock images for:
the r6800 (what it's saying it is under dd-wrt)
ac2600 (what it says on the plastic) and
r7450 (the dd-wrt version that I managed to load onto it, regretfully now)
All fresh from the netgear site. Anyone got any advice?
When your flashing back from GUI what browser are you using?
Don't use chromium based browsers, i use good old internet explorer but ff portable is good as well as a few others.
You can always TFTP stock firmware back on
*You may find that its failing because you have changed the router model if you've not used the correct stock-to-dd-wrt files.
If its an r6800 and you flashed r6800 files it should be fine.
Try TFTP if using a different browser fails _________________ Netgear R7800 PPPoE Main Router

Like I said, I've tried every variation of firmware with tftp. No dice. For the GUI I've just been using Firefox mainline, which has never failed me yet. I'll try pushing it through IE, but I really doubt that's gonna be the thing that does it.

I returned the R7450 I got from the recent Walmart deal. I couldn't get the 2.4ghz band to stop locking up, on DD-WRT or stock.
I couldn't get the device to produce a tftp request no matter what I tried. I eventually wiped the linux partition, thus putting the router into a constant tftp request cycle.
I would try this, but it's refusing telnet connections by default after a reset, so that's out. Unfortunately I procrastinated the hell outta this to the point where I am now out of time, it's gotta be in the mail today.
@kernel-panic69, sorry my situation hasn't responded to the normal troubleshooting steps but near as I can tell this specific situation is unique, and them's the breaks sometimes. I'm gonna just send it back as-is and hope they don't care.
