After following the install instruction by "butterworth" of page 67 (Many thanks for the guide). I successfully get DD-WRT installed on my EA6400.
However, I realized that the 2.4G rate just keep staying at 5.5Mbps which obviously slower than stock version. But the speed is pretty good at 5G.
But both are giving the same slow rate. Crying or Very sad Crying or Very sad
The current version I flash is DD-WRT v3.0-r33257 std (08/29/17).
I also noticed that the Received (RX) and Transmitted (TX) from Wireless Packet Info would show errors which there is 0 error on my TP-Link-941N with DD-WRT.
I did try to dig the solution from this forum but the speed issue seems not related to the settings. Could anyone give some suggestions?
I tried to follow instruction by butterworth on page 67
The prep step says to install the latest firmware twice. Mine has 1.1.40.172334. Linksys support page shows EA6400_1.1.40.176337_prod.img. But the installation will end with error of invalid image. What should I try to install here?

This is why I gave up on DDWRT and went back to stock.
The speeds from ddwrt were pure crap and unstable even on 5ghz vs. bone stock linksys firmware.
While Linksys fw is barebones and doesn't let you tweak anything, speeds are rock solid. No slowdowns, and no need to reboot. But too many neighbors have 2.4ghz routers, and my other computers only have 1x1 wifi cards, so I can't get more than 72mbps connect rate on those.
All you can do is to keep flashing older DD versions until you find one that works.
I wish there were a way to hack the 2.4ghz to force 40mhz, like tplink does it.

Too many of your neighbors have 2.4ghz, so you'd like to set your 2.4ghz to 40mhz.
All your neighbors as considerate? _________________ I am far from a guru, I'm barely a novice.

Anyone who flashed Merlin has the same issue?
Speeds are fine here, running X7.5. I am getting 72.2 Mbps on RX and TX, and this is in a congested Wifi environment.

You can't use any third party firmware as the Linksys firmware series from 1.1.40.17xxxx and higher has signature checking to ensure that only certified Linksys firmware is flashed.
It is possible that the Linksys image is corrupted or is missing the signature or that Linksys has used a different signature?
New Merlin build now: X7.6, it seems that the code has been synced with 380.67
Details from Koolshare Thread:
【Linksys EA Series】 includes the following models:
EA6200
EA6400
EA6700 / EA6500v2
EA6900

I finally switch to Merlin x7.5 and it stays at really good speed for both 2.4 and 5G. But I personally like DD more that Merlin .
However, I can't see there is any new amendment adding to DD firmware of EA6400 to be honest .

Yeah I honestly like DD-Wrt more, but the wifi was just very unstable when I tried it before.
It's been a year since I've moved on from DD-Wrt; I would have hoped it has improved, but I doubt it. I might give the dd-wrt kong version a shot when I've got some free time.

It does seem that the Merlin x7.6 firmware is somehow missing.
First time heard about "Kong" version, hope you will have some good news on that version.

Hey all, I just wanted to say a huge thank you to everyone who spent time and energy sleuthing out the details needed to make DD-WRT run well on this hardware! Your trailblazing efforts made my experience smooth and trouble-free.
I picked up a used EA6400 for $10 recently as an upgrade for my aging E2000. Luckily, it still had the absolute first official firmware (1.1.35.148797) so by reading up carefully I was able to get DD-WRT installed and running without any hiccups.
Before doing anything with firmware I completely tore the unit down to address the thermal issues. There was a thermal pad under the main heatsink, but the die still wasn't making particularly strong contact. I sanded the nuts on the heatsink down so they were just barely shorter than the height of the die. I then removed the pad, cleaned the die and heatsink, applied a small bit of Arctic Silver 5 paste, and very carefully tightened the screws down just to the point of being snug. I also removed and cleaned under the two heatsinks on the reverse side (beneath the radios) and reapplied them using a generic non-conductive thermal grease.
Finally, I flashed the last non-locked official build (1.1.40.160989) twice to get everything ready before the DD-WRT install process.
I'm currently running Kong's 29300M with the customized Koolshare CFE and everything's humming along wonderfully. Temps are great at low 60s for CPU, and high 40s to mid 50s for the radios. I've also got some 6dBi antennas and U.fl connector pigtails on the way for an external antenna mod (did the same with the E2000 previously.) I'm loving the increased performance with the dual core Cortex A9! My old E2000 was holding back my 100Mbps download speed even at a 453MHz overclock.
So, a hearty cheers and thanks again to everyone who made this possible!

Hi I am weeding through many pages here and not
doing very well at coming up with an answer.
It's obviously not a "supported" device.
Is and can or will anyone here give me a quick answer
as to how I can get DD-WRT on this device?
Is there a compiled flashable image that will work?
I'm also not clear on if the EA6300 is the same as the 6400 6500 etc.
I'm getting bits and pieces of this picture but not
the full answer.
I'll continue reading and try to determine an answer
on my own.
But please help if you know or can give me a summarized answer and what I should do next.

Besides reading through the thread in full (which is absolutely a good idea given the many quirks of getting DD-WRT on this router) I found the following the most helpful:
Butterworth's summary and guide on page 67 of this thread:
From what I understand the EA6300v1 and EA6400 are identical hardware. Apparently there's a non-v1 EA6300 as well, and that's actually a different unit.
The biggest thing to be careful about is not accidentally updating the unit to one of the later official Linksys firmware builds that includes signature verification for any future flashes. That'll lock you out from being able to make the change to DD-WRT. The last build that's safe is 1.1.40.160989, which I found is still available on the Linksys servers (they just don't list a direct link any longer, I found it by manually hunting around and trying the build names listed in the changelog):
If you're on anything earlier, make sure to disable automatic updates while it's still got the Linksys firmware. Even better, just keep it disconnected from the internet entirely until you've completed the whole process.
And guess what my buddy who has the router just did...
LOL!
Thanks so much for your help and for the reply!
I think we are screwed.
I'll have to read through this and see if there is a
way out of that.
I'm plenty comfortable getting onto the board
And reflashing chips & stuff the harder way
At this point he's planning on getting a new router
It's old,
and it's just for fun.
We don't really care if we brick it trying.
I'm getting a Q87-EA6400 (6300V1) for cheap and will try to install DD-WRT on it.
The seller was getting rid of it because the router was rebooting everytime someone connected on wifi. Ethernet was ok.
The router was on 1.1.40.176337 firmware and the seller said he was not able to install any other 6300 firmware. He was probably not trying 6300v1 firmwares.
Then he installed firmware 1.1.41.183873, from EA6700, and wifi was back to normal. BUT, everytime the router was rebooted, it entered a boot loop for some minutes, requering the user to reset it manually. Also the leds were not turning on.
I believe this behavior is due to the 6700 firmware.
So, it's a 6300v1 with 6700 firmware. The seller never tried a 30/30/30 reset or anything else but official firmwares.
Hope to be able to install DD-WRT with the methods in this thread.
