What settings are you running? Getting very good results with these:

Happy to report that I seem to have mine reliably (hopefully?) working at 1400 MHz overclock with build 27716 (works pretty much identically to 27700). It's been surviving multiple reboots now!
Gotchas I ran into that impacted reliability:
* Use a power adapter that can supply at least 3 amps, preferably more (symptom: random restarts)
* Keep nvram usage under 35k (symptom: brick on reboot when nvram filled up)
Here's how I fixed them:
* Find a 4 amp supply
* Add a little nvram cleanup startup/shutdown script that unsets keys with empty values:
Code:
sh -c 'for line in `nvram show | grep =$`; do nvram unset "${line%*=}"; done; nvram commit'
And, somewhat related: flash the firmware twice if necessary, because you probably want my terrible webflash off both flash partitions.
Things that will softbrick your router:
* Don't use the 1600 MHz overclock setting, even with a good power supply. Softbricked my router with 1600 and had to hard reset.
* Then... I tried restoring my 28k nvram backup I made just before the overclock. Softbricked again. So, nvram restore is broken as well. Any reports otherwise?

That's my downstairs router done as per the above steps.

4 - startup/shutdown scripts
I think the dd-wrt nvram API might need to be made a little less wasteful for this to work correctly, IMO. Lots of empty keys are filling up the nvram on this router. _________________ How to EA6400:

I assume that's something that needs done on the build by BS?

Yeah, if I'm reading this right, it'd be a change in the device-independent nvram API to not save nvram keys with empty values. I don't have a build instance set up at the minute, though, and I have no idea what this would break, so I'm hesitant to do this myself.
At the very least, unless I'm wrong somehow, the nvram should probably be restricted to 35k on this router. _________________ How to EA6400:

Hi again.
While setting up wireless to try numinits settings, I still had putty running on serial.
And i noticed that putty was filled with lines like this over and over:
br0: received packet on eth1 with own address as source address
br0: received packet on eth1 with own address as source address
br0: received packet on eth2 with own address as source address
br0: received packet on eth2 with own address as source address
net_ratelimit: 12 callbacks suppressed
br0: received packet on eth1 with own address as source address
br0: received packet on eth1 with own address as source address
br0: received packet on eth1 with own address as source address
br0: received packet on eth1 with own address as source address
br0: received packet on eth1 with own address as source address
br0: received packet on eth1 with own address as source address
br0: received packet on eth1 with own address as source address
br0: received packet on eth1 with own address as source address
Maybe its my imagination, but i think i have small dropouts whenever putty print at bunch of those errors at the same time

What settings are you running? Getting very good results with these:
What speed do you see in status->wireless for wl1? Highest I see there is 600
I have these settings, but am unable to change the channel like you have. I am wondering if I should've used the ea6400 file?
I was able to install firmware 6400 successfully but during setup had to hard reset 30/30/30 and router went back to factory firmware. Tried to install again dd-wrt following same process but it doesn't work. After installing the numinit-super-hacky-smaller-version during boot it goes back to Linksys firmware.

As mentioned, install the mini-hacked build 1st, then install the official 27716 build. On 1st bootup NVRAM was 30K+ and router's admin web response was laggy. I own a EA6200 that also has a 32K bug, and used that clean-up script:
Then I ran it (use 'run command') and NVRAM immediately dropped to 24K (same as my EA6200) and router web interface was speedy. I suppose if you have NVRAM close to 32K, I'd run that script. Running as smooth as my Linksys EA6200 and so far, honestly I think the EA6200 with DD-WRT is as good as this EA6400, but I'm still happy!!!
Am an oldie web developer and I attempted a quick Internet Explorer F12 JS debug of the 'Firmware is too large' error. I didn't bother to dig much farther, but someone more patient can definitely set a breakpoint and perhaps cause it to skip that check. I'll attempt to check it again next time I put the original Linksys firmware back on here.
Just another happy 'customer' saying thanks much to DD-WRT!!!
The flash was successful, used numinit build first and then flashed to build 27716 (went from factory firmware)
Tried to use it as wired bridged mode, working for the ethernet ports, but wifi seems not working properly. The 5GHz seems only operates in 802.11ac, all my other 802.11n 5GHz capable devices are not able to detect the SSID.

The check is actually on the router's side. _________________ How to EA6400:
