Rebooting in 10 seconds..
the crash is related to your repeater bridge tries. the ac5300 has no repeater bridge nor client bridge support. i still left it in the gui for testing. the differences on these devices is that they are all based on a own wifi firmware on the wifi chip itself which will it make impossible to implement fake bridge modes. it may work under some conditions, but officially i cannot support this.
disable it. use client mode or repeater or ap mode, everything else will likelly fail
fo the missing vht160 mode. this is a bug fix. the ac5300 has no vht160 support

But anyway, done a hard reset (30s power on, 30s power off, 30s power on) soon before and now the WebUI become fine again And yes, the 'set a password' prompt appeared fine at the first screen, just set passwords, login to the reset r33555 then flashed the r33555 again one more time. So now everything is running fine, really fine! no more wifi hangs, the router's wifi signals always response!
Weren't you saying before that you had issues in 33555? So it might be that a hard reset in 35927 might work as well?

No issues in r33555, that's the stablest ever DD-WRT for my EA2700. Only all builds after r33555 until now are buggier and buggier.
What I meant was, when I was flashing the firmware back to r33555 via the Web page of r35927, it bricked the http web interface, can't load http://192.168.1.1 by any browsers, but the router still worked, can still go through to facebook or any other websites else.
The web service bricked until I'd done a hard reset, then I could load into http://192.168.1.1 and saw the page showed me that's r33555. Then I'd just re-flashed to r33555 one more time by the web page of r33555, smoothly successful like a virgin. Now all things just are running very well, no more wifi sessions hangs.

Try using strictly AES for your algorithms and WPA Personal (not mixed). That and if you're using Windows as your client machine, and the wifi is an Intel adapter, update your drivers directly from Intel. Not having your specific router sitting in front of me to break, er, troubleshoot, I'm taking a shot in the dark here, but.

But WPA2 Personal Mixed and TKIP+AES are really running very fine in r33555 without any Wifi jams, but only hang wifi from r33607 until r35927 for my EA2700.
All my Wifi clients are android phones, an LG smart TV and a Windows 10 notebook with Broadcom Wireless Adapter. The rest 2 Windows 10 desktop PCs are wired connections. No any connection hangs for ethernet, they're always fine.

But you're defeating the purpose of wi-fi security with those settings. All of your client devices should support AES encryption. Running mixed like that is probably half the problem, but that's just my thoughts on the matter.

Not sure if to take out the DNSCrypt as an issues since i saw on another post versin 1 is "dead" and now there is a version 2. WIFI on 2.4&5Ghz works wiht no issues.

You will need to create a user id. You can also see what is happening behind the curtain here.
Can't create a user ID, captcha is DOWN. I was going to add to a ticket about Broadcom K3x regarding a nas crash and syslog time errors, because it's not just the webGUI that is spitting out weird offset times now, I get it when I 'tail -f /var/log/messages' and 'cat /var/log/messages' as well as run commands in the webGUI.

OK but anyway WPA2 Personal Mixed and TKIP+AES ain't making my Wifi transportation hang in r33555, so I don't think that matters about the wifi hang problems of the builds after r33555.
There should be some bugs or coding problems for packets scheduling, multi-tasking, multi-threading or something like so in wifi sessions, which make more and more deadlocks for wifi packets TX or RX.

The hang problems may not necessarily be related to that, but looking back at a few things, you can run WPA2 Mixed, but you'd want to run AES for encryption for security reasons. There is an open ticket for K3x Broadcom for an NAS crash, which drops the radios:
I have been trying to trap the same crash in my syslogs to post here since svn won't let me create a new account because CAPTCHA is down

Reset the time zone on my E4200 v1 to ZULU (UTC/GMT) in the Setup tab on the webGUI and have not had any wi-fi issues. I am guessing this is possibly related to the NTP / NAS issues. Don't have syslog to prove anything either way and can't register on SVN because of captcha being down, but wanted to share this.
EDIT: And of course, as soon as I post this, wifi goes screwy

But..... how...? How to find them out? And I'd fallen back to r33555 now running, so all I can do is for the next build unluckily........
And yes, the 'set a password' prompt appeared fine at the first screen, just set passwords, login to the reset r33555 then flashed the r33555 again one more time. So now everything is running fine, really fine! no more wifi hangs, the router's wifi signals always response!
