That's confusing, I've been on 35244, with a reset settings when updated to it and my 5ghz disappears from management even when disabled within 24 hours of bootup. I have the V1. I get by fine with a 841nd v9 running dd-wrt as an AP off of it but wish I could utilize the 5ghz of the c8.

My C8 is a v1. I was up to 8 days without losing the wl1 tabs on the UI.
I did move to r35531 tonight... only issue I had with upgrade was that web UI wouldn't accept connections after upgrade. I was able to ssh, so I rebooted from there, and was able to connect to UI after second reboot (no reset required/performed). I still see 15GB spikes on bandwidth monitoring, but ntp updates are no longer flagged as errors.
So far so good... but 2 hours is not exactly a complete burn-in!
I had r35531 running but had an issue with openvpn - terminated on launch with cert issue. My certs expire end of the month so could just be age..... will troubleshoot at end of month....
Also lost UI when loading firmware - had to reboot via telnet and then restart webservices (probably switching off and on would also have worked but box is remote).
I have over 3 days now with 33006 (I reverted), and with just the 5ghz active. It disappeared from the UI, however it still works and works well. That is better than the newer build where when the management of it disappears it also goes dark. Will see how long it stays active like this. I restarted the web service and that did NOT get it to show up again.

Interesting result for 33006... I did set-up an external syslog server to see if I can find the errors on 35531. I had stopped using wifi on it, and had no issues, so wifi appears to be part of the stability issue.
I'll be monitoring for the next few days to see if I can capture any errors.
We got this router on sale that we wanted to use as a Wireless repeater and we have issues with the 5ghz radio since we installed ddwrt.
We didn't know the CPU wasn't the same architecture as our main router (Archer C7) so we can't use WDS, only Repeater Bridge but that brings more issues.
We know we cannot go back to the stock firmware for the moment but will it be possible in the future? If I understand correctly, there was one single guy that was able to craft a special .bin file for tp-link routers to install back the bootloader and he wasn't able to do it for the Archer C8?
I am probably giving a very basic and ignorant post but is there any way to downgrade my current firmware to Archer C8 V.2.0, so I can install DDWRT? Would that be safe? I currently have archer c8 v3.0.
The reason is I need to configure a static arp in order to configure the WOL (Wake on Lan). To do so I would need remote access to Telnet which is not open apparently on the current firmware. I can already turn on my machine remotely but the only case it is not working is if the electricity goes off and the router resets.
Any two answers would be great, either if I can install DDWRT on this version of hardware or if you know a way to put a static arp on this hardware. The tp-link configuration to bind mac address and IP is already done.

No you can't downgrade. That's hardware version not firmware. _________________ R6400v2 (boardID:30) - Kong 36480 running since 03/09/18 - (AP - DNSMasq - AdBlocking - QoS) R7800 - BS 31924 running since 05/26/17 - (AP - OpenVPN Client - DNSMasq - AdBlocking - QoS) R7000 - BS 30771 running since 12/16/16 - (AP - NAS - FTP - SMB - OpenVPN Server - Transmission - DDNS - DNSMasq - AdBlocking - QoS) R6250 - BS 29193 running since 03/20/16 - (AP - NAS - FTP - SMB - DNSMasq - AdBlocking)

I am up to 13 days on r35531 without a required reboot. I haven't lost the 5 gHz pages, and the wireless error counts are much lower than the previous versions I have tested.
Good results so far with 35767, using 5ghz. I tried one difference from any other trials - setting the cpu clockspeed to 600mhz. I hadn't even noticed you could move it down from 800mhz in the administration tab until recently.
Will see how long it lasts, 24 hours now and wifi didn't vanish, it did on this build prior to this cpu speed change.
And if someone figure out how to install on v3 as reported by this guy, let me know that i'll be more than happy to try at home too on my Archer C8 v3.
Tried to contact this user through PM without success.
Its looking more and more like my reliabilities with DD-WRT and the Archer C8 v1 was due to a lower quality unit than other people possibly received. Leaving the CPU clock speed set to 600mhz has made it run nicely. (thanks to whomever made this option available)
The management website would regularly drop the 5ghz, sometimes the 5ghz would remain usable but not visible in the UI, but I'm past 3 days now of uptime with no problems. I've also noticed that xbox party chat hasn't had problems either and its fairly finicky prior to this setting.
Perhaps this isn't unique to me, worth a shot if you have reliability issues with a unit and the option is there to drop the clock speed.
