I don't know, maybe the ath10k-non-ct package changed (officially) between .0 and .1?

According to the latest Linux regdb (https://git.kernel.org/pub/scm/linux/kernel/git/sforshee/wireless-regdb.git/tree/db.txt) which I believe is the one included in OpenWRT 30dBm is allowed on the channel 149 and above:
country CA: DFS-FCC
(2402 - 2472 @ 40), (30)
(5150 - 5250 @ 80), (23), NO-OUTDOOR, AUTO-BW
(5250 - 5350 @ 80), (24), DFS, AUTO-BW
(5470 - 5600 @ 80), (24), DFS
(5650 - 5730 @ 80), (24), DFS
(5735 - 5835 @ 80), (30)

Ah, yes, thanks! I'm on channel 149 so that makes sense.
Thanks for the info!

Hello,
I have an archer c7 v5 and am having disconnect issues and lost packages with ESP8266 boards.
I tested the non-CT firmware/driver but the problem persisted.
I'm using OpenWrt version 19.07.8, and I believe I won't be able to make my own firmware.
I downloaded your file and noticed that the factory.bin and sysupgrade.bin files are much larger.
Can I use them anyway?
Thanks

So, I used the imagebuilder script, how can I tell if the etc/uci-defaults script was run?
Check if that file exists: /etc/init.d/ath9k-set-txq-memory-limit

Thanks for all your help. Looks like everything is running smoothly. I'm using both radios as access points out of necessity. I wasn't able to do that with stock due a bug that would cause drops on 5G. So, it's nice to have 5G back. Does anyone know of any generic performance tweaks you can make for the V2 version of these routers, or for OpenWRT in general (this is my first jump into it).

Thank you everyone for keeping this up to date.
I installed the latest version and it did improve the issue I had before with the 2.4GHz network where some devices would not connect. There are however still devices that do not connect. I mean they do, but it looks like they do not get an IP address and eventually are dropped. Is this the right topic to troubleshoot these issues?
I upgraded my C7v2 to OpenWRT, but which one should I choose ?
openwrt-21.02.1-logd-ath79-generic-tplink_archer-c7-v2-squashfs-sysupgrade.bin
openwrt-21.02.1-syslog-ng-ath79-generic-tplink_archer-c7-v2-squashfs-sysupgrade.bin

Maybe you start with firmware images that actually exist?!
I understand that, I did use the factory-image into the TP-Link GUI.
My question is, Catfriend's build has two different bin, logd and syslog.

Take logd, as logd is also default in official builds.

Hi All,
I know it might be a stupid question or a stupid place to ask but I was wondering:
Other than issues with 2.5Ghz/5Ghz how does the C7 perform with openWRT on the wired front?
I am planning to use a C7 + openWRT as a wired router and use a TP-LINK EAP245 for the wireless part taking advantage of one of its eth ports.
I am interesting to know if it is reliable, it handles SQM well and over all is a solid choice ( as wired router ) for openWRT.
-Thanks

Should work well, if you don't have a connection much faster than 100mbit while using
SQM...
I now use a x86 box for the routing and my C7 is a AP now, but back when it was doing both, I would find that you might get to 140mbit ether to ether, and thru the wifi more like 110-120mbit, before the CPU would be saturated with SIRQ. It will run faster, but when the CPU saturates, the SQM quality will drop down, it may lock up, etc.
If you need more, find the links on here for using a RPi4 or x86 for routing a gigabit.
And, whichever way you go, consider flashing the EAP245 (good choice for an AP) with OpenWrt, since it would use the more recent Make-Wifi-Fast project improvements (getting some SQM and airtime fairness in there at the radio level)

Only 140mbit eth to eth?? what If I have 200/400 mbit connection? should I abandon the idea of using the C7 as a wired only router?
-Thanks
