I think this was an issue in master a couple weeks ago. A newer build should fix it.
I just updated to
master-r13611-3f27a6e640-20200622 and the problem persists. Just to be thorough, I did change my DHCP range to not overlap the static leases, and that did not resolve it either.
Very consistent though - on every reboot the second SSID with dynamic DHCP disabled (although this may have nothing to do with it) does not give out static leases until
dnsmasq is restarted.
If there is any information I can supply to help diagnose the issue I'm more than happy to help. Other than the single message I shared showing up for every device that fails - I haven't found any other errors.
okay - I did find something in the kernel log, but don't have how relavent it is since I don't understand it much... but it lists 15 peers, and that is how many devices were connecting to the SSID with the problem:
[ 89.810162] ath10k_pci 0001:01:00.0: Invalid peer id 4 or peer stats buffer, peer: 00000000 sta: 00000000 [ 134.603196] ath10k_pci 0000:01:00.0: htt tx: fixing invalid VHT TX rate code 0xff [ 155.036645] ath10k_pci 0000:01:00.0: Invalid VHT mcs 15 peer stats
maybe that says something useful?
For the 2.4 GHz I have the wireless set to N, channel 1, 40 MHz channel width.
Is the VHT message just about it changing the width to 20 instead of 40?
From the timestamps I expect that was around the time I restarted
Sounds like something in wifi & DHCP config and the hotplug actions, nothing specifically related to my build. You might get answers from wider audience, if you would open an own thread about the it.
My guess would be that when dnsmasq originally starts, if does not yet see the wifi interface up, and fails to include that in the run-time config.
That makes perfect sense.
I'll split off into a new thread - Thanks!
Ends up the interface for the second SSID did not have force link flagged.
I must have missed this during my configuration... user error .
Long time listener, first time caller:
I'm using standard snapshot build and not this one, but this thread has the largest collection of R7800 users - I'm experiencing occasional oops within the ath10k stack.
But first, I'm offering up my sysfs.d local file that might be helpful for people using any R7800 (unrelated to the ath10k crash):

My config is 98% identical to the config file used to make this build.
Should this post go elsewhere? I did want to share my sysfs.d with people here, though, too.
Just to avoid this thread getting clogged with generic R7800 help requests, I initiated also Netgear R7800 exploration (IPQ8065, QCA9984) at the same time, so that generic R7800 discussion would not happen here.
(And naturally, you might start your own thread as you have a specific discussion topic.)
Ah thank you, I will post it over there.
Anyone else seeing these crashes? The trace in the bug is from the latest "old" build, though I think I've seen it with "ct" also.
Yeah I have them too occsionally. They were already present in backport 5.4 last year.
Surfing around trying to find a OpenWRT build that works for me or advice as to what I am doing wrong...
What I have seen is lots of Ath10k errors. I initially loaded the R7800 19.07.3 build and immediately had lots of Wifi issues: Disconnects, Inability to route to a device though it can get out to the internet just fine, Dropped and not reconnected, etc.
The 19.07.3 image for this router uses the Ath10k_pci_ct driver if I am not mistaken and had more problems when i had this loaded. I then loaded the snapshot of the official R7800 build (new kernel), but it uses the Ath10k_pci driver (no _ct). It has been the most stable so far as far as maintaining connections, but still had issues form time to time and mostly on the 5Ghz radio which is used most often.
Today, I loaded Hnyman's "SNAPSHOT r13625-d4dea7efcd / LuCI Master git-20.171.46309-c351bee" version. It has different problems than the normal snapshot or the 19.07.3 version. I am now getting terrible reliability on the 2.5Ghz radio (previously rock stable and the problems were apparent only on the 5Ghz radio). I now get this in the log:
[ 726.020999] ath10k_pci 0001:01:00.0: Invalid peer id 2 peer stats buffer [14173.484757] ath10k_pci 0000:01:00.0: received unexpected tx_fetch_ind event: in push mode Lots of these over and over...
Do not know what that is. I am recent switch from DDWRT and am still not completely conversant in OpenWRT. Can provide logs and such, but is this an issue others are having or is it me? I have Android Phones, Laptops, Rpis using the 5Ghz radio and need the RPIs to be able to get to the internet and also be able to connect to them via Avahi and http. This seems to be the stumbling block. It is like the routing gets hosed and does not restart until I reboot it.
Should I try the hnyman 19.07.3 version? Maybe a Kong build? Are all builds experiencing similar issues? Do I need to go back to DDWRT?
Still getting these. This is from last night:

None since then. Everything seems OK for now and this snapshot build seems the most reliable of all so far that I have put on my R7800. This AM when I checked, all my mDNS stuff was available on all devices and was able to reach the servers on the LAN as well. Can anyone help with the diagnosis of this error? Is it a bad driver on one of my devices? Is it anything to worry about?
I get tons of those too, I think they are harmless.
Well, it finally did it again. No connection to some wifi devices (Rpi)

The MAC is my phone. I left the house and this seemed to happen at the same time. Maybe a coincidence? Now, only some of my mDNS devices show up and I cannot get to one of the Pis though it shows as having a current lease though it is no longer connected to wlan1 (2.5 Ghz). The DHCP page shows it as having an active unlimited lease though it is not connected to wlan1.
Rebooted the device and I can access it, but it will not show up on my avahi browser. When I reboot the router it will return, but I need to reboot it to restore functionality.
I get a pretty rare crash about once every two weeks running the latest master build. Been experiencing this for about six months now.
Are kernel panics logged anywhere before the system resets so I can hopefully report this to the openwrt devs?
Also, still absolutely in love with this build/router. I'll be sticking to this until Ubiquiti adds CAKE support officially, which might be a long time. It's that good.
I've had no crashes since I bumped the lowest freq it can go to 800 MHz there were previous posts here discussing it (and I seen in the luci monitoring logs the freq constantly jumping from 300ish to 800), atm I'm using various settings gathered from the thread and had no restart in last 2 weeks or so, for the record I only use 2,4 GHz wifi on the router (for my IoT devices) and the router is only connected to modem and a managed switch.
I got this in my Local Startup in luci:

This morning, again, the PiZero is no longer connectable. This is in the kernel log

The 'Failed Lookup' error was repeated many times.
There's a new firmware file for "old"
And also the 3.10 version that has been around for a while:
The default in the "old" builds is
Not sure what the policy is to bump it to a more recent one.
And also a new "ct" version .019
Edit: Unfortunately for me .019 is worse than .018 very laggy and packet loss between 2 Macs.
Still having this issue. The 5Ghz seems more stable. It is now the 2.5Ghz that seems to have disconnects w/o reconnect.
@hugalafutro Have put your settings in the router Starte=up and rebooted. Will see if there is any difference.
After installing master-r13684-3b0f698760-20200704 and importing the SSL certificate into the Trusted Root Certification Authorities (Chrome), I still cannot https into luci without the "privacy" error.
edit: sorry, the problem is that I cannot get rid of the annoying 'not secure' message regarding the certificate.
