Whenever I leave my Beryl on overnight it has some sort of latency issue.
Latest firmware 4.6.8
Running in router mode connected to another ap and broadcasting on 5ghz.
Also running Adguard, which also shows poor latency for most DNS.
Not using any VPN yet.
When trying to ping the beryl after being on overnight it will take 1000ms to respond, as well as substantially longer to load any website, (5-10s)
Setting it to reboot at 1am did not fix this. Only an immediate reboot when this happens will fix it.
Adguard only has one of the built in filter lists active. I initially tried them all and it basically bricked the router causing me to factory reset it.
I wonder if the issue still is Adguard?
Which version of AGH are you running, there's a memory usage issue within AGH that when it cannot find enough memory, it performs OOM Killer on itself,
There's a fix in this issue report:
VSZ is the Virtual Memory Size. It includes all memory that the process can access, including memory that is swapped out, memory that is allocated, but not used, and memory that is from shared libraries.
Question is, why does AGH need all of that, as it's just going to OOM as soon as it's less than halfway through that.
Iād stray away from using AGH for now. I tried but noticed it was a huge memory hog. I went with the Adblock plugin for OpenWRT/Luci instead and have been happy with it.
I'll try that, but now I see dnscrypt-proxy as a memory hog, I dont have a proxy or vpn configured right now. Did you remove the adguardhome packages? and then install just luci-app-adblock and adblock packages? or maybe adblock-lean

interestingly when I disabled manual DoH and set dns to automatic, these 2 disappeared
Tried the latest beta firmware, still same issues. But now I see I can choose how often lists in adguard update, maybe that's related. Couldnt get adblock configured correctly
happened again this morning, agh is only using the one filter, I cant find what is happening exactly, but ping to my main router is high

It would appear when using DoH or agh with DoH. but at times, pinging various devices on the router goes high, in addition to pinging the main router. I'm also always getting random high ping to my phone from the beryl, so I'm having difficulty isolating if a device is causing this or something from the isp/main router is hitting the network, or the beryl. The beryl has gone unresponsive at times, I did have a process hit 100% cpu on one core until I restarted it. that was
/sbin/rpcd -s /var/run/ubus/ubus.sock -t 30
maxing one core out for hours.
Adguard is disabled and using DoH and Wireguard and all communication with main router stopped last night, zero dns resolution, zero ping,
So I connected to main router, no problems.
Disconnected Wireguard, still can't resolve DNS,.high ping to devices, can ping main router from beryl, can not resolve anything.
Which I just realized now I guess I have to disable block non vpn usage now that I'm not using it, but why did it all quit working in the first place. Disabling that check did nothing now.
Dns is somehow broken, I can ping 1.1.1.1 from laptop connected to beryl though.

At this point, it seems like the router is just trolling me.
I factory reset it, only changes were enabled non encrypted opendns, set the ssid password, and router password, and set it to repeat my main router with DHCP to get the address for the beryl, but the mode is still set to router mode. I can not ping any other devices on the network, but I can resolve dns and access the internet. I am not using guest wifi. I have no filtering on. Adguard is off, DoH is off, vpn is off.
With or without wifi connected to the main router for internet trying to ping another DHCP assigned device on the beryl, that worked immediately before factory reset, reply is from the DHCP assigned ip of the ping from device.

update:
decided to just reflash with uboot, pinging devices connected to the router works again.
