Hello,
i have try to activate WED on /etc/modules.conf with wed_enable=Y , but after reboot wifi,pppoe both didn't work anymore.I didn't test more if anything else not working so i deactivated it.
I am using the 24.0 firmware.
Its hard to know if the crash happened due to WED and not something else, especially without a stacktrace/log.
On the github tracker from OpenWrt there are also a couple crashes related to packet sizes and multicast or in multi psk environments.
Just to highlight how random these can be 
I use around 10 to 18 different devices, from these devices only one manage to crash wifi on the router but on very erratic times, sometimes i can use it a couple of hours some times for almost a week, and often more than not it crashes every 3 minutes.
So for now maybe it can be usefull to diagnose if it is device specific its not a full solution but that can work, the mt76 still is affected heavily on these issues.
These are issues im referring at here and here, did these time out messages also occur?
For me was like this : i activated Wed on modules.conf and rebooted. i waited and waited nothing happen, no wifi network was up. i connected laptop with lan and i have seen on the mainpage the pppoe was also disconnected and the message i got was to use a cli command something with mod*** /dev/ppp 8 2 something like that was the command. After using it the pppoe connection was successful but no internet on devices. also wifi was down. i have removed the wed activation line from modules and reboot again and wifi was back also Internet on all devices.
And the upgrade was done without keeping the settings?
^ if this happened then it makes sense it didn't work, the configuration is different, for example the references to the wifi devices are changed inside the config, maybe some core configuration from gl-inet aswell and function scripts.
As for pppoe it is possible it can be a bug, i only can confirm this is not happening for me on a OpenWrt snapshot which is more recent (r27060-15b39ab986) than the oem firmware from GL-iNet.
The upgrade to 24 was done with clean settings. I wanted to be like that. After the upgrade i have try to find a solution to improve my wifi speed on 5ghz because i have 1gb fiber connection with old router Xiaomi AX3600 openwrt v21 on wifi i could hit 930-940 mbps easily but on Flint i cannot download more then 650-750mbps even if Flint 2 has better specs then Xiaomi.
And that why i keep try to optimize the wifi seetings and also the system.
WED was configured wrong because i have written the old command in the modules.conf the wed_enable=1 but now is something like : options mt7915e wed_enable=Y but also i am not sure if is the right one because i have seen no improvements but very poor pppoe connection after so i disable it.

This seem the correct one, pppoe should be unaffected by WED, the only thing what might interfere is when something like qos or sqm has been used, WED bypass this for wifi clients.
WED is only for wireless, its another type of offloading and still very experimental.
My suspicion might be the mtu settings in correlation with pppoe, do you also use a vpn too?
i think the mtu for pppoe needs to be 1500 or 1492, and for wireguard similar, pppoe can also be 1508 but i would suggest testing with the lowest, some isp don't allow beyond 1500 mtu anyway.
It can also be the gl-inets hardware accerelation.
Thanks for info. I will need to do some extra tests. Somewhere there is the solution but i must find it
