alzhao, I have tried different OpenVPN servers X750. Happi is using Wireguard on MT1300. So this seems to affect different servers/routers/protocols.
Happi, Is the router time still stable with the new firmware you installed? I don’t think they said the new firmware should fix this but maybe it changed something.
sammo, The VPN kill switch and processes settings did not cause a problem like this in previous firmware (3.104, 3.105) and I think alzhao said before that router processes still connect even without VPN for critical processes. Do you suggest that simply installing htpdate package could solve the router time problem?
If installing htpdate or other plug-in can keep the router time then maybe this is the best fix.
