I’m on a RT-AC3100 and Asuswrt-Merlin. Have been for a long time. Came from a RT-AC87U (ugh). Started Alpha and Beta use last year.
Did a dirty update to 384.9 B1 from 384.9 A3 last Sunday. This morning woke up to a cold house, that’s weird. “Smart” thermostat was still set at sleep temp. Thermostat app says it's offline. Wife said no internet but TV works as I got my 1st cup of coffee. Router not responding. Logged into switch and it’s fine but no traffic. SSH a no-go too. Then router logon page pops up. Logs showed cable modem renewed lease at 10pm last night, router (as always) reports modem does not play nice with IP renewal, then pages of associate/disassociate events. All 2.4Ghz wireless clients are offline. So, reboot. After about five minutes a few wireless clients are connected. So full reset and manually configure everything. Better but not good. Two of five 2.4Ghz clients will not associate and pull IPs. Went nuclear and went back to 384.8_2. After another reset and manual config I have all wired and wireless clients alive and happy. And I have a functional network map. Haven’t seen any AiP IPS hits logged yet but I did get one TrendMicro warning pop-up so far.
So, any ideas of what occurred? I’ve never seen such a mess.
