I have 3x ST wifi hubs, model ET-WV525 (running plume). This afternoon all my wifi devices started to go offline. A reboot resolved it, but only for a few minutes.
My devices successfully connect to ST wifi, but exhibit “internet down”-like symptoms. Doing some troubleshooting from my laptop while connected to ST wifi, turns out I can ping Internet IP addresses (such as Google DNS, 188.8.131.52), but all my DNS queries fail.
Wired devices that go straight into my router work without issue. If you are connected into the main ST hub Out/LAN port, you experience the same issues as when connected to ST wifi. I even borrowed the main ST hub In cable, which comes from my router, and my laptop performs fine.
Tried to manually set different DNS servers on my laptop wifi adapter, no change. Pointing nslookup to different DNS server IP addresses (that are pingable) all fail for wifi connected devices.
Wired devices are OK. I’m fairly confident this is a ST wifi/plume issue.
Done the reboots of all devices, issue persists. ST support told me to do a “long reboot” - leave the hubs powered down for 10 minutes, no change.
Any troubleshooting ideas are appreciated. Thank you.
