LAN Not Working When Internet Service is Down
My internet service was dowm for about an hour. During that time, all 3 of my eero pro routers had red lights. I'm the eero app, e etthing showed as being offline with zero devices connected to the network. And that is what I don't understand. The Wi-Fi network should have still been functioning. But I couldn't print to my wireless printer. If this is true, why doesn't the LAN work just because the WAN is down?
Back in August, eero's software update enabled LAN persistence to where the internal network would continue working even if the internet was down. So you shouldn't have been having any issues with your internal devices talking to each other. But during an internet outage, the app will show all the eeros as being offline and no devices connected because the app is getting it's info from eero's servers and since the internet is down, your gateway eero can't relay any information up to the servers. So that part is normal behavior.
Were you trying to print from a computer or a mobile device (like a phone or tablet)? If it was a mobile device, that functionality might involve needing to route the print job through the internet in which case it would fail during an internet outage. But if it you were printing from a computer, that should've just been sending the job directly to the printer.Reply
