Early on I had a lot of issues with my Ikea Tradfri repeaters. The biggest issue is they dropped off, and took a few devices with them. And since they don't show "last activity" times, I didn't catch right away that they quit responding.
When they did drop, a simple unplug and replug fixed them and got them repeating again. Knock on wood they've been solid for over a week now.
Looking in my route table, most of my devices are routing thru them, so it would make sense they bring the mesh down when they go. Den outlet, LR Repeater, and Basement repeater are all Tradfri devices
I also switched them to the drivers by birdslikewires which checks in and will report if they are offline. I set up a rule to send me a message right away if one goes MIA.
