Hi Ray, thanks. Yes, I do use wired Ethernet. Sounds pretty strange, update can be done via WiFi and not wired LAN.
I also noticed, that in “About” the WLAN Strength is shown with wired LAN as “Excellent”. Any chance to have another line LAN showing if the connection is established via LAN? By the way: 2.1.9(7) run for my since installation without freezing.
