I had similar issues with my LG TV in bedroom, after updates, lots of problems, luckily I now either set my devices to notify me of update and then wait a week or two before I allow update to take place, when I cannot control updates, my ASUS router has option to disallow that device access to internet, so I allow internet access only when I want to update say the vacuum cleaner or fridge etc. (only joking about vacuum cleaner)
