Since I upgraded to Android 8.0 my Wi-Fi is often not connected when I startup my Sony TV. I'm fairy new to Android tv, so any suggestions?
I'm within range & have a good router.
SOLVED: under Settings / Network / Home Network / IP Controls: change to "simple IP control". It warns "this may consume more energy during standby" but it solved the problem.
I have a Mi Box 3 which had a range of issues including poor WiFi when it got upgraded to Android 8.
I finally found a solution in a program called Wakelock Revamp. I don't know if this will help. But you can look into it.
The program basically puts a wakelock on the items you select (yellow bar) and stops them from sleeping. Perhaps you can try selecting WiFi.
Here are some links:
