Per title, my TV's (KDL-43W800G. Sony and their naming scheme, ugh) WiFi is always off. If I try turning it on, it will wait for 5 seconds before turning itself off again. I've searched a lot online and I've tried the following solution:

• Restart the TV
• Automatic and static IP config
• Setting correct date & time
• Factory reset
• Update to the latest OS version

but none works so far. I'm beginning to suspect that this is a hardware problem as it never had this problem before. For now I will stick to using Ethernet. Appreciate it if anyone can come up with a solution. Thanks.
