I do not say this lightly, as their screen and Bravia motion technology is very good, however their Android software implementation is absolutely terrible! They forgot to add the ability to connect USB-to-Ethernet adapters in their USB ports!??? Who does that in this day and age???
A friend tried 4 USB to ethernet devices on his TCL, ALL worked.
Another friend tried 2 USB to ethernet devices on his LG, WORKED!
Another tried 3 USB to ethernet devices on his Samsung, 2 of them WORKED!
I tried 8 USB to ethernet devices on my Sony AF9, NONE of them worked.
I wish I never jumped back into Sony land now, should have known they'd do stupid things like this with their devices, no wonder everyone is buying LG these days. At least I know where to go on the next upgrade this christmas.
If anyone knows of a workaround with Sony AF9, please do tell. Effectively I need a good 1GBit connection to the TV, unfortunately the wifi doesn't cut it due to interference and reduction in wifi speed, and the in-built 100mb (yes, really! 100Mbit old tech!) ethernet connection is a total joke.
