firmware downgrade F6400

Post by zsoltyszasz » Fri Sep 29, 2017 9:32 am


I have a problem with my TV since many years. My model is UE46F6400AWXXH and firmware is at version: 2126. It disconnects from the wireless network if I watch a movie from my DLNA server or HBO GO. I also replaced by myself the wifi module to a new one but problem is totally the same. I am thinking of downgrading the firmware version to the lowest version possible. I am not sure but I think with the the first firmware all was ok. Can you guys help me? Or if there is a fix without downgrading the firmware that's also OK for me. I tried everything which I saw on the internet but no fix/tips are working. On 2.4Ghz and "54g" my TV works ok, but If I move to "150n/300n" or 5ghz then its not stable (it disconnects after 5 minutes from wifi). My other TV which is an LG on same wifi network works like a charm. Can you help me?

Kind regards,
